How does time behave in a blackhole?

Answer 1

Very oddly.

Space and time are interconnected. A large mass will bend space slightly, resulting in gravity. If you can't picture space bending, imagine a trampoline that someone drew a grid (like graph paper) on. Imagine a bowling ball sitting on that sheet. Things fall towards the bowling ball, and have to do work to get away. Its a pretty good analogy of what's happening, even if it is two-dimensional.

Imagine what would happen if you drove a large metal spike into the sheet by placing the bowling ball on top of it. The tip of that spike represents the (extremely heavy) point-like singularity at the heart of the black hole. The local gravity corresponds to how curved a given part of the trampoline is, and right near the tip the trampoline fabric/space-time is practically vertical. Not even light can escape such attraction.

Curving of space is also equivalent to how much time slows down. If you watched someone fall towards the event horizon (circle around black hole where gravity is strong enough to pull light back in), they would appear to freeze in place and stop moving (visualize a fly in amber) because time is so slow. The unlucky astronaut's brain slows down too, and he sees the rest of the universe sped up to chipmunk speed even though it is progressing normally. He will have seen the external equivalent of billions of years of history in super-fast forward by the time he hits the singularity. All bets are off as to what he sees once he reaches the singularity: the equations stop producing answers that make sense. However, this is assuming he could survive the pull caused by the fact that the gravity/curvature near his feet is stronger than the gravity/curvature near his head, which would pull an approaching human in half.

Answer 2

They claim (Einstein's theory basically addresses the flaws in Newton's theory of Gravity) that time will "bend" same as light and other energy. But I dispute this and will let you know yesterday after I return from a blackhole tomorrow. Actually if you put it on a scale ratio, everything else is accelerated and compacted, so intheory time would be to. Whether or not it just comes out "the other side" as an energy stream or a "worm hole" is the big debate, maybe even a parallel universe or dimension. In any event it's unlikely any living thing that goes through it would survive.

Answer 3

Impossible to answer with certainty since it has never been measured and can't be. There are theories that suggest it slows down or speeds up or just stops. But none of these theories can be correct since time is an illusion created by man, measured by our life times and our planets revolution around our sun. So, time can't behave in a blackhole at all because there is no time.

Answer 4

The sunlight isn't almost dense adequate for that's Mass to act like a blackhole, neither will it ever be. the nearest it is going to ever come to a blackhole is growing a White Dwarf, they are extra or less a similar mass because the sunlight with that's density squashed all the way down to the size of round that of Earth. yet nevertheless a techniques from the density of a blackhole.

Answer 5

So far, quantum physicists don't know what happens to time inside a black hole. The generally accepted, hypothesis is that it would slow down as one crosses the event horizon and accelerates to the speed of light, and then into a singularity.

Incidentally, time WAS NOT invented by man - - only the scale in which it is measured!

There is speculation that there may, in fact, be a quanta of time as well. M-theory supports the proposition.

Hopefully, in the near future, these questions will be better understood. In 2007, a new particle accelerator is scheduled to come on-line where it is believed that ultramicroscopic black holes can be generated.

Answer 6

That is such a difficult question since we don't actually know what goes on inside of a blackhole. We don't know if it is a wormhole or if matter is just ripped apart. I think that time gets stretched out and 1 day would be 1000 years.

Answer 7

the density of mass causes gravity. General relativity says that gravity is the curvature of space-time. (like those pictures you see of a ball on a rubber sheet. The ball is a sun or something and the sheet is space-time. The sheet has to bend AROUND the ball just like space-time has to curve around a massive object. Of course this is much harder to imagine in 3D and with time as well.) The more dense something is the more space-time curves. As a black hole has infinite density space and time both curve into it. In other words to move forward in time at this point, you HAVE to move into the black hole. At this point, known as the event horizon, not even light can escape.
We also know through relativity that dense things can be seen as slowing down time. Take a space ship outside a black hole watching an astronaught go into it. The astronaut would experience time being normal to him, he would experience himself being pulled into the black hole and bing ripped to shreds and then crushed. not nice. But the space ship would see the astronaught get closer and closer to th event horizon, and slow down, getting slower and slower and never actually reaching it- essentially seeing time freeze. This is because the closer you are to the event horizon the longer light takes to get from the astronaught to the ship due to the effects of the black hole on light, until at the event horizon it never gets to the ship. That is how we can say that to us time in the black hole stands still. It's very wierd.

Answer 8

if u really want to understand it'll depend how old u are
if ur under 13 u probably wont get it
over you'll be good
technically time has slowed down to a point that time really is not moving inside a black hole
we calculate time by the relation of other items moving around us.
Therefore, the powerful gravitationally pull of the black hole slows time down to where it is stopped in the singularity.
however all of this is theoretical there is lots of research going into it right now
its a good subject :)

Answer 9

Time is always moving, its the yardstick measure of age. without time, there is no age. however, even time has to be dependant upon some other factor and that is why we have different day lengths on each planet. in a black hole, time does move, you would still grow old wouldn't you?

i'ld say it behaves normally. a second is no longer and no shorter on earth than it is on pluto.

Answer 10

Time is something that cannot be touchedand cannot be expressed. Time goes on and never waits for anyone. Time in the earth or time in the black hole, it is always the same. Actually we don't even know the actual time! We think the clock says the time but...that is not true.
