I'm sorry, that was a super disappointing reveal.

"However, we would expect the centrifuge to gain mass (and hence generate an increasing gravitational field) as fluid spins up to relativistic speeds. Hello warp drive! Oh, and you’re welcome."

Congrats, E=mc², you've collected a large amount of energy in a small area and created a gravitational field. You've now reached the space travel and anti-gravity technology of a small rock.

Yes to me it doesn't any more realistic than Bob Lazar's story that he quotes, just more convoluted.

My understanding of a warp drive (Alcubierre drive) is that it contracts space in front of the ship while expanding space behind it. I don't understand how increasing a gravitational field locally is meant to achieve any of that.

In think the point was sightly different - roughly that as a particle approaches the speed of light, its 'inertial mass' approaches infinity (as it requires more energy to speed it up). Unfortunately this 'inertial mass' is unrelated to gravity.

A small rock near a larger rock, to be fair. Still not very effective.
