The Experience of Falling Into a Black Hole

[@MacEwanMouse]

I think the only way to escape the black hole would be to move a negative distance. Which doesn't exist. If moving positively in any direction means getting closer to the singularity, then moving closer to yourself then you already are is the only means of escape.

[@felixanderson8410]

That's actually kinda making sense... Would moving in a direction as time goes backwards count as going a negative distance?

to make it more concrete: once a an event predicted by a scientific theory becomes incongruent with what is 'supposed' to happen according to that theory (namely, the faster than light) than all the OTHER predictions made by that theory are also nullified (namely, what we know about black holes). In that respect, a faster-than-light ship could very well escape the black hole, we wouldn't know, we'd first have to develop theories of a universe where faster-than-light travel is possible.

[@legoboy1707]

I actually started to get a panic attack near the end. Great vid, but I'm confused. If the singularity is all around you, then how could you move towards it without moving away from it at the same time? Would you just be pulled apart?

[@JamesMcDowell]

at the event horizon you would be immediately obliterated. They ignored that part for the sake of explaining what would happen if you did go inside

[@DarkstarNovembr]

James McDowell No, you wouldn't. In the case of supermassive black holes the gravity gradient is shallow enough that the point at which light cannot escape is outside the point at which you would be spaghettified and die. So, if you try to enter a supermassive black hole's event horizon, you would be able to cross it and survive. You would still inevitably die later on as the gravity tears you apart, but you would at least cross the event horizon.

[@JamesMcDowell]

speghettification, true. i didn't think of that. but theoretically if you werent destroyed by the gradient, the event horizon is where you would be destroyed. Think of what is happening from the outside of the black hole. from an unaffected observer. as you went closer and closer, you would slow down, and as you became tangent to the event horizon, you would stop moving from their perspective. Time is asymptotic around a black hole, and it is why if you went inside, all trajectories away from it would be in the past. you would be below the asymptote. the event horizon is where no information can escape because conventional physics doesn't work in there.

[@DJHise]

Legoboy If you have a 2D paper representing space, then drawing straight lines on the surface of that paper seems to make sense for traveling in a given direction. Now imagine the 3D dimension is time. If you make a funnel in the 2D paper, any "straight" lines you draw will get bent in the new time direction more and more. In essence, it is bending spatial dimensions into the time dimension. As you hit a 90° angle, you are no longer traversing space, you are just traversing time. The only direction that leads back is in the time direction. Space has collapsed into a single point-- hence the name singularity. ...This rotation model also happens to be a fun alternative perspective of what the speed of light is. :D Take consider an arrow drawn out between perpendicular two axes: one space, one time. That is your trajectory in the spacetime. You can rotate that vector to either experience more space or experience more time. The light is the speed at which you are capable of experiencing changes in distance-- a speed in which you experience all possible distances. You contract the universe to an infinitely thin plane in the direction you are traveling. From your point of view, it takes you zero time to span the whole thing. That is when you manage to rotate completely in line with one axis. You can never rotate further than the 90°, because you can never trade any more of your time away, and you can never travel any farther away in distance.

[@ItCameFromTheSkyBeLo]

Legoboy That is an excellent question.

Fear of black holes can in no way and under no circumstances be considered "irrational".

[@minimash2485]

[@Zennistrad1]

Just wanted to point out that any FTL engine is by definition capable of traveling backwards in time, so you probably WOULD be able to escape.

[@ReapTheWhirlwind]

No, you wouldn't be able to escape. There is no space-time inside of a black hole and thus no plane of existence for your ship to travel through. That's why every direction led to the singularity.

[@SerIsaacofClarke]

***** You speak complete sense, but the general idea I think Bitsy is trying to describe is that a black hole's Event Horizon is defined as, essentially, being impossible to escape.In more scientific terms, as said in-video, outside of the event horizon are many points at which you can apply thrust to move away. Within the horizon, there are exactly zero. The main reason why this is true is because we don't know for sure, so our definitions are all we can go off of. Perhaps we CAN escape a horizon by some unforeseen factor, but we don't know because we can't try. *shrug* Everyone's right, I guess.

[@danielrhouck]

***** Faster than light is not the same type of thing as more horizontal than horizontal. If I "draw" a line in spacetime between two spacelike separated events, then that line describes a path that is faster than light, or from another perspective a path that goes backwards in time. Backwards in time? Where have I heard that phrase before? Oh yeah, the video I just watched included that phrase. It said that all paths out of the black hole go backwards in time. Maybe if I can go on a backwards-in-time path I can escape. Fortunately, I have an engine which can magically accelerate me FTL, which is equivalent to backwards in time. In fact, from my understanding, if I engage this engine to an FTL speed, there should be no way to go TOWARDS the singularity even if I wanted to do so. Is any part of my analysis wrong? If so, I would like to know.

[@MrKlomn]

If time no longer exists you die as you cross the event horizon because you are both at the epicenter of the black hole, and just crossing the event horizon. There is no way to escape except should time remotely exist from the black hole on a machine that triggers the deliverance of your FTL spaceship from non-existence. Which would turn your spaceship into one of Schrodinger's cats. Sorry my darlings I'm going to say the cat is dead.

[@TheRiverweasel09]

[@Tomtom18342]

because you're getting pulled towards the singularity due to gravity. the black hole is a deformity of space time (which is what the universe is made of), and once you cross the event horizon, space time itself curves into the blackhole, therefore the center of the black hole would appear to be everywhere at once, because "facing away" from the center is impossible, since space-time itself curves towards the center

would be pointing downwards, further into the the infinity of the singularity. Which means that whether you reach escape velocity or not wouldn't actually matter. The singularity would be all around you, and its gravitational force would only lead you one way: Further into the cosmic abyss.

[@LEARNdontHATE]

I was thinking the exact same thing, and I realised that as a result of accelerating to an infinitely high velocity, the breaching of the speed of light would (according to Einstien's Principles) likely tear you back in time, thus pulling you out of the singularity using the mode of time rather than space.

[@bingbongtheory]

A form of entanglement might potentially allow one to transmit data from inside to out using a probe. Not Quantum Entanglement, as that entanglement doesn't actually transmit data, but simply stores essentially a copy that reads the same when observed. An actual entanglement where information is transmitted instantly across any distance without having to go in between them could work. Another method could be Quantum leaping all of one's particles to an area outside the horizon, if control of such an overcharge could be possible.(not the tv show, the actual phenomenon)

[@spigotsandcogs]

Doesn't quite work like that. The event horizon is defined as the minimum distance at which light can orbit the singularity. If you somehow had engines that allowed you to go faster than light, you could easily orbit at below the event horizon. As to what you would see past the event horizon, I have no clue.

[@thornegarvin9865]

What you are referring to is called the photon sphere, the nearest stable orbit for photons. (E,G, Light) However, this is NOT the event horizon. At the photon sphere, those photons who have the appropriate electrical charge to repulse the black hole's corresponding charge will orbit. However, beyond the photon sphere, those who do not have the appropriate charge will be absorbed in. The event horizon references the area past which events cannot effect an outside observer. This is often based off of where photons can escape from a black hole, because photons are (Currently) the fastest thing known to humankind, so the area where light cannot reach outside observers is typically used as the event horizon. Another property of the photon sphere vs the event horizon is the effect of centrifugal force, the force that pushes rotating objects away from the middle, is not effected by the event horizon. However, at the photon sphere, centrifugal force is exactly 0, and past it, it becomes negative. (Note: this does not mean it becomes centripetal force) This effectively means that the photon sphere is close to the actual "point of no return", as the massive centrifugal forces generated by a black hole spinning at even a very small velocity would exponentially hurl you towards the singularity and death. These massive centrifugal forces are the same thing that keeps black holes from devouring galaxies in one gulp, as only objects with a high enough entry velocity to negate the centrifugal force and avoid being absorbed into the accretion disk or the equatorial jets of a black hole. An important thing to take note of is that the event horizon is quasi-defined by the fastest velocity humans know of, whereas the photon sphere is a constant. Note, all of my centrifugal force thinking is in non-inertial-reference frame newtonian. I'm sorry if relativity completely reks my math. Whew, that was a hefty wall of text.

[@JamesMcDowell]

Thorne Garvin oooooh rekt. This theoretical physics youtube comment battle is gettin juicy

[@flap459]

spigotsandcogs not quite (closer to being right than the other guy though). The photon sphere is the radius where stable circular motion requires an orbital velocity of c (the speed of light). If you point yourself at the black hole and move sideways at the speed of light you would just go round in circles (I think this is about 3x the event horizon). The event horizon is the radius at which your escape velocity is the speed of light, you would have to point yourself directly away from the black hole and go at the speed of light to get away.

[@JamesMcDowell]

the photon sphere doesn't really have much to do with this. the event horizon is where physics screws up. The photon sphere just marks the edge of where not even light can get out, but anything between the photon sphere and the event horizon is still theoretically intact. it just cant escape anymore

Nonsense aside this makes sense. Black holes, although we observe them as literal holes in the spacial plane, do exist, but at the same time do not. You see, gravity warps time, and is why if we were to live on Jupiter for one day then come back to earth, roughly 7 1/2 months would have passed. As you may know, Gravity increases with mass, and black holes are, to en extent, infinite mass. This "infinite" mass creates an extreme amount of gravity, as one could imagine. And if your putting pieces together, you'd understand that this extreme mass/gravity warps time so much that it flickers out of our position in the plane of time. So in legitimacy, black holes destroy themselves (and everything inside it) by warping back in time to a period where the holes is within itself and thus obliterates itself. But not really. As it warps back in time it doubles it's mass at that point in time by making it twice as dense. More gravity, more "time travel". Though we can't really call it that.

[@jeo6352]

Although black holes experience what we call time travel, it is actually warping time so much that it travels through time at a negative rate. This is when things get scary. Black hole se travel back in time, kind of, and create mass. That is by our science impossible, but it happens. This means that at one point, all of space and the infinite universe, will be one big mass. An infinite one. Where time will exist in such extremely random values, so that every second may be a year, or 12 centuries backwards. And eventually, it will grow and grow until, stop. This mass now holds the entire universe within itself. It bends time, and travels to a point in time that doesn't exist. Before creation. This mass is now gone. Quite literally, it has been deleted. The universe is now a void. One small particle however, did not follow the black hole. It is a small white speck, smaller than an electron. It's super heats in the void as all thermal energy is transferred to it. And it explodes.

[@jeo6352]

[@akigreus9424]

Inside the black hole the singularity is around you in the light falling in towards the black hole and at the event horizon heading towards it with infinite mass due to falling inwards at the speed of light. So the light would come from all around and as you slowly fall towards the center of the singularity it would get brighter a you would be "more in the equal distance away" from all the walls and eventually as you hit the center you are surrounded an equal non distance away by a wall of matter/light rushing towards you at light speed and thus having infinite mass. Not sure if I got this right but it seems the center is just the equal distance away from the singularity of the wall where the light crosses the speed of light.

[@Silverizael]

If you have engines that can boost your ship faster than the speed of light, then by definition, you can travel into the past with them, as going faster than the speed of light is getting somewhere before the light gets there. This is really what we mean by time in universal standards. Therefore, all he needs to do is point his ship in any direction and go faster than the speed of light. Then he gets out.

[@SelvesteDovregubben]

Did you even listen to what he said in the very beginning of the video? If not, then I strongly recommend you do so. But, to boil this down: The point is, that even if you DID possess a spaceship able to travel faster than light (which, as we know, is impossible), you still wouldn't be able to exit the black hole once you had passed the event horizon.

[@Shendue]

I'm not an expert. I just quoted a concept i've read from people that were supposedly informed on the matter. Anyway, i asked to my uncle out of curiosity about the story on this video (my uncle is the director of Physics department at the polytechnic university of Turin, Italy), and he said that the concept itself makes no sense, since no object can go hyperlight speed and, if it did, physics laws as we know them would be proved wrong and therefore the result would be unpredictable.

The way he is using general relativity in the sentence is not referring to General Relativity but rather the perception of the person of his position relative to his surroundings. He's taking stock of his relativity to what he sees around him. Hence he's looking at his general relativity.

[@Shendue]

BTW, the actual thing is a little more complex. If you accelerate to an infinitely high velocity you would also start having infinite mass, therefore you would become a black hole yourself. Maybe. Actually, it's pretty hard to tell, physics laws are all screwed up when it comes to black holes and hyperlight speed.

The concept of this video is legit. It starts with the hypothetical that it's changing one law of physics (speed of light universal limit), and maintaining another (cannot to escape event horizon). These conditions don't apply to real life; it's anyone's game to predict what the astronaut's observations will be. "Singularity closing around you" is as good a guess as any. In real life, though, if you pass the event horizon you will feel a well defined gravitational gradient away from singularity.

[@googleslocik]

no matter what you will do, what direction you move, or how fast you move, you will still go toward the center f black hole only way to escape is to time travel

[@Eelking1200]

You would be unable. You would either have to break the tether or leave it there.

[@shinjiku144]

Finally, just before you're about to cross the event horizon, -BUFFER VIDEO- ... I jumped.

[@scoreunder]

The event horizon is the point at which no light can escape. The idea that all the other directions lead "to the past" fails to make much sense, and relies on what amounted to an assumption by Einstein that light was the fastest possible thing in the universe.

I watched this after not sleeping for 36 hours and started vividly hallucinating...

[@Lyw1234567890]

Don't you get stretched when you enter a black hole though? Time slows down, and as you get closer to the event horizon or something you get stretched thinner and thinner?

[@Artificial-Insanity]

+Lisa Wang No. The reason you get stretched is the gravity gradient. Meaning that gravity applied to the end of and object closest to the source is higher than gravity applied to the end furthest away. This is true even on earth, your feet experience slightly higher gravity than your head if you're standing up. Since our planet's gravity is pretty low, it's not noticeable (except for objects in orbit compared to on the surface, there it does make a difference). Anyhow, the idea is that a black hole is so massive that it's gravity gradient is also much larger, i.e. the difference between what your feet experience vs your head is much larger. This is why you'd get stretched (and die ) as you get too close to a black hole. The larger the black hole though, the further the event horizon extends and thus there can be a zone within the event horizon where you're still far enough from the black hole that you don't get stretched,

[@vaeppur]

NewFormofSilence You're right about the stretching, but didn't mention what happens when you stretch. You technically "die" from having all the atoms ripped apart and "spaghettified" into it. But from a spectator's POV, you would seem to freeze in a stretched position due to the absence of time beyond that point. They haven't fully explained what is inside the black hole, they just call it "chaos" (i.e. storms, wild sounds, warped images, etc.) which sounds accurate bc it is impossible to prove what happens beyond that point, since nobody would make it back alive

[@AwesomeCrackDealer]

What the fuck man, that's creepy.

[@SamauraiRippeR]

Is that music from Star Trek First Contact?

[@AGrayPhantom]

I want this man to narrate my meaningless existence.

[@dragonnottin]

when life gives me lemons, I don't make lemonade. I'm mad like Cave Johnson, I got lemon grenades!

[@amihartz]

I could be mistaken, but couldn't you still escape the black hole with that magic engine? All directions point towards the black hole, except for the direction of the past. If you could break the speed of light, time dilation would actually cause time to flow backwards and you'd make it outside of the black hole before you even fell in in the first place. Going faster than light would take you backwards in the past. So technically you could still get out of the black hole if you just fired your engines.

[@polytimeInduction]

Amelia Hartman As someone who plays a lot of sandbox games, I just automatically assume that if you go fast enough into something, it'll just bounce you off of it with ridiculous amounts of force. So that might work as well. Probably not, but maybe.

[@amihartz]

Colin Smith idk but Neil DeGrasse Tyson said you could escape a black hole if you could go faster than the speed of light on StarTalk Radio.

[@Exphautaz]

Amelia Hartman he meant that as long as you weren't within the bloody thing, because if it gets close enough, even light, the fastest thing in all of existence that we know about, going at such an insanely high speed that nothing with any sort of mass at all is capable of getting close to such a speed whilst still following the laws of physics which allow it to exist. if the fastest, lightest thing, light, is incapable of going any faster, and it gets dragged screaming into a black hole, what makes people think it might be a good idea trying to send something made out of matter, steal, gold, titanium, a few other choice metals every now and again, all fairly heavy when compared to light, and try to escape the thing that is so powerful modern physics can't explain how it exists.

[@Exphautaz]

***** i wasn't advocating getting close to the bloody thingi was saying "hey that idea, of getting withing a place even close to being close enough to get stuck, is a fucking bad idea

[@amihartz]

Exphautaz But the hypothetical in the video is a hypothetical. No one's arguing that you can't go faster than the speed of light. The hypothetical is what if those laws were removed and you _could_ go faster than the speed of light. If you go faster than the speed of light, the equation says time would flow backwards, so you should be able to escape the black hole.

[@DOSAGEDUBZ]

you can slow down time you can't go backwards in time, most scientists consider it impossible because of paradoxes

[@freazeezy]

better then any creepy pasta I've ever read. can we get Benedict Cumberbatch to read this?

[@Nodrog666]

So, according to this video/post, if all trajectories that point away from the center of the black hole exist in the past, wouldn't the best method for escape to have a time machine? Collect your data and turn back the clock to before you entered the event horizon?

[@Numaticin]

***** Wait, WHAT? When did Christianity come into any of this?

[@NeonGreyscale]

***** Except you wouldn't be in the singularity just yet; you would be inside the black hole, having crossed the event horizon, and the singularity would be essentially surrounding you. If you hypothetically had a time machine or time travelling abilities... Well, to my knowledge, time as humans perceive it can't escape a black hole either, making time travel impossible, too. The only part of you that could escape would be your memory, which is abstract.

[@Nodrog666]

Mr. Diddlez Elaborate, please. How do you figure that would happen?

[@NeonGreyscale]

Nodrog666 I'm just going off of where the narrator left off- you've crossed the event horizon, you're getting closer to the singularity, but you're not there yet. I don't really know what you want me to elaborate. Nothing can escape a black hole once it's breached the event horizon.

[@Exarian]

That comment was the thing that took this story from creepy to terrifying.

[@Greyhaven7]

Is that music from Star Trek: The Next Generation? Sounds like the music used in the "Best of Both Worlds" episodes?

[@Shadow1295]

It does have a neccesity, it adds atmosphere to subject that most people would find boring or unnecessary to ever listen to if not for entertainment. Entertainment that is all the more hieghtened by the said unnecessary background noise that granted atmosphere as if you were almost in it. You see, most people could go there whole lives without even knowing about this if it weren't for the slight chance it could kill a few minutes of their drudging lives. Supported by the background noise.

[@malikrox]

I don't know what universe you come from where there are hadrons that size but where I come from hadrons are measured in micro- or picometres, I'm rather sure. I'm not actually a quantum physicist and am too lazy to look it up but that'd be my guess.

[@0mni42]

I find it supremely ironic that you use Star Trek music and sound effects, when Captain Janeway once found a literal CRACK in an event horizon...

[@TyWMayer]

Sooo trippy. Need to check out reddit more. Love thinking this stuff, you have a sub from me.
