You linked to ... woo? Like, this is not even science. I asked for a mathematical explanation of how to utilize the more exotic invariants of momentum in nonrelativistic spacetime, voiced in terms of GR. If the GP is going to claim this drive is possible because momentum isn't conserved in GR, the least they could do is use GR to show what they mean?

It's a low bar, but it's there.
