“Its continuing mission: to explore strange new worlds, to seek out new life and new civilizations, to boldly go where no one has gone before.” -Star Trek, in many incarntions
When Star Trek debuted 50 years ago, we didn’t know that there would be regions of the Universe that were forever inaccessible to humanity, nor that there would be galaxies permanently unreachable to us, even if we managed to develop near-light-speed travel technology. Yet thanks to the existence and dominance of dark energy today, that’s exactly the case. The only workaround, it appears, would be to develop faster-than-light travel.
But with the physical possibility of the Alcubierre solution to General Relativity, which would enable warp drive, this might actually render these distant, unreachable regions someday traversable. Not only that, but a whole slew of other “physical impossibilities” would suddenly become possible, enabling us to perform acts that physics without warp travel would simply never allow.
