Einstein asserted that the mass would have become infinite and/or created a black hole. But then came Alcubierre in 1994 who said it might be possible by contracting space in front of the ship and expanding space behind. They said this would violate laws of energy conservation, but the physicist Van Den Broeck theorized a way around this. So the solution may lie with Mr.Broeck. I haven't researched him at all; have any of you? Aside from that, do you think it will ever be possible for humans or any other species? Will we be capable of creating technology some day that can tamper with the sacred laws of gravity, quantum mechanics, relativity, energy, etc. that will allow us to explore some portion of our galaxy or beyond? This is an important question, because if the answer is no, then it could mean that the end of the human frontier.
