What Would It Look Like To Fall Into a Black Hole?

CNETNate writes "A new video simulation developed by Andrew Hamilton and Gavin Polhemus of the University of Colorado, Boulder, on New Scientist today, shows what you might see on your way towards a black hole's crushing central singularity. Hamilton and Polhemus built a computer code based on the equations of Einstein's general theory of relativity, and the video produced allows the viewer to follow the fate of an imaginary observer on an orbit that swoops down into a giant black hole weighing 5 million times the mass of the sun, about the same size as the hole in the centre of our galaxy. The research could help physicists understand the apparently paradoxical fate of matter and energy in a black hole."

According to the TFA, the red grid marks the event horizon as the "falling" observer would see it. Later on, you see a white grid, which marks the event horizon as distant observers see it.

I would have assumed you would see a completely black grid on a completely black background.

Well, wouldn't you see the light coming in, assuming that the gravity hadn't torn your body to bits?

What I find interesting is the weird pattern of light that appeared towards the end.

Re:Huh?

[Creepy]

Maybe you'd interpret it as black space, but technically you would not see anything there since its gravity is too strong to let any light out and your eyes rely on reflected light off an object to see it. You would see light bent around the hole, and as you approached the hole this light would get more and more distorted, especially at the event horizon (at least according to the general relativity theory the sim was based on).

So basically, if you're staring directly at the hole, you'd see nothing (it would appear black, because no light is reflected). If you're staring around the edges or elsewhere, you'd see a distorted light warp effect.

Re:Huh?

[X0563511]

Black is the absence of light hitting our retina. So, yes, you would be seeing black space.

Re:Huh?

[Dread_ed]

Of course you see nothing facing in toward the black hole, but what if you turned around? :)

It sounded (from TFA) like the event horizon is actually subjective; that you'd never "hit" it from the point of view of an observer falling into the black hole.

Of course, what the Academician probably meant was "the pixels go a funny shape and then the world goes blue with big grey letters on it".

Re:What does it look like?

[digitalunity]

You wouldn't see anything. You would be long dead before you hit the event horizon from gravitational shearing and compression forces.

Re:What does it look like?

[fractoid]

I'm talking 'observer' in the theoretical sense, although as others pointed out elsewhere on this discussion, supermassive (center-of-galaxy class) black holes are big enough that at the event horizon the gravity gradient is still pretty small, definitely small enough to be survivable by a human in a ship.

So you could in theory observe all that freaky shit happening as you approach the event horizon. Then again you'd have somewhat of a hard time telling anyone outside the black hole about it...

"A code" in the lingo of the scientific programming community means "a computer program that simulates these equations in an expedient manner," i.e. there is more than one way to discretize and program the solution of the equations, but they have done it in one specific way. It is therefore "a computer code."

Black holes have an infinite radius

[MichaelSmith]

...and a finite circumference. An observer falling towards the singularity would feel the local gradient in the gravitational field increase as they fall, probably to the point where staying in one piece becomes a challenge. This would go on for a long time from their POV.

Re:Black holes have an infinite radius

[Creepy Crawler]

Infinite radius would assume that time and position in space is NOT granular.

If even time is granular, Tipler's Omega Point theory could not work.

Re:Black holes have an infinite radius

[ceoyoyo]

It would take a long time from your point of view, on the outside. It would happen pretty fast for the sap who fell in.

Re:Black holes have an infinite radius

[garlicbready]

This might be completely wrong

I always thought that if you could see the outside universe as you were falling in the outside would appear to be moving faster and faster (from an inside perspective) the closer you got towards the center of the singularity. (effectively skipping ahead into the future faster and faster)

since quite a lot of junk falls into a black hole especially over the period of the universe's lifetime, you'd probably see all sorts of large amounts of crap following in behind you at a tremendous speed (stars etc) until it got close enough to be affected by the same space time distortion, but never quite catching up to your point

from an outside perspective if you could see what was happening beyond the event horizon, the stuff falling in would appear to move slower and slower the closer it got towards the center never quite reaching the center point
which makes me wonder if someone falling into one of these things would actually reach the end of time itself a lot more quickly than everyone else on the outside (assuming there is such a thing)

Re:Black holes have an infinite radius

[Mozk]

I think you're right. I remember reading that there is no indication that you've crossed the event horizon and nothing appears to have happened, while to an observer, you'll slowly descend to the center yet never reach it, just like you said. The things happening in the video don't really make sense from what I've learned.

Re:Black holes have an infinite radius

[Creepy Crawler]

Time frames will approach infinity from the viewpoint of the external observer, as dictated by special relativity.

The big question is what exactly happens at the surface and inside a black hole. And it depends on what exactly the nature of space and time are, and how they fail.

We can make conjectures here, but the idea that there is something space-shattering happening there seems rather likely. The idea that a macro-figure Calabi-Yau shape that prevents the collapse past the event horizon seems probable, but more research needs to be done.

Re:Black holes have an infinite radius

[Kagura]

Nothing exciting happens at the event horizon. It's just the point at which you need infinite energy to leave the black hole's event horizon again. For very large black holes, such as that in the center of the Milky Way, a human can safely pass the event horizon and see what it looks like inside. Eventually, however, the human will be subjected to higher and higher tidal forces--but that has to do with the size of the black hole, not with the crossing of an event horizon.

Re:Black holes have an infinite radius

[Creepy Crawler]

I thought exciting things DID happen at the surface, namely the particle zoo that the quantum foam "contains". And if the entropy calculations are correct (which im sure they are), I'd like data on those perpendicular X-ray jets.

Re:Black holes have an infinite radius

[JohnFluxx]

so what about Hawking radiation? For the outsider observer, an unfed black hole is continually shrinking (albeit slowly) while the subject falls very slowly into it. So wouldn't the (very long living) observer see the black hole shrink faster than the subject falls into it? But the subject must also come to the same conclusion, and so see the black hole shrink very rapidly as he approached it.

Any flaws with my logic? :)

Re:Black holes have an infinite radius

[Ambitwistor]

It's hard to define "radius" in a Schwarzschild spacetime. Outside and up to the event horizon, the radial coordinate is defined indirectly by the surface area of a sphere, which is sqrt(area/4pi) and is finite. (The circumference is also finite.) However, the proper distance between points at two different radii is not equal to the difference of their radial coordinates.

Inside a black hole, you can't even define a radius this way, because spacetime inside the horizon is no longer static, and there's no unique geometric way to separate time and space to define what a "spherical spatial surface" means.

From the point of view of an infalling observer, they hit the singularity rather quickly. There is an exercise in Wald's textbook which shows that the maximum amount of time which can elapse before hitting the singularity is experienced by a freely falling observer, and (IIRC) is equal to pi*G*M/c^3 where M is the mass of the hole (G is the gravitational constant and c is the speed of light). That works out to be about 15 microseconds per solar mass. And that's the longest time you can experience. If you try to accelerate "away", you actually hit the singularity faster, according to your own proper time, due to time dilation effects.

Re:Black holes have an infinite radius

[Anonymous Coward]

This is described in the book Black Holes: A Traveler's Guide by Clifford A. Pickover

Re:Black holes have an infinite radius

[Ambitwistor]

The previous poster is right; there is no local experiment you can perform at the horizon to determine whether you're at the horizon. You can see a lot of radiation if you hover at the horizon, but that's because you're expending energy to hover. Polar X-ray jets have nothing to do with the horizon, "quantum foam", Hawking radiation, or black hole entropy: they're due to matter and magnetic fields outside of the black hole.

Re:Black holes have an infinite radius

[Anonymous Coward]

Congratulations, you've re-invented Zeno's Paradox.

Re:Black holes have an infinite radius

[Anonymous Coward]

would also assume that circumference is not finite since c = 2pi(r)

Re:Black holes have an infinite radius

[ceoyoyo]

I expect (but am not going to do the math) that everything works out once you include the idea that if the event horizon is retreating (the hole is shrinking) then the time dilation effect is also not constant for a particular distance from the centre of the hole.

Imagine an observer A who is falling towards a black hole at just the right speed to maintain position a certain distance from the event horizon. From the point of view of an outsider, B, because the event horizon is shrinking, A is approaching the singularity at a particular speed. B agrees that he is approaching the singularity, although, because of the time dilation, from his point of view he is approaching much more quickly than A measures.

I think the situation is identical whether the event horizon is shrinking or not. If it is shrinking, the severity of the time dilation shrinks with it. The only difference would be that the outside observer sees A falling in slightly faster, consistent with the time dilation at any given radius becoming less severe over time.

Re:Black holes have an infinite radius

[Gavin Polhemus]

We think that you just fall in; you don't see the Hawking radiation or the hole shrinking. Your path into the black hole ends at the singularity before you see much happen to the black hole.

In other words

[LordKaT]

Once you came near the event horizon (given current technology) you would more than likely be dead, so this is a pretty pointless video, but we were able to use up most of our grant money renting out the SGI rendering farm to produce this. Isn't it cool? Can we have more grant money to do more cool things like this?

Re:In other words

[R3d M3rcury]

True. On the other hand, if I stuck you on the surface of Titan, you'd be dead, too. So it's pretty pointless to envision the surface of Titan or send probes there or anything like that.

Re:In other words

[LordKaT]

Making cute videos and sending probes are two entirely different things. I'd rather see research money spent on research and not cutesy little videos of "what would you see?"

If you're going to go down that route, at least make it an HD production and pitch to the discovery Channel. That way your money would at least go to entertaining people and getting more of them interested in science.

Re:In other words

[AKAImBatman]

1. Reaching a black hole is not impossible with current technology, but it is beside the point.

2. This is a research tool intended to help physicists understand what happens to matter as it enters a black hole.

3. Using all your grant money to run on an SGI cluster is so... 1990s. This was probably rendered on a modern laptop. If the calculations really did turn out to be too computationally intensive for a modern personal computer (I wouldn't count on it), they would have bought time on one of the more modern Linux or Mac computing clusters.

4. "Cool" is not the purpose. If it was, there wouldn't be fun guide-lines left in the film. This is a research tool that happened to get passed on to NewScientist to share with anyone who might be interested.

Re:In other words

[DRJlaw]

Once you came near the event horizon (given current technology) you would more than likely be dead, so this is a pretty pointless video...

Pointless unless you've studied relativistic physics, in which case the video is a modernized version of the classic thought experiment "Einstein's Train.". Everyone involved would be pretty dead if the train was moving at speeds fast enough to introduce relativistic effects perceptable by the ordinary senses, yet the illustration aids in an understanding of the physics.

The article is quite clear:

That's where visualisations like this might just help. "Close to the singularity, it appears that the entire three-dimensional universe is being crushed into a two-dimensional surface," says Hamilton (see Our world may be a giant hologram). But whether it hints that a 2D view is more fundamental is not yet clear. "Does it have any profound significance? I don't know..."

The death of the hypothetical observer is irrelevant to the usefulness of the video.

Re:In other words

Figuring out the Riemann geometry for this was non-trivial and should be lauded not dismissed as some trivial "cutesy video".

After finding this website, I would say you are correct.

There is also a "Step by Step into a Black Hole" of similar images as the video in TFA. Worth looking at if this is an interest.

I also found a cool animation of a simulated "Flight through a Wormhole".

It all just seems basic animation. Cool, but nothing really ground breaking.

I imagine that the models used to base the animation on could have taken some resources.

Not necessarily. Supermassive black holes' radii are so large that gravitational shear is something you probably wouldn't even notice as you passed through the event horizon. Entire human generations on a planet or spaceship could potentially be born, live out their lives, and die naturally, all while within one of these monsters, before the effects of gravity were to tear them apart.

Re:In other words

[amRadioHed]

Depends on the size of the black hole. For a large black hole you would make it past the event horizon before the gravitational gradient is strong enough to tear you apart.

Re:In other words

[khellendros1984]

Spaghettification. Let me guess. I can see only two options: one -- due to the bizarre effects of the intense gravitational pull, and because we're entering a region of time and space where the laws of physics no longer apply, we all of us inexplicably develop an irresistible urge to consume vast amounts of a certain wheat-based Italian noodle conventionally served with Parmesan cheese; or two -- we, the crew, get turned into spaghetti.

An anonymous comment that relies upon particular assumptions that are forbidden by the nature of the scenario. Like a train traveling through a vacuum, so that the train isn't destroyed by atmospheric resistance and the external observer isn't killed by the shockwave -- but the vacuum can conduct lightning. Like a train traveling in a straight line at 0.77c, so that centriptal forces and acceleration are unnecessary -- a space train struck by lightning. Nevermind that you've missed the entire point, that the situation is hypothetical, yet assumed the existence of hypothetical technology that can accelerate at 9/8 m/s/s for a year in a vacuum. The first example is due to speed. The second example is due to an unaccounted for acceleration. Both kill. Pick that nit. Nitwit.

Can you explain that a bit better? I thought time dilation would shorten the "apparent" time for the person accelerating into the black hole. This site (http://jilawww.colorado.edu/~ajsh/insidebh/schw.html) has an apparent time of 16 seconds which is not exactly the life of the universe.

Well

[rob1980]

I'm sure it would suck.

Try this one and you'll REALLY see what it's like to fall into a black hole.

I remember seeing a couple of documentaries on this a while ago...

Not all that paradoxical

[Anonymous Coward]

Really, black holes emit energy in the form of gamma rays and who knows what else that we don't know about. They don't just absorb everything while never releasing any energy. So when you think about it they aren't all that different from other stuff in space except for the fact that they absorb light and other weird things.

I call it...

[samriel]

I call it a Hawking Hole.

I fell into a black hole once

So just like a piece of grit?

Kudos to the programmers...

...for doing it with a single code!

Duh

It would look black~

Re:Duh

[Anonymous Coward]

Yes, but how much more black could it look? The answer is none. None more black.

There is a grue here.

[Tetsujin]

You'll probably be eaten by a grue.

Defy this cruel fate! "Frotz" a Grue today!

I expected a different ending

[aarku]

Did anyone else expect the video to lead into this at the end? http://www.youtube.com/watch?v=wRhPM2wMzH8 Just checking.

Singularity?

[Anonymous Coward]

I don't get this, why do astrophysicists only use general relativity for their calculations. I thought a singularity was an infinitely dense point, something quantum physics rules out as impossible.

Re:Singularity?

[Gavin Polhemus]

We use general relativity until we get to the singularity. Then the video stops. Up until that point general relativity is fine.

Related work: Greg Egan's website

[uid8472]

Greg Egan's website has a little Java applet to visualise what happens to light around a black hole, dated 2001.

He's got a bunch of other fun stuff there, explaining/"demonstrating" the strange physics (real and theoretical) used in his books and stories.

Hope it is faster than real time

[flyingfsck]

Considering that a black hole is more massive than the sun, then it will take longer to fall into the black hole than for the earth to fall into the sun and the sun will go nova before the simulation ends...

Re:Hope it is faster than real time

[cowscows]

If there's some sort of sarcasm implied in your comment, then I don't get it. If you're making a serious comment, then you're making even less sense.

What a cliffhanger. Just when it gets interesting it stops! I hope "Falling into a Black Hole II - The Sequel" comes out soon.

Its just like Vegas

What happens in a black hole stays in the black hole.

What happens if a black hole falls into a black hole? Mayhem? New universe? Walmart?

Very black.

Don't go there without flashlight

[GNUThomson]

The real question is: What happens when you fall into black hole and turn on a flashlight there?

Re:Don't go there without flashlight

[maxwell demon]

Well, if you manage to switch it on before you die, it just shines until it's destroyed. But nobody from outside could see it.

AWESOME!!

[cfriedt]

AWESOME!!

Not true

[Ambitwistor]

Falling into a black hole does not allow you to see the end of the universe. (The FAQ I linked to discusses one case in which a perfectly symmetric, rotating vacuum black hole does experience infinite blueshift, but the existence of matter or quantum gravity effects very likely destroy that property of the black hole.)

As every physicist knows...

[He Who Waits]

...what happens in the singularity stays in the singularity.

Re:As every physicist knows...

[maxwell demon]

...what happens in the singularity stays in the singularity.

That's not always true. What happened in the big bang singularity indeed did spread throughout the whole universe.
