What if we could see Spacetime? An immersive experience 

I dunno what software you use to create these breathtaking renders, but this is phenomenal work

It is a masterpiece, the music, the animations, the content, it is a pleasure to learn from your hardworked videos.

I heard from some other channel there was a recent paper questioning whether real black holes had practical singularities. Does this visualization incorporate that paper?

Very nice visuals, also top notch music well done

Well worth the effort. Your channel is magical.

Glad you liked it 🙏

The bit where you show the straight line path of a satellite in orbit was excellent, I think this detail is so often misunderstood.

Yeah it's genuinely so good instead of just the same old flat disk everyone makes

I was like omg when i saw the disc 🙏

Yes. Usually they show the trampoline example but that’s just in one plane. This is in all directions, much more realistic visualisation

@@ggj1987 yeah the trampoline example is garbage because it fails to show motion of space. It rather suggests that space just bends and remains static. I think showing the trampoline to kids actually makes them dumber. At least don’t START with that analogy lol

​@@SlampthChompthyou're saying everything I came to the comments to say :)

​@@SlampthChompth yeah you've got people here in the comments arguing that space-time can't move therefore the animation is shit. The e only ever seen gravity explained on the sheet.

​@@ggj1987the trampoline always bothered me but I could never say why. I just knew intuitively it was a bad representation.

I don't wanna take away from the man but... I just don't see how anyone who knows relativity doesn't understand this. To animate it is a whole nother thing

highest peak of science fiction rather

​@asor8037 can't say something is something without some form of substantial evidence to dispute the current claim. Otherwise please take your ass back to school.

@@asor8037 adding rather, at the end of your sentence doesn't make you sound smart

@@HandTingSeason thanks for letting me know! The truth speaks for itself though, cartoons are not reality, and all we've ever seen is cartoons.

Why, it is here, for anyone interested

And I am a physicist and will be showing my class next week!!

Wow! I didn't know that theorical physicist existed!

Dear Alesandro Roussel, Octave Masson and JP Chatelain, Lyla. I work as a vacuum expert on the next generation gravitational wave detector, Einstein Telescope. A collaboration of over 1600 people at the moment of writing. If somehow you are not jet involved, you are very welcome to connect with us. I extent to you an invitation to come and visit my home institute: Nikhef in Amsterdam. I am sure there are many people interested in your animation and work, within the collaboration of the Einstein Telescope... My greatest compliments to all of you for your animation!

I heard Michelle Thaller describe it this way a few years ago. It was the first time I'd heard of spacetime described like that. This visual just made it that much more real.

Dialec is another You Tube site that portrays gravity as a river and has very good animation.

exactly y did it take so long for this form of visualization to be more common?

@@ratchethoe Because it's harder to do. A sheet is a 2D version of the same idea.

@@kurtwinslow2670 but Dialec doesn't understand acceleration.

Should be nominated for best nonsense animation of the religion of science.

@@kwimms what!?!? you out of mind!?

I think it deserves higher acclaim than that filth where academy awards are given to people who slap the host on the same night.

@@kwimms "the religion of science" You're projecting. Just because your religion is religious doesn't mean that science is also religious. Scientists don't hold ideas to be absolutely certain. We hold things to various degrees of probable certainty depending on the evidence for the claim. In the case of relativity, gravity, and spacetime, our current models are, as far as we know, the best and most accurate explanation of reality. Perhaps one day we will have to modify our understanding - that's the process of science. Science deniers often act as if every time something new is discovered, that the entire puzzle board is overturned. That's not what happens. Science is like a jigsaw puzzle where we're constantly finding and adding new pieces, and though we don't have it complete, we have a basic idea of how the final picture looks. Every now and then we realize one of the pieces we thought was in the right place actually didn't quite fit as perfectly as we thought, and in fact there's another piece that fits better. But none of this changes the overall puzzle. Once in a great while we may realize after putting in a particular new puzzle piece that it actually changes our conception of what the final image would look like - but that's rare (Einstein discovering relativity would be an example of that). But again - the overall puzzle (which represents humanity's great attempt at explaining the natural world) remains in progress. It's not a perfect process but it's literally the only method humanity has to discover and explain reality. I mean, it sure beats "such and such ancient book says..."

Yes, although I do wish for more/longer videos, I think ScienceClic has already earned its place as amongst the best of space RU-vidrs

@@DanielKRuiIt’s a no BS, down to the point channel, who’s team is incredibly well educated. At this point, it’s Quality, not quantity.

He is up there. These videos are bomb

Takes time to animate stuff and render stuff

​@@DeveloperJake It's made by one person

"Ce qui se conçoit bien s'énonce clairement et les mots pour le dire viennent aisément"

Thank you very much 🙏

@@ScienceClicEN Is there a album we can purchase to listen to these soundtracks without the narration ?

@@JcoleMc The album is freely available on my SoundCloud : soundcloud.com/aroussel/sets/voyage-a-travers-lespace-temps

Science?? 😂😂😂😂😂 It’s fukin cartoons you silly fool!!

Thanks a lot!

I've always found it hard to understand intuitively from those demos this is much better

This is my preferred explanation of gravity.. but it seems not the most popular. I have listened to dozens of talks on the subject and most describe space as statically stretched. The flowing of space makes SO much more sense.

@@brcfrmn01 Weird. I understand the sheet demos better personally. This is hard to imagine in your own head.

the sheet analog is perfectly fine for the Newtonian regime: depth -> potential -> time dilation (analogy->newton->weak field Einstein). it does lack a third dimension of space, tho...and that throws some ppl. idk, I think its a good start. In a rotating BH, there's more to worry about.

Thanks a lot 🙏

Yeah... this guy has bought the lie and brought it alive (a lie v). Stupendous achievement for a monkey!

IKR?????? He deserves a few million subs at least. This channel is truly so underrated, their videos are literally kurzgesagt levels of quality.

Thanks, glad you liked it!

Thank you so much 🙏

Yeah, that's the best way to visualise spacetime I've ever seen! He has a video introducing the model in a more detailed way, from a few years ago. What gives it even more weight is that it's physically accurate (the "river model" of spacetime).

Thanks!

And not only do the visuals, but also program the simulations that drive the visuals.

The grid accelerates less at the center, however it still has a faster speed than at the surface because it builds up momentum while falling. Another way to see it is that the gravitational potential energy is lowest at the center of the Earth, so in turn the kinetic energy must be highest there.

🙏

The problem I see is the 3D which suggestively says space is distorted and causes gravity. Gravitational attraction is mostly caused by distortions of the 4th dimension, time. I think without this distinction the animations can suffer from the same problem as the ball on a sheet model.

@@jeffroberts6865 this whole time I've been trying to understand what actually causes "gravity", and you're saying it's mostly distortions of time? Where can I hear more about that? every video I've looked up just says, space time bends = gravity but that doesn't sound like the whole story to me, and if it is, it sounds incomplete. At least it won't make any sense to me until it's explained what mechanism actually causes this

“These videos obviously take too much work to reasonably ask you to never quit making them” - He has a Patreon. A very reasonable way to ask, I believe. :)

@@stephjsinclair In that case, so is mine.
