How can it be related to frame-dragging? Every example of frame-dragging (aka "gravitoelectromagnetic induction" in the lingo of the linearized equations) that I've ever seen invokes mass-energy in motion - whether it's mass-energy in rotation or in linear motion, a proximal body gets dragged along with it. But there's always mass-energy in motion. The Alcubierre metric on the other hand is a static field configuration. That seems to bar any frame-dragging effects. Or are you saying that the field itself has an intrinsic momentum that drags the reference frame toward the destination? It's hard to see how that could be possible without mass-energy in motion relative to the ship frame....but then again a lot about GR seems counterintuitive until the fine points are explained clearly.
My limited experience with the Alien Scientist has been very disappointing. I think he has a B.S. in physics, but I've never seen him do anything more complicated than a Fourier transform in his videos - I'd be stunned if he could solve (or even clearly explain) tensor calculus equations. I caught some mistakes in his analysis of the Moscovium debate, and when confronted with them, he just got angry and churlish like a conceited little boy. His ego is the size of Mt. Rushmore. So in addition to being a generally unpleasant person, I haven't seen him offer anything of real scientific value in any of his myriad videos - but he is quick to embrace every cranky "fringe physics" idea that comes along. In my experience he's little more than a B.S. in Physics who thinks that his undergrad degree makes him a god we should all blindly kneel before like General Zod.
