What happens if some thing falls into black hole?

 We all know what are black holes in the universe. They are the remainings of a dead star in space.

Now why they are black? Black holes are having the huge gravity power such that they don't let even the light to pass through them.

If a matter absorbs all the visible light falls on it, they would look black in colour. Whereas if they reflect all the colours of visible light, they will be white in colour. 

According to Einstein theory of general relativity,  if a matter falls into the black hole,  it keeps falling down and down and down , to a central point where it literally gets crushed into a single point. 

Real things are not known to science yet. 

If would black holes allow light to pass through them, then they would be called transparent holes.  !!!! 

We can say black holes suck matters.
