Black holes...what actually happens.

what happens in a black hole. does time bend or dilate so much that it breaks? who knows... yout thoughts please :shrug:

In fact, not much is known about what happens in a black hole. Here's a great place to start: http://en.wikipedia.org/wiki/Black_hole

at a black hole, the laws of science break down.

Time becomes infinite and gravity becomes infinite. No light can even escape it. Hawking initially believed that the hole swallows any information and that nothing can escape. He recently withdrew his previous opinion and said that it does emit some type of radiation that is detectable.

Look this up in A Brief History of Time and a Briefer History of Time (updated edition) by Hawking, in the black hole chapters which is written for non-scientists and is relatively easy to understand. The books are readily available in most book stores.

The problem with black holes is that nobody even knows if they exist or not for sure. The whole concept is not fully developed as yet.

 

According to some theories, it is possible thet black holes spontaneously emit radiation and lose mass. This effect is inversely proportional to the mass of the black hole.

The blackhole is one of those things that because there is no hands-on scientific experimental data, one can only speculate based on math and imagination. Real data would narrow down the speculation field. Until then a blackhole can do anything one wants.

[Tormod]

What would be "hands-on" scientific data? There is plenty of observational evidence for black holes (mind you, I'm not claiming that this is the same as proof).

 

While I agree that we are not sure what a black hole is exactly, the same is true for a lot of things.

 

Here is one interesting report on black holes as seen with the Chandra x-ray telescope:

I could never grasp that...how can radiation escape from a black hole if nothing, not even radiation, can escape...

search 'hawking radiation' either on this site or google :eek_big:

From my learnings, space and time basically reaches an anomoly inside a black whole. Whilst you fall towards the hole, time slows down from the point of view of an outside observer. This means that your friend who saw you fall in will see your last aganising moments in the Universe spread out over infinity time.

 

So what happens to you? Scientists have found the answer using imaginary time, so they can penetrate the black whole to some degree and the answer isn't pretty. You fall in as normal and within a few split seconds your crushed into energy.
