This is a map of the multiverse. Or in physics-ese, it’s the maximally extended Penrose diagram of a Kerr spacetime. And in english: when you solve Einstein’s equations of general relativity for a rotating black hole, the universe does not come to an abrupt halt at the bottom of the gravitational pit. Instead, a path can be traced out again but you do not end up in the universe that you started in. Like I said, it’s a map of the multiverse.

I feel like every time we see a Penrose diagram in Spacetime, it is slightly larger than the previous one.
A few episodes doen the line and we will meet the boss of penrose diagrams, bigger, and more incomprehensible
Soon we'll be able to play Penrose chess. And then the universe shall have fulfilled its purpuse.
It is known that Penrose diagrams grow over time.
Jonathan Luoto
Not only that, but the rate of growth of Penrose diagrams is accelerating! Leading to physicists hypothesizing the existence of “Dark Cartography”
That's just a result of living in an expanding universe.
I'm disappointed that the ring singularity wasn't called a "ringularity"
That’s fairly common, he just didn’t use that in this video.
It would be a mistake, because it is NOT a ring either.
It is "another donut" (like the ergosphere), defined as ~whatever~ new strange physics that -DOES NOT COMPUTE- [different than what governs our universe].
From wikipedia: "A ring singularity or ringularity is the gravitational singularity of a rotating black hole, or a Kerr black hole, that is shaped like a ring."
@@spammerspammer90 This is like trying to argument that a black hole is a "hole" in the "fabric" of spacetime.
-> There is no discontinuity at all!
Spacetime does not "rip" or "break" or "shatter" [the Penrose Diagrams depend on the conceptual entelequia that (time+space)=energy=information].
@@spammerspammer90 How DARE you cite Wikipedia! Don't you know it can be edited by anyone? It can't possibly be as reliable as this awesome sketchy site from 1492.

6:51 "Our balls, and the geodesics they follow, rebound and travel back out." -Matt O'Dowd, 2020
ThisFlyingPotato So say we all.
Didn't he also say something about repulsiveness of naked rings and plunging into them?
SupraGuy2jzgte yoo new pick up line! For my nonexistent game.
@SupraGuy2jzgte To sum up the video, once you go black you never go back
I bet it took several takes before he got through that part without him or anyone else in the room laughing
"this may sound fun, but there's the inconvinient fact of your utter obliteration" got a real chuckle outta me
Because that's not an "inconvenient fact", it's a flesh wound
I wonder if we could control quantum entanglement with particles active to observers when sending them to the black hole; all of his manners would be replicated in their entangled par to be viewed live by humans.
This is an especially great video, even by PBS-ST standards.. I've been waiting for this one since pt 1, and it didn't disappoint. Love the stuff on the inner structure of the Kerr black hole especially, there's next to no information about this online that doesn't require a graduate-level (or higher) understanding of math/physics to even be able to read.
Right? I'm glad I understood most of it after watching it like 20 times and doing research, finally. I hope we can one day try to explore black holes more and more

"Repulsive naked singularity"? Way to give the singularity body image issues, Matt.

I've been staying home, dealing with depression, everything is just kinda 'meh' in my life... And then this. No idea why, but I got so excited while watching this video! I muttered to myself multiple times in an effort to actually understand things, 'rewound' (is that word even used anymore?) probably a half-dozen times to make sure I really took in what was being said... This made me so happy. I'll never truly *understand* most of these videos, but it's so so fun to watch and think about anyways.
That's it, that's the exact same feeling I get. I watch them with an awe struck face trying to understand how there are some humans understanding things on a level I'll never be able to
But it's hypothetical unless we know for sure what singularity really is 😒
I had the same reaction. This is all theoretical but even the fact this is a possible is amazing. It really speaks to the fabric of space/time and how our universe functions. So much more research needs to be done but I doubt this gets the attention it deserves.
Break the cycle, raise above, focus on science, sis
"Be Kind, Rewind!" You're not alone, Margo. Stay safe, and stay sane, and don't feel like you can't reach out to someone, even if that one is a many and those many are internet strangers. Isn't this stuff just fascinating? :D

It made me think of death. Maybe we have to die (go through the black hole and get obliterated) to get to our next life (another universe). I'm not religious or anything, just a thought.

Question: So now that you've got this figured out for us, how about showing us what happens to matter and space time within these boundaries, but during a black-hole merger? Please and thank you :)
I'm going to go out on a limb and suggest that you probably don't want to be in there when that happens. Or would that be *where* that happens? We are flipping time/space coordinates after all...
@Kleos Huh? A "ruling bloodline" with the implication that he has some "insider" knowledge? Perhaps a fantasizing philosopher with a big ego.
The question "Are you really living on the planet you think you are?", while philosophical at heart, is more a question of semantics, because whether we live on a "planet" at all, and what particular planet it is called, is arbitrary semantics we've created to label something.
If the question revolves around whether
we've somehow been fooled or misunderstand our situation or are in the matrix, this is a very old conversation that goes back long before Rene DeCartes' famous line "I think, therefore I am". In other words: How do we really "know" anything at all aside from being a collection of thoughts? Fun topic, but nothing new or groundbreaking in philosophy.
@Kleos I will read further out of curiosity, but with all due respect, the Illuminati and anything related are more boogeymen than reality. To the rare "spiritually" enlightened person, and those who "like water" go with the natural flow and change of the world, any group/organization that might exist with such power will hold no sway over such a person.
To be fair, this is a rare minority, but any organization with power only achieves it in the minds of people. Without people thinking, believing, and following that which the Illuminati (or whoever) would want, they are powerless.
I would like to read this conversation you spoke of so I can get my thoughts on it.

Brilliant people. There's understanding then there's UNDERSTANDING. Its insane how deep the rabbit hole can go for what we believed to be simple.subjects from.a. vague point of view. Look at the proof for 1+1. Like wtf? You can proof what we thought we could take for granted.
Watches the video : yeah... I definitely understand it now...
~ A blackhole that has no spin or charge is basically neutral/static, it basically consists only of a mass constituent.
A neutral/static blackhole is essentially a wormhole without an E.M. energy jet stream.
~ A blackhole that has spin or charge has motion due to induced energy, so it is not a neutral blackhole but instead a dynamic/energetic blackhole.
It is essentially becoming a wormhole that has both motion & spin because of centripetal & centrifugal forces that are caused by induced energy, with more prominent Grav. blackhole & E.M. jet stream characteristics.
~ The more extreme the mass of the Grav. blackhole vs the more energetic the E.M. energy jet stream, the more prominent & extreme their mass/volume (density) characteristics become.
~ A neutral wormhole has a Grav. mass accretion disk & E.M. energy volume jet stream which are both in balanced density equilibrium.
The matter mass vs energy volume ratio is balanced/equilibrated.
A stable wormhole supports a peaceful existence for life.
Our solar system is close to being in this state, therefore it supports life as we know it.
~ Inertial Permittivity x Potential Permeability = Static/Dynamic Kinetics.
~ (Grav. Mass Accretion Disk Blackhole) / (E.M. Energy Volume Jet Stream) = Static/Dynamic Density Wormhole.

Ahhahahahahahhaha exactly
What does it mean to "fall" and "inside" mean when one crosses a black hole event horizon where, what was a space dimension intersecting the singularity, is now a time dimension that I presume now intersects the singularity?
In the best scenario, it goes in a loop, and it's still infinite, but it ends up back in our universe at some point. Also, the thing about space and time switching roles creeped me out. I had dreams about it. Thankfully, I'm glad the ergosphere gave me a boost out of there in those dreams.

Its why most people leave these videos utterly confused
Don't feel bad for having to rewatch multiple times or refer back to older episodes. Its part of the learning process friend
Yeah, seriously. Outside of most of the equations I tend to understand more than I would expect to of a lot of what Matt says, but for some reason he lost me so many times in this one. Definitely gonna have to come back again tomorrow too.
@@dustinjames1268 I would like to think I have a decent understanding on the intuitive level and thought visualisations that you need, to be able to follow most other Space Time episodes. This one just took, basically, all those previous videos about Penrose diagrams and black-holes and all the other spacetime breaking stuff and quick-fired them in a constant stream, while intertwining it all with each other.
I don't have a formal education in astrophysics, so all PBS Space Time content only gives me that "visual imagination" and "intuitive feeling" about how the universe works. The method hasn't failed me before this video. And even though the equations do make good sense to me, if you would ask me to rewrite them and use them in practice, I would not be able to. .... Yet...
Regarding this video, it is just a question of taking the time to sit down and break the events down in segments, and understand them one by one, and then chain the whole chain of events together. Across the multiverse style. ;)
But thanks for the encouragement.
@@semaj_5022 Exactly. ^^
6:16 No, this is not correct. It's easiest to see this in the Kruskal-Szekeres coordinate or the Penrose diagram. Also, space and time do not change directions, this is just an artefact of a strange coordinate system being used (namely, the one that results from first arranging the yet unknown metric into a diagonal form which is done merely to make solving the Einstein equation easier, or even possible, in a closed form). Such coordinate systems are singular at the horizons and due to a quirk of the mathematics involved, the letters labelling radial and time directions end up being reused at the resulting disconnected patches. But this is just a bit of notational laziness. Hawking and Ellis in their book try to counter this by switching the letters "r" and "t" for the interior portion of the Schwarzschild metric, for example. 7:33 It does not "become" repulsive. The ring singularity is gravitationally repulsive on both sides of the disc. The mass is not "negative", it's just that the radial coordinate labels become negative. Same thing about the "nakedness" of the singularity: it is so on _both_ sides (once inside the inner horizon), not just inside the "negative space". 14:15 This is very commonly asserted but it's just not true: Einstein was very likely not even aware of the Michelson-Morley experiment (USA was a scientific backwater then). His motivation was different: he was trying to resolve the infamous conundrum of Maxwell's equations not being true in a uniformly moving system. Since Newtonian mechanics obviously is not like that, and mechanics was supposed to be an effect of the microscopic electric and magnetic forces, this drove everyone crazy. His 1905 paper was in fact about justifying why the electromagnetic fields E and B were _physical_ after a Lorentz transformation (before him everyone assumed that those transformations were only mathematical curiosities). This was _the_ main conclusion of this paper in which he demonstrated how this reality of the transformed fields resolves the magnet-and-coil paradox he sets up in the introduction to the paper. But, as it very quickly turned out, probably within weeks of the publication, it was the first, kinematical (introductory) part of the 1905 paper that was the smoking gun (special relativity). So today hardly anybody even _reads_ the actual main (second, electrodynamical) part of the 1905 paper.
mindbogglingly conceptual yet, startlingly intuitive
"Now you're thinking with portals"
i'm totally imagining a sci-fi civilisation that teleports "singularity-mills" directly past the inner horizon to extract energy from the inner rotation, which would somehow be entangled to some turbines outside the black hole to make energy
None of it really make sense but it sound too cool so I need to create some lore around that. The madness of physics is just so much of a infinite well of inspiration
Not exactly this idea, but Kurzgesagt has a video on how to extract energy from black holes
You hit the nail on the head. This is all science fiction. For people who believe only in the physical world, this takes a bit too much faith for me
Again I have the feeling that if I whatch it 100 times I will get it... So it is not possible a white hole existing or matter going trough it but is possible that the fabric of space itself can go through it? If that will be possible, it will make sense that the big bang could be a white hole that is accelerating the fabric of our universe by pouring "space" into our universe "from another universe" and we will never be able to see it because it is in our past? It's a total non sense I know just curious and ignorant.
Great episode.
Thanks Matt. I just watched a lecture by Sir Roger Penrose at Gresham College and had to watch your video again in an attempt to learn a bit more. Turns out quite a bit more. Thanks again for your time and work putting it all together.

Penrose has also recently extended the diagrams to the left and right, in the Conformal Cyclic Cosmology model. Are we going to have an episode on that?
It looks implied that the left and right side extend infinitely. Again, it’s a donut
What if the Penrose donut ring was the ring around a black hole like Matt explained in his video which is inside a black hole. That would be mind blown!
@@ATX_Engineer mmm donut. Which means that The Simpsons is really on that time travel business
yes let's do!
Z Hud it’s 10pm and now I want a donut
A note on the mass inflation instability:
Out of the two perpendicular inner horizons in the diagram, only one has the instability if the black hole is not eternal. I.e. in a realistic scenario of a black hole which appears due to gravitational collapse, you can (sometimes) cross one inner horizon and get to the singularity without worrying about mass inflation. Also, at the horizon with the instability, backreaction seems to result in what is called a "weak" null singularity, "weak" because there are no divergent tidal forces and the geometry is extendable beyond it, so again not too much of a problem.
I was about to ask, these diagrams are for eternal black holes. Spinny ones, yes, but still unrealistic. I suppose Penrose diagrams are hard to make for non-eternal black holes of any variety...
None of the real black holes are eternal. So how are the Penrose diagrams for real black holes
I understood none of this so I guess this may be a legitimate physics talk.
@@timh.6872 They are not hard at all. Just take the bottom half of a Minkowski (flat) diagram and connect it to the top half of the black hole diagram. The line which separates them would be the surface of the collapsing matter distribution. Make sure that surface starts from a past timelike infinity of both diagrams, since you usually want its trajectory to be timelike.
Well, had to watch that one twice. Wow. Fantastic explanation. Thank you.
This explains how Sonic was able to turn back time during his fight with Speed Demon Mario in TerminalMontage's Subspace Emissary video.
He went so fast that he created a naked ring singularity out of pure energy (called a 'kugelblitz'), which allowed him to accelerate faster than light, which allowed him to jump back in time.

Ergosphere surface and event horizon diagrams are almost correct. The event horizon is the spinning sphere that we are contained in crumpled up inside. You learn how all of them are contained based on their spin and angels should line on at one point within our galaxy. Somehow I believe the forces line in some orientation towards or away from the great attractor. That is one of my crazy ideas.
Lets take a moment to appreciate everything Penrose has done for the advancement of our understanding of space-time, and the surprises that he might still have up his sleeve in his ever-ongoing research.
Nice tiles. But does that make up for his "consciousness" nonsense?
David Lloyd-Jones Is this nonsense only from when he’s at Rogans podcast or does he say this somewhere else?
@@Fleurlean4
I don't know anything about Rogan's podcast. I'm thinking of his claim about microtubules being the seat of consciousness for some sort of totally hocus-pocus reason, which I probably read about in some Scientific American, Martin Gardner, columns thirty years ago...
Purest lunacy.
David Lloyd-Jones Very strange.
Sooooo technically i can with my trusty map get "back" to the origin universe by going forward until i find a replia of it due to being able to go forward to new universes for as long as i want ... Got it....
Thought experiments aside, how would all this look like if we hold to our "knowledge" of not being able to exceed the speed of light in the torus on the other side of the ring singuularity, does it only do away with the time travel or the entire white hole part?
@CRIMNALSNEAK I loved this answer. If it weren't for you I would just say that we would die (ripped atom by atom) basically instantly before getting anywhere close to the singularity, that famous name that makes me want to go to my nearest italian restaurant
If the human mind is unable to visualize multiple universes, can a computer visualize multiple universes? It is simply a simple trick.
UA-cam why is this not trending?
instead of cosmetics or personal life related vlogs!!
this video is so well made and qualifies as good infotainment!!!
This is... absolutely crazy. Spacetime/timespace-based reality...
And thus, the opposite of gravity is intertia.
And velocity is the quintessential component of existence - as a passionate driver, I love that.
happiest moment of my day: seeing a notification from this channel
If watching this in a ringularity you would be watching time space instead of space time
Just to clarify, this concept of “multiverse” has NOTHING to do with the multiverse predicted by quantum physics, right? If there are two universes, one with the alive, and the other with the dead cat, I cannot use a black hole to travel from one from the other, because that is an entirely different concept, only the naming is similar.
Yes. "Many worlds" is the rationalization to explain the paradox of a literalist Copenhagen interpretation of superposition. Where as the relativistic multiverse is.... bending math to prove that hypothetical "other universes" exist. Both are effectively just mental exercises that don't exist.

I don’t know, ask Matthew McConaughey. He saved the whole world by doing that.
@Goaltender Interference awww why not ?
@Goaltender Interference i would
On the map, the multiverse you're referring to I suspect is represented by the "parallel universes", while the multiverse mathematically accessible is represented by "new universes".
This is among the trippiest videos I've ever seen . . .

When you think you understand, then you have to start watching all of the videos in the series again to figure out where you got lost.
Just got back from there. Nothing helped with "space and time switch". Was literally yelling wait! wait! at my phone while I was queuing the previous video. Lol
One of the most interesting Concepts have had the pleasure to think on. Thank you..
Your explanation of complicated science would make a great setting for star trek episodes
Question: As black holes are said to evaporate (something that I assume also applies to Kerr black holes), and space and time switch places beyond the event horizon, would the effect of passing through the event horizon effectively be the process of this evaporation? As you (a 3 dimensional object) pass through the Kerr black hole and are annihilated by these incredible forces, some of this energy and information is deposited in the form of energy during evaporation. So the white hole is actually a mathematical representation of this process of energy conversion.
In essence, the question I am asking is how much of this changes when not dealing with an eternal black hole? Is it simply interpretational or is it possibly completely different?
Interesting
I think it's probably completely different. All of these models are purely general relativity, you only get Hawking radiation when you start to mix in quantum mechanics. Adding in QM probably changes a lot of other things from these models but I bet we'd need a much better description of quantum gravity to know for sure.
No.
There's a reason they add eternal to the description for the equations, the equations don't solve a blackholes beginning, or its eventual end through Hawking radiation. For one, it came about before it could even solve for the second.
Sup dude, hawking radiation is the result of matter-antimatter particle pairs popping into existence right at the event horizon. Normally these pairs instantly annihalate eachother, but at the event horizon one particle is pulled in while the other particle is ejected. I forget how this ties into the black holes mass, but I know these pairs come from the mass of the black hole.
This video turned me into an unstable genius
Show me what you got.
Amith Ramsumair ...of the 10-26 dimensions thought to exist so far, depending which string theory you chose, one of them belongs to ideas and concepts. If ideas and concepts have their own dimension, then they could very well have their own form of “ecosystems”. That very well could be us. If we are the ecosystems for ideas and concepts, then we are simply reemergent algorithms and doppelgängers aren’t just physical...
Corporations call ideas and concepts “creatures”. We face one that religious scholars identify as “The Beast”. It’s a thought algorithm that, by its nature, seeks to end all life on earth. It’s supported by a movement known as “Zionism”.
What this all leads to is a challenge of creation. If there is no sentient life to gauge the existence of the universe, does the universe exist to begin with?
Unstable genius that...
🙃
Also, intelligence is relative as everyone is stupid in their own ways. I figured all this out by applying objective laws to political theory, and low beyond, the objective laws emulates physics..
Wow, super interesting! i've been thinking about this video for several days now
I love this series, including this one ...which is way beyond my understanding. I’m just trying to figure out if I need another beer or not.
I've always been a time traveller. Going at a steady pace of one second per second.
You're in the wrong newsgroup. You want reasonable-and-intelligent. Two doors down on the left.
Y'know, relatively speaking given the close proximity to Earth.
That's a chimo joke you just made
"Order of Hermes, or maybe Hufflepuff."
Man, if you thought the Mage RPG folks were coming for you before...
He’s a Void Engineer, if anything. :-)
That line cracked me up
True. He runs a Virtual Ecstactic show for... the Order of Hermes? What?!
its so crazy that this man came along with this revolutionary equations of relativity 100 years ago.
"I've always thought of myself as more Order of Hermes"
17 min talking about black holes, relatively and the multiverse, not even a passing mention of sympathetic links, destiny or the spirit planes: You're not fooling anyone, Technocrat.
Keep up the good work, though, this was very enlightening!
The Penrose diagram image at :40... I want that as a black light poster please.
I'll sell you one for 120
How much of the weirdness is actually weirdness, and how much is the math being broken? Because the whole "closed timelike curves" thing usually means math is broken.
IMO the “multiverse” part already means that math is broken. I mean, rotating black hole is something you can _make_. Assuming there are multiverses reachable from black hole, does it mean that you can actually make infinite multiverses by creating a black hole of arbitrarily small size? Sounds implausible.
@@eugenekozlov1504 implausible, but not contradictory. Closed tulimelike curves on the other hand are an open door to all sort of time travelling paradoxes.
It is only broken to the human mind , at some point our hardware cannot venture into.
@@eugenekozlov1504 I think it's more of a black hole connecting two universes together.
Drkwll but it is impossible. You cannot “open” black hole into existing universe. All universes you can possibly travel to contain exactly one eternal black+white hole. Therefore, these universes do not exist until this black hole forms.
Exactly: above the limited event horizon of physics is the spectacular ergosphere of Philosophy!
Love that Mage reference in there!
At every horizon is associated a Temperature, since Kerr (and Reissner-Nordström) Black Holes have two horizons an observer in the region between these two horizons does see both radiating?
I would think the inner horizon would only radiate inwards, since time-like paths can't travel out from it.
I always start these videos so strong, but things start getting really hazy around halfway through, maybe 3/4 on a good day. Thank you for being genuine education, not just edutainment. Not that there's anything wrong with that of course, I consume more than my fair share. I just appreciate the reality check. :-)
Me as a grad student with unfamiliar papers..
@@elck3 Roundabout halfway through I realize I'm just staring at the screen like a confused golden retriever.
Congrats for making it that far. Perhaps I could've followed this 15-20 years ago, when I was still in university and pretty accustomed to complex science, but fast forward to today and I find I've forgotten more about math and physics than I care to admit. ;)
hope that all the viewers understand your videos because they are awesome)

13:56 Almost forgot! Thanks for reminding.
VERY eye opening video. Thanks 😊 I totally forgot about penrose diagrams...
Been waiting for this episode a long time; seems you guys have a lot of stuff on your mind!
Great video, by the way.
Also, can you please print this map on posters? I would totally buy it, and so would other spacetimers.
Edit: Also please print it on a towel as quite a few people want it.

You seem like a real hoopy frood.
You already bought it 42 times and you just don't know it yet.
