Falling into a Black Hole
Should you be unfortunate (foolish) enough to enter a black
hole your demise would be nearly instantaneous in your reference frame.
First, you'd be pulled apart by intense tidal forces (the force on your feet
would be much stronger than that on your head). Then you'd be crushed
as you become part of the singularity at the center of the black hole.
Things would appear different to a distant observer. Time measured far away would appear to get slower and slower as you approach the Schwarzschild radius - the distant observer would be denied the thrill of actually seeing you disappear into the black hole because time "stops" at the event horizon.

Space - Time near a Black Hole
Imagine you have a sheet of stretchable fabric. The Sun placed on this sheet
causes a "bowl" to form. This is akin to a warp in space (in reality, the warp occurs in a
4th dimension). If an object has enough kinetic (orbital) energy, it can orbit the sun and
not fall in. Frictional losses of anything rolling around on fabric
would cause it to spiral in, but in Space, there is very little, if any, friction.
Higher density objects placed on the sheet increase the warping of the sheet.
A black hole is a body so dense, its mass so tightly bound, its surface gravity does not allow light to even escape. In this metaphor, it is like a tear in the space-time fabric.
