Another thing: Rainbow should be the only pony naturally to do a sonic rainboom. The reason for that is her colour palette. Imagine if another pegasus, such as Spitfire did it. Would the flame shape and the rainbow still be rainbow coloured or would it change to Spitfire's colour palette? Well, if it would adapt to Spitfire's colours, it wouldn't be a rainbow, and if it would stay rainbow colours, it wouldn't look as good. When Rainbow is flying seconds after the sonic rainboom has occurred, we can see that the rainbow is pretty much being drawn from her rainbow-coloured tail. So if a rainbow would be coming out of Spitfire's orangish-yellow tail, that wouldn't quite work. So Rainbow Dash was destined for this at birth, which might have something to do with genetics.
The reason the wonderbolts were incapable of doing this in the Sonic Rainboom episode when attempting to save Rarity is because they're just not as good as Rainbow. Flying isn't all speed, it's also agility and *motivation*. Keep in mind whenever Rainbow did a sonic rainboom, she was being motivated by something. Now, remember how Twilight saved Spike in the same way? Or when some of the school students saved Oona the Yak in the same way? The reason they didn't cause a rainboom links to my first point, which is that only Rainbow is capable of doing so, even if others are flying just as fast as her and being just as motivated as her.
Let me know what you think!

Yeah, if a sonic rainboom contains an explosion of magic, maybe you actually need to be rainbow colored in order to activate it. Like, what if only ponies like Rainbow Dash and maybe her dad can?


Very interesting.

good example of science and magic working together.

Magic IS science,we just don't understand it


Pinkie pie said, "if a Pegasus pony LIKE RAINBOWDASH gets going fast enough it causes a sonic rainboom."  YOU LEFT OUT THE TWO MOST CRUCIAL WORDS IN THE QUOTE. But then again it really just backs up your theory.

@shaunpocalypse According to a daspacepony video about the Friendship is Magic timeline the first "sonic rainboom" was done by a Pegasus (one of the first Wonderbolts) and thus they became an honored group of Pegasi in Equestrian culture.  In "Sonic Rainboom" before seeing Rainbow Dash make a sonic rainboom it was like the Mare in the Moon, described as "an old mare's tale"

Like Rainbow dash just mean pony with Rainbow Mane. This means theoretically, every pegasus could pull an explosion of their color. Although this is quite hard to achieve, you also need to rainbow mane to had it called rainbow mane. <br>This means someone's has pulled out the same thing except it is not pegasus with rainbow mane (and probably a pony with one colored mane and then somebody make a theory that if someone with colorful mane could pull it out.

@Emily Sims yeah see the problem is he forgot to mention anything about the fact that it was already called a Rainboom before it was ever done, so it must have been done before by another Rainbow pegasus, otherwise it's just faulty lore

@Mystic Rosey or it could be that rainbow dash is the example, out of the majority of the ponies in the mane 6

@zMøonlight It shows that not any pegasus, but only one like rainbow dash or as fast as her, can pull of the rainboom.

I fail to see why those three words change anything?

Three, not two. 'Like Rainbow Dash' is three words.

BroadwayBandito oh my god yes- I cracked up at that-


If rainbow got her cutie mark from a sonic rain boom, was her destiny to make a sonic rain boom if a ponys cutie mark is their destiny.

@paraYEETs and me DUDE I POSTED THIS YEARS AGO BAHAHAHA AND U DECIDE TO PICK THE DAY I WANTED TO RELIVE MY CHILDHOOD AND WATCH MLP

Her destiny is to be a wonderbolt, or to be a racing/fast pegasus

All the Pegasis "controls" the weather and not all of them have Cloud Marks...

I think that RD's CM could be related to her destiny with the Sonic Rainboom, what is the thing that helped all the Mane6 to get their CMarks and indirectly helped to save Equestria from the villains timelines...

In my HeadCanon one simbol in the CM mean something more about the destiny of the pony, and the CM with three equal simbols could mean the job, personality, what the ponies likes, and other things...

Sydney Griffin no and I know I am replying to a year old comment but rainbows destiny was to one fly fast explaining the lightning bolt part of her cm and the other is control the weather explaining the cloud


“How do sonic rain booms work in the first place”<br>Intro: FRIENDSSSSSSSSSSSSSS!

“How do sonic rain booms work in the first place”
Intro: FRIENDSSSSSSSSSSSSSS!


when twilight is an alicorn she kind of does a rainboom her cutie mark appeared in the sky!

@Lil'Autistie that's what they mean by alicorn magic its way easier to say than " magic from all of the tribes"  and  twilight transforms into an alicorn so it would be magic from all of the tribes to make the "boom" of magic aka twiboom

luvxox undertale, Hazbin hotel,gacha etc

@The Rymples Well the 6 wizards before Celestia and Luna did it, didn't they?<br>And if Celestia and Luna each have Earth, Unicorn and Pegasus magic in them, that amounts to 6 as well.

@The Rymples Well the 6 wizards before Celestia and Luna did it, didn't they?
And if Celestia and Luna each have Earth, Unicorn and Pegasus magic in them, that amounts to 6 as well.

@Lil'Autistie So... If we had a Earth, Unicorn, and a Pegasus, they could move the sun and moon?

@The Rymples But alicorns don't have 'Alicorn' magic, they have magic from all the pony tribes, so technically it was just the Pegasus and maybe Earth magic entering the body

It kinda resembles the rainboom ngl. Twilight can't control much of the alicorn magic that the princesses gave to her since her horn or her body can't contain that big amount of alicorn magic maybe that's why Princess Celestia has a big body or idk lol

No, It was because her alicorn magic was out of control

Some people say that she died and was reborn as a alicorn. One of The Brony Notion's videos say it was Starswirl's spell/enchantment.

Some people say that she *died* and was *reborn* as a alicorn. One of The Brony Notion's videos say it was Starswirl's spell/enchantment.

The Rymples I think they are referring to a different ep.

Not even a sonic boom there, it is all the alicorn magic entering her body with unicorn magic leaving, all it is is the process of a newly formed alicorn.

But  did you know they call it a "rainboom" because it's supposed to mean "rainbow" dash is the ONLY pony to pull it off and when Twilight's cutie mark appeared it was because of her magic.

She used a spell to do that. You can see her horn light up as she takes off. No sonic boom, just a magical flash effect.


I think it might have something to do with drags relationship with speed regimes.
Between sub sonic and super sonic, there exist a regime know has trans sonic, we're drag increases alot. This drag drops after a certain point. This is where my theory comes in
When rainbow dash finally enters trans sonic speeds, her pegasus magic starts to build up, trying to meet the demands of keeping at speed with the induced drag. Once the drag drops to a certain point, the high demand of magic is gone, but there's still alot of magic built up.
                                  This is where my second part comes in. Has aircraft go faster, the air heats up the surrounding outer sheets of material on the ever accelerating plane. Because pegasi are just flying flesh, I suspect that there magic also forms a heat shield around the then selves
 Now back to the magic build up. Since the magic has to be expelled somewhere, and it's expelled through the shield. The shield then expells the magic again, along side the sonic rainbow, and thus, you get THE SONIC RAINBOOM


When she travels at the speed of sound (mach cone 1), she collects a mass amount of water on her, and when she travels faster than speed of sound, she hits mach 1 plus, the sound waves merge into a single shock wave that travels at the speed of sound. That's when she goes faster and faster. The max speed she's ever hit is mach 10, which is 12348 km/h, 3430 mph and 7600 mps(it was calculated). The sound waves force the water outward making the rainbow, so the feathers quickly disperse the water around her. (The sunlight does this when it hits the water)

So yeah, it doesn't have anything to do with her mane


Side theory: depending on how much magic they lose or what aspect they lose, that's how much they fade


I actually would agree with the whole magic correlates to the color. My own pegasus OC Nightspeed (who I've headcanoned as dash's older brother) is another pegasus able to perform the boom, but it's dark blue and black to match his coat and mane, I've labeled it a sonic darkboom. It's the exact same thing, just a different color, and the whole pony magic theory would fit perfectly with it.


Its worth mentioning that the speed required to perform a sonic rainboom must be much higher than that of breaking the sound barrier. Note that a mach cone is formed before the rainboom itself and the sweptback angle of the cone indicates that she is flying well beyond Mach 1; perhaps even in the hypersonic range (~Mach 3+).


You forget to mention how the Sonic Rainboom was an old tale because of when celestia defeated and banished Luna(nightmare moon) she created the rainboom that people thought was a myth

No just No, she banished Nightmare moon with the elements.

Aracelli Padilla yes I am replying to a comment 2 years old but no that was not a sonic rainboom it was the elements of harmonys magic power

The power from old relics not Pegasus magic


I do prefer the old look.. the "back to school" segment was pretty cool and yeah, everything that you stated was pretty solid for a magical horse cartoon. the animations where spot on as well, and congrats on the 100k. Great job!


Interesting. There likely is a combination of magic and science involved.


Let me sum up this video a little better: "physics exists, therefore the countless hours I have spent on Wikipedia are useless, as i am applying basic science to a cartoon TV show and I conclude nothing makes sense here nor has to."


I agree with the pony color part. Remember when twilight has all of the alicorn princess magic? She also had a trail, but in her own colors. I think this would be the same for a rainboom if she did one. But out of curiosity, what would twilight’s boom be called?


That magic aspect of the Sonic Boom parts makes sense since it's their natural magic that allows them for Accelerated flight ,speed ,and weather manipulation.


You Make Really Good Theories I Love It :D💜


i know this may sound totally weird...but I have been in love with ponies since I was a kid in the 80's.  I think it is sssooo cool that a guy has a pony page...rock on dude.


I love your videos! they are very accurate! h deserve way more sub's!


You have my support on this theory. I think it’s true.

By the way I love science.
I also liked the way you described the boom of the Sonic Rainboom.😊😊😊


I noticed another thing with the colors matching the character. I've seen with most unicorns (Rarity, Starlight, Sunset, etc.) that the magic glow of their horn is a color of the pony (rarity's is either her cutie mark or eye shadow, sunsets is eyes, starlight's is the greenish blue in her mane, etc.)

Although in the first seasons they couldn't decide on twilight's horn color (light pink and the pink of her highlights and cutie mark)


Nice explanation of shockwaves in simple terms. - from an aerospace engineer.

Magic boom on the other hand… I got no idea what that’s supposed to mean. - from a non-magician.


As she reaches the sound barrier speed, she goes 343 km per second. Before she reaches the speed, the barrier starts to bend and break, causing that wind-fire-thingy as she goes faster. Once it breaks it explodes.


I've been thinking, could a pegasi like Twilight or Fluttershy perform it? If they could, what would it be called? What colour? I have no clue what color it could be because neither of them leave a trail of color behind them when they fly, unlike rainbows. Maybe Twilight's would be the same as in the example.


Again, RLYoshi did a video on this. It explains that rd is travelling fast enough to pick up water, but she can't be travelling at the speed of sound because she'd hit the ground. She then stops a bit, and that means the water flings out in a band. Check out the video, I can't explain it.


I like this idea. Pegasi magic has always been a great topic of debate, and I've always theorized that it's what allows Rainbow Dash to actually BE the fastest flier in Equestria. If she has a passion for anything, it's flying—more specifically racing—and as we've seen with unicorns and earth ponies, a pony's magic tends to align itself with that pony's passions and desires. It would make sense that Rainbow Dash's pegasi magic is concentrated toward the area she has the most passion for: Speed. It would also explain why she leaves a rainbow contrail behind her when she exercises her extreme speed. With that all in mind, it's no surprise that a Magical rainbow would occur upon generating a sonic boom


i think you're right. but do you think the season 3 ender where twilight flew threw an explosion in the shape of her cutie mark was because of a spell she intentionally did or is it the same type as the rainboom?


Twighlight actually did two Sonic rainbooms at a summer Sault celebration and when casting her spell like you mentioned but I believe that the summer Sault celebration  rainboom was a special one because it was in the shape of her cutie mark


Awesome video man. I've been waiting all week for this! I always wondered how the sonic rainboom worked. But I think Twilight did her own "sonic rainboom" in a MLP episode once. (Not in the one you mentioned. Don't remember the name, but it's in one of the older seasons) It's cool that you changed your OC a little! It's new and refreshing to see a MLP animated in a different way! RAINBOW DASH IS ALWAYS AWESOME! 🌈


Unlike some of the comments, I like your new look.


I know this video is older than when I’m commenting but I’m new to your channel and I have another theory that may hold some explanation.  I like the magical boom theory but what if Dash’s boom was so powerful that the shockwave bunched up water droplets and a combination of compacted water, light rays, and how fast they were moving allowed the droplets to catch on fire in the same way a diamond is formed mixed with the light rays from the sun and Dash’s residual magic created the sonic rain boom.


I know that in the episode where Starlight meets Trixie, dash and Starlight are talking about the wonderbolts, and rainbow dash flew off really fast, that caused a really loud boom. Maybe that was the sonic boom portion of the rainboom. If she went any faster her rainbow trail woulda made the rainboom, rainbow.


The speed of The energy is slightly slower than the wave of the "magic" the colour reflects off the pony with the speed of light that makes a impact ball that slowly grows and explodes the energy is very large so 100% of the rainboom is energy out the impact sphere the sphere contains 3.8% water 100.5% of white light 399.0%of coloured light and <br>30% nuclear powerd light and electrics the explode  with the energy of light and eletric the pony moves at the right speed to activate the nuclear area

Your theories are brilliant xD

It does make me wonder how much time goes into developing them, and how much backtracking for supporting evidence it entails. How do you even choose your focuses? Would love to hear back from you on these things.

Great show as always /)


How would the rainboom be known as the RAINboom before rainbow did it, though? It'd have to be done before by a rainbow pony or something! Any ideas?


Now the really interresting question would be, if you theory is correct and magic is a waves like the sound, since the boom & rainbow happening together does it mean that the speed of magic and sound are the same ?


That makes so much since! I love it! But do you think that her kids or if she taught other ponies how to do it then they could do it?


Just a side rant/theory about the magical element of the Rainboom... Perhaps the Rainboom has a unique element of magic to it - an element of desire, fate or hope.

As a filly, Rainbow Dash didn't expect to perform the rainboom but achieved it through her desire to win, her desire to be the fastest she could ever be and to show everyone she is. Along with the desire to win the best young flyers competition, Rainbow Dash hoped she could save Rarity in time. Again the rainboom allows RD to catch up with Rarity and the Wonderbolts in time (literally almost at the ground!), magically fulfilling RD's desire to save them.

Applejack had the desire to go home and find her purpose and the rainboom directed her home and to her cutie mark, her fate being working the apple farm.

Rarity had the desire to make her designs shine and stand out. The rainboom opened the rock of gems giving her inspiration for glamorous costumes, sealing her fate as a fashionista. (Not sure if the rainboom would be connected to how her horn knew where to go to find the rock -  anyone else have any ideas?)

Fluttershy had the desire to fit in to a crowd where she didn't feel so weak, small, blocked out and to be listened to. The rainboom helped her realise she could communicate with animals (or help unlock the ability). This sealed her fate of working and caring for animals.

Pinkie Pie desired to have a life full of joy, colour and happiness. Perhaps she felt her fate was to work at her family rock farm for the rest of her life (since her relatives were into rocks) and that there wasn't much of a world outside the rock farm (she seemed pretty young compared to her sisters and the Mane 6 so maybe she didn't leave home much before seeing the rainboom?). Anyway, the rainboom brought her happiness and showed her that life wasn't as bleak as she thought it could be (or as bleak as a rock farm?). Pinkie then wanted to spread joy and smiles because she wants everyone to feel as joyful as she did seeing such an event (and for others to not feel sad, low and hopeless like she may have felt). She realised through comedy, friendship, cupcakes and parties, that she could bring smiles to her fellow ponies.

Twilight had the desire to prove that she was worthy and ready to attend the school of magic, inspired to be like her idols, Starswirl and Princess Celestia. The rainboom fulfilled Twilight's desire by boosting her magic to an abnormal level for a unicorn, especially at her age. This sealed her fate as the Element of Magic and Princess of Friendship because of her capability of using various magical abilities which, along with her knowledge of friendship, allowed her to finish Starswirl's scroll.

Since the Mane 6 all shared a mindset of desire and belonging at the same moment, that may have been what connected them during the rainboom.

The rainboom at Cadence and Shining armors wedding could symbolise their desire and fate of being together and ruling the Crystal Empire (even though they didn't know it yet because it hadn't appeared).

Finally, when Twilight offers her friendship and guidance to Starlight Glimmer whilst a filly version of Rainbow Dash performs a rainboom, this could symbolise Starlights reform, acceptance of friendship and fate of her becoming a major part in the study of friendship (the thing she had despised since she was left behind by Sunburst).

Just an idea! Probably overthinking it way too much though. Anyway, I hope you enjoyed!

That Rainboom is a powerful source of energy
I tried researching it Recently but I haven't cracked its secrets
It seems to be a mix of fate and magic


This may not be too important, but I had to tell you that you are my favorite MLP analyst. I really enjoy the interesting questions you think of and find answers to and you've inspired me as well. Your style of analyzing is so unique. I look forward to your videos all week long and check your channel constantly on Thursdays for your new upload. Thank you for making such great videos!

@The Brony Notion Aw, thank you! I'm so glad you saw this!


I love how we are making lore out of a kids show. (I'm not saying its weird that were making lore for a kid show, I watch MLP too XD)


In addition to all that, I found a headcannon that kind of makes sense. Maybe you can do a theory on it? https://s-media-cache-ak0.pinimg.com/236x/38/91/1a/38911aaea7e835aca8cb1e987ac3db39.jpg


Any movement in our atmosphere creatures pressure waves aka sound waves. These waves cause vibrations that our brains translate into sound
The faster you move the more compact the waves in front of you become
Once you hit mach 1 (the speed of sound), you're traveling at the same speed as the waves in front of you, and that creates a mach cone around you. The smaller the cone's angle is, the faster you go.
At this point, the pressure waves are so tightly packed together, breaking through them by going faster than the waves themselves, causes a shock wave. That's when you hit mach 1 plus. The fastest she's ever traveled is mach 10. And that's so f***ing fast. Like, you can't even see that. Not by any chance.
The boom is so powerful that everything that comes into touch with the huge wave as it spreads, can feel a super loud sound and a huge wave shaking everything, kind of like a "smooth" earthquake.
It's so powerful it'll probably kill you, but Dash can handle it just fine. Now that's some impressive sh*t.


I think Rainbow Dash went so fast that when she ran into the cloud, the speed was so fast that it shot the water droplets every where, and also ran into a light barrier, thus making it go in all directions, thus a big rainbow circle going in all directions( Not realistic, but it's FANTASY )

Oh, and I like that "educational" video.
(I know that stuff)


since we got a view on pegasus magic I hope the show soon (or maybe has already without me noticing 0-0) shows some sort of earth pony magic... I mean they are magically great with nature and stuff..


Ooh! Ooh! Idea!

In The Return of Harmony, as mentioned, Twilight effectively makes a Sonic Twiboom on the ground.
She was a unicorn at the time.
So if pegasi create Sonic Booms in the air, and unicorns presumably on the ground, where do earth ponies create it? Using of course a perfect scenario where earth ponies could in fact perform Sonic Earthbooms.

I think it's the magic wave theory (lay lines) which penetrate all reality if these work via vibration or other stuff (can't explain with out an essay) then pegus manipulate these so they can control weather, really it's mainly so clouds and water vapour are solid to them... this would mean that at a certain speed they compresses spewing a power but still invisible boom of magic... the color  is do to this magic manipulating photos... I do not think that a different pony would have a different rainboom...


I absolutely adore how this is consistent with my headcanon of Equestrian magic having its own quantum particle the properties of which can be manipulated (kind of like Pratchett's "thaum"); it's really plausible that for Pegasi it operates more or less like a photon, except dispersing as magical waves rather than electromagnetic ones. Assuming they travel at a speed slower than light for whatever reason, of course, though it doesn't necessarily have to be 343m/s (which might explain why Dashie's mach cone before hitting the Rainboom is Mach 5-esque).


I've always thought it was because of after imaging. But this would make a lot more sense.


I missed listening to people analyze My Little Pony. Since DigiBrony moved to anime, BronyCurious moved to.... idk what he does now.  Saber Spark moved to cartoons in general, and Anytony C is mostly silent, it's nice to know that there are still some people that care about the fictional science of this universe. I forgot what drew me to MLP in the first place. The world. This world is just so fascinating to think about, research, and analyze. It feels like such a real place as much as Westeros or Middle Earth. I think this level of world building in a cartoon is only matched by Avatar... or if there are more world building cartoons out there, let me know! I'd love to watch them. (And before you say it, yes I know Steven Universe and Gravity Falls... I just haven't got around to it yet) But I know Star Vs the Forces of Evil is looking like a good cartoon. And maybe there are some new ones coming out.


The fact that Rainbow Dash seems to have to lead with both front legs while her failed attempts were when she was leading with only one leg may be related to how divers lead with both arms usually, with the bullet-like shape making it easier to break through.  Am I right there?


This was the first explanation I had of a sonic boom that I properly understood.

Now I'm 13 and a science nerd.

Baby steps, everybody, baby steps.


+TheBronyNotion being a pilot, this is my  area of expertise. A vapor cone is basically pressurized air in the form of a cloud. It is this because of the water vapor is warming up, and at the verge of breaking the barrier, it instantly cools forming a water vapor ring, so it could technically be a refracting process because of the compact water vapor spreading out


I have a theory!

What if Pegasi produce sound through their wings? Like when Scootaloo flutters her wings they sound like a humming bird. And yes I know we can't really hear Pegasi flap their wings but if you listen closely you can. But idk that's just my theory


As far as the rainbow,  I think that it is just a huge wave of light and clouds that have been moved by the audible blast. #VIBRATIONS ARE SOUND


I think it’s not so much that magic itself works like waves, but a large burst of magic can create a wave-like effect.


I just wanted to say this episode was really cool


I have a theory. Maybe (because in the episode revealing rainbow’s parents and her father has a rainbow mane) her father was the first to do the rainboom, or one of rainbow’s ancestors. Maybe rainbow hair is a genetic mutation and a dominant gene?


Now I’m curious, what is Rainbow Dash’s top speed or cruising speed in meters per second? I don’t know if it’s possible, we would have to measure how fast she moves every second in certain scenes, and that would require some kind of yardstick to measure by. Thus, if we can establish canon measurements for Rainbow, we can thus derive her speed. Alternatively, we could figure out how to get m/s from “wingpower”, which I believe might be the only measuring system we’ve ever seen used. We can assume this is a unit of power, like horsepower, and so is probably equal to a unit of energy (or a unit of length times a unit of mass) per a unit of time (probably seconds). Rainbow is stated to have generated “16.5 wingpower” at what we can assume is normal cruising speed, so are there any way physics buffs out there who might know what a “wingpower” is and how fast she’s going?

Dear Hasbro,

If you ever see this, hire me.  You can reply to this message to let me know.  I promise I'll proof-view all your animations and guide them to be a lot more physically realistic.

Sincerely,
An aerospace and mechanical engineer.

Short answer: Wing-power is nonsense, and despite my best efforts, I can't calculate horse manure from it thanks to some lame animation on Hasbro's part.

Long answer: Wing-power is presented as a linearly scaling measure of ... something .... Time to figure out what that something could be.

We know it is a linear measurement because Twilight takes the time to add all of the pony's wing-power together in the show "Hurricane Fluttershy".  Had wing-power been a logarithmic measurement, or a measure on some other scale, you could not add wing-power the way they do in the show and get a meaningful result.  This is good news, as linear measurements are pretty easy to work with.  This also bad news as you will see in a moment, assuming I haven't put you to sleep yet.  You are a person of either great mental fortitude or great procrastination if you are still with me (or both; go do something productive when you are done reading this).

Let's look at the perhaps obvious possibility: wing-power as a measure of power.

Power can be defined as...

eq. 5
Force * Velocity = Power

... The force in this case is aerodynamic drag.  The velocity is whatever we can measure from the video.  Through a lot of video math on a particular scene of the show Hurricane Fluttershy" (link to scene: https://youtu.be/YK7vf0OkmRQ?t=492 ), iPhone shenanigans, and some help from Wikipedia on the height of small pony breeds (127 cm from front hoof to what is effectively their front shoulder blade), I found that Rainbow Dash clocked in at 10.66 m/s when she recorded 16.5 wing-power.  This is pretty slow, but that's what the animation showed according to my numbers.  It's possible my scaling is off, but to achieve higher speeds our mane characters would need to be bigger than real horses... honestly, bigger than elephants just to reach typical car highway speeds.  One important side note for later on: Rainbow Dash's head takes 5 frames to cross the screen when she flies in front of Twilight and the wind-power machine, and MLP was animated at 24 frames per second.  Just keep this in mind for later.  A few more important numbers:

Frontal area of a small pony (minus its hooves) is about 0.3 m^2 = A
Drag coefficient of a racehorse (no jockey on top) is 0.57 = C
Still assuming Earth atmospheric conditions, so air density is 1.2 km/m^3 = r  at sea level

Now we have what we need calculate the power (in Watts) Rainbow Dash needed to fly at 10.66 m/s.  Aerodynamic drag can be calculated by the equation...

eq. 6
0.5 * r * V^2 * C * A = Drag force

... According to eq. 5, we can multiply eq. 6  by velocity to get power...

eq. 7
0.5 * r * V^3 * C * A = 147.9 Watts

...For perspective, a typical car motor puts out 111,000 Watts (or 150 hp) at peak power.  You would not expect your car to reach Mach 5.  If you put your car motor in an airplane, you would not expect your airplane to reach Mach 5.  Even in thinner atmospheres, like on Mars, 111 kW is not going to get a human sized object to Mach 5 without some radical advancements in drag reduction technology.  But whatever... it's a cartoon... we press on!

So we know Rainbow Dash used 147.9 Watts in the scene I linked above (assuming we are in an Earth-like atmosphere).  We also know she recorded "16.5 wing-power" on the same flight.  If we assume wing-power is a measure of power, then we can create a conversion factor between Watts and wing-power...

eq. 8
147.9 Watts / 16.5 wing-power = 8.96 Watts/wing-power

... Alright, so we've done it.  We calculated what wing-power means and converted it to human-understandable SI units... right?

Along comes Fluttershy to ruin all of my math.

Let's do all of this again, but this time on Fluttershy's run of 2.3 wing-power (link to scene: https://youtu.be/YK7vf0OkmRQ?t=808).  Immediately a problem arises on review of the video of her flight.  Fluttershy took 5 frames to cross the screen while flying in front of the wind-power machine.  This is the exact same amount of time it took Rainbow Dash to cross the screen.  That means both Rainbow Dash and Fluttershy flew at 10.66 m/s!  This ruins everything.  If they flew at the same speed, then they both experience the same drag force (assuming equal drag coefficients, which is a reasonable assumption).  They thus needed equal amounts of power to fly.  So if both Fluttershy and Rainbow Dash used 147.9 W to fly, then how did they get different wing-power?!?  Conclusion: wing-power is not a measure of power, but of something else.

Could wing-power be a measure of circulation?  The wind-power machine does capture airflow rotation given it's shape and location next to the track, and circulation would be one way to determine how hard the ponies' wings are flapping, so maybe this is a possibility?  Unfortunately, calculating circulation for anything other than a rotating cylinder is a bit complicated.  Moreover, because Fluttershy flew just as fast as Rainbow Dash did (according to the animation), no calculation of circulation will show that Rainbow Dash has some superior metric of flight performance over Fluttershy.

Could wing-power perhaps be a measure of lift?  Doubtful.  Fluttershy and Rainbow Dash are most likely about the same weight.  Again, these numbers would come out to be the same and would fail to explain the discrepancy between Fluttershy's and Rainbow Dash's wing-powers.

Could wing-power be a measure of wing-thrust?  No.  Thrust directly and equally opposes drag in steady flight, and we already established the drag on both pegasi is the same.

It can't be a measure of specific impulse.  There's no way to record energy consumption in any form.

Basically, wing-power is some made-up metric that makes absolutely no sense when you start to dig into it.  Had Fluttershy's animation been slower than Rainbow Dash's, then things would have made much more sense.  But since that is not the case, I cannot draw any conclusions as to what wing-power means.  It's horse $#&%.

Conclusion
So today we learned that Rainbow Dash can apparently fly at Mach 5, has fur and feathers that can withstand over 1,700 K without burning up into ash and dust, and can pump out an amazing 16.5 wing-power... whatever that means.  We also learned that when Fluttershy actually tries to fly and trains her body, she can accelerate just as fast as Rainbow Dash can (but not all the way up to Mach 5)... and wing-power apparently doesn't record that fact.  But most importantly, we learned that no one in Hasbro's animation team knows the first darn thing about aeronautics.

I hope you learned something here.  If not, I hope you either already know all of this stuff (in which case, hello fellow aerospace engineer!  I would love to make your acquaintance!),  or I hope you now know that there are worlds of information out there yet for you to learn, so keep learning!  Learn how to be a better person, a better family member, a better friend, a better employee... just don't stop improving.

Now get off your butt, shut off YouTube, and go do something productive.  I actually can't believe you read this entire thing.

Well...  I might be a year late to reply, and years late to the video, but better late than never.

...And better a dissertation than a blurb, so get comfy.  You're probably gonna learn something.

The questions you've posed boil down to 2 things:
1. What is the fastest we know Rainbow Dash can fly in units we humans can understand?
2. What does 16.5 "wingpower" equate to?

1.
Thanks to the Mach-angle formula, we can easily find out how fast is the fastest we've seen Rainbow Dash fly.  The sharper the cone around her body, the faster she is flying, according to the relation...

eq.1
M = 1 / sin(angle) ;   where "M" = Mach number, and the "angle" is measured from the visible edge of the shock to the centerline, or half the angle from one visible shock-front to the other.

... The sharpest angle I measured was 11 degrees (or 22 degrees if measuring between both visible shock fronts, which we then divide by 2 to get 11 as our shock angle).  Plug this into our equation and we get...

(drum roll please)
a Mach number of about 5!

We know that Rainbow Dash is flying fairly close to the ground, but not close to sea level.  Equestria is very clearly shown to be mountainous terrain.  As a reasonable guess, let's say Ponyville is at 500 meters above sea level.  Considering that Rainbow Dash didn't perform  the sonic rainboom until well after she broke the sound barrier, this means one of a few things:

Possibility (a).
Assuming that Rainbow Dash is flying on a Standard Day (technical term for saying global, annual average atmospheric conditions), the temperature at 500 m is 11.75 degrees Celsius (calculated by linear interpolation using Standard Atmospheric Tables: https://www.engineeringtoolbox.com/standard-atmosphere-d_604.html ).  We have an equation that gives us the speed of sound for a given temperature in any ideal gas ("ideal" meaning negligible inter-molecular interactions).  That equation is...

eq. 2
S = sqrt( (ratio of specific heats) * (specific ideal gas constant) * (absolute temperature) )  ;  where "S" is the speed of sound.

,,, The ratio of specific heats for air is about 1.4, and the specific gas constant of air is 287.05 Joules/(kilogram * Kelvin).  Our temperature of 11.75 C can be converted to Kelvin by adding 273.15, which gives us an absolute temperature of 284.9 K.  Plug this all into the equation, and we get...

 a speed of sound 338.4 m/s

Multiply the speed of sound by our Mach number of 5, and we discover that Rainbow Dash is flying at a wicked...

1,692 m/s = 6,091 km/hr!

Needless to say, this is a cartoon.  At high Mach numbers and at altitudes below 20,000 m, anything flying at Mach 5 has a very toasty nose... literally.  Air is compressible at high Mach numbers, and as the air is compressed, it's temperature rises.  For compressible, isentropic flows, this temperature can be calculated by the equation...

eq. 3
t = T * ( ( 1 + 0.5 * (M^2) * ( (ratio of specific heats) - 1) ) )^(-1) )  ;  where "t' = real temperature,  "T" = total temperature (a contrived value describing kinetic and thermal energy of the flow in one number),  and the ratio of specific heats still equals 1.4 for air.

eq.4
The equation can alternatively be rewritten:
T = t * ( 1 + 0.5 * (M^2) * ( (ratio of specific heats) - 1) )

... We can first solve for T by plugging in our absolute temperature of 284.9 K and Mach number of 5 into eq. 4 to get...

T = 1,709 K!

We can then consider a stagnation point on Rainbow Dash's body (any point where the air must stop completely, such as the tip of her nose and hooves, or the leading edges of her wings).  At a stagnation point, the Mach number is 0, therefore, the total temperature equals the real air temperature.  Meaning, that...

Rainbow Dash's nose and wings are being hit with scorching 1,709K air!

 That's hot enough to melt aluminum, steel, and even the most heat-tolerant stainless steels!  Nothing less than titanium or carbon-ceramic composites can survive this temperatures for any length of time (what is this pony made of?!?).

Possibility (b).
We are not on Earth.  The setting of MLP: FiM very clearly takes place in another universe (and we know this for certain thanks to MLP: EG).  On this other version of Earth, the atmosphere need not be the same as that of our own Earth.  The atmospheric composition, pressure, and temperature could all be completely different.  In this case, most of the Math I have done for possibility (a) is effectively meaningless.  The only thing that we know for certain are that Rainbow Dash can hit Mach 5, but without any knowledge of this other atmosphere, we can't know how fast Mach 5 really is.  It could be 100 m/s or 100,000 m/s for all we know.

This ends the answer to question 1.  The answer to question 2. is in the next reply because it didn't fit in one post (I didn't know YouTube had a character limit, but I definitely found the limit today).

I like the theory but sadly in Season 7 episode 7 "Parental Glideance" it shows rainbow dash and the other members of the wonderbolts breaking the sound barrier during one of there training sessions and it was just a normal sonic boom.


Hold on a second you can be a very good teacher of science  👨🔬and students will love to learn with you


The rainbow is made by the boom being so loud and destructive that it broke the pixels of the drawing tablet.


to add to your theory, in one of the mlp episodes they say that no pegesi can do the sonic rainboom, so i do think that rainbow dash is probably the only posible pony who could do the sonic rainboom


The magic boom could be similar to a sonic boom but instead of sound waves, it’s light waves. Where as there is a small amount a water in the atmosphere it could reflect off, it could also reflect the light spectrum off of any sweat the Pegasus pony produced at going at a high rate of speed due to as in a few other episodes, we saw that magic produces light. Or it could pick up the extra colors reflecting off of the mane or tail of the pony. Since there isn’t really a light blue in Rainbow Dash’s sonic rainboom, nor is there the same shade of purple as Twilight’s coat in her failed fail-safe spell. Also, I don’t know if anybody else noticed this or not but, Rainbow Dash’s mane and tail have small specks of light similar to the ones Princesses Celestia and Luna have, which could be any excess magic to amplify the colors that are reflected into the sky.


I think she is the first pony to pole off the sonic rainboom because she is the only pony with rainbow fir twilight on that one episode wher terec got out she went so fast purple magic was left behind so she would of done a purple magic rainboom so the coler of the fir the coler the rainboom


First off ....

How did they even know about it?

And if they did
.... then there was another Pegasus that did the same thing.....

And it also caused a shock if you understand what I mean ... science.
It's not really magic .

And her hair is short not that long ....

But it is part of her hair .
You know the rainboom


i think that when a pony moves fast enough an is about to break through the sound, the colour of that pony's mane and tail is partly blown off into the sonic boom. That explains how no pony has done a sonic rainboom apart from rainbow dash.


I wonder if any Pegasus perform anything similar to Rainbow Dash's sonic boom. Who knows - there might be a new Pegasus introduced (sometime in My Little Pony's latest season) who's got the grace and speed to do such a thing! Also, am I the only one who's curious about how & why ponies can play guitars and banjos, despite having HOOVES???


OK, here's my theory about the Sonic Rainboom.

We all know Rainbow Dash could be the fastest pony in Equestria. And Rainbow Dash wasn't the only pony who did the Sonic Rainboom. Know how I know? Because one of the ponies from a long time ago maybe pulled off the Sonic Rainboom. And the Sonic Rainboom is based on the pony's color. But it was usually meant for Dashie. And the Rainboom was supposed to be a rainbow. That's why it's called a Rainboom. But when other ponies do it, it's just called a Sonic Boom. Because they aren't rainbow mane colored. When Twilight did her Failsafe spell, a Sonic Boom appeared out of the spell. Which is described in the Brony Notion's video. But it's called a Sonic Boom. Because it isn't a rainbow. That's why the Rainboom is based on their color. So it makes sense that Dashie was only one meant to do a Sonic Rainboom.

But then again, that's just a theory!!! A Sonic Rainboom MLP Friendship is Magic theory! :P This might be true, but if it isn't, reply and correct me. Thank you!


Guys, stop flipping tables and jumping off of bridges because of this new design! I already expected it. This will happen allot. DUH! HE'S A CHANGLING!


Every elemental sonic boom
Energy : Sonic Energy boom
Hydro : Sonic Hydro boom
Magic : Sonic magic boom
Rainbow : Sonic Rain boom
Lightning : Sonic Light boom
Hellfire : Sonic fire boom
Light : Sonic sun boom
Ice : Sonic snow boom
Cyclone : Sonic cyclone boom


I guess that Sonic Rainboom has more powerful than a nuclear bomb that wipe out the whole town. Has you ever seen “The Day After” where nuclear explosions were depressing? That was sad about happened in the film, and it was based on the events of the nuclear crisis, and that was from 1983.


aw man i was hoping the science lesson would've lasted longer


I've seen pictures and in real life jet fighters actually doing a sonic rainboom. Apparently by flying high and fast enough the ice crystals that form on the plane will fall off and correct me if I'm wrong because I seriously think that this is the wrong phrase but the light refracts...? Or maybe reflects of these ice crystals (been a long time since I studied light) and creates a rainbow and when a so nice boom happens a mixture of crystals are ejected from the plane which creates that cloud effect. Bit more sciencey than that but I'm sure you get the picture so if the sun is in the right position and so is the plane you can create a sonic rainboom.


Okay, maybe I'm going a little bit crazy... but don't we see what Twilight's Sonic Magicboom would look like when she does her flyby in "Princess Twilight Sparkle, Part 2"? Or is that some spell that she casts rather than going through the trouble to go supersonic (which we see she's able to do, later on in "Twilight's Kingdom, Part 2")?


that theory is great and  looooove the  new back ground!


I have to disagree with Pinkies explanation. When Rainbow dash does the rainboom, we clearly see a Mach Cone formed around Rainbow Dash already, which means she is already traveling faster than sound. My theory is that Rainbow Dash is getting close enough to the speed of light that it causes a Sound Boom type effect for light. Anything with Mass cannot reach the speed of Light, but can reach relativistic speeds. I think in this universe when something with mass gets close enough to this speed in an atmosphere, it causes a sonic boom like effect with the photons around them istead of sound waves. (Vs battle Wiki proves that Rainbow Dash moves relativistic to the speed of light.)


Tbh I always thought that she was simply traveling faster than the speed of sound and the rainbow accrued due to her colouring... thought that was obvious


+Twilight Sparkle Congratulations on becoming an alicorn!


Does this mean, that in the season 4 or 5 finale with Tirek, Twilight, if she had chosen to, could've flown fast enough to make a sonic twiboom thing? Cos she CLEARLY went at like 100 mph with all the alicorn magic, AND she had the tail trail thing that rainbow dash has when SHE goes really fast. So do you guys think that she could've made a sort of sonic twiboom? and WOULD you call it a twiboom? What do you think it would be called?


Starting off with a sonic style title screen

NICE

I think that it's possible that it's power come from how much the pony put into it. then the color comes from the pony.


theres a problem tho, why would it be called a sonic "rainboom" if the event has nothing to do with RD in particular, are we supposed to believe that the name came from another pony who invented it who just so happened to be rainbow colored?


I own a more logical explanation.
Pegasi, Earth Ponies, and Unicorns all have their own unique magic, I know this because of S4 Ep25-26 as Tirek gets magic from all Unicorns, Earth Ponies, and Pegasi. And if you have a pegasi that goes fast enough, it leaves their own unique trail, Rainbow Dash just happens to go fast enough to create a trail easily. and her trail just happens to be a Rainbow, the faster she goes, the longer and thicker the trail gets because more pegasi magic is going in each part of it. The magic energy of the pegasi that makes the trail spreads on the sonic boom that creates all the colors, but this also explains why she leaves a rainbow so thick that it stays there longer then a normal rainbow should, it is also so thick you can see the colors of the rainbow as if it was a table that your painted the colors in order on. Btw if you noticed, when she goes fast enough there is rainbow infront of her too, I believe I can also explain that, sense her body is going so fast the preasure waves are all touching her because of her speeds, the magic that makes the trail spreads on the preasure waves too, which also explains how the magic spreads on the sonic rainboom. btw I would says the your theory of a sonic boom is correct, but the rainbow part is just no.
In the same seqson and episodes of how I knew all types of ponies has magic, Twilight gets enough magic to go so fast that she leaves a trail too, which shows that not just Rainbow Dash has her own unique trail, and in S3 Ep17 Thunder Dust had a trail too, and thwy were all faster at the times then ponies that didn't have a trail, which meant that my theory of the trail is actually pegasi magic is true.


Well it's kind of obvious magic has to do with the color of the character I mean look at maleficent her magic appears to be green her eyes appear to be green the gem on her staff it's green so no wonder rainbow Dash's Sonic rainboom is rainbow


Do you think Daring Do could perform a Sonic Boom but their own version??


Ah yes Science and Magic Working Together for Friendship

Seems Legit


What happens if 2 or more ponies make a sonic colorboom (it's only rainboom if it's RD) at the same  time? Will it be 2 colorbooms or 1 big multicolored one?


I think it could be a link to be honest since she is the only one seen to pull it off. And also i have to agree with the rainboom/rainbow theory. Rainbow dash seems to be destined to be the one to pull it off. Also that was how she got her cutie mark. <br>Sooo wouldn't she have some relation to it or something?

This is what happens when you let adults with no imagination watch my little pony and they will try to explain everything with science


i think there world is so soaked in magic that it builds up in layers like earths atmosphere and the sonic boom just causes a ripple in the surface of said layer and magic just pulls color from the point of origin or the point of agitation <br>(the point from which it is being manipulated)

Wasn't music magic in equestria girls? if so, a sonic boom, wich is made of sound/music, would be made of magic.


My theory is that pegasi have magic, not as apparent as unicorns, but still magic this magic however does not give them the ability to fly i believe that is down to there phyical form (wings)science, in the episode twighlit's kingdom we see him absorb their magic this could of been that magic and because this drained their energy this caused them to not be able to fly, we didnt even see them try to fly so perhaps if this magic was drained but they still had the energy they could still be able to fly. So the rainboom that rainbow dash did was pure science as we see sawtooth explain it, but the colours that we see was all down to magic, another good example of this was when twighlit performed a similar trick with magic which was in her colour, this only shows that what rainbowdash did was her inner magic.


0:49
I finally understand how she moves fast as she can for a SONIC RAINBOOM!


I believe a Sonic Rainboom can only be pulled off when the true magic of friendship is present. I mean think about it, when Rainbow Dash created her first sonic boom when she was a filly, the Mane 6 all got their cutie marks at the same time. Then in the other episode, it was only when the non-pegasi ponies of the Mane 6 were cheering her on that she was able to do it again. Just a theory but HAY whatever. :)


Just putting it out there, but what if "sonic rainbooms" happen when a pony excels at what they do best, like with twilight, that spell caused a sonic rainboom, but more for her talent. I call it a sonic rainboom because I have nothing better to call it. Please at least consider this. Thank you


I want to see the sonic rainbow is actually something very special according to Rainbow Dash that is actually something she pulled off even when she was only a young kid and then when she was an older full-grown pony

What you did for lightning this is sonic rainbow I think it looks pretty good it matches her a lot I'm just saying!


Rainbow dash isn't the only one before her there was one other pony<br>Ok and if you look at the wonderbolts when they flt they leaf behind coloor so if the boom spreads out maby it just takes the clour with it

The ponies all across equestrian practically eat drink and breathe magic. I believe that rainbow simply broke the magical  sound barrier and it caused a visible rupture in the magic of equestria.


Better science lesson about sound waves than what my teacher taught me


SCIENCE basically u gotta be faster than sound, and a loud boom can be heard. I think rainbow's sonic boom is rainbow because her mane is rainbow. Simple


I suppose you could say the sonic rainboom twilight sparkle did could be called a sonic magicboom. And I am talking about the one she did to try to fix discords magic.


What if it depends on tail colour and the firey part is because of the shape of the tail


I would think it had something to do with her rainbow trail when she flies and the sonic boom pushes that trail outwards and that is why no one else had done it but I don’t know.

+Mary Kolbas I didn't like it at first but then I realised it looks more Changeling like, especially with the face. It actually looks pretty cool.

+Sydney Byrns   Yea XD but it's kinda cool :3

+Shadow Fox  eh it just doesn't look to good to me but it is cool.

+AlanaLPStudios I agree with you, it kinda scares me...


I'm a fan of rainbows but I love sparkles even more so twilights boom is so perfect and prettier


This is very plausible. Thinking over to Friendship Games, where there was a lot of magical malarkey going on, I noticed two instances where magic waves appear to exist. First, Twilight's pendant. It's told she made the pendant to track 'EM frequencies', which are waves. Her device tracks waves, and waves are caused by energy, so who's to say magic energy can't cause waves? (For how her pendant actually trapped magic inside itself, I'd consider that the pendant only tracks EM energy and when tracking magic it acts different due to the magic acting on it.) Later in the movie, when Midnight Sparkle opened up rifts to Equestria, how could it be that Sunset could drag the magic out of the HuMane 5 when it had already been taken out? When the rifts opened, magic waves radiated into the human world and restored the magic inside them. Equestria is a magical place, and I'm guessing that with all the magical ponies in that land, magic waves are emitted by them into the air and fill the land.


Something I wonder about the sonic rain boom : as you see the rainbow trail merges with rainbow dashes tail, so if a different colored pony could do it so if twilight did it would it be purple? And while I was typing that he said it would WOW.


ok it's alright that you changed the shape a tad BUT YOU BETTER STAY A CHANGLING MAN!!!!!!!

my science teahcer showed this in class because she needed a way to teach us without all of us throwing paper airplanes everywhere lol


Wow! This new look is my favorite one!!!!!!!!!


wouldnt celestia be able to have a similar effect?


Somehow I think all this is the most likely explanation to how Rainbow Dash made the Sonic Rainboom.


Why is it that whenever your intro says Friends I think of the series Friends T^T


Sawtooth feeds off of the love of his fans. That's wonderful.


I would like to point out the show states that a sonic rainboom is an old mares tale so prosumably others have done it before in the past, just rainbow dash is the only current one to use the technique.


Even Twilight made a sonic "rainboom" at the end of episode princess twilight sparkle part 2 but in her own colors or cutie mark to be precise so the theory of the main colors is possible but magic has to involved because how can twilight be able to fly fast enough when at the beggining of princess twilight sparkle part 1 she could barely get off the ground


So just something to point out..

If starlight did change the past or if RD never did a sonic rainboom that makes me believe that if she never did one equestria would be taken over by: Nightmare moon, Discord, Tirek, midnight sparkle,  starlight, queen chrysalis, sunset shimmer, pony of shadows, king sombra, the sirens and in the my little pony movie Tempest shawdow and the storm king.

Well for nightmare moon, tirek, queen chrysalis, king somra and the storm king the mane six either needed to use the elements/ the magic of friendship or just  helping the ppl that needed to save the day.

With starlight, sunset, midnight sparkle, pony of shadows, discord and tempest (fizzlepopberrytwist) they needed to show them the magic of friendship instead of using magical rainbow lazers, they now are all good now instead of invading equestria with a human zombie teenager army, causing a land to be chaotic, you name it.

 SO if RD never did that sonic rainboom those villians could have never been defeated or become on the good guy team.

And if twilight failed her exam celestia never would have made her her pupil and everypony would have never got their cuite marks and made friends, stopped equestria from beeing taken over ect....

So basically rainbow saved all of equestria and does not know.
Thats why i believe  the Sonic rainboom has a very important role in equestria.

@dragonflyzMC I know I men't the style I wasn't really thinking about that when I was writing it I was focusing on the joke rather than the context. XD


Can we just acknowledge the fact that Dash is the only being who doesn't have any super power that can pull off a sonic boom on her own? With no extra abilities.<br>I mean, Flash is not normal, Sonic isn't normal. They all have super powers. Rainbow doesn't have any of that, she's a normal pegasus like Fluttershy, and she pulls it off on her own, all with her own abilities. If that's not wild then i don't know what is

Have you noticed if you fly fast enough you leave a trail with the color of your mane that is how rainbow caused the sonic rainboom.


Makes sense. Also I found a picture of Pinkie Pie performing a sonic rainboom. And as a wonderbolt. I was searching for images of Pinkie Pie as a Pegasus. I don't know why though. But I saw something very disturbing. Pinkie Pie cut off Rainbow Dash's wings and had them sewn onto her body in one of the pictures I found. <b>shudders</b>

Rainbow dash isn’t the only pony that has done it. It season 4 episode 2 at the end twilight goes into the sky and does a rainboom. Also in season 3 episode 2, the crystal heart does something similar to a rainboom


Since scootaloo can't fly does that mean she's not magical? D;

Scootaloo and Bulk Biceps are both Pegasus/Earth Pony "Half Breeds". Bulk Bicepts can fly because he is using his wing muscles AND his Pegasus magic TOGETHER to stay airborne. Scootaloo would need to work out her wing muscles and tap into her Pegasus magic if she wanted to at the very least FLY. She may not have enough to do a sonic rainboom EVEN while running.

+alex the trader  Lauren Faust said scootaloo can't fly

+Loralee Nepomuceno I don't think she will ever be able to fly in flight to her finish there were ponies her age flying

Maybe her mom/dad is an earth pony/unicorn so her magic is a weird

I think she CAN fly, but not now, maybe soon?

I think that magic is the main reason she has issues, since bulk biceps can fly and his wings are really small. maybe her parents  aren't pegasis.

No, her wings are too lazy to fly

Jk it cause her wings can't bring up scootaloo cause her wings are too weak..

+Loralee Nepomuceno <br>Maybe pegasus flight magic is channeled through the wings, but for Scootaloo there's some sort of interruption somewhere along the channel and the magic's not getting through, or the wings aren't formatted to be capable of using it right, or she just has an abnormally low amount of flight magic.

+Alex Lamsam 2:15 is where he talks about it

+Alex Lamsam were going off of what TheBronyNotion said about pegisi having magic so if they do then that's why scootaloo can't fly yet she doesn't have enough magic just like twilight she couldn't fly well because she had little magic since she just got her wings

It's not because she's not magical it's because wings need time to grow and her wings haven't grown strong enough to fly yet

+eevee time what magic do its all about the wings bro

+Graybuck what this teaching I'm not getting smarter I remember mlp being science class

she can fly when she's old enough I guess

Maybe you need magic to fly for Pegasus magic and maybe scootaloo doesn't have a lot of it


I think if this were to happen...won’t their skin color get in the boom too? Think about it, it can’t all just be there main and tail.


I guess watching this video is more interesting rather than understanding my science subject....


Well yeah twilight spell is color just the same but Rainbow Dash has also kind of the same colors so they might be related to the sonic rainbow


Maybe the rainbow aspect is generated from her cutiemark. Her mark is a rainbow lightning bolt after all. Plus, how would others know about the sonic rain boom if she is the only one who can do it? Maybe her element of loyalty is a part of this... thinking of it logically,  she is loyal to her speed which helped create the mark in the first place which is her element.

Temmie 11111 Magic is just science we don't understand.


I think that it just depends on the color of a ponies mane, and since ponies knew about the Sonic Rainboom before, somepony had to have pulled it off before...Rainbow's distant ansester? But that's just a theory! A Pony Theory!


The Brony Notion thinks that the little science lessons are a bit frustrating? Mix science and Magical science lessons together with one 9f my favorite shows equals a science + Magic lesson I will adore.


I used to think that the sonic rain boom colors would change if a different pony did it.<br>So if derpy did a sonic rainbow boom it would be a sonic blonde boom (idk lol 😂)

So if lightning dust have that magic boom thing will it be called “sonic lightboom”


yes yea the magic boom

also,  yes the color theory


And in the return of harmony: part 2, about 20 minutes in, the mane six creates a "rainboom" or "magic boom" and it's look almost exactly like a sonic rainboom.


Not to mention as well and idk if that episode was out yet but rainbows (dad i think) also has rainbow hair and the fact that other ponys know what it is and have seen it happen in the past but not recent enough that its a sort of myth/legend means that this could be something that one of her way earlier family memebers was rhe forst to ever discover. We know know that at least in the past two generations, being rainbow and her parents there was rainbow hair and fast flyers.


I think the rainboom was do the mane six could get there cutie mark at the time needed. Or the mane six (may or may have not) became, leading to no one protect equestria in its time of need.


it dose kinda make sence but then why is it called a "rainboom" if its not always a rainbow. the rainbow has its own very specific coulors so if the rainbooms coulor only really depened on the person causing it wouldnt that make it reduntant to name it after the rainbow, it could have just been called "magicboom" or "coulorboom"


@Karam Karam Games & Fun she COULD; its entirley possible if she flew fast enough but no one but RD had done it

Can fluttershy make a sonic rainboom not can fluttershy have a sonic rainboom

if he was flying fast enough or it could jut be rainbow dashes destiny to preform the sonic rainboom and bring her friends together

Theoretically, yes. I don’t see why, if she trained for long enough, she wouldn’t be able to create a similar effect.

Thrust SSC is faster...

BLOODHOUND LSR TO HIT 1000+MP/H IN 2021

I guess her trail would be butterfly themed. 🦋

I dont think because fluttershy flying so slowly?

Rainbow should be the only pony naturally to do a sonic rainboom. The reason for that is her colour palette. Imagine if another pegasus, such as Spitfire did it. Would the flame shape and the rainbow still be rainbow coloured or would it change to Spitfire's colour palette? Well, if it would adapt to Spitfire's colours, it wouldn't be a rainbow, and if it would stay rainbow colours, it wouldn't look as good. When Rainbow is flying seconds after the sonic rainboom has occurred, we can see that the rainbow is pretty much being drawn from her rainbow-coloured tail. So if a rainbow would be coming out of Spitfire's orangish-yellow tail, that wouldn't quite work. So Rainbow Dash was destined for this at birth, which might have something to do with genetics. Let me know what you think.<br>Also Fluttershy is overrated enough as it is, so no.

@Ayesha Zahra it doesnt matter what element she is, all she needs is speed

@Bluebelluwu if only it only the cute rainbow pegasus had

Its impossible,  she cant travel fast enough

Yes.
Any flying thing is capable of if
Even planes

CC IMMORTAL WITCH excluding how embarrassingly slow she flys, yes. I wouldn’t find it embarrassing but you get what I mean

Yes, but it is hard thinking of what the trail she would leave and what the sonic boom would look like.

@Princess Shelley She can work into it, but as of now she wouldn't try.

She can, but she wouldn't. She lacks the confidence and bravery to do it.

@Kakashi Hatake then lets make fluttershy so mad that she does it!!!!! XD

Wanted Hamster I’m pretty sure she meant a pegasus.

If your theory is correct shouldn’t it just be called a rainboom? Any Pegasus could move at the speed of sound if they tried hard enough.

Wanted Hamster “if a pony like RAINBOW DASH flys fast enough it creates a sonic RAINBOOM (Rainbow boom)”<br>They can make a rainboom if they have the same mane colors. But anypony Can do one like rainbow dash (just it wont be rainbow). Rainbow dash is just the only one who has proved the sonic color boom exists. So. Yea.

She might if she was brave enough but not likely since rainbows Been practicing all her life and even in the episode hurricane flutter shy she went the fastest she ever went before and still didn’t get close to the speed she needs

Of course not! It would scare the poor little animals.

ŸÚÏ ÍMMØŔŤÂŁ WITCH maybe if she fly fast enough

It wouldn't be a sonic rainboom, it would be like... a sonic whisper

And if my theory is correct, then no, bc it's only them with a rainbow mane and tail who can do it, bc RD's son can do it too bc he also have a rainbow mane and tail, and he is the only of RD's children, who have a rainbow mane and tail, and he is the only of the children, who can make a Sonic Rainboom

Romalaine Anne Bello she can but she cant fly fast but when she mad. .


Hmmm well here's how the pony color works

When the eyes go white the pony has its MAGIC gone wings,horns,etc

When the body color or mane goes gray or white it's there personality (that's mostly why twilight couldn't defeat discord in season 2 bc the ponies didn't have the personality traits they had so it didn't work)


I think the rainbow was caused by her tail. When she goes fast she has a rainbow trail. So the boom takes the trail with her.


I just...I just so impressed of the rainboom


I think Twilight color didnt fade (unlike her eyes) because she still had the friendship magic that IS her main magic thing and i think she is the "glue" in their friendship so it cant never really be taken away so thats why i think her colors didnt fade away unlike her eyes. I also think her eyes color DID fade because her magic. like ther reall magic not the friensdhip im talking about her horn and wings and the princess's magic only they got taken not her friendship magic because that is impossiable to take a connection between some ponies. (friends IS magic..and magic.IS magic?)

just to make a simple theory is that ponies (pinkie pie) say when ponies like RainbowDash are fast it causes the rainbow boom! and ponies in past episodes say it was just an old mares tale. So my theory is sence we dont know much about RainbowDash's parents we are able to say that there is just a small chance that the first ponies to create the rain boom could be from in RD. family. Am I right? please contact me to let me know what you think.


The sonic rainboom is Made out off,Highly fast force and energy And as the pony goes full speed The Colors of the pony exploded into the rainboom it releases energy form the force that The pony makes


The sound barrier broke and the boom that happend has spread out the clouds enough so that when the light came through the water it came out as a rainboom and not just a boom since she was in the sky in full daylight and

if you take some water and shine a lamp on it or something there will be a rainbow and clouds are white beacause if all of the colors are put tightly together it will be white, aaand,
I'll stop right here.


Horses (ponies) bones are WAY too heavy to fly(like us),birds can only fly because their bones are really light.I assume a Pegasus has really light bones too so if that is the case why can rarity fly? I think it is because unicorns is made to fly and has light bones this explains why it was so easy for twilight to fly when she turned into an alicorn tho if pinkie pie of aj got wings they would not be able to fly,dance they are normal ponies.


I think the color of the pegasus/alicorn's skin/mane/cutie mark changes the ‘rainbow’ because at Princess Twilight Sparkle II (i think), twilight did a sonic twi-boom which looked liked her cutie mark.


Now we know.. If Candence is a Pegasus then we know (kinda) How Pegasus magic work's.. Right?


I like to make a correction rainbow dash was not the first Pony to do the Sonic rainboom mainly because everyone knew about it before she did so clearly someone has to have it done it first so I think the founder of the wonderbolts did it but we may never know


55000 subs later and he is still our favorite changeling


1:08 aaaaaaannndd I officially love this guy


Since most times when the mane six use the elements of harmony it shows a RAINBOW. Shouldn't RAINBOW dash be the mane character out of the mane six? please do a video about this! Please and thank u.


Actually I think the first sonic rainboom was actually discovered by CELESTIA since when she sent luna to the moon it made a rainboom


I know that this video is old and all but I just wanted to know about when twilight had the power of all four alicorns, how did she not make a sonic rain boom, when flying. If she did how did other ponies especially tirek not notice it


if lightning dust pulled off a yellow one then it would be a rainboom but a golden or yellow boom


It is like I sharpened a very dull pencil when he changed his mouth shape :>


Then why didn’t that happen to Twilight in Twilight,s kingdom the color of her tail came but not the sonic rainboom
And why do they call it rainboom
I think that rainbows family might have done it.
It would make sense
