What future technology will be needed for mankind to get to the stars?

I have a theory of using a stable Black Hole, now all of us know that a Black Hole has an escape velocity exceeding the Speed of Light so if we were able to capture a Black Hole (which is way off in the future, so if we had the Technology to capture a Black Hole will mean we have the technology exceeding the Universe making my theory redundant but ignore this) and continue to feed it, and use the escape Velocity to propel the Shuttle forward it will eliminate Fual usage and make the ship super fast. i think i may have heard this theory somewhere else but i think its very invetive and a possible scienerio though this is a theory.
