The video is complete click bait hokum. It's so laced with jargon and pseudo-science words that it's virtually incomprehensible, and I suspect that is the intention. From what I can decipher, the maker postulates some method of changing photons so that they interact with the strong and weak nuclear forces, and then using a "field" of these photons at extremely high frequencies to create a shield around a spacecraft that would isolate it from normal spacetime and, incidentally, protect the spacecraft from radiation and debris while it moves at extremely high velocities. It's complete nonsense, and only tosses around Alcubierre's name as a way to attract attention. It has nothing to do with Alcubierre's paper.
This type of thing just makes me angry. The guy is nothing more than a troll. New category - science troll.
