I've heard alot about how an extremely powerful gravitational force can distort space and time. I was wondering (hypothetically) if it is possible to distort space-time enough by focusing a somehow artificial gravitational field into a single tiny point to pop a hole in space-time and travel vast distances through the cosmos in very little time. Sort of like an artificial wormhole. I am not a physicist, but I'm guessing that would require generating a gravitational field powerfully equal to that of a black hole. Which is probably impossible. But if it were actually possible, human beings could travel to other galaxies, solar systems, in search for habitable, extra-solar planets to colonize, or perhaps search for extraterrestrial life.
