True, the problem is the energy required to extrapolate it to a manned spacecraft, but the experiment shows that the theory of a WARP propulsion is possible. NASA is currently experimenting with applying this system to nanobots to use them to explore the universe, that is to say, we are certainly centuries of an application in manned spacecraft, but this does not mean that the energy required may be affordable for nanoscale bots. Meanwhile I believe in Clarke’s first law
