Escape Velocity and Black Holes

Every massive object in space has an escape velocity. Escape velocity is the minimum velocity an object must have in order to escape the gravitational strength of a particular planet or any large body in space.

Reaching this velocity is a very big challenge when dealing with space travel.  The more mass a body has, the more gravitational attraction it has; therefor
