What happens to matter which gets sucked into black hole????

Inside a black hole there is no time.When there is no time matter ceases to exist for the observer.

If you were holding a stop watch, facing someone on Earth, and shining a flashlight at them as well, as you drifted closer to the black hole, time would slow and the light would become red-shifted (as viewed from Earth). As for you, the light would appear normal.. and while time is essentially slowing (as viewed from Earth) you wouldnt notice it. However, you would most likely be burned alive by the hot gasses around a blackhole long before you crossed the event horizon.

Matter will disintegrate before it reaches infinite mass and will add more to the mass of the blackhole. Blackholes are just concentrated mass focused in an object. The more massive an object is, the greater the gravity. There is no such thing as destruction of light. You have to kill the source in order to shut off the light. Light is something that cannot evolve by itself. It needs a matter and energy for it to be emitted.

See what a black hole is?It is a place in the universe from where nothing can escape.Time & space cease to exist.There we achieve the clothed singularity. What happens to a particle which falls in the Black Hole hole?Any object approaching Black hole if falls in the Black Hole will never escape from the Black Hole.What I think & know is that any particle approaching the black hole when crosses the Event Horizon never escape from the Black Hole & becomes a part of the black hole.You can see the time will stop passing for the particle.Before it falls in the Black Hole it emits a lot of energy forming the accretion disc. The matter never gets destroyed as we all know energy+mass for the Universe is constant.It may be possible that inside the Black hole there is the conversion of matter to energy & vice cersa,but either of the 2 never gets destroyed.

Black hole is the densest elemant 1 cubic cm in black hole weighs around 10billion tons. and it has strong gravity(the reason for its dencity is its gravity) such that when light hits the black hole it can't reflect back.so we cant see black holes.
