Blackhole is a little bit confusing topic for me.Can anybody tell me,whats the reason and principle behind it that it absorb all sort of matter and radiations and still not releasing out?
A black hole does not have infinite mass. It is a black hole because its size (radius) is very small for its mass.We know that the greater the mass of on object, the greater its gravitational field. Well, a black hole has infinite mass, so the escape velocity is greater than the speed of light.
Actually the matter approaches a certain part and then become frozen above the event horizon. The material is redshifted so far that it becomes impossible to observer it. It then becomes impossible to measure the mass distribution and the gravitational field becomes identical to the field that would result if all the matter was confined to a point.At one point, the gravitation of this remaining core becomes so high, that all atoms basically merge into 1 point , ...
why does the gravitational force suddenly become so strong inside the core? What changes inside the core during the supernova to make gravitational force rise?
How fast would it happen? This might determine how detectable such a wave might be.
