What will happen if you go into a Black Hole?
When you get there it couldn't seem like a
particularly usual place, except that you will see strange optical distortions of the sky
around you from all the bending of light that go on. Before you get there, there
will be enormous tidal forces, due to the curvature of space time, Which will
through you and your space ship in many directions. The forces are so intense
that when they are acted upon you you will be stretched into a tiny string. But
as soon as you fall through, there's no escape.

If you watch the star will seem to collapse more and more
slowly. This optical effect is caused by the paths of light rays. But what does
this have to do with physics? Physics deals with many topics including energy,
mass, velocity, gravity, light, etc., so basically every thing in the universe is
related to physics in some way!
