It’s great! But, that’s not a picture of a black hole. That’s a plasmoid. And yes, there are thousands of them. Black holes are STILL just a theory, along with white ones. Sorry. Try again.
Also, it’s electro-dynamic forces, not gravity. It’s a plasmoid breaking down and neutrons escaping those forces and shooting out in vast jets. Black holes are ludicrous if you think about it. If nothing can escape a black hole, why would ANYTHING escape it. Everything is a fractal. So everything that is observed in space, can be recreated on Earth, on a smaller scale. Plasma cosmologists can observe plasmoids in the lab. You can’t make a black hole in a lab because they don’t exist, because The Big Bang didn’t happen.
I'm not a physicist, but the idea that the 'big bang' is the outflow of a black hole has been stuck in my head for years. The idea of matter/energy conversion taking place inside an event horizon; Hawking Radiation being an equivalent to gasses being expelled from the barrel of a gun (particles get sucked in, waste particles grt ejected; Honestly, I have never heard of cone theory but it makes perfect sense to me, and manages to put actual science terminology, and proven equations, to my wild spacetime theories.
i think a lot of people have that idea bouncing around, it just seems so satisfying. maybe in another life ill be able to do the math to make sense of it.. but not this one!

You aren't the only one that has thought a white hole is the opposite end of a black hole. I've often wondered if the 'Hawking radiation' of a white hole isn't actually what we call dark matter or dark energy. Since we can't figure out how to make a white hole 'exist' it could also possibly be why we can't figure out dark energy/matter.
The one thing that's always been left out of discussions of white holes-until now-has been any theory of how they might be created. Something we do have for black holes. That always made them seem less connected to reality for me. So thank you for including a proposed mechanism by which they might come into existence.

"discussions of white holes-until now" Odd, every 'scientific' discussion of white holes that I have seen has speculated on their origin, and usually says black holes . . . .
White holes are one of what are called "vacuum solutions" to General Relativity. They require the white hole to be empty space in an empty universe and to have always existed eternally forever in the past... for no "reason", spacetime is just curved like that. There's a vacuum black hole with identical requirements, and these two vacuum solutions are the same equation with the time coordinate flipped between positive and negative. Real, physically existing, black holes don't exist forever in a vacuum, because they form from collapsing supernovae. A real black hole is full of neutrons, and didn't exist some amount of time in the past. (Also probably has angular momentum, and electric charge.) Real black holes are messy.
Just finished The White Holes by Carlo Rovelli a week ago and now watched this awesome video which expanded on the topic even more and made some things clearer for me! Thank you for making such a great content, been watching Astrum for many years now and subscribed to Patreon today😄
Fantastic video as always, thank you ❤ Also, thank you for not burying the ad read in the middle, I don’t mind them, but having them as a trailer to the video is always preferable.
Beautifully done Alex! So glad I sat through the math which you kept accessible. Wormholes and white holes and parallel universes oh my! Yes, more please!
As someone who spends a good amount of the day exploring possibilities inside his ADHD brain, I screamed with joy at the end of the video when you spoke about the possibility that our universe might have begun from within a collapsing black hole. To me, the similarities between what existed before the big bang and what resides inside a black hole are so strikingly significant that I can't help but think they are the same thing.
This pre-primordial putative black hole, however, wouldn't have decayed in mass through emission of Hawking radiation -- would it? Following the theories here, I was puzzled where the energy that comes out of a putative white hole came from, if there's nothing but a Planck mass speck inside the black hole that preceded it. The story seems incomplete, or I'm not getting something.
You’ll love to learn about cosmic natural selection. Basically each new black hole changes the constants of the new universe slightly and thus it produces universe with many black holes- one like ours
Hi Alex! For the record, I prefer my gravity to be loopy rather than stringy. I wanted to say that this is BY FAR one of the best descriptions of black/while hole topography. The way you explained it completely makes sense of something borderline nonsensical. Keep up the terrific work!
Thank you for covering this. I remembered studying it and read that it was first theorized In 1964 and as a young 90s baby and growing up. By 2008 I was obsessed with the concept of having a black hole consume everything and asked myself "there has to be a place it's discharging or renewing/transferring the energy" and that's when I stumbled upon white holes and have been obsessed ever since lol now mid 30s still have a strong believe these white holes and black holes connect with each other and if possible of some type of quantum defragmenting we could send a prototype through it and hopefully it would reconstruct, if the laws permit. Love the channel! Always appreciate the work you put in. 🙏💪
The possibility of finding out what's going on in a black hole / white hole, honestly, can get me so excited that I can't sleep. And when I can't sleep, I try to reconcile every single PLAUSIBLE theory that has ever been suggested. It's insane to think we are staring at the answer to every equation in physics.
I ve been obsessed with this for over 20 years the universe us a white whole each black hole is like a seed to a new universe where new time and space is created through big bangs/ whiteholes
"asked myself "there has to be a place it's discharging or renewing/transferring the energy" " Yes. They draw in matter around them... and they evaporate. And that's not just some crazy hypothesis. That's what actually happens to Black Holes. Amazing, ain't it? You don't need a white hole to explain the mechanics of a Black Hole. White Holes, if they exist, (which they most likely do not) are not likely to be the same phenomena as a Black Hole. In fact, though they are often linked to Black Holes -- they are only equivalent in that they are based on many assumptions. While the average person is convinced that they must exist. Most physicists don't believe in them at all.
@@Unethical.FandubsGames I'm quite happy to dismiss the light whole theory. I just want to know where all that s*** that's getting sucked into the black hole goes to? If Hawking Radiation is the only byproduct of a black hole, then I want to know that process. I mean the sci-fi side of my brain would be super psyched to have some kind of white hole or alternate dimensional theory get proven. But ultimately solving the mystery would be the most satisfying thing of all, regardless of the answer. Even if it's disappointing 😅
Dude he is just semi-science literate and gets his "science facts" from skimming over other peoples space facts on science forums and such. Then he figures out some way to create controversy about it, and edits another space video recycling the same old random space footage. I can promise you... that if science would have confirmed the existance of "white holes", then THIS is not the first place you would have heard about it.
@@divat10 Uh.... Where is the hate? I know a great deal of things on this, and these are not facts. Have I stepped on your american dream or something?
@@captain_context9991 i am not american but ok. it may not be the the definition of hate but i have seen 3 comments of yours that is just discrediting the video's without an explanation exept for that this isn't proven jet. astrum is just explaining a theory. some people like theories instead of what we definitively know now. i understand that may be hard for you to understand but thats just it.
2:40 I love the idea that they are interconnected at a point of singularity. Forming an hourglass shape, which has even greater meaning. Considering that an hourglass is used to measure time. Time that can only flow in one direction. (Sounds similar to our most logical theories currently)
YES YES YES PLEASE do a video about the big bounce or big contraction!! I’m obsessed with watching videos that touch on that theory!! Maybe you’ve already done it since I’m 3 weeks behind in content, but that’s how excited I’ll be whenever I see you’ve made it!! I just listened to an hour and 20 minute lecture from Cambridge University Astronomy’s TH-cam channel called “Echoes of the Big Bang - Probing the beginnings of the cosmos” or something very similar. It was absolutely fascinating, though, I admit a bit went over my head. But that’s ok, I think I’m absorbing 85% of the content of that talk. I don’t have my HS diploma. I’m AuDHD as they call it, or, I have Autism Spectrum Disorder and ADHD. I am a late diagnosed female(just a couple of months ago at 44) and I fell through the cracks in school, and through the healthcare system(though protocols were *much* different when I was a kid), so I made it to half way through junior year because of the anxiety that went with it. I don’t have any self confidence, though I’ve been told I have a high IQ. I’m scared to take the GED test and get my HS equivalency. I’ve built it up to be this huge thing. It’s gotten in the way to progress for me. Is 85% good, or would I understand more if I had finished the last two semesters of HS? I often think about what it would be like to go to college and get some kind of space science degree. I’m good at math. I adore science. Anyway, I love hearing anyone talk about cyclical universe theory/the big contraction/loop quantum theory/the big bounce!! Do eeeeet! 😁😂
As far as I know, when I took my GED, each subject had a total score of 800, and I needed 440 to pass. So long as you can read well, the only subject that could give you trouble would be the math. Refresh on high school math if that's a weak spot for you, and you should be just fine. Most of the other sections, like the science part, provide all the information you need to answer, so long as your reading comprehension is good. Judging by your writing, you'll be fine! And you can always try it again, if necessary. There might be a wait period for a retest but you wouldn't be banned from trying again.
As fascinating and beautifully presented as always. PLEASE do give us the follow up to this video. I need to watch this one again, stopping to internalise each piece of new information or new idea. There are some really mind-expanding ideas that can be generated.
As long as we insist on cars and roads we insist on construction and traffic cones. More cars, more roads, more cones. Rail, however, can be fixed without any problem for you, and it lasts damn near forever.
Very well done presentation! That was pretty profound. The diagram you showed is known as the infinite knot. And surprisingly this symbol has been used as far back as the 14th century! They seemed to know of the multiverse even then and used the infinite knot symbol as the representation of it.
Hey I really like your profile picture and if you let me, I would make such an amazing mural out of it! If you don’t mind one of your post could be my inspiring muse for an art project i’m working on for a client. You will totally get paid for it as well as a bonus also get credits.
I was told there'd be no math. 😄 This is so far over my head, I am unable to express my ignorance of the subject. I bow to the people who can hold an intelligent discourse of the subject matter. 😵💫
This is a concept that really interests me. For years I've thought about the idea that our universe could be the rememnants of a dead blackhole, or at least a blackhole that has lost enough mass through hawking radiation, that it can no longer sustain itself, releasing all of that potential energy and condensed matter in a a sort of a big bang. To take it a step further, blackholes could be universes in the making and that could explain the nature of parallel universes. It doesn't necessarily mean that a universe would be born within a universe from a white, due to the fact that the curvature of spacetime is so intense inside a black hole, that it could very well be flung into whatever fabric lays outside of our universe. Considering the time dilation, the creation of a new universe's coordinates could even be a point in time in the very far distant future. Awesome video, love this channel.
Well, Alex covered the Kerr-Penrose curfuffle very eloquently. Nice graphic to boot.👌 I wonder if the quasar SS 433’s particle acceleration so many light years away from it could possibly be quantum entangled in any way or if it is just the particles from its partner Star. Just curious.
"The Builders of Roads" used a network of black holes to travel the universe. At least in the Perryverse. Nice to see decades old sci-fi see a revival.
I love this channel and others like it so much. I really love astronomy, but I cannot have it as a career due to a learning disability. Channels like this help me learn about astronomy in a way I can understand, which I greatly appreciate!
Commenting before I watch the whole video; if white holes are the opposite of black holes, which possess crushing levels of gravity, would a white hole be the opposite, areas of antigravity, or places where space actively pushes or repulses matter and light?
Idk about anti-gravity, they should repel matter/light in some way. Which is why I’ve always wondered if there’s a connection between dark energy and white holes.

Imagine recording a video of a black hole, then play that video backwards and what you see is a white hole. They're not physically possible because the "white hole" is one of several "vacuum solutions" to general relativity which require empty space in an empty universe, and spacetime has been curved in this particular way eternally forever in the past for no reason. Physically real black holes are messy, forming from collapsing supernovae or neutron star collisions... And 1. Having stuff inside of them 2. Having a begining in the finite past, not existing before stars.
I'm not sure about anti-gravity but if they exist as the end form of a black hole they likely have immense gravity that decays over time and with nothing able to enter I imagine it to be like a star where it's a giant ball of mass slowly growing until it stops. How this mass would become a whole universe would be an entirely new problem to solve
I don’t know why but the idea of the white holes excites me to my core! And the fact that Big Bang could’ve potentially been a white hole just gives me chills. This video is everything i ever needed so now i can show my friends why this topic has so much of my interest😁 Would love to see more!

As a photographer there's a time principal that any object can become "washed out" over too much time. If a black hole was observed over the duration of its existence, the collective Hawking radiation could technically be considered a white hole... when viewed along the "T" axis it would be a continuous emission of information until it is exhausted.
Perhaps white holes are simply the dark matter of other universes. The inverse of the inexorable collapse of the black hole becomes the inexorable expansion of the other. Becoming an infinite string of recursive collapse and expansion...

Oh YES! More about the big bounce/white hole idea, it sounds like such a relief from all the black hole destruction and universe expansion death ideas.
glad you did a vid on this. me and a friend wrote a paper on this subject a few years ago and its neat to see this idea getting around The paper focused more on the nature of the black holes interiors and logically refuted that relativity and conservation of energy would still exist within the event horizon. but what was really interesting was that the idea was later tested in a simulation. and it was found that relativity could work with a theoretical threshold. if the threshold was reached. it would reset. creating a pocket of spacetime that would expand faster then the speed of light so nothing can reach the edge. relative expansion and contraction of space occurs naturally with time dilation, what we see as the size of the black hole means nothing to how big the interior can be. the most interesting thing about this was the interior of this simulated black hole, ended up looking alot like what we thought the universe would look like at the big bang, where time bearly existed and thousand of lightyears of volume were created in what to us looked like a 10th of a second. which leads to a interesting and scary idea. what if our big bang was just another universes black hole, and were still in it.
Your final thought is what I believe the cosmological event horizon is. I think the "observable" universe is just that; the interior of a large black hole.

This is a fascinating subject, well presented and beautifully explained, as usual. It's highly likely that the physics us mere humans have concocted, in the very short time we've existed, to explain what we see around us is entirely wrong. And it's also likely that the parts we have correct are dismally incomplete. But that's what's so exciting about it all...since nobody can profess to know the answer to anything, there's always space for conjecture. And, in that, our understanding can evolve, much as we ourselves have evolved. Keep it up Alex - you are doing a sterling job indeed 👍
Just so I can dumb it down for myself... there are only THREE things we can see from a black hole are: The singularity; the event horizon; and our perspective, BUT the fourth phase could be a parallel universe?
Gotta feel good knowing you inspired a 15m+ YT channel to expound on this idea with actual animations of what it would look like for the observer to fall into a spinning black hole 🤘🏻
In my religion, we live in a white hole. And every black hole is a white hole, just seen from different angles. But we'll never find white holes, because we're on the wrong side to see it. We only see black holes. My religion is inspired in Black Hole Cosmology, and since it's mine, I believe in whatever I want.
Oh, and in my religion, the background heat/noise is new matter entering our universe (i.e. matter being absorbed by a black hole in our "upper" universe, where we can't ever reach).
It does because if you would kill yourself in the past you won't exist in the future, but you are in the future which means you did not kill yourself in the past
The very first time I ever heard the term "wormhole" was in 1979 from the scene in the first "Star Trek" film. It was a unknown and scary concept to me which I didn't comprehend. The first time I heard the term "Black Hole" was in the mid to late 1970's from the "Space: 199 episode, "Black Sun" (my favorite of the series along with the episode where aliens give the moon a temporary Earth-like atmosphere).
I've long thought that the general cycle was pure energy in singularity, bang, entropy increases until only pure cold matter exists, at which point there will be nothing to counter gravity, it will all want to congeal, the big collapse begins, compressing it all again to the point the energy soup reforms into another singularity, and we do it all over again. This lines up great with that.
Somehow I always thought that the big bang was a white hole connected to a black hole in a parallel universe. Sounds good to know that my hunch may actually be a real thing. Black holes, wormholes and white holes were dramatized at the end of the movie Interstellar. Cooper travels through the inner horizon and escapes through a white hole although thats not explicitly stated in the movie. I never bought it but still it's kinda cool !!
A very interesting book about this subject matter is "Black holes, the key to understanding the universe" by Brian Cox and Jeff Forshaw. Just throwing it out there for people who are interested
The big bounce theory is something that I have convinced myself is the only logical explanation of the “start” of the universe. We will never be able to see past a certain point due to the fact that as we peer further back in time we will run into the white hole. The extended Penrose diagram is a representation of the life cycle of the universe. I would love an in depth look into this and will be looking more into the loop quantum gravity! Great video❤
I think it's good to remember that the "laws of physics" are really just a current best fit model. A human way of conceptualising so that we can make useful predictions, it would be quite grandiose to assume that our models and concepts like mathematics are in fact laws governing the universe. The universe is not really governed by mathematics - the equations we use to model the universe are governed by mathematics, a human construct. When we talk about spacetime being curved or black holes having a particular geometry, we are using mathematical concepts as metaphors to help visualise and reason about the phenomena - this is wonderful for making accurate predictions, but one has to be careful not to reify the metaphor i.e use mathematical extrapolations as evidence. A prediction of an impossible object is probably more likely to be evidence of a flaw in our model, than the existence of the impossible object.
Okay... so... right about 6:44 the statement is made that, essentially light from region 1 (our universe) cannot travel to region 3 (a parallel universe), but... If light goes into a black hole... and eventually spills outwards through a white hole - LONG time though it may be... isn't the light travelling between regions. (And, as I understand it, light doesn't "experience" time so...) Therefore, can't light just sort of burrow serpentine through the universes?

I never considered an explanation like this to the quantum paradox. I figured it was one of those things humanity was unable to process correctly. Or it may, might be this explanation. I have often thought this material could seed spacetime without detonation, being not especially in contact with normal matter. Thinking of antimatter somehow places it in Saudi-Arabia, but that would just be my internal gears missing a shift.
This is the key along with light having non zero mass that will lead to a unified theory of everything. It will also explain 'spooky action at a distance '.
I know its all vast time scales but ive always felt that the universe only being 14 billion years old always felt kinda. . . short. So the idea that the universe is a whitehole from an older sounds interesting.
I like the idea that it’s possible that information arranges itself in a specific way in black holes. So in the event that the universe all ends up in 1 black hole right before it ends the black hole will explode into a white hole with all info arranged in the same way it was last time. So with no factorial differences in the event, it will play out the exact same. The universe will loop😂
So something that’s always bothered me is technically you can’t touch/ go through a black hole. As you get closer to the event horizon, space time warps around you which slows you down/ alters how time moves around you. Right before you touch the event horizon, you’d be moving so slow it would take an infinite amount of time to move a single Planck length. Theoretically, you can’t cross the event horizon, thus you can’t cross over the EH You can only come right next to it, but never through it. Am I correct on this?
your perspective does not change. they appear to stop, to a outside observer, as time slows. it may take 10,000 years for you to actually pass threw by the observer frame of time. The one falling in would see 10,000 years flash by in a few minutes as the universe brightened and crunched down behind them into a dimming fish eye lense perspective. blackness would envelope most of the space around them (from light only being able to reach you from the path you enter) and then they would know they had passed the event horizon.
The event horizon of a black hole is not a physical thing (it's empty space), it's a coordinate singularity for a _distant_ observer at a constant radius from the black hole's center of mass. If you switch to using a coordinate system based on the proper time of an observer in free-fall (like Gullstrand-Painleve) nothing happens to them at the location where a distant observer sees an event horizon. The falling coordinate system is continuous all the way to the physical singularity at the black hole's center of mass.
So curious! I kept posting on TH-cam videos in 2011 & 2012 about how I thought it made more sense that black holes would eventually rebound into white holes. I wonder when the new theory was introduced.
You made my day when you talked about the big bounce. I had that idea before but never heard it before from anyone else. Also, it feels good to give it a name. Sadly if our universe is expanding, that means the other is compacting. RIP our sister universe.
The first time I saw a white hole exploding I was in my teens. Time slowed down for me at that moment. Gravity seemed heavier just after. For sure it was an event horizon.

But, that’s not a picture of a black hole. That’s a plasmoid. And yes, there are thousands of them. Black holes are STILL just a theory, along with white ones. Sorry. Try again.
Also, it’s electro-dynamic forces, not gravity. It’s a plasmoid breaking down and neutrons escaping those forces and shooting out in vast jets. Black holes are ludicrous if you think about it. If nothing can escape a black hole, why would ANYTHING escape it. Everything is a fractal. So everything that is observed in space, can be recreated on Earth, on a smaller scale. Plasma cosmologists can observe plasmoids in the lab. You can’t make a black hole in a lab because they don’t exist, because The Big Bang didn’t happen.
I'm not a physicist, but the idea that the 'big bang' is the outflow of a black hole has been stuck in my head for years.

You aren't the only one that has thought a white hole is the opposite end of a black hole. I've often wondered if the 'Hawking radiation' of a white hole isn't actually what we call dark matter or dark energy. Since we can't figure out how to make a white hole 'exist' it could also possibly be why we can't figure out dark energy/matter.
The one thing that's always been left out of discussions of white holes-until now-has been any theory of how they might be created. Something we do have for black holes. That always made them seem less connected to reality for me. So thank you for including a proposed mechanism by which they might come into existence.

"discussions of white holes-until now" Odd, every 'scientific' discussion of white holes that I have seen has speculated on their origin, and usually says black holes . . . .
White holes are one of what are called "vacuum solutions" to General Relativity. They require the white hole to be empty space in an empty universe and to have always existed eternally forever in the past... for no "reason", spacetime is just curved like that. There's a vacuum black hole with identical requirements, and these two vacuum solutions are the same equation with the time coordinate flipped between positive and negative.
Real, physically existing, black holes don't exist forever in a vacuum, because they form from collapsing supernovae. A real black hole is full of neutrons, and didn't exist some amount of time in the past. (Also probably has angular momentum, and electric charge.) Real black holes are messy.
The best way you can learn EN is watching things that you really like. Thank you very much!
Just finished The White Holes by Carlo Rovelli a week ago and now watched this awesome video which expanded on the topic even more and made some things clearer for me! Thank you for making such a great content, been watching Astrum for many years now and subscribed to Patreon today😄
Fantastic video as always, thank you ❤ Also, thank you for not burying the ad read in the middle, I don’t mind them, but having them as a trailer to the video is always preferable.

Beautifully done Alex! So glad I sat through the math which you kept accessible. Wormholes and white holes and parallel universes oh my! Yes, more please!
Hello 👋
Cool
As someone who spends a good amount of the day exploring possibilities inside his ADHD brain, I screamed with joy at the end of the video when you spoke about the possibility that our universe might have begun from within a collapsing black hole. To me, the similarities between what existed before the big bang and what resides inside a black hole are so strikingly significant that I can't help but think they are the same thing.
I just suddenly started thinking of this also halfway through.. the more we kinda learn the more we realize we dont understand
This pre-primordial putative black hole, however, wouldn't have decayed in mass through emission of Hawking radiation -- would it? Following the theories here, I was puzzled where the energy that comes out of a putative white hole came from, if there's nothing but a Planck mass speck inside the black hole that preceded it. The story seems incomplete, or I'm not getting something.
The big bang happened at every location in space. Black/White holes happen at only one single location in space.
You’ll love to learn about cosmic natural selection. Basically each new black hole changes the constants of the new universe slightly and thus it produces universe with many black holes- one like ours
@@sprightlyrandom1550 What? That makes no logical sense and it's not even a theory.
Hi Alex! For the record, I prefer my gravity to be loopy rather than stringy. I wanted to say that this is BY FAR one of the best descriptions of black/while hole topography. The way you explained it completely makes sense of something borderline nonsensical. Keep up the terrific work!
Keep 'em coming Astrum!!! Great stuff, as always!! Fascinating, thought-provoking videos!!!!
i've been watching your videos for a while, but it was THIS video that convinced me to subscribe
That was a fascinating topic/theory. I'd love to hear more.
Thank you for covering this. I remembered studying it and read that it was first theorized In 1964 and as a young 90s baby and growing up. By 2008 I was obsessed with the concept of having a black hole consume everything and asked myself "there has to be a place it's discharging or renewing/transferring the energy" and that's when I stumbled upon white holes and have been obsessed ever since lol now mid 30s still have a strong believe these white holes and black holes connect with each other and if possible of some type of quantum defragmenting we could send a prototype through it and hopefully it would reconstruct, if the laws permit. Love the channel! Always appreciate the work you put in. 🙏💪
The possibility of finding out what's going on in a black hole / white hole, honestly, can get me so excited that I can't sleep. And when I can't sleep, I try to reconcile every single PLAUSIBLE theory that has ever been suggested.
It's insane to think we are staring at the answer to every equation in physics.
I ve been obsessed with this for over 20 years the universe us a white whole each black hole is like a seed to a new universe where new time and space is created through big bangs/ whiteholes
"asked myself "there has to be a place it's discharging or renewing/transferring the energy" "
Yes. They draw in matter around them... and they evaporate. And that's not just some crazy hypothesis. That's what actually happens to Black Holes. Amazing, ain't it? You don't need a white hole to explain the mechanics of a Black Hole.
White Holes, if they exist, (which they most likely do not) are not likely to be the same phenomena as a Black Hole. In fact, though they are often linked to Black Holes -- they are only equivalent in that they are based on many assumptions. While the average person is convinced that they must exist. Most physicists don't believe in them at all.
@@Unethical.FandubsGames I'm quite happy to dismiss the light whole theory. I just want to know where all that s*** that's getting sucked into the black hole goes to? If Hawking Radiation is the only byproduct of a black hole, then I want to know that process.
I mean the sci-fi side of my brain would be super psyched to have some kind of white hole or alternate dimensional theory get proven. But ultimately solving the mystery would be the most satisfying thing of all, regardless of the answer. Even if it's disappointing 😅

Yes make that video please, I can’t wait to watch it already. 😊
YES YES YES PLEASE do a video about the big bounce or big contraction!! I’m obsessed with watching videos that touch on that theory!! Maybe you’ve already done it since I’m 3 weeks behind in content, but that’s how excited I’ll be whenever I see you’ve made it!!
I just listened to an hour and 20 minute lecture from Cambridge University Astronomy’s TH-cam channel called “Echoes of the Big Bang - Probing the beginnings of the cosmos” or something very similar. It was absolutely fascinating, though, I admit a bit went over my head. But that’s ok, I think I’m absorbing 85% of the content of that talk.
I don’t have my HS diploma. I’m AuDHD as they call it, or, I have Autism Spectrum Disorder and ADHD. I am a late diagnosed female(just a couple of months ago at 44) and I fell through the cracks in school, and through the healthcare system(though protocols were *much* different when I was a kid), so I made it to half way through junior year because of the anxiety that went with it.
I don’t have any self confidence, though I’ve been told I have a high IQ. I’m scared to take the GED test and get my HS equivalency. I’ve built it up to be this huge thing. It’s gotten in the way to progress for me. Is 85% good, or would I understand more if I had finished the last two semesters of HS?
I often think about what it would be like to go to college and get some kind of space science degree. I’m good at math. I adore science.
Anyway, I love hearing anyone talk about cyclical universe theory/the big contraction/loop quantum theory/the big bounce!! Do eeeeet! 😁😂
As far as I know, when I took my GED, each subject had a total score of 800, and I needed 440 to pass. So long as you can read well, the only subject that could give you trouble would be the math. Refresh on high school math if that's a weak spot for you, and you should be just fine. Most of the other sections, like the science part, provide all the information you need to answer, so long as your reading comprehension is good.
Judging by your writing, you'll be fine! And you can always try it again, if necessary. There might be a wait period for a retest but you wouldn't be banned from trying again.

This is a concept that really interests me. For years I've thought about the idea that our universe could be the rememnants of a dead blackhole, or at least a blackhole that has lost enough mass through hawking radiation, that it can no longer sustain itself, releasing all of that potential energy and condensed matter in a a sort of a big bang. To take it a step further, blackholes could be universes in the making and that could explain the nature of parallel universes. It doesn't necessarily mean that a universe would be born within a universe from a white, due to the fact that the curvature of spacetime is so intense inside a black hole, that it could very well be flung into whatever fabric lays outside of our universe. Considering the time dilation, the creation of a new universe's coordinates could even be a point in time in the very far distant future. Awesome video, love this channel.

Commenting before I watch the whole video; if white holes are the opposite of black holes, which possess crushing levels of gravity, would a white hole be the opposite, areas of antigravity, or places where space actively pushes or repulses matter and light?
Idk about anti-gravity, they should repel matter/light in some way. Which is why I’ve always wondered if there’s a connection between dark energy and white holes.

Imagine recording a video of a black hole, then play that video backwards and what you see is a white hole. They're not physically possible because the "white hole" is one of several "vacuum solutions" to general relativity which require empty space in an empty universe, and spacetime has been curved in this particular way eternally forever in the past for no reason.
Physically real black holes are messy, forming from collapsing supernovae or neutron star collisions... And 1. Having stuff inside of them 2. Having a begining in the finite past, not existing before stars.
I'm not sure about anti-gravity but if they exist as the end form of a black hole they likely have immense gravity that decays over time and with nothing able to enter I imagine it to be like a star where it's a giant ball of mass slowly growing until it stops. How this mass would become a whole universe would be an entirely new problem to solve
What if the white holes are the dark energy? That expands the universe?

As a photographer there's a time principal that any object can become "washed out" over too much time. If a black hole was observed over the duration of its existence, the collective Hawking radiation could technically be considered a white hole... when viewed along the "T" axis it would be a continuous emission of information until it is exhausted.
Perhaps white holes are simply the dark matter of other universes. The inverse of the inexorable collapse of the black hole becomes the inexorable expansion of the other. Becoming an infinite string of recursive collapse and expansion...

Cat: So what is it?!
I was hoping Dwarfer's were still around, thank you internet
glad you did a vid on this. me and a friend wrote a paper on this subject a few years ago and its neat to see this idea getting around
The paper focused more on the nature of the black holes interiors and logically refuted that relativity and conservation of energy would still exist within the event horizon.
but what was really interesting was that the idea was later tested in a simulation. and it was found that relativity could work with a theoretical threshold.
if the threshold was reached. it would reset. creating a pocket of spacetime that would expand faster then the speed of light so nothing can reach the edge.
relative expansion and contraction of space occurs naturally with time dilation, what we see as the size of the black hole means nothing to how big the interior can be.
the most interesting thing about this was the interior of this simulated black hole, ended up looking alot like what we thought the universe would look like at the big bang, where time bearly existed and thousand of lightyears of volume were created in what to us looked like a 10th of a second. which leads to a interesting and scary idea.
what if our big bang was just another universes black hole, and were still in it.
Your final thought is what I believe the cosmological event horizon is. I think the "observable" universe is just that; the interior of a large black hole.
this is so perfect to watch for advanced space docu watchers like me xD i love these real ideas so much to daydream about.

This is a fascinating subject, well presented and beautifully explained, as usual.
It's highly likely that the physics us mere humans have concocted, in the very short time we've existed, to explain what we see around us is entirely wrong. And it's also likely that the parts we have correct are dismally incomplete. But that's what's so exciting about it all...since nobody can profess to know the answer to anything, there's always space for conjecture. And, in that, our understanding can evolve, much as we ourselves have evolved.
Keep it up Alex - you are doing a sterling job indeed 👍

The very first time I ever heard the term "wormhole" was in 1979 from the scene in the first "Star Trek" film. It was a unknown and scary concept to me which I didn't comprehend.
The first time I heard the term "Black Hole" was in the mid to late 1970's from the "Space: 199 episode, "Black Sun" (my favorite of the series along with the episode where aliens give the moon a temporary Earth-like atmosphere).
I've long thought that the general cycle was pure energy in singularity, bang, entropy increases until only pure cold matter exists, at which point there will be nothing to counter gravity, it will all want to congeal, the big collapse begins, compressing it all again to the point the energy soup reforms into another singularity, and we do it all over again. This lines up great with that.

Somehow I always thought that the big bang was a white hole connected to a black hole in a parallel universe. Sounds good to know that my hunch may actually be a real thing.
Black holes, wormholes and white holes were dramatized at the end of the movie Interstellar. Cooper travels through the inner horizon and escapes through a white hole although thats not explicitly stated in the movie. I never bought it but still it's kinda cool !!

Please follow up with a deeper dive on the singularity... I always thought it was the same as the event horizon, now I'm confused
I would absolutely love to hear about the big bounce theory!! Thats so cool, omg
i remember a video from action lab showing how a white hole would act. Kinda explains why spacetime is expanding at an accelerated rate, doesn't it?
The big bounce theory is something that I have convinced myself is the only logical explanation of the “start” of the universe. We will never be able to see past a certain point due to the fact that as we peer further back in time we will run into the white hole. The extended Penrose diagram is a representation of the life cycle of the universe.
I would love an in depth look into this and will be looking more into the loop quantum gravity! Great video❤
I think it's good to remember that the "laws of physics" are really just a current best fit model. A human way of conceptualising so that we can make useful predictions, it would be quite grandiose to assume that our models and concepts like mathematics are in fact laws governing the universe. The universe is not really governed by mathematics - the equations we use to model the universe are governed by mathematics, a human construct. When we talk about spacetime being curved or black holes having a particular geometry, we are using mathematical concepts as metaphors to help visualise and reason about the phenomena - this is wonderful for making accurate predictions, but one has to be careful not to reify the metaphor i.e use mathematical extrapolations as evidence. A prediction of an impossible object is probably more likely to be evidence of a flaw in our model, than the existence of the impossible object.
I was introduced to white holes through Diane Duane's "So You Want to be a Wizard". Fred was a g 😔✊
The diagram didn't help my brain comprehend it even a little 😂
Okay... so... right about 6:44 the statement is made that, essentially light from region 1 (our universe) cannot travel to region 3 (a parallel universe), but...
If light goes into a black hole... and eventually spills outwards through a white hole - LONG time though it may be... isn't the light travelling between regions. (And, as I understand it, light doesn't "experience" time so...)
Therefore, can't light just sort of burrow serpentine through the universes?

I never considered an explanation like this to the quantum paradox. I figured it was one of those things humanity was unable to process correctly. Or it may, might be this explanation. I have often thought this material could seed spacetime without detonation, being not especially in contact with normal matter. Thinking of antimatter somehow places it in Saudi-Arabia, but that would just be my internal gears missing a shift.
This is the key along with light having non zero mass that will lead to a unified theory of everything. It will also explain 'spooky action at a distance '.

If you could enter a black hole and then move back out of it FTL; would you arrive many years in the future?
I know its all vast time scales but ive always felt that the universe only being 14 billion years old always felt kinda. . . short. So the idea that the universe is a whitehole from an older sounds interesting.
Hello 👋
I like the idea that it’s possible that information arranges itself in a specific way in black holes. So in the event that the universe all ends up in 1 black hole right before it ends the black hole will explode into a white hole with all info arranged in the same way it was last time.
So with no factorial differences in the event, it will play out the exact same. The universe will loop😂
This is by far my most favorite channel on youtube. Unreal content. Thank you, Alex.
the music at around 6.00 reminds me of the track by Vapourspace - Gravitational Arch Of Ten (1993)
Hello 👋
So something that’s always bothered me is technically you can’t touch/ go through a black hole. As you get closer to the event horizon, space time warps around you which slows you down/ alters how time moves around you. Right before you touch the event horizon, you’d be moving so slow it would take an infinite amount of time to move a single Planck length.
Theoretically, you can’t cross the event horizon, thus you can’t cross over the EH
You can only come right next to it, but never through it.
Am I correct on this?
your perspective does not change. they appear to stop, to a outside observer, as time slows.
it may take 10,000 years for you to actually pass threw by the observer frame of time. The one falling in would see 10,000 years flash by in a few minutes as the universe brightened and crunched down behind them into a dimming fish eye lense perspective. blackness would envelope most of the space around them (from light only being able to reach you from the path you enter) and then they would know they had passed the event horizon.
The event horizon of a black hole is not a physical thing (it's empty space), it's a coordinate singularity for a _distant_ observer at a constant radius from the black hole's center of mass. If you switch to using a coordinate system based on the proper time of an observer in free-fall (like Gullstrand-Painleve) nothing happens to them at the location where a distant observer sees an event horizon. The falling coordinate system is continuous all the way to the physical singularity at the black hole's center of mass.
Well done. Compelling stuff!
do The BIG Bounce.
So curious! I kept posting on TH-cam videos in 2011 & 2012 about how I thought it made more sense that black holes would eventually rebound into white holes. I wonder when the new theory was introduced.
You made my day when you talked about the big bounce. I had that idea before but never heard it before from anyone else. Also, it feels good to give it a name. Sadly if our universe is expanding, that means the other is compacting. RIP our sister universe.
The first time I saw a white hole exploding I was in my teens.
Time slowed down for me at that moment.
Gravity seemed heavier just after.
For sure it was an event horizon.
Bouncy bouncy? YES PLEASE
That was a wild ride Alex.
