Up until now what has been holding us back from trying this is that we thought the amount of energy required would be prohibitive. Harold White of Icarus Interstellar (an advanced propulsion theme lead for NASA's Engineering Directorate) has located the loopholes that exist in the math using an instrument called a “White-Juday Warp Field Interferometer”. "At [The Johnson Space Center] JSC, Eagleworks has initiated an interferometer test bed that will try to generate and detect a microscopic instance of a little warp bubble. Although this is just a tiny instance of the phenomena, it will be existence proof for the idea of perturbing space time." Says White. White’s recent work intimates that if we optimize the warp bubble thickness while at the same time oscillating the bubble intensity we can then reduce the stiffness of Spacetime.
And there are other benefits! "There are no tidal forces inside the bubble, no undue issues, and the proper acceleration is zero. When you turn the field on, everybody doesn’t go slamming against the bulkhead, which would be a very short and sad trip." While it might not make it as a ride at Great Adventure, it will make the trip to Alpha Centuri in about two weeks.
