Beware, a little mistake has crept into my animations at 4:42. The light ray should not have been drawn as if it was "reflected" by the white hole. It should just have escaped from within the horizon. In fact, because it is an extension of a black hole's geometry, the white hole is still attractive, it draws things in, towards its center just like any other object. The difference is that nothing can ever reach its horizon. This is because the white hole is technically in "the past". So, because we can only travel towards the future, its impossible to go through it.
Based on my understanding, a black hole does not pull you in so hard that you can't get out of its event horizon, it removes the "out" geometrically so all directions take you to the singularity. similarly, a white hole removes the "in" curving all directions of space away from its singularity. so it's clear that there is no "reflection". the animations seem correct, the light travels through a straight line curved by the gravitational effect of the white hole.
@@thekid317 A white hole can be thought of as a black hole that happens to exist in a metric where time flows backwards. Since that particular worldline of light in the animation could not exist if the white hole were a black hole, it is cannot be the case with a white hole either. The correct scenario would be the light ray approaching the white hole's horizon. Correct me if im missing something
@@abstract_nonsense8683 I don't see that you're missing anything, but the thing is I highly disagree with the fact that the metric surrounding a white hole is reversing time, it is believed that a white hole does not push you out, it pulls you in exactly like a black hole and since time is running backwards the effect is played backwards too, but that's wrong because a black hole never pulls in at the first place, a black hole distorts spacetime so that all XYZ direction take you to its singularity. if a white hole is a black hole is a reversed time, it'll stay inescapable ad it'll look black, the real analogy is that a white hole distorts spacetime in a way that reveals time and all XYZ directions take you out. which means that a backwards time is not the cause of the lightpath, it's a consequence of the same effect behind the lightpath's bend, gravitations distortion
4:55 "We are able to stick it underneath our original hole" I dont want anything to stick underneath my hole... 😂😂
just wanted to point out that wormholes DEFINITELY WILL exert a huge amount of compression and/or decompression force on anything trying to enter/escape/cross it; because the liner momentum of the object's particles are along geodesics which converge and/or diverge by a huge degree. This might even give the travelers a nifty taste of some sweet sweet nuclear fusion and/or fission. Also might cause heat changes, melting/freezing the ship and the crew within. I highly doubt the human body, that evolved on the african savannas for hunting meaty animals, can survive such topological torments. :'( p.s. been a huge fan of this channel. love what u r doing.
"We didn't like the way the math initially told us the hole would form, so we made the math tell us another way"
That’s a very interesting thought, sometimes I wonder to what extent people have done this in other areas

This comment is somewhat beautiful. It's basically how science is being done (for better or worse).
Is this a critic, a comical portrayal of the science behind this concept, both or neither? I'm Legitimately curious

I don't understand how such a high quality video has so few views. This is excellent content, sir, truly! Edit: This comment was posted 8 months ago when the video only had a few thousand views. I'm glad to see that it has gained some of the attention that it deserves.
I wonder the same, he has made some very good ed videos and deserves atleast a million subs
It's due to the channel's relative youth. It's a translation to English of the original channel (with the same name) that is in French.
I also once commented the same....
Exactly
Well, the voice is kinda arrogant in the tone. It may repel some viewers.
If a wormhole couldn't bring us beyond it's time of creation, is it essentially a time checkpoint that human could travel back to at the end of the world
Except it was stated that one cannot travel 'to the past', which would have been a feature of the white hole should it have allowed travel.
@@epmcgee Agreed. What I got from this is that a wormhole connects 2 presents in different parts of space at the same time, unless you think of them as connecting different universes which may open the possibility of having the wormhole connect to a copy of this universe but in a different timeline or timeframe.
@@grggarro1 it's mentioned that time is also a dimension, and it mentions the function of the Einstein Rosen bridge where you move toward the future and not the past, hence travelling back through a white hole is impossible
@@epmcgee technically we can very easily time travel just go really fast(light speed) in space for a few years then come back and bam your time was like 20 years and theirs is like 20 years and a day!
@@grins9882 no
8:13 The fact that you're so close to a huge gravity generator ensures that, even if it only takes a few days to cross the wormhole, thousands of years have passed for everyone else.
This channel deserves more recognition for its quality

I am going through a period of depression these days, but your videos are so beautiful and stimulating they save my sanity by transporting me to a higher plane. Like looking at a starry sky (can't see many in London). Thank you.

Learning Quantum Mechanics is what saved me from part of my depressive state when I had an existential crisis around determinism!
I landed on this video while executing my 10 minutes daily random video views. 1) I am blown away by the quality of the video: script, science content, graphical representation and animations. 2) There's a perfect balance between advanced concepts and simple explanations, context and good use of examples. Super happy, discovered a pearl. Fairly certain that this channel will explode with millions of subscribers... Also, by reading the comments, I'm super happy that the viewers are also surprised by the video quality and channel content, meaning that we all have similar quality threshold Made my day!

Yup
No, leave that to kittens on Tiktok. This channel will grow much further, based on quality, but growth will be steady. In 10 years I might review this comment, if I'm spared :)
I love how spacetime is represented as a 3D fabric field rather than a 2D plane. It can be misleading to younger children to think that there is fixed direction in gravity.

Brilliant video, black holes, worm holes and time dilation are some things I could talk about for hours and not get bored of it, fascinating.
I like how you waited to near the end to drop the bomb that general relativity is not perfect.
Extremely good and clear explanations of very tough themes, really glad, that youtube showed me this channel.
I like how you always bring up the formulas for everything
Chill narration, great animation.
I think there is some misconception that gives a lot of people mistaken idea of mass = gravity (higgs = graviton) when saying because of it's mass it distort the space time around it ( 0:45 ) , from what I understood after searchig for Higgs - graviton differences, it's the energy not the mass distorting the space-time, photons that are massless can also have gravity fields around them. Also theoretically a blackhole from photons can exist. Correct me if I'm wrong but that what I came out after searching for higgs - graviton correlation
yeah thats right
What a content, even If one doesn't know a thing about laws of relativity, he/she can find interesting stuffs throughout the video. Excellent work, keep working on your good works.
Thanks a lot 🙏
Badass videos without even asking people to like or subscribe.. you know they will!
A truly superb work. Thank you.
I always find it fascinating that we as humans don't have our scientific curiosity as our number one priority, or else videos like this would be at a billion views.
Aside from other factors being mentioned in the video, if the space inside the wormhole is being stretched outwards from its center in order for it to exist in a valid/cross-able form, wouldn't that make, things that go through , possible to be ripped apart *depending* on the force needed to have it opened the first place and sustained?
Gawd I love your content :) Thanks for such bad-ass videos. Legitimately original man ... this is the first time I've ever even seen a video about wormhole geometry and whether or not they can feasibly be crossed. Really fxk'n interesting :)
This was really neat. Did you cover the other two types of wormholes displayed in this video ever?

Great video ScienceClic English and I like your videos so much :]
Another great video. Would love to see your treatment of potential shapes of the universe, since I've never been able to understand that, and I bet you'd do a great job. One side comment: you mention that quantum physics applies to microscopic stuff. It's funny people always say that, because electromagnetic waves can be the size of the Earth or bigger.
5:06 but would that be a whole or simply spacetime expanding everywhere equally? Kinda like what our universe does?

You seem to know exactly what I don't quite manage to understand from other videos and show exactly what I need to get it right.

When people start making up mathematical "possibilities" it ceases to be science and becomes wishful thinking. Still, it's interesting, and a fertile ground for science fiction.
If its mathematically possible but hasn't been observed or proven isn't it still science because its proven to be possible with the matj

Thanks ! Indeed, I explain it at the end of the video : a stable wormhole would require negative energy / mass to exist. Matter with a negative mass (exotic matter) is thought to be impossible though.

I had a dream about this happening once and the way to get through the hole is two make a black hole made of a positive energy source and a black hole made of antimatter. Then push them together and it almost instantly resets time in the region of space and the hole is distilled at a time that is not toward or backwards
Black holes are solid spheres of mass, not holes in ¨spacetime¨...
Yeah, it's pretty brazen how they manipulate folks' lack of understanding of the rubber sheet metaphor.
Black hole is not solid. It is just empty space with infinitely concentrated mass.
@@MEBVishwaS That´s a viewpoint not many physicists would agree with. When stars collapse into neutron stars, there[s still a super dense sphere there, it doesn´t magically disappear and it´s the same for the more dense black holes. No magic, just super dense spheres.
Neutron stars r solids cause they balance their gravitational force with the strong between neutrons. But black holes exceed that limit and became infinitely concentrated to zero dimensional point. It doesn't disappear but it is shrink to zero radius but it is there. If u fall into the black hole u won't hit it's surface cause it's not solid but u will be spagettified towards singularity. Physicist doesn't say it disappear but it is there, unreachable from our vision.
This guy doesn't even understand spacetime and quantom physics smh
An amazing video again!
This videos are insane, wow. Do you also have a video that talks about the "multiverse"? That would be amazing!!😍
"our universe"
Is this a critic on how we humans put a sort of possession label on the universe??? I kinda got confused there
In which case I think the video is correct, considering that there's the parallel universes theory going around, which also states that they might have different physics than ours. And given that the latter is necessary for explaining the video's subject, I think that there's no problem in saying "our universe" since this kind of precision might be necessary. Whereas with the possession thing, it might be inherent to some imprecision in modern English. That's my take on it.
Soviet Anthem plays
it was a joke and if you don't find it funny that's fine
I dont think that you wuld end up anywhere near a galaxy if you would exit (as radiation^^) a white whole...because it's a white whole xD Maybe it is because of that that they can not be seen - because light cant show it to es either...it bounces away in all directions, so there cant be light hitting us directly. The spot pointing directly at us would be infinite small. MAYBE...oof...this could be black matter. This is why it can not be detected...it pushes galaxies away from each other, because they can only exist between galaxies. They cant be detected, because spycetime is only pointing away from them. So even if you try to look at it, the light you see was bounced and comes from somewhere else... (like a good magigician - doesnt matter how hard you try to look where he exchanges cards, he always fools you to look somewhere else) I feel smart right now, but I am probably totally wrong xD
Indeed you are completely wrong. First of all that is not how we observe, the scattering of light would make an object more visible not less, a white hole would be ostensibly bright, brighter in fact than any other object in the universe. How you link a white hole to dark matter is beyond me, like what?? This is being a peak layman, linking two completely different things together. It's like saying a sandwich isn't as fast as a boeing 777. Doesn't make any sense. Dark matter doesn't push galaxies away, in fact the only property of dark matter we know is that it gravitationally 'binds' with other matter, so the opposite of pushing. Dark energy expands the universe and causes the increasing distance between distant galaxies.

@@ScienceClicEN 3:39
The idea here is that the topology of space can allow holes, but if you travel towards this hole it will always close in on itself, therefore these holes are impossible to "probe" (the topological censorship states that the topology of space : its "holes", are impossible to probe)
