Thanks for your post!
I am not sure how the Star Trek drive works specifically,but I always thought that it was the same principle of constricting and expanding space?

Sorry if this has already been asked.
Could Einstein have been wrong about the whole thing, briefing his theories on what was 'thought' possible in his time?

If someone leaves at the speed of light from Earth to Proxima Centauri the trip would only be four years to the pilot of the craft while on Earth hundreds to thousands of years would have passed.
Time dilation and space flight
Time dilation would make it possible for passengers in a fast-moving vehicle to travel further into the future while aging very little, in that their great speed slows down the rate of passage of on-board time. That is, the ship's clock (and according to relativity, any human travelling with it) shows less elapsed time than the clocks of observers on Earth. For sufficiently high speeds the effect is dramatic. For example, one year of travel might correspond to ten years at home. Indeed, a constant 1 g acceleration would permit humans to travel as far as light has been able to travel since the big bang (some 13.7 billion light years) in one human lifetime. The space travellers could return to Earth billions of years in the future. A scenario based on this idea was presented in the novel Planet of the Apes by Pierre Boulle.
