Fall Into A Black Hole At The Speed Of Light With New Simulator

Quote from source:
Not too many of us have actually seen a black hole, but Thomas Müller, physics student, and Daniel Weiskopf, computer science professor, at the University of Stuttgart, have programmed a vision for us. With their simulation of a black hole in space, you can really imagine what it would be like to be in the pull of one.

A black hole occurs from the huge gravitational force of an exploding star. The force is so strong and dense that nothing can escape it, not even light. In fact, the enormous gravitational pull of the black hole would seem to displace the surrounding stars, creating dynamic and dramatic changes in, let’s say, a constellation. This effect is explained by the Schwarzchild black hole.

The Müller/Weiskopf simulation, detailed in the February 2010 issue of the American Journal of Physics, shows what happens to stars as they approach the black hole. In the video below, you can see the large stars of the constellation Orion seemingly split into two, mirror images of each other on opposite sides of the black hole.

I wish I could embed the videos but they are not you tube or google so I have no idea how to.

I thought this was cool and thought I would share it.

Any thoughts?

Whoa! That some freaky sheeet right there! Damn I hope I never get close to that thing yeah. Literally would take years of my life. Not to mention give me some funny lookin arms and legs.

not sure where i read it, probably thunderbolts.info, anyway, they were stating that black holes are a hypothesis only. and the idea has been bandied around for decades until its presumed to be factual. just like the official 911 story and the big bang theory.

I hear this all the time. They are a very strongly indicated feature of space/time. While not "proven" there is evidence. The theory of an atom is technically a hypothesis but we think that to be true.

the theory of black holes has strong evidence from physics and in mathematics behind it, as does the atom. I don't really understand why people choose to believe that black holes are not real.

black holes may exist, its just the fact that we havent found one yet. The closest thing weve found to a black hole was a pair of suns (or maybe just 1...) orbiting nothing, so by deduction, there is a blackhole there.

i think they are real though.

Electric universe proponents don't like the idea of black holes because they cause problems with the EU theory, but we have very good evidence for their existence. They are accepted as real because of this evidence, not because the idea has been "bandied around". Quite a few have been discovered.

The primary means of identifying a black hole is by the energy which is produced by matter before it falls beyond the event horizon. This energy signature is exactly what would be expected from theoretical models of black holes.

This simulation, although very cool, only considered the gravitational effect on light near the black hole. It ignores the gravitational effect on time. The deeper you get into a gravity well, the more your time appears to slow slow down relative to an observer outside the well (this effect has been experimentally verified to great accuracy many, many times).

Conversely, as you fall deeper into the gravity well and look out, time in the rest of the universe seems to be speeding up.

Here's where it gets important: When you reach the event horizon of a black hole, an outside observer would see time stop for you. From his point of view, you were accelerating towards the hole, then slowed down the closer to the event horizon you got. As you reached the event horizon, it would appear to the outside observer that you had stopped, frozen there for eternity, never crossing over (in fact, he could not actually see you at that point, because the light coming from you would be drastically Doppler-shifted (red-shift) as it climbed out of the gravity well towards him - In other words, your image faded from red to black).

From your point of view, falling into the black hole, you do not stop or even slow down. You accelerate all the way through the event horizon and beyond. As you look outward during your fall, time in the universe moves faster and faster. Supernovae would be barely discernable flashbulbs. Every star in the sky ages, swells-up to a red giant and dies. Others stars are born, live and die. Eventually, the remaining stellar fuel would become too rare and too dispersed for stars to form and the universe turns cold and dark for all eternity, until the protons themselves decay.

All of this you watch in the brief moments before you fall through the event horizon.

When you fall into a black hole, you watch the universe die.

That's just...
creepy.

That's utterly disturbing, seriously.

I don't think you would survive it though to have to worry about it. I also do not think that anyone would be able to watch you as you would look like spaghetti. I agree with your time scenario as just like you said it has verified many times, It's just that we would not be alive to witness such an event.

Awesome post though, you worded that very well. I always found it intriguing that black holes have an impact on time, just the fact that a singularity can do that an basically leave an empty void in our universe. To me black holes are another thing that we should be putting a ton of our most brilliant minds on as I think it would help to explain a lot of our universe.

Crap, now I have to go bed and I bet you I'll be thinking of the picture of watching the universe die.

Does that mean that any "object" falling into a black hole would take the entire lifespan of the universe to cross the event horizon?

This gave me some practice re-encoding video...

Adobe updated their flash codecs and every transcoded video that I've uploaded since updating my system ... Won't transcode properly on ATS's side.

ATS converts video (of any accepted common format) to flash upon upload...

Wull, it's broken. At least from what I can see. I'm going to clean up my video codecs and see if it's on my side.

Here are the embedded video's

That's true for a roughly stellar-mass black hole. The event horizon would be a sphere roughly 15km across and the tidal forces would spaghettify any object before it got close. However, the black holes found at the center of galaxies mass >1,000,000 suns. Their event horizons may be as large as the orbit of Venus or more. The tidal forces would be so gentle that you wouldn't feel them as you fell through the event horizon.

That is correct, for someone watching from the outside. Bizarre, isn't it? One of many reasons why relativity makes my brain hurt (though not as much as quantum mechanics). Remember, though, that the person falling though observes no such slow-down; he just falls right though while watching a spectacular light show.

I'm hypothesizing here, but I think you could map the mass distribution of a black hole as follows: The singularity at the center contains all of the mass that was within the event horizon when the stellar corpse collapsed to the point where the escape velocity became greater than the speed of light. The event horizon itself would create a shell of mass from everything falling in from the outside and, as you say, is taking the rest of Time to fall through. Further out, of course is the accretion disk, etc.

I believe it was Hawking who said-

"There are either holes in space, or holes in math".

One or the other.

I liked that line and always kept it in my head...with the hole I have there.

[edit on 11-2-2010 by Mr Mask]

Explanation: According to Hawkings equations you are simultaneously radiated away as Hawking radiation [wiki] AS you cross the event horizon!

Blackholes evaporate [wiki] OK!

Personal Disclosure: I don't believe a MASS singularity is even possible and I direct anybody who wants to argue that there is or to get a clue check out this skunkworks thread of mine....

Do Fermions decouple from the Higgs field? [ATS]

P.S. S&F!

Wouldn't the black hole that your falling into die along with everything else in the universe? If so then you'd never reach the singularity and just keep moving at light speed till you reach the end of the universe.

Somehow that doesn't make sense, cause that would imply all matter that gets sucked into black holes ends up at some future point in time when the universe is dead.

On the other hand if this was possible then all that energy send to the future from all the combined back holes in the universe could be a catalyst for a big bang and restart the universe all over again.

Yeah so that would mean that nothing could actually cross the event horizon. Also, wouldn't any matter be accelerated to a miniscule fraction below light speed making it incredibly heavy? Shouldn't the event horizon "shell" be almost infinitely massive? If it's going near light speed, where is it going? It can't cross the event horizon.

If it did, it would join the singularity in an instant and this end of universe light show would never be seen.

A lot of this stuff just doesn't seem to add up.

That was one fine post. Best I've read on ATS in yonks. Hats off to you, sir or ma'am.

Here, however, is a party-pooping physicist who disagrees with you. I'm not saying he's right, mind you: another physicist, Gregory Benford (who is also a novelist) wrote a story in which things happened much as you describe them.

[edit on 13/2/10 by Astyanax]

Excellent link, Astyanax! Very informative. It says that this time-speed-up does not occur for a non-rotating (i.e. Schwartzchild) black hole (which the video in the OP simulation depicts), but it does occur for rotating (i.e. Kerr) black holes (so I'm off the hook - kind of ).

I have trouble believing in Schwartzchild black holes. Every object we have observed in the universe rotates. Since angular momentum is conserved, as the dead stellar core contracts it spins faster - like a figure skater pulling her arms in. Thus a black hole should spin very fast.

I have read that (through a mechanism I don't recall) Kerr black hole lose their spin over time and become Schwartzchild black holes, but I think that may take a very long time.
