Crashed UFO recovered by the US military 'distorted space and time,' leaving one investigator 'nauseous and disoriented' when he went in and discovered it was much larger inside than out, attorney for whistleblowers reveals
I think that is what the whole point of the Disclosure Project. If we accept that the UAP behave in the way that we are observing then the physics for it must exist. We can also not presume to know how that physics should behave as it is an unknown. A physicist might only be told part of the story and even then would not have a basis for any theory or believed as the physics is so far beyond us.
Having a technology and using it is different from understanding it and replicating. I imagine if you went back in time 200 years and told people about computers and tried to recreate it, it would be impossible.
This would change the world as we know it if we have it figured out but the technology could be used to either bring about a utopia or our extinction.
