      All matter in a black hole is crushed and compressed into a single point at the center called singularity which is infinitely small point-sized place. The matter will sit there for a very long time

      a singularity. somewhere where the rules of physic stop working.

      Hi Chaza, a very nice question indeed..As others have mentioned about singularity here, it cannot be proved by the present laws of physics. Black hole is very similar to a dying neutron star, which is also a very dense mass of accumulated debris achieved through a gravitational pull. Well, If you look at how nature works, if you have an inlet, there should be an outlet, nothing can accumulate infinitely, it has to release, same with neutron star which releases energy radiations identified as pulsars!

      I always thought that the black hole must have an outlet (there are some concept for wormholes, as per which if we pass through it, we will end up somewhere else, like time travel, but no proof again). So, i was very excited when two years back, i learned that scientists have been able to measure the radiations (X-ray and radiowaves) around the black holes, which they call black hole jets. This may be the answer to what lies beyond the black hole or what happens to all the energy accumulating inside a black hole.

      The link for the discovery is here: http://sci.esa.int/herschel/51482-herschel-gets-to-the-bottom-of-black-hole-jets/

      Using Einstein’s theories, you’ll calculate a spot that is infinitely dense and infinitely small: a hypothetical concept called a ‘singularity’.
