Q: Can time escape a black hole?

as far as i know the only thing that can escape a black hole is radiation which the hole emmits... nothing else, and time is simply a human understanding of events its an idea, not a physical thing so no time cannot escape

Matrix,

I need you to expand on your question. If you are getting at something esoteric, your question was too succinct.

thats like saying can pride, or happiness escape a black hole. just like those things, time has no real existance. its simply us humans' way of keeping track of our life. and the proof that time is simply somehting invented by humans to live better organized, look at leap year. if tiume was something that exists beyond a human understanding, wouldnt it be more accurate then to lose a day every 4 years?

time does not exist, so its not somehting that can be even sucked into a black hole!

New black hole theory I read about says it is a sphere rather than a "hole", it solved a problem that couldn't be explained with the "hole" theory.

time is not a thing that can "escape" something. But time does do freaky things around a black "hole" (yes it really is a sphere) such as slowing down to a crawl for you if you were lucky enough to fall into a black hole. although you wouldnt feel this cuz you would be ripped into tiny subatomic particles.

Hmm.. That gives me ideas.. Think about it, you are dumbed from your space ship into a black hole. You start moving faster and faster, eventually nearly with the speed of light. According to the theory of relativety, your mass should be almost 8 (turn 90 degrees right or left). When you eventually collide with the matter in the hole, shouldn't this cause a huge collision? Or would you be ripped into tiny pieces that do no damage at all?

One more question (that the modern science can't answer, but maybe you folks give it a shot ) : How does a graviton escape a blackhole?

actually i think that matter spinning into the black hole and colliding with other matter is what gives off the large amounts of radiation that we can detect. but it probably wouldnt do any kind of damage because you would be in little pieces.

as i understand it particles can escape a black hole because they are not normal matter, empty space is not really empty but contians a bunch of quantum fluctuations, which spit out elementary particle pairs which then disappear so fast we cannot percieve them directly. normally the energy difference caused by this pair of particles being created from nothing is not noticed because they exist for such a short period of time, but when they happen to form near the curved space of a black hole the pair can split and one falls into the black hole and the other escapes, this does not fuck up the energy balance because the particle that falls loses more energy than it took to create both pairs, this decreases the overall energy of the black hole

Umm.. segue, something doesn't fit in, or then I'm just an idiot. Could you explain that "empty space is not empty space" thingy? Vacuum doesn't have any matter or stuff. Maybe photons or some radiotion.. And photons are affected by the gravitation, even though their resting mass is 0, so therefore they are not normal mass or what?

I think I read somewhere that if you were to enter a black hole head-first, the top half of your body would start to move faster than your bottom half, and you would basically stretch all the way until you were in the whole. And as you entered the hole, since light and perception of time slows down greatly, you would be able to witness the history of the the universe from when you went into the hole to when the hole was first formed.

By the way, I'm a newbie here. Hello.

ok sam, i'll try to explain it better, this involves quantum mechanics working with the theory of relativity, and it tells us that space is not so empty as we thought it was, its filled with quantum fluctuations that spit out elementary particle pairs, we cannot see or measure these pairs, but we can measure something they affect, the rate of energy transfer between energy levels in atoms,so if we could see them we would need to look at space in incraments of time very very small, say may billions of a second, ok, in one of these incraments, the section of space we are looking at is empty, a vacume, ok so far?, ok now go to the next incrament of time, shit look at that two particles have appeared, freeze frame, ok, next incrament they are gone again, but others have replaced them, ok there is a universal "law" of energy that states that all energy is accounted for, that is what is created is desryoed, the energy level of the universe is balanced in other words, as you can see the appearence of the particles in "empty" space violates this rule, but because the time they exist is soo sooo small the energy difference is not observable. so as you can see quantum mechanics does indeed bend the ideas and laws of reletavity, do you need more explanation? let me know, here is a crazy idea though, when black holes are formed its by an object collasping into a single dense point, now the interesting thing is that the larger the object that collaspes is the less dense of a black hole it formes, if one were to think about the density it would take to form a black hole with a mass equal to the mass of the universe, you would find out it would need mass equal the mass of our current universe, so we may be living inside a black hole...

dont think about that shit and u wont be wasting ur time all wondering about it

Bliizzard, yes, it's waste of time, but it's extremely fun!

Segue, I think I somehow know what you mean. So everything is filled with these particles that appear only for a very small period of time? Have they found out why this happens or where do they come from? And is this somehow related to Hawking's theory of *damn, I cannot remember the name..*, anyhow the main idea was that a quantum has a higher probability of appearing (or any piece of matter, or the whole universe) there "where it is" than somewhere else?

Thanks, Segue, check out my post on the other black hole topic.

However, you could never attain that mass. The cosmic rays emitted perpendicular to the accretion disk will always keep you short of the eventuality.

yes that came from hawkings, hes the one who first proved that nothing can emit from a black hole, and then later proved himself wrong, so who knows if our current understandg is right, it might be disproved later, and nox can you explain, i dont know what a accretion disk is...
