A black hole is a region where gravity is so strong that light cannot escape itself.

Black holes cannot be seen as they don't reflect any light.

The centre of black hole is called singularity - a point of infinite density i.e the space curvature extends to infinity.

First of all, you would see the strangest funhouse mirror in the universe. Matter isn't the only thing orbiting a black hole: Gravity is so strong near them that light can orbit too.
