The most salient details are:
“Control of this higher dimensional space may bе а source of technological control оvеr the dark energy density and could ultimately play а role in the development of exotic propulsion technologies; specifically, а warp drive,” the authors write. “[T]rips to the planets within our own solar system would take hours rather than years, and journeys to local star system would be measured in weeks rather than hundreds of thousands of years.”
Those concepts include dark energy; general relativity, which Albert Einstein pioneered and predicted some bizarre-yet-real phenomena in the universe (like the warping of spacetime and gravitational waves); the Casimir effect, which describes the existence of a quantum “vacuum energy”; and M-theory — the idea that perhaps seven extra dimensions (which a warp drive could exploit) may be wrapped up in the four we’re familiar with, including time.
Opinion: We’re already there! We’re already harnessing the Casimir effect! It’s all in Flying Saucers.
As evidence I cite the Illinois UFO event of January 2000:
