ThoperSought also the reason we have 25 and 50 fps cameras and in the US they have 30 and 60 is pretty amazing. (It's about lighting)

I agree.

I agree. I’m guessing this is the reason car wheels on tv look like they are going backwards

It will also oscillate beacuse it is also in that space(here lycra) fabric:)

General Relativity necessitates 3 spatial and one temporal dimensions for the existence of gravitational waves.

I guess it's hard to do that with a suitable size since black holes are extremely heavy in comparisson to planets.

@@9WEAVER9 go ahead and make you 3 dimensional lycra tutorial then. For someone who is trying to sound intelligent you seem to miss the simplest understanding of what his intent with this video is. I wouldn't apply for any patent clerk jobs if I were you.

@@billcraig5614 bro i get it and people who seem to forget the fact that these are supposed to be simplified so as to be easily understood are annoying but more annoying are people who go around being incredibly rude on the internet for no good reason e.g. you

Real Engineering I support this statement in every way, shape or form! 🍄💋🍄💋

Gravity is the warping of space-time...the only thing your leaving out is that fact that it's 3-d.

Which fabric u used to in the above explanation

I’m going to be completely honest you this guy practical engineering The backyard scientist and maybe some others I don’t really know working on a single project would be the most glorious thing of RU-vid science seriously imagine a giant route Goldberg machine (i’m not sure if I typed it right or I got a completely wrong name but you know domino effect) just made from a bunch of chemical reactions complete mechanical genius and so many other things I don’t have time to name would be amazing seriously just imagine a humungous gas can popping starting up a clockwork on one side of a chemical process on the other and it just continues for like 25 m or so with pieces intentionally breaking for a glorious effect and the you (Aka real engineering) you could make a Animation oh what’s going on on the inside and practical engineering could also work as a secondary voice actor and if you ever do this please give me credit at least a small bit or something I just wanna see this you could have me in the background like a small piece of text or something but please do this it will be glorious bye

No

The observatory is closer to a very uneven cross.

@@Mernom yes but what they were testing were the oscillations observed where the two lasers meet in the intersection. So in terms of what ligo really cared about, the L is what's important.

YES or to draw a planet

@@official-obama fabric "is" space-time. L is alike the real shape of LIGO (nice!!!!) warping space-time causes distances in L to change. That's what they measured.

I said "draw a planet" but L - is a craaazy idea!

This is rad

Woah..

Zurri thank you

How? I didn't get that bit, could you please explain?

@@tusharjamwalIt takes energy to modify the shape of the fabric (pressing down again the "springiness" of the lycra)

When is this comment gonna published as a quote on the Ellen show!??

Take my upvote and leave

I'd like ur comment but I'd break the 69 likes, someone else can do that

Fuck yku

Lmao

That bit at the end was pure in joke gold :D

Twitchi ni

maciej53 thanks. Wanted to make sure that's what he meant. Even funnier if only a small group gets it.

Definitely takes some skill and thinking to be that resourceful. Great work, Steve!

I had already learned much about gravitational waves; loved the demonstration! But the details at the end is where I learned something new, thanks!

Same here. It was pretty clever.

What I took away from it is that faster-than-light travel is easy. You just tighten the fabric of your universe.

Funny that you mention that. If you were to "tighten" the fabric of your universe by stretching it out then you are actually also increasing the distance between point A and B on the fabric relative to this overhead view. Meaning it would take information the same amount of time to travel that distance even though it would appear to propagate faster overall. That is a great example of how relativity and the speed of light interact that I never thought of before reading this comment. Thanks for that! :)

Yeah if you like Smarter Everyday and Steve Mould you should look up Stuff Made Here, Practical Engineering, Jake Owen, Lesics, Animagraphs, and The B1M. I promise they won't disappoint!

By stretching the fabric of space :)

The main thing is that if you spin too slow the wavelength is too long so you can't see it and if it's too fast the fabric bunches up (and you have to match it to your camera!). Love your channel by the way!

+Steve Mould this is the best way I've seen for people to visualize and make sense of gravitational waves great job!

No wonder I haven't been seeing your posts Sally, for some reason I was no longer subscribed. I just guessed you were busy doing other things. Fixed!

@@SteveMould So is the bunching up of the fabric a way to visualize *why* the speed of light is a speed limit? Great video.

@@Ampersand100 interesting idea! I'll need to give that some thought.

If you can't beat the speed of light, just tighten the fabric of reality to your liking!

Yes.

Vihart, Yay!

FILTHY TAU BIRGIN < GENIUS PI CHAD

@@ncghost12 No

@@ultragamer4465 Tau is superior. Down with pi.

There a limit on the speed of likes.

+Samantha Usman amazing!

+Brandon Calvert thanks Brandon!

I think he probably did while he was using that drill, also i believe it would just create a much higher frequency waves (tho I'm not an expert and I haven't tried it)

I think it was uncalculated speed by drill may be faster

He will end up with a torn rubber sheet 😁

just guessing so take it with a grain of salt. the 'speed of light' in his universe was the wave propagation speed. so, if he exceeded it he would be out running the waves. so, either the sheet can't keep up and stuff starts to get tangled or something like a sonic boom happens. namely the wave starts to get "jump" discontinuities. he actually might have been going faster the wave front was quite a sharp drop.

Well you can already see the reflected waves returning from the edges causing harmonic distortions, if you continue to speed up the rotation of the drill, you will end up at a resonant frequency response to which you will begin to see the whole surface vibrating in a particular pattern...

+Chris Bovington thank you!

+mrbandishbhoir glad you could see past my deviant ways!

I don't understand people who dislike the τ just as I can't understand the people who dislike the π, the two work best together!

JellyGamer that's actually really interesting, never heard of that before

+tokfrans yes I did. Well spotted!

Three hundred million?

honestly it startled me

I came into the comment section to see if anyone else noticed lol

+Norbert Harrer thank you!

Not me lol it’s funny tho

+Daniel Escoz yes!

JeroenEch That is some really good imagination :) but traveling faster than light is a physical impossibility as far as Einstein confirmed. The main reason is that time is undefined if you're traveling at the speed of light. So the idea of traveling faster is a no-no. There's a video from vsauce explaining what we would "see" IF we traveled at the speed of light. Maybe you can check that out.

JeroenEch A photonic boom. As in "launch the photon torpedos Mr Sulu."

I think we saw that actually. If you'll notice sometimes the waves are really sharp, which I think is where the drill moves faster than the speed of sheet. The little casters start colliding with the waves themselves.

Cherenkov radiation is what happens if you go faster then light. Of course, it is because light travels slower inside a medium but hey, that is after all, a light equalivent of a sonic boom.

JeroenEch that actually does happen: www.iflscience.com/physics/ultrafast-camera-caught-light-doing-a-sonic-boom/ in the experiment however, they lowered the speed of light in a similar way to how light travels slower through glass than it does in a vacuum (this speed difference actually causes refraction you see in glass and water)

+Gilberto Urdaneta thanks!

Thanks! The bit at the end is just a stupid reference to the fact that most of my videos feature me ouring things out of a pot.

would they be tho? they are still rotating about an axis. wouldn't it be more cylindrical-ish?

Royvan7 No because they radiate equally in all directions

@@olbluelips ic thx

Yet, spiral

That was 3 dimensional, wasnt it? I mean the fabric is sort of a 2d plane. But the waves made the fabric raise above and below the plane into the 3rd dimension. Are you just saying the waves would be taller than his representation?

I think they are robots with a random bug in their algorithm.

sure, just deploy enormous laser interferometers and juggle some black holes in your ship :D

x.iso it doesn't really need to be black holes, it just needs to be sufficient weight being spun at sufficient speeds.

well if the source is nearby, then maybe something less than a neutron star would do.

well, it would not be very plausible as you would require enormous mass to make it work, and at monstrous speeds at that which in turn means even more mass as you need more gravity to hold the rotating objects together as they go faster (elsewise they'll reach escape velocity and so on). It's better to use light to measure distance and shapes where sound can not be used.

Great idea

or the large metal ball

Would that work with the stroboscopic effect?

@@nori8675 No

( ͡° ͜ʖ ͡°)

You do as well! Just really really gently

Yup!

Yep.

Here!

Yass

i'm still on the SED channel, just buffering this baby up :} cheers everyone!

+BoildownAH I'd like to know the answer to this too. Will do some research.

No, light slows down because it interacts with the atoms and molecules in a medium. Gravitational waves don't. The reason both have the same speed in vaccum is because the graviton, the hypothetical quantum particle of gravity is massless just like the photon

Light travels slower in air/water essentially because it interacts with the molecules and refracts. In a nutshell, the light travels at the same speed, but it travels further because it keeps needing to change direction as it bumps into things. Light always travels at the same speed, but water/air is like a bunch of obstacles that it has to go around. That makes the travel longer, hence why light seems to, at a human scale, travel slower in air/water.

The speed of light doesn't change in different materials. The speed of a light beam/light burst changes. Sane here, the sog doesn't change, but it gets distorted and deflected by the particles in the way. But light is slowed down because of something different!

Actually, while we're on the topic, I just *have* to link to this *great" video explaining that phenomenon: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-mICTVow3-3I.html

I tried searching it, but I think it's not up yet... This could be a kind of colaboration between the two.

It came out a couple years ago. watch?v=uzP8FFKpwQ0

kirkxyza Oh sorry... It had a different tumbnail than in this video... + I was expecting at least the word 'frame' in the title

***** Late comer?

God, that's what I was thinking! I really wanna know what it looks like!

I don't think there is an edge. But even if there was it would be such an incredibly weak signal, it would probably be buried in noise.

Damn right! Look how simple that equation was :)

there is no debate, just some misguided πeoπle.
