I think gravity based propulsion could be a part of it. Is the speed of light constant if someone can mess with the M in E=MC²? Would a piloted craft be unbound by inertia and make impossible maneuvers, accelerate from 0-1000 mph. with no problems if it had no mass?

I’m no physicist so your guess is as good as mine.

Gravity based propulsion would explain a few of the unexplainable things. And recent scientific discoveries surrounding gravity does more to support the possibility than disprove it.

Dr. Hal Puthoff and Dr. Eric Davis have written several papers detailing this exact concept. Essentially, they posit that all the phenomena observed can be explained through gravity-based propulsion. I’d have to find them, but they are published scientific papers.

Energy are rumored to come from zero-point energy, tech close indistinguishable it or stabilized Moscovium. Whatever it is, based on what we publicly know it’s not using any propulsion system we’re familiar with - So that rules out chemical rocketry from the start.

I agree that it seems impossible that any chemical reaction could generate the amount of energy required to warp spacetime.
