This theory has probably already been raised on sciforums before... (actually I raised it years ago when this used to be the Alberta UFO research institute, and again when it was Exosci)
However, since certain people have claimed that interstellar travel is NOT possible, I will submit it again.

We may never have the means reach the speeds needed for realistic interstellar travel, but it IS possible...
Expand a gravitational field in front of an object, and weaken it behind. The force exerted by the stronger field will pull the object toward it.
Here is a simple experiment:
Stretch a sheet of cloth tight, and drop a heavy item in the center...this will create a well (if this were space, it would be known as a gravity well). Now drop a marble or ball bearing on the cloth. It will roll toward, and into the well created by the heavy object.
This illistrates the principle nicely.
