Star Trek Here We Come! (Maybe)
Some physicists disagree and believe that it may be possible to create what is in effect a Warp Drive that would allow starships to make a transit between two points in space at a speed faster than light, and they will do it without actually moving. The theory and its math was worked out by a Mexican physicist named Miguel Alcubierre and its called the Alcubierre Drive.

The ship itself would not actually move in an absolute sense (though it would in a practical sense.) What would happen is that space behind the ship would somehow (and that's the hard part!) be artificially expanded in size while the space ahead of it is contracted thus causing the space containing the ship to move at a speed faster than light. It would be comparable to you moving by causing the ground beneath your feet to move while you actually stood still. Is it possible? Time will tell. I am intrigued, but like the Space Elevator it seems like an idea that still needs to be proved and not just so much talk. Let's say I'm intrigued but not ready to invest.
Now we are not talking about going to Alpha Centauri next year or even in the next decade. There are enormous, possibly even insurmountable, technical problems to solve and questions to answer. Part of the problem is that initial studies reveal that the energy required to expand and shrink space are well beyond our total energy production or anything we envision for quite a while.
It will be centuries before we build a "warp engine." But consider this: a mere two centuries ago the moon was considered beyond any possible human reach. Now we are talking not only about going back to the moon, but even going to Mars and beyond. Consider that flight by a heavier-than-air machine was considered impossible until the Wright Brothers actually did it. In the 1700s some scientists believed that a human would die if he moved faster than 40 mph because the pressure from the air going into the face and into the nose would prevent a man from breathing out so he would suffocate.
One way or the other, unless our Lord returns, we won't be around to see it.
