I got a question regarding nuclear detonation. Will the wind also be affected by the coriollis effect, and if so, would the north hemisphere would have trouble with the fall out or it doesn't matter when it comes to the fallout?
Schwarz Schild Rot(h) Schild They all relate to the colors of coats of armor of old Families. The Schild means shield or in fact sign but more commonly the protective one in this case
31:50 Guess what?! My teachers been showing me more videos of Steve Mold and Hank Green channels, and some others, to explain complicated things quickly with visuals. (univeristy prep 12 U) They are better than most at explaining shortly, same way everytime. Their work has done us nerds well. Brady's Channels like Sixty Symbols (I think you may like) (Univeristy of Nottingham channels like Periodic Videos/numberphile/computerphile/deepsky and objectivity) smartereveryday, vertasium, list goes on.
@@dennisestenson7820 That's not the point. It's not a semantics nitpick, of course bids aren't machines. The point is that obviously it is physically/mechanically possible to fly without being lighter than air. Objectively. So the concept that a machine doing something a bird already does is "impossible" is really dumb.
Schwarzschild means both black sign or black shield in German. The latter seems even more fitting. Funnily if we put it as a verb "to shield" we use the verb "abschirmen" which comes from "Schirm" = umbrella. In the German dub of TOS star trek the shields are translated as Schirm (umbrella) and since TNG as Schild (shield)
@@BigWhoopZHI could see the logic in black corner/black ridge if older German naming convention was the same as some other places, like if it were referring to a geographical location: Arnold of Black Ridge mountain for example.
Another part people fail to talk about is the nucleosynthesis of the very heaviest of elements. They are formed from the neutrino flux when neutron stars collide or when the most massive of stars (~100M○) collapse. The inner shell around the core is so incredibly dense, and the neutrino flux is so high from the forming and collapsing neutron star, that the neutrinos can interact with the shell and "fuse" (through neutrino capture) the heaviest of elements. The true story of nucleosynthesis is a deep and very interesting topic that is overlooked by most.
Black holes weren't always called "black holes". They usually had the black part in the name but the whole phrase appeared in the late 1960s. Even in Star Trek TOS episode "Tomorrow Is Yesterday" from 1967 they refer to it as a "black star". Schwarzschild's name can be a small percentage of the reason why it is "black" (beside the obvious that even light "can't escape it").
"interstellar had its problems with physics" You say that but AFAIK they got several papers out of that movie and broke genuine new ground, the ringed black hole you see in the movie is the most accurate rendition to date
the papers were based on the simulation technique & formulas used for accurate yet fast simulations. Doesnt mean there's no problem with the physics of the black hole cuz dealing with very edge cases.
Yes, but sadly the wormhole is blatantly anything _but_ accurate. Kip Thorne created a realistic simulation of a wormhole, and the director didn't think it was exciting enough and ordered the "tunnel" visualization instead. This isn't necessarily a criticism; he was probably right, as the realistic visualization wouldn't even make sense as a "wormhole" to the general public, and most audience members probably would've just been very confused. Movies do have a useful lexicon, and using it is a valid choice, of course. Buuuuut then we go through the wormhole, and poof, we become Star Wars, where a single shuttle can go down and land and come back to orbit multiple times on a single load of fuel that goes, er... well. I'm not sure _where_ it goes, as the shuttle is about the size and shape of the passenger compartment. My problem with Interstellar has always been that it isn't internally consistent. It begins as hard sci-fi (multi-stage rockets made of almost entirely fuel, spin-gravity, multi-month travel time to the outer solar system), transitions to space opera (single-stage rockets with no space for fuel making multiple launches and landings, flitting around an even larger 'solar' system in hours or days, running with the coolest-looking idea that's kind of a loose nod to some concept in science with no regard for whether it's being depicted realistically), and ends as loosely tech-looking fantasy (multi-dimensional beings, time travel/reversed causality, and any pretense of a nod to science a distant memory). I guess they just hoped nobody would notice that they made three different movies and stitched them together at the horizons? Which to be fair, most people seem not to have... Also, there are _much_ more realistic renditions now. That black hole has... rather a lot of problems. Starting with the accretion disc being two-dimensional. I'm sure they could have done a realistic accretion disc; it wasn't that long ago and computing power hasn't increased all that much since then... but again, a realistic accretion disc wouldn't look so cool on screen, so...
Whenever I see a reaction video I expect the original video is going to get panned. So I was worried to see a reaction to Verastrium. But I'm glad you enjoyed his video!
He's reacted to a lot of Veritasium's videos. Seems to be a fan which I love because Derek's great at simplifying complex things, even if this one still goes way over my head in some places, even with it being simplified.
36:15 Sounds like what they're saying is that a parallel universe is just this universe, but outside of the edge of our 'visible' universe? That's why there's the ability to see the light of their universe, thus seeing their effect, while they remain outside of where we can physically go?
There are many different types of the parallel universe idea, some existing together. For example, a part of space that is similar just by coincidence because there is so much space, or a universe in a different time line, or a universe before or after ours, or a universe outside ours etc.
Yeah, for example a paper is 2d universe, If you pass a 3d object, like your hand into that universe. Only 1 layer of your hand is in the 2d verse, let’s say we have a book, which can be refer as 2d multiverse (as 1 paper is 1 2d verse). Then based on your point the 2d universe still infinity large, but cant cross the other paralel universe
38:45 the Einstein field equation is a tensor equation, thus coordinate free. When you solve it, you choose coordinates to solve it in. These are the results of Schwartzschild's (albeit natural, but arbitrary) choice.
Just found your channel a couple of days ago and have watched so much of it. It helps that I've seen a lot of the original videos already. I've always found nuclear energy and nuclear weapons fascinating, at least from a distance.
I mean... there's a bit of a difference between saying, "Heavier-than-air flying machines are impossible... just ignore that bird over there demonstrating otherwise, oop, and that one as well. And that one. Dammit... stop it, birds! I'm trying to claim what you're doing is impossible!" and saying "Wormholes are impossible because they would require negative mass and we have absolutely no indication that that exists or even could exist and very good reason to believe it _can't."_
It's very hard to directly observe a black hole. When we look towards the center of our own Milky Way, we don't see a black dot or any kind of point. We see the bright light of gas and dust of the birth and death of stars around Sagittarius-A star. In fact, the 1st observations of black holes weren't Sagittarius-A Star. We noticed the black dots out in other galaxies as they transit other stars and galaxies.
Thanks for analyzing this so thoroughly despite the video already being pretty thorough for its educational nature. Watched both of them, now it makes even more sense.
Life’s biggest unanswered questions: What is his name? What is his job? How many years of experience does he have? Does he claim to know everything nuclear?
my professor once introduced me a concept of what if we calculate time as space itself. you see here on Earth we always calculate space and time as a different variable, how much time do it takes to go from here to there, that's always happend right? so he came up with this concept of calculating time and space as a single variable, so basically time is space itself. with this concept in mind, I remember he was trying to simplified Einstein's theory of relativity, but I don't think I've seen the finished equations of that tho'. but honestly, with this concept, those 2D diagrams (x and time variable), that always become our sort of "boundary", can be simplified and we can add more "dimensions" to the diagram.
A bit more "in depth" discussion would be to look in to the "big rip" scenario. When you look at the overall characteristics of a "big rip" endstate, you see that quarks are being pulled apart at the speed of light, and when doing so, the gluon energy will spawn a new quark of each that is pulled apart. Now, compare that to the characteristics of the "big bang" in which, all of space is expanding FTL and there was innumerable quark generation happening. I didn't major in cosmological physics, but when two events share such glaring similarities, it's worth looking in to, and very few have. Issac Arthur has touched on the topic a bit since I brought the idea up several years ago to him, but he, like myself, lacks the mathematics to dive deeply in to it.
i always thought of the similarities between what is conceived as the reality of the big bang, meaning all of everything in one infinitely small space before exploding outwards to be remarkably similar to a black hole, only the opposite. the singularity of a black hole is everything it has ever eaten compressed into an infinitely small space. so, what if, at the end of the universe when all the black holes have eaten each other, the singularity is functionally one in the same as the big bang? Additionally, a different theory i have, with all the time warping that black holes cause due to the relativity of time, couldn't a black hole actually be LEADING to the beginning of time? if its infinitely compressed and infinite gravity then due the nature of time you could travel back in time through a black hole, the only issue being dying in the process. so what if the universe is one gigantic paradox where it makes itself forever ad infinitem? since all matter will be absorbed by black holes at the end of time, and shoved right back to the beginning of time? maybe thats how it all appeared at once as nothing more than a cosmic soup of quarks and shit, since black holes rip molecules into their base parts? food for thought
I had a thought kind of similar to this. Which i havent found it yet but I'm sure im not the first to think this, but i believe the entirety of the universe is shaped like a toroid (donut). The "north" pole is where we are going, and the "south" pole is where we started. The big bang is not one event, but constant. Dark matter would be equivalent force to what we would view as magnetic field / flux. It doesnt interact with itself yet is a driving force. I think that us only seeing black holes is just because are still in the lower half of our travel around the field heading back to the north pole "core". Once we cross over or get close to the half way point we would start seeing white holes as black holes are essentially wormholes leading to the upper half. The gravity was so intense in a black hole it created a tunnel to the upper half where its a white hole spitting out all the matter that entired the black hole.
Or the "expanding universe" is really just us falling into a black hole and the distant galaxies we see are red shifted because of the curvature of the black hole?
Do you think you could have a look into doing a reaction to a video called "The Star that Shouldn't Exist" by Cool Worlds? There Cool Worlds talks about Przybylski's star upon which astronomical observations have noted that (and I'm paraphrasing here) superheavy elements in the photosphere of the star, that just outright don't belong for a star to have.
If anyone is more knowledgable about it, please correct me if I am wrong, but: Wouldn't white holes just be like perfect camouflagers? Since they never let anything enter, they would then bend light away from them and create weird distortions in spacetime, like how black holes are detected by their effect on other objects in space. But even more so because they wouldn't even be black, so *MAYBE* if you looked at one you would even be able to see yourself if the light coming from you even got pushed back towards yourself (HEAVY speculation without any basis for that though). By that definition though, they could definitely be white as well as the light coming from all directions would be bent towards an observer, and all colours would then be seen as white. But then they could also just be some sort of star colour like some type of whitish orange/red colour. If they do exist, maybe thats why we can't find them, they just look like a star. Chances of them existing are next to 0 since they require some WEIRD physics only applicable in theory, but perhaps. Given infinite time, infinite possibilies happen an infinite number of times, so who knows. Maybe they existed extremely early in the universe. Or they do exist outside of the observable universe, the observable universe compared to the estimated size of the universe is like a light bulb inside of pluto after all. Sorry for the yapping, I love this stuff lol. But like I said, if anyone who knows more about it please correct me because I am fascinated by this.
"Schwarzschild" could be translated as "black sign", yes. Though you would normally go for "schwarzes Schild" instead, rather than turning that into a single noun. However, "Schild" also means shield. I suspect that is the actual origin of the name. When I heard it, I didn't even consider that it could mean sign until you pointed it out - I immediately thought of it as shield.
Schwarzschild is Schwarz + Schild. Schwarz is "Black", as you said. "Schield" can mean "Sign" as you said, but it can also mean "Shield" or "Barrier" (like, the Star Trek "Shield" they're using to protect their Ships could be translated as both "Schild" or even "Schutzschild" or "Protection schild" / "Barrier"). So yeah, the coincidence is quite big that a guy named "Schwarzschild" is the namegiver for the "Schild" (Shield) around a "Schwarzes Loch" (Black hole).
For the inabilty of information sharing through the whole rotating blackhole whitehole shenanigans, the most likely way we would get to confirm it would be someone coming into our universe from another one down (on that model). Ofc the issue there would then if we believed them, or would take them for a mad man's ramblings :D. Though if that happened, it would only be fair we ourselves sent someone "upwards" so the people living further up also get the chance to get the same knowledge.
dont the doppler effect need time and force to be in a straight line to the receiver ? so in a black hole that the forces are "bent" you need to be in the "bent" path or will you see the same thing as we seen with quantum waves or other observations ? That we need to be in the "path" to see the real other wise be are seeing object moving past us in other directions like wen you stand i front of a car you see the whole thing. But if you look from the side true a ole in a plank it will only "blink" ?
notice the shade color in each square, it fools the eye vision when 2 squares are needed to fill what one squared field at first sight of the video,,, it keeps fooling the eye vision..
what is also interesting is that david bowie, who is on the shirt of the physicist in this video, was the one that sang the song called "Blackstar," which is a fun fact.
The vision thing you mentioned, you'd need Stereoscopic 3D vision, which would mean seeing an approximation of 4D, where we only have stereoscopic 2D vision that is pieced together to create an approximation of 3D
47:35 - Doesn't that suggest a causal chain of some sort, as you see in Anathem? Each universe downstream can't communicate back but you can continue forward, exploring the strangeness ahead?
The wire will just get ripped apart. It would need a tensile strength high enough to allow its atoms to stay away from a black hole relatively faster than light.
Wait, this just occurred to me. I have been looking into this subject for a while. Wouldn't the fact that a Black hole has mass that changes shape with rotation imply that a wormhole can't actually occur?
Though, interstellar has practically no flaws in terms of physics. The only few were made because of the intiative of Cristopher Nolan, to make the movie more entertaining. The movie has the book "directors edition of interstellar", written by Kip Thorne with all formulas and explanations, you can take a look in your free time.
1 problem with the theory of Relativity & special relativity is it fails at the quantom level & 2 is that it disagrees with the standard model of particle physics. So we definitely are still close to a major breakthrough in quantom fields & gravity but just are yet to find the right stuff to make it clear to us.
From the diagram , it seems time mathematically cant seem to go backwards in time because it requires the ability to send information beyond the speed of light. Or bend space backwards and have your lightcone point backwards.
It was very interesting that Veritassium put thiis out and then Dr. Becky put out a video about the Axis of Evil, which was related in that it raises questions about the shape of the universe. I'm not good at explaining, but I saw them as related lol. you might find that Dr. Becky video interesting.
correct me if I'm wrong. if you go to the Antiverse and go into the Antiblack hole can you go back? if gravity is flipped the black hole becomes the white hole and the white hole becomes the black hole and one thing. if the anti-verse has the opposite time you just go back and forth into the black hole and so on and so forth so you can't go into the anti verse
I highly recommend checking out the 'Minecraft SCADA' channel. She has created a VERY NICE in-depth S.C.A.D.A. setup on minecraft with a mod called ComputerCraft to control and manage all her turbines, fission reactors, automatic fuel reprocessing, etc. Here is her setup showoff/trailer video title "ComputerCraft + Mekanism SCADA Beta Release"
14:45, IMHO, the interior of a black hole (within the Schwartzchild radius) doesn't a contain a singularity, but instead is a quantum particle an infinite energy well. This a physical realization of the quantum mechanical idea of the particle in a box.
And all along i thought that crossing the event horizon would make you disappear then return 7 years later as absolute evil with sharp needles sticking out of your head.
The map of infinite universes could simply be too large for us to gather knowledge to calculate outside our observable universe as well. And maybe the signs of whiteholes are just the big bang making two more, then two more, in excess, exponentially growing, maybe even repeating most aspects with slight variations per dual branch created. If any variations, then that'd mean the field/plain we are on could be curved as well. Showing that time/space/light is impossible to cross, but nature says it should in some way. Maybe all at once for a new universe? Like a balloon or Bubble popping into a wider area. (more dense in smaller area, but overall more area covered if you include the gas or water in the balloon popping into differen't pieces and spreading gas/liquids everywhere. Entropy ect.)
Maybe I'm missing something, but isn't the "parallel" universe just our universe, but it appears there since we squashed cones into triangle? So if you would restore one more spacial dimension, and make graph 3d instead of 2d, our universe would be around the cone of black hole? There were some other transformations applied to the graph, so maybe they prohibit restoring of this dimension in this way though. Edit: to clarify, I mean the first parallel universe, in non spinning black hole.
Seems pretty plausible to me. This is all so silly that I'd not be surprised if few people actually bothered to go through and check it all super carefully who knew what they were doing and actually transformed it to other projections etc.
I wonder what happens when electrons do eventually touch just from the force. (Like forcing 2 weak magnets to touch but obv much stronger lol) Is that what creates blackholes? When there is enough mass to make electrons or whatever particles to touch
If it's an Anti-verse time would go backwards like he said, so you would be forced to go back, and infinity be stuck in a loop of going in and out of the singularity, right?
The diagram reinforces my belief that the Big-Bang - as Neil Turok postulates - is a mirror. As a result, time would only run backwards from ours perspective in the parallel universe. From the perspective of the parallel universe, the white hole would be a black one and time would pass like in our universe. (By the way, the antimatter-puzzle would be solved)
What if the diagram at 39:32 was circular, things go into the black hole from our universe and can get spit out into the parallel, and things from the parallel universe goes into the white hole and spit out into our universe but we are all going forward in the universe we happen to be in and can't see whats being sent out from the white holes behind us, so the parallel universes white hole would be what our universes black hole, and the parallel universes black hole is our white hole, idk how the math would work, that just something my brain thought of
I might have missed it but why can't the coordonate system be connected at 36:21. Why did they propose the idea of another universe instead of simply just the same one? So that our universe is connected to the singularity both left and right
so does that mean the singularity is absolute zero, aka when time stops, atoms and electrons stop moving. this can only occur at absolute zero. As far as I'm aware.
Hold on new theory, what if a white hole is actually just the big bang? Its depicted at the bottom of time And going through a blackhole sends you to a different universes big bang.
I got a question though... When light gets absorbed by an atom and before it gets emitted again, what does the atom do? I only know an electron will go to a different shell briefly and fall back while emitting that photon, but while in that higher energy state does the atom jiggle more? Is it possible to shed this energy by bouncing into a different atom, preventing the photon from being emitted?
Yes and no. Atomic collision in such a scenario would be rare (here on earth where we see photon emission from electron field changes) because of the shared repulsion between the two atoms, or more correctly, between their electron fields. WERE they to collide, the energy could be transferred to the neighboring electron field, but that electron field would behave just as the original field and emit a photon when the electron dropped back to a lower energy level.
@@John-ir2zf Fascinating, I would have expected such repulsion to also cost some energy, hinting at the possibility that neither atoms would have sufficient energy to emit the photon, given that they need to be in discrete packages. But nature probably has a law against that haha :P
@Yezpahr the repulsion effect is inherent. It just "is", and doesn't require any outside energy to exist or to perform its function. It's a fundamental property. The energy gained by the electron field has to go somewhere because the excited electrons are unstable in a higher energy state. I would need to spend some time thinking it over, but ionic bonding could possibly occur if several electrons where raised to a higher energy state, and another element could "grab" on to those electrons and incorporate them in to its own electron field via an ionic bond. Not certain which elements would need to be involved though and the conditions the bonding would need to happen 🤷♂️
@@John-ir2zf Thanks for filling in the massive holes in my understanding. I picked up tiny pieces of wrongthink over the years without realizing. Example, I literally thought "energy's" could just flow over randomly to another type, seems to hold true most of the times. Kinetic energy to heat, heat to light, light back to heat, so for a noob like me it wouldn't be a stretch to wrongly think kinetic energy was transferred in those moments of repulsion. Nature's layers of complexion is baffling, thanks for lifting the veil a bit.
Ill try and do a quick summary of the geometry of the interior of a black hole. The classic, "swirling drain" metric is appropriate for the approach TO the event horizon, and over it. But, when you approach the singularity itself, at the bottom of the "swirling drain", you will encounter the inverse shape of that "swirling drain", the singularity will be sitting atop a increased curvature space. Think of the rebound in water when a drop falls in. The only place to navigate past the event horizon, is near the bottom of the EH "swirling drain" where the space equals out between the EH "swirling drain" and the singularities "rising" curvature. These are difficult ideas to grapple with, and even more difficult to explain coherently.....
@gabusdeux that requires an expanded understanding of "time". Time, as we think of it, is merely our experience of individual moments along a continuous "line of time". In actuality, , the entire "line of time" already exists and we are merely seeing it play out as it does because of our narrow understanding. We can not see the entire "line of time" at once because we are 3D organisms, with 3D comprehensive ability, in a 4D framework with time being the 4th dimension and all of that dimension occurs around us, all at once, everywhere. Time dilation near a black holes event horizon, is a product of us struggling to comprehend the fact that "time" is not static or flowing in any direction, forward or backward. if we were to step across the event horizon, what do you think "time dilation" would be like just on the other side ? Would the dilation increase ? And what does that dilation increase look like, if, at the event horizon it reaches maximum and "time" stops for the reference frame of the people viewing it. It will be a long time before most of humanity can shrug off that linear flow thinking and begin to see that "time" is irrelevant. I know that's not an explanation of your question, but that's only because there is no explanation of your question when you understand that all of time exists at every moment that we experience....
Hi. I just found your channel. I do not like describing mass a curving space. I think there must be a simpler way to describe it. I like to think about space having its own kind of density. Mass accretions would be areas of low density space. Hell, I dont even totally buy the expanding universe idea either. When Hubble first found this warnings were given by others to not fall into the trap of thinking about it as a recessional velocity. I appears that way. Thats it. I have a few questions you may or may not enjoy. 1.If a 10 solar mass star collapses to form a black hole what is the remnant mass and how big is the horizon? I could work it out on my own but I am in hectic mode at the moment plus I would like to see the solutions of others as well. 2.Is it not likely that the permittivity and permeability of free space become severely altered under these conditions? I look at black holes as possibly being recycling mechanisms in the universe. It may even be that at such intensities a complete coupling with either space or dark matter occurs. Maybe thats why dark matter halos form around galaxies. They just dont completely couple but cause sufficient perturbance to start the effect. 3. When 2 neutron stars collide I know heavier elements are formed from a portion of the debris. Could it not also be that Hydrogen is regenerated in these events since I am sure a decent number of free neutrons must escape as well? these would decay into protons, electrons and anti-electron neutrinos and eventually the protium would find another electron, right? 4. :Last one. I have already said I dont fully accept the current reason for the cosmic redshift but let me ask something. We should be able to verify this once and for all if we can do this. We have redshift at distance which is being attributed to expansion. We also have a distance/brightness relation. At what distance should we be able to see the brightness shift as we are observing the supposed recession?
Hey you might want to react to this guy who bought some nuclear testing equipment and made a synthesizer, the channel name is FLESH SIMULATOR he is a musician, its his last video, pretty dope. Ill try to post the link bellow.
I've always wondered if speed was the answer to survive falling into a black hole. You get spaghettified because your lower body is being pulled faster than the top, but if you matched the "terminal velocity" of that gravitational pull before you entered, then your ship / body wouldn't be accelerated at a different rate and be pulled apart. Which I've been learned it's impossible for mass to travel at 100% the speed of light (if that's actually true) but if we could go 99.99999% that speed, i feel we could reach a point where the added pull wouldn't be too much and cause us to be pulled apart, just accelerate us that little bit more in one piece
No need for such efforts - just use a bigger black hole. The change in space time curvature, and thus tidal forces, will be more gentle and you could glide calmly through the event horizon. At least if you survive the from your perspective blue shifted radiation.
@@robertmartinu8803 that was another thought, as massive as black holes are, would it really even spaghettify us? I mean, you drop an ant on earth, and it doesnt hit terminal velocity the same as we do and splat on the ground. It kinda just glides down. Maybe that's more to do with air resistance given its tiny mass. However, still relative to the black hole, we would be teeny tiny. Although i believe the gravitational pull would be too strong to escape at a certain threshold, i wonder if our size relative to the BH would lessen the impact of the gravity trying to rip us apart.
@@kylewellman402 It's basically a matter of the ration of the distances between the center and your head vs center to your toes. If the ratio is 1:1 (an infinity black hole) everything of you feels the same gravity and accelerates at the same rate thus you feel nothing. For the supermassive black holes in the centers of galaxies that works out to be survivable. But a stellar mass black hole has its event horizon sitting much closer and you get a ratio different from 1. Your lower parts experience more gravity then the upper ones, because the latter ones are still further away - until the difference in acceleration causes forces that exeeds your tensile strength. Similar idea to the Roche limit, just more extreme.
@@robertmartinu8803 so our size relative to the size of the black hole does make a difference. We should be able to approach and enter a super massive without fear of getting pulled apart, but the little fellas the size of earth with a few solar masses are the ones that will rip our molecules apart lol
I still don't get why everybody alwas equates the formation of a black hole to the formation or automatic existence of a singularity. A black hole requires a high mass density but not an infinite one. And wouldn't centrifugal forces alone balance gravity at some point in the star collapse way before reaching r=0?
Speaking of Alessandro Roussel from ScienceClic, I'd reaaaaaally encourage you to react to his videos on his channel !! It's one of my favourite science vulgarisation channel on RUclips, and he does really great animations and simulations ! It's originally a French channel (it has english subtitles I believe), but he also had one voiced in English for some time now ! - A french viewer of yours 🤓
The white hole seems to not really be mostly go into our world, the mass coming from a white hole seems mostly only go inside the black hole, and if something were to actually make it into our world, it would have to move at the speed of light in the infinite past. Anything not moving at the speed of light within the white hole will with most likeliness just end up in the black hole.
They go ENTIRELY into the world. The whole top line only borders normal universes in the diagram, so you have to spend some time in a normal universe after being in a white hole before you can go back into a black hole again. Even at the bridge, it's a single point, no actual photon or anything can fit through it, like they said earlier, before the bridge pinches off.
are you really spaghettified, if gravity stretches space, and not stretching you across a given space? You're still "occupying" the same amount of space right? But at the same time, light can also be stretched when space stretches, and it changes the light so i guess we do become spaghetti.

"Heavier than air flying machines were impossible" Uhhh was Lord kelvin unaware of this cool thing called "birds"?
ikr 😅
You see, there were no birds yet! The government haven't made the drones yet
He didn't consider birds to be machines.
@@dennisestenson7820 That's not the point. It's not a semantics nitpick, of course bids aren't machines. The point is that obviously it is physically/mechanically possible to fly without being lighter than air. Objectively. So the concept that a machine doing something a bird already does is "impossible" is really dumb.
@@gavinjenkins899 Kelvin was talking about the practical possibility of creating such a machine, not the physical possibility.
Schwarzschild means both black sign or black shield in German. The latter seems even more fitting. Funnily if we put it as a verb "to shield" we use the verb "abschirmen" which comes from "Schirm" = umbrella. In the German dub of TOS star trek the shields are translated as Schirm (umbrella) and since TNG as Schild (shield)

Another part people fail to talk about is the nucleosynthesis of the very heaviest of elements. They are formed from the neutrino flux when neutron stars collide or when the most massive of stars (~100M○) collapse.
The inner shell around the core is so incredibly dense, and the neutrino flux is so high from the forming and collapsing neutron star, that the neutrinos can interact with the shell and "fuse" (through neutrino capture) the heaviest of elements.
The true story of nucleosynthesis is a deep and very interesting topic that is overlooked by most.
German dude here.
I would translate Schwarzschild to Blackshield instead of Blacksign. But its a name so both are technically correct I guess

Black holes weren't always called "black holes". They usually had the black part in the name but the whole phrase appeared in the late 1960s. Even in Star Trek TOS episode "Tomorrow Is Yesterday" from 1967 they refer to it as a "black star". Schwarzschild's name can be a small percentage of the reason why it is "black" (beside the obvious that even light "can't escape it").
"interstellar had its problems with physics"
You say that but AFAIK they got several papers out of that movie and broke genuine new ground, the ringed black hole you see in the movie is the most accurate rendition to date
the papers were based on the simulation technique & formulas used for accurate yet fast simulations. Doesnt mean there's no problem with the physics of the black hole cuz dealing with very edge cases.
Yes, but sadly the wormhole is blatantly anything _but_ accurate. Kip Thorne created a realistic simulation of a wormhole, and the director didn't think it was exciting enough and ordered the "tunnel" visualization instead. This isn't necessarily a criticism; he was probably right, as the realistic visualization wouldn't even make sense as a "wormhole" to the general public, and most audience members probably would've just been very confused. Movies do have a useful lexicon, and using it is a valid choice, of course.
Buuuuut then we go through the wormhole, and poof, we become Star Wars, where a single shuttle can go down and land and come back to orbit multiple times on a single load of fuel that goes, er... well. I'm not sure _where_ it goes, as the shuttle is about the size and shape of the passenger compartment.
My problem with Interstellar has always been that it isn't internally consistent. It begins as hard sci-fi (multi-stage rockets made of almost entirely fuel, spin-gravity, multi-month travel time to the outer solar system), transitions to space opera (single-stage rockets with no space for fuel making multiple launches and landings, flitting around an even larger 'solar' system in hours or days, running with the coolest-looking idea that's kind of a loose nod to some concept in science with no regard for whether it's being depicted realistically), and ends as loosely tech-looking fantasy (multi-dimensional beings, time travel/reversed causality, and any pretense of a nod to science a distant memory). I guess they just hoped nobody would notice that they made three different movies and stitched them together at the horizons? Which to be fair, most people seem not to have...
Also, there are _much_ more realistic renditions now. That black hole has... rather a lot of problems. Starting with the accretion disc being two-dimensional. I'm sure they could have done a realistic accretion disc; it wasn't that long ago and computing power hasn't increased all that much since then... but again, a realistic accretion disc wouldn't look so cool on screen, so...
@@barefootalien I'm not sure how much I even remember of Interstellar. I was too busy adjusting the volume.
@@Yotanido Heh, yeah, movie equalization, or the lack thereof, is um... problematic at times, isn't it?

Whenever I see a reaction video I expect the original video is going to get panned. So I was worried to see a reaction to Verastrium. But I'm glad you enjoyed his video!
He's reacted to a lot of Veritasium's videos. Seems to be a fan which I love because Derek's great at simplifying complex things, even if this one still goes way over my head in some places, even with it being simplified.
You say science-fiction, i say science-speculation
36:15 Sounds like what they're saying is that a parallel universe is just this universe, but outside of the edge of our 'visible' universe?
That's why there's the ability to see the light of their universe, thus seeing their effect, while they remain outside of where we can physically go?
There are many different types of the parallel universe idea, some existing together. For example, a part of space that is similar just by coincidence because there is so much space, or a universe in a different time line, or a universe before or after ours, or a universe outside ours etc.
According to the diagram it should be a mirror universe rotated around the time axis
Yeah, for example a paper is 2d universe, If you pass a 3d object, like your hand into that universe. Only 1 layer of your hand is in the 2d verse, let’s say we have a book, which can be refer as 2d multiverse (as 1 paper is 1 2d verse). Then based on your point the 2d universe still infinity large, but cant cross the other paralel universe
schwarzschild = Blackshield one possible translation
Definitely my favorite video you've covered. Love to see you cover more veritasium videos
38:45 the Einstein field equation is a tensor equation, thus coordinate free. When you solve it, you choose coordinates to solve it in. These are the results of Schwartzschild's (albeit natural, but arbitrary) choice.
Just found your channel a couple of days ago and have watched so much of it. It helps that I've seen a lot of the original videos already. I've always found nuclear energy and nuclear weapons fascinating, at least from a distance.
I mean... there's a bit of a difference between saying, "Heavier-than-air flying machines are impossible... just ignore that bird over there demonstrating otherwise, oop, and that one as well. And that one. Dammit... stop it, birds! I'm trying to claim what you're doing is impossible!" and saying "Wormholes are impossible because they would require negative mass and we have absolutely no indication that that exists or even could exist and very good reason to believe it _can't."_
It's very hard to directly observe a black hole. When we look towards the center of our own Milky Way, we don't see a black dot or any kind of point. We see the bright light of gas and dust of the birth and death of stars around Sagittarius-A star. In fact, the 1st observations of black holes weren't Sagittarius-A Star. We noticed the black dots out in other galaxies as they transit other stars and galaxies.
Thanks for analyzing this so thoroughly despite the video already being pretty thorough for its educational nature.
Watched both of them, now it makes even more sense.
schwarzschild means black sign, or black shield.

5:30 Casting shade on the Surveyors Dx
my professor once introduced me a concept of what if we calculate time as space itself. you see here on Earth we always calculate space and time as a different variable, how much time do it takes to go from here to there, that's always happend right? so he came up with this concept of calculating time and space as a single variable, so basically time is space itself. with this concept in mind, I remember he was trying to simplified Einstein's theory of relativity, but I don't think I've seen the finished equations of that tho'. but honestly, with this concept, those 2D diagrams (x and time variable), that always become our sort of "boundary", can be simplified and we can add more "dimensions" to the diagram.

Doctor Who has played with this thematic in at least two separate 2 part episodes during the new Who era (2005 and going)
Ring singularity or ringularity is what we think happens in black holes that rotate fast. Loved that pun😂
Could it be possible that the "big bang" was, or is, a white hole?
You're not the first to ask that question. Dr. Becky made a video on that.
A bit more "in depth" discussion would be to look in to the "big rip" scenario.
When you look at the overall characteristics of a "big rip" endstate, you see that quarks are being pulled apart at the speed of light, and when doing so, the gluon energy will spawn a new quark of each that is pulled apart.
Now, compare that to the characteristics of the "big bang" in which, all of space is expanding FTL and there was innumerable quark generation happening.
I didn't major in cosmological physics, but when two events share such glaring similarities, it's worth looking in to, and very few have.
Issac Arthur has touched on the topic a bit since I brought the idea up several years ago to him, but he, like myself, lacks the mathematics to dive deeply in to it.
i always thought of the similarities between what is conceived as the reality of the big bang, meaning all of everything in one infinitely small space before exploding outwards to be remarkably similar to a black hole, only the opposite.
the singularity of a black hole is everything it has ever eaten compressed into an infinitely small space.
so, what if, at the end of the universe when all the black holes have eaten each other, the singularity is functionally one in the same as the big bang?
Additionally, a different theory i have, with all the time warping that black holes cause due to the relativity of time, couldn't a black hole actually be LEADING to the beginning of time?
if its infinitely compressed and infinite gravity then due the nature of time you could travel back in time through a black hole, the only issue being dying in the process.
so what if the universe is one gigantic paradox where it makes itself forever ad infinitem?
since all matter will be absorbed by black holes at the end of time, and shoved right back to the beginning of time?
maybe thats how it all appeared at once as nothing more than a cosmic soup of quarks and shit, since black holes rip molecules into their base parts?
food for thought
I had a thought kind of similar to this. Which i havent found it yet but I'm sure im not the first to think this, but i believe the entirety of the universe is shaped like a toroid (donut). The "north" pole is where we are going, and the "south" pole is where we started. The big bang is not one event, but constant. Dark matter would be equivalent force to what we would view as magnetic field / flux. It doesnt interact with itself yet is a driving force. I think that us only seeing black holes is just because are still in the lower half of our travel around the field heading back to the north pole "core". Once we cross over or get close to the half way point we would start seeing white holes as black holes are essentially wormholes leading to the upper half. The gravity was so intense in a black hole it created a tunnel to the upper half where its a white hole spitting out all the matter that entired the black hole.
Or the "expanding universe" is really just us falling into a black hole and the distant galaxies we see are red shifted because of the curvature of the black hole?
Wow you never heard of the The Schwarzschild Radius ??
Do you think you could have a look into doing a reaction to a video called "The Star that Shouldn't Exist" by Cool Worlds? There Cool Worlds talks about Przybylski's star upon which astronomical observations have noted that (and I'm paraphrasing here) superheavy elements in the photosphere of the star, that just outright don't belong for a star to have.
Damn Ty, that image and your comment could be a marriage proposal. 4 real 4 real. "Ringularity."
It's a new word, too.
If anyone is more knowledgable about it, please correct me if I am wrong, but:
Wouldn't white holes just be like perfect camouflagers? Since they never let anything enter, they would then bend light away from them and create weird distortions in spacetime, like how black holes are detected by their effect on other objects in space. But even more so because they wouldn't even be black, so *MAYBE* if you looked at one you would even be able to see yourself if the light coming from you even got pushed back towards yourself (HEAVY speculation without any basis for that though).
By that definition though, they could definitely be white as well as the light coming from all directions would be bent towards an observer, and all colours would then be seen as white. But then they could also just be some sort of star colour like some type of whitish orange/red colour.
If they do exist, maybe thats why we can't find them, they just look like a star. Chances of them existing are next to 0 since they require some WEIRD physics only applicable in theory, but perhaps. Given infinite time, infinite possibilies happen an infinite number of times, so who knows.
Maybe they existed extremely early in the universe. Or they do exist outside of the observable universe, the observable universe compared to the estimated size of the universe is like a light bulb inside of pluto after all.
Sorry for the yapping, I love this stuff lol. But like I said, if anyone who knows more about it please correct me because I am fascinated by this.
"Schwarzschild" could be translated as "black sign", yes. Though you would normally go for "schwarzes Schild" instead, rather than turning that into a single noun.
However, "Schild" also means shield. I suspect that is the actual origin of the name. When I heard it, I didn't even consider that it could mean sign until you pointed it out - I immediately thought of it as shield.
Hey Tyler can you do a video on Kyle Hill's video of Douglas Crofut
Schwarzschild is Schwarz + Schild. Schwarz is "Black", as you said. "Schield" can mean "Sign" as you said, but it can also mean "Shield" or "Barrier" (like, the Star Trek "Shield" they're using to protect their Ships could be translated as both "Schild" or even "Schutzschild" or "Protection schild" / "Barrier").
So yeah, the coincidence is quite big that a guy named "Schwarzschild" is the namegiver for the "Schild" (Shield) around a "Schwarzes Loch" (Black hole).
Thumbs up for the Ringularity, lol
If only Lord Kelvin had the foresight to upload his reaction to the Wright Brothers' first flight...
Can you do a video on veritasium's video on "the infinity pattern that never repeats" thank you
For the inabilty of information sharing through the whole rotating blackhole whitehole shenanigans, the most likely way we would get to confirm it would be someone coming into our universe from another one down (on that model). Ofc the issue there would then if we believed them, or would take them for a mad man's ramblings :D. Though if that happened, it would only be fair we ourselves sent someone "upwards" so the people living further up also get the chance to get the same knowledge.
dont the doppler effect need time and force to be in a straight line to the receiver ?
so in a black hole that the forces are "bent" you need to be in the "bent" path or will you see the same thing as we seen with quantum waves or other observations ?
That we need to be in the "path" to see the real other wise be are seeing object moving past us in other directions like wen you stand i front of a car you see the whole thing.
But if you look from the side true a ole in a plank it will only "blink" ?

47:35 - Doesn't that suggest a causal chain of some sort, as you see in Anathem? Each universe downstream can't communicate back but you can continue forward, exploring the strangeness ahead?
what if you sent a probe with a physical wire into the black hole? To relay data via said wire, like a guided torpedo?
The signal is "made of" electrons, so it will never pass. That is, assuming, you have a magical indestructible wire.
The wire will just get ripped apart. It would need a tensile strength high enough to allow its atoms to stay away from a black hole relatively faster than light.
Wait, this just occurred to me. I have been looking into this subject for a while. Wouldn't the fact that a Black hole has mass that changes shape with rotation imply that a wormhole can't actually occur?
Though, interstellar has practically no flaws in terms of physics. The only few were made because of the intiative of Cristopher Nolan, to make the movie more entertaining. The movie has the book "directors edition of interstellar", written by Kip Thorne with all formulas and explanations, you can take a look in your free time.
1 problem with the theory of Relativity & special relativity is it fails at the quantom level & 2 is that it disagrees with the standard model of particle physics. So we definitely are still close to a major breakthrough in quantom fields & gravity but just are yet to find the right stuff to make it clear to us.
Isn't the premiss of the TV series "SLIDERS" that the group of protagonists tries to return to their native universe?
From the diagram , it seems time mathematically cant seem to go backwards in time because it requires the ability to send information beyond the speed of light. Or bend space backwards and have your lightcone point backwards.
36:20 And your trajectory into/out of black hole/white hole determines your entrance location and universe you exist in?
It was very interesting that Veritassium put thiis out and then Dr. Becky put out a video about the Axis of Evil, which was related in that it raises questions about the shape of the universe. I'm not good at explaining, but I saw them as related lol. you might find that Dr. Becky video interesting.
correct me if I'm wrong. if you go to the Antiverse and go into the Antiblack hole can you go back? if gravity is flipped the black hole becomes the white hole and the white hole becomes the black hole
and one thing. if the anti-verse has the opposite time you just go back and forth into the black hole and so on and so forth so you can't go into the anti verse
I highly recommend checking out the 'Minecraft SCADA' channel. She has created a VERY NICE in-depth S.C.A.D.A. setup on minecraft with a mod called ComputerCraft to control and manage all her turbines, fission reactors, automatic fuel reprocessing, etc. Here is her setup showoff/trailer video title "ComputerCraft + Mekanism SCADA Beta Release"
14:45, IMHO, the interior of a black hole (within the Schwartzchild radius) doesn't a contain a singularity, but instead is a quantum particle an infinite energy well. This a physical realization of the quantum mechanical idea of the particle in a box.
And all along i thought that crossing the event horizon would make you disappear then return 7 years later as absolute evil with sharp needles sticking out of your head.
The map of infinite universes could simply be too large for us to gather knowledge to calculate outside our observable universe as well.
And maybe the signs of whiteholes are just the big bang making two more, then two more, in excess, exponentially growing, maybe even repeating most aspects with slight variations per dual branch created. If any variations, then that'd mean the field/plain we are on could be curved as well. Showing that time/space/light is impossible to cross, but nature says it should in some way. Maybe all at once for a new universe? Like a balloon or Bubble popping into a wider area. (more dense in smaller area, but overall more area covered if you include the gas or water in the balloon popping into differen't pieces and spreading gas/liquids everywhere. Entropy ect.)
ringularity cracks me up XD
Maybe I'm missing something, but isn't the "parallel" universe just our universe, but it appears there since we squashed cones into triangle? So if you would restore one more spacial dimension, and make graph 3d instead of 2d, our universe would be around the cone of black hole? There were some other transformations applied to the graph, so maybe they prohibit restoring of this dimension in this way though.
Edit: to clarify, I mean the first parallel universe, in non spinning black hole.
Seems pretty plausible to me. This is all so silly that I'd not be surprised if few people actually bothered to go through and check it all super carefully who knew what they were doing and actually transformed it to other projections etc.
I wonder what happens when electrons do eventually touch just from the force. (Like forcing 2 weak magnets to touch but obv much stronger lol) Is that what creates blackholes? When there is enough mass to make electrons or whatever particles to touch
Nuclear Engineer, can you please react to Radiacode gamma spectometer?

The best videoon veritasiums channel is the recent one on anolog cumputers
If it's an Anti-verse time would go backwards like he said, so you would be forced to go back, and infinity be stuck in a loop of going in and out of the singularity, right?
i like watching this one and its cool to see it from two people
The diagram reinforces my belief that the Big-Bang - as Neil Turok postulates - is a mirror. As a result, time would only run backwards from ours perspective in the parallel universe. From the perspective of the parallel universe, the white hole would be a black one and time would pass like in our universe. (By the way, the antimatter-puzzle would be solved)
How they would communicate from inside? There's no way.
Space is a huge milestone for humanity to conquer. Black holes are final boss
What if the diagram at 39:32 was circular, things go into the black hole from our universe and can get spit out into the parallel, and things from the parallel universe goes into the white hole and spit out into our universe but we are all going forward in the universe we happen to be in and can't see whats being sent out from the white holes behind us, so the parallel universes white hole would be what our universes black hole, and the parallel universes black hole is our white hole, idk how the math would work, that just something my brain thought of
I might have missed it but why can't the coordonate system be connected at 36:21. Why did they propose the idea of another universe instead of simply just the same one? So that our universe is connected to the singularity both left and right
so does that mean the singularity is absolute zero, aka when time stops, atoms and electrons stop moving. this can only occur at absolute zero. As far as I'm aware.
Hold on new theory, what if a white hole is actually just the big bang? Its depicted at the bottom of time And going through a blackhole sends you to a different universes big bang.
1:35 Would it be compressed?
I got a question though... When light gets absorbed by an atom and before it gets emitted again, what does the atom do?
I only know an electron will go to a different shell briefly and fall back while emitting that photon, but while in that higher energy state does the atom jiggle more?
Is it possible to shed this energy by bouncing into a different atom, preventing the photon from being emitted?
Yes and no.
Atomic collision in such a scenario would be rare (here on earth where we see photon emission from electron field changes) because of the shared repulsion between the two atoms, or more correctly, between their electron fields.
WERE they to collide, the energy could be transferred to the neighboring electron field, but that electron field would behave just as the original field and emit a photon when the electron dropped back to a lower energy level.
@@John-ir2zf Fascinating, I would have expected such repulsion to also cost some energy, hinting at the possibility that neither atoms would have sufficient energy to emit the photon, given that they need to be in discrete packages.
But nature probably has a law against that haha :P
@Yezpahr the repulsion effect is inherent. It just "is", and doesn't require any outside energy to exist or to perform its function.
It's a fundamental property.
The energy gained by the electron field has to go somewhere because the excited electrons are unstable in a higher energy state.
I would need to spend some time thinking it over, but ionic bonding could possibly occur if several electrons where raised to a higher energy state, and another element could "grab" on to those electrons and incorporate them in to its own electron field via an ionic bond. Not certain which elements would need to be involved though and the conditions the bonding would need to happen 🤷♂️
@@John-ir2zf Thanks for filling in the massive holes in my understanding.
I picked up tiny pieces of wrongthink over the years without realizing.
Example, I literally thought "energy's" could just flow over randomly to another type, seems to hold true most of the times.
Kinetic energy to heat, heat to light, light back to heat, so for a noob like me it wouldn't be a stretch to wrongly think kinetic energy was transferred in those moments of repulsion.
Nature's layers of complexion is baffling, thanks for lifting the veil a bit.
@@Yezpahr you are very welcome.
The thirst for knowledge, in some regards, is more noble than actually acquiring the knowledge.
Should react to pbs space time in the future
New background?
Ill try and do a quick summary of the geometry of the interior of a black hole.
The classic, "swirling drain" metric is appropriate for the approach TO the event horizon, and over it.
But, when you approach the singularity itself, at the bottom of the "swirling drain", you will encounter the inverse shape of that "swirling drain", the singularity will be sitting atop a increased curvature space. Think of the rebound in water when a drop falls in.
The only place to navigate past the event horizon, is near the bottom of the EH "swirling drain" where the space equals out between the EH "swirling drain" and the singularities "rising" curvature.
These are difficult ideas to grapple with, and even more difficult to explain coherently.....
well, is it possible that due to time dilation, that everything gets dumped into a singular instance at the beginning of time?
@gabusdeux that requires an expanded understanding of "time".
Time, as we think of it, is merely our experience of individual moments along a continuous "line of time".
In actuality, , the entire "line of time" already exists and we are merely seeing it play out as it does because of our narrow understanding.
We can not see the entire "line of time" at once because we are 3D organisms, with 3D comprehensive ability, in a 4D framework with time being the 4th dimension and all of that dimension occurs around us, all at once, everywhere.
Time dilation near a black holes event horizon, is a product of us struggling to comprehend the fact that "time" is not static or flowing in any direction, forward or backward.
if we were to step across the event horizon, what do you think "time dilation" would be like just on the other side ?
Would the dilation increase ? And what does that dilation increase look like, if, at the event horizon it reaches maximum and "time" stops for the reference frame of the people viewing it.
It will be a long time before most of humanity can shrug off that linear flow thinking and begin to see that "time" is irrelevant.
I know that's not an explanation of your question, but that's only because there is no explanation of your question when you understand that all of time exists at every moment that we experience....
The thumbnail looks like Einstein is playing with his saliva.
Hi. I just found your channel.
I do not like describing mass a curving space. I think there must be a simpler way to describe it. I like to think about space having its own kind of density. Mass accretions would be areas of low density space. Hell, I dont even totally buy the expanding universe idea either. When Hubble first found this warnings were given by others to not fall into the trap of thinking about it as a recessional velocity. I appears that way. Thats it.
I have a few questions you may or may not enjoy.
1.If a 10 solar mass star collapses to form a black hole what is the remnant mass and how big is the horizon?
I could work it out on my own but I am in hectic mode at the moment plus I would like to see the solutions of others as well.
2.Is it not likely that the permittivity and permeability of free space become severely altered under these conditions?
I look at black holes as possibly being recycling mechanisms in the universe. It may even be that at such intensities a complete coupling with either space or dark matter occurs. Maybe thats why dark matter halos form around galaxies. They just dont completely couple but cause sufficient perturbance to start the effect.
3. When 2 neutron stars collide I know heavier elements are formed from a portion of the debris. Could it not also be that Hydrogen is regenerated in these events since I am sure a decent number of free neutrons must escape as well? these would decay into protons, electrons and anti-electron neutrinos and eventually the protium would find another electron, right?
4. :Last one. I have already said I dont fully accept the current reason for the cosmic redshift but let me ask something.
We should be able to verify this once and for all if we can do this.
We have redshift at distance which is being attributed to expansion. We also have a distance/brightness relation.
At what distance should we be able to see the brightness shift as we are observing the supposed recession?
But they think neutrinos could be responsible for dark matter. So in that sense it has to be significant amounts of mass
Hey you might want to react to this guy who bought some nuclear testing equipment and made a synthesizer, the channel name is FLESH SIMULATOR he is a musician, its his last video, pretty dope. Ill try to post the link bellow.
Idk but when I hear schwarzschield I think about a force field.
I think white holes sound a lot like the big bang.
But we will probably never know.
React to "Can Nuclear Fallout Create Ghouls?" by Kyle Hill
Wow, just watched that video myself yesterday o.o
I've always wondered if speed was the answer to survive falling into a black hole. You get spaghettified because your lower body is being pulled faster than the top, but if you matched the "terminal velocity" of that gravitational pull before you entered, then your ship / body wouldn't be accelerated at a different rate and be pulled apart. Which I've been learned it's impossible for mass to travel at 100% the speed of light (if that's actually true) but if we could go 99.99999% that speed, i feel we could reach a point where the added pull wouldn't be too much and cause us to be pulled apart, just accelerate us that little bit more in one piece
No need for such efforts - just use a bigger black hole. The change in space time curvature, and thus tidal forces, will be more gentle and you could glide calmly through the event horizon. At least if you survive the from your perspective blue shifted radiation.
@@robertmartinu8803 that was another thought, as massive as black holes are, would it really even spaghettify us? I mean, you drop an ant on earth, and it doesnt hit terminal velocity the same as we do and splat on the ground. It kinda just glides down. Maybe that's more to do with air resistance given its tiny mass. However, still relative to the black hole, we would be teeny tiny. Although i believe the gravitational pull would be too strong to escape at a certain threshold, i wonder if our size relative to the BH would lessen the impact of the gravity trying to rip us apart.
@@kylewellman402 It's basically a matter of the ration of the distances between the center and your head vs center to your toes. If the ratio is 1:1 (an infinity black hole) everything of you feels the same gravity and accelerates at the same rate thus you feel nothing. For the supermassive black holes in the centers of galaxies that works out to be survivable. But a stellar mass black hole has its event horizon sitting much closer and you get a ratio different from 1. Your lower parts experience more gravity then the upper ones, because the latter ones are still further away - until the difference in acceleration causes forces that exeeds your tensile strength. Similar idea to the Roche limit, just more extreme.
@@robertmartinu8803 so our size relative to the size of the black hole does make a difference. We should be able to approach and enter a super massive without fear of getting pulled apart, but the little fellas the size of earth with a few solar masses are the ones that will rip our molecules apart lol
I still don't get why everybody alwas equates the formation of a black hole to the formation or automatic existence of a singularity. A black hole requires a high mass density but not an infinite one.
And wouldn't centrifugal forces alone balance gravity at some point in the star collapse way before reaching r=0?
A new video, nice!
Speaking of Alessandro Roussel from ScienceClic, I'd reaaaaaally encourage you to react to his videos on his channel !!
It's one of my favourite science vulgarisation channel on RUclips, and he does really great animations and simulations !
It's originally a French channel (it has english subtitles I believe), but he also had one voiced in English for some time now !

4:45 similar should be said about people who believe there is a diety who had a son come to save us from our sins.
The white hole seems to not really be mostly go into our world, the mass coming from a white hole seems mostly only go inside the black hole, and if something were to actually make it into our world, it would have to move at the speed of light in the infinite past.
Anything not moving at the speed of light within the white hole will with most likeliness just end up in the black hole.
They go ENTIRELY into the world. The whole top line only borders normal universes in the diagram, so you have to spend some time in a normal universe after being in a white hole before you can go back into a black hole again. Even at the bridge, it's a single point, no actual photon or anything can fit through it, like they said earlier, before the bridge pinches off.
Finally someone with a brain reacts to this video
Wouldn't a "white whole" look like a large star expelling/ejecting high metallicity material at a large velocity?
yes it does mean black sign/shield wich is irronic.
are you really spaghettified, if gravity stretches space, and not stretching you across a given space? You're still "occupying" the same amount of space right?
But at the same time, light can also be stretched when space stretches, and it changes the light so i guess we do become spaghetti.
