For the physicists are etc who work at aircraft and spacecraft bases, what are they working with for theory?

A well respected physicist by the name of Oleg Jefimenko refuted Einstein (calling general relativity unreliable) and said there’s such thing as antigravitational masses.

Is it possible this craft was Delta Force’s or some other high level part?

I believe strongly the public’s science in terms of physics is a cover up. They are covering up antigravity and some other things that I think the military is developing based on the fact Jefimenko proves it all to be possible and we have footage there.

Also, physicists who attack me openly call themselves marxists, it’s really weird. Not bring up political stuff because I don’t like that stuff and I know the military is one regardless of politics but this really stood out to me that all the scientists supporting Einstein and the standard mode are mostly marxists.

Big science is alienation of the worker. It’s like working at Walmart. The scientists tell us there’s no such thing as individual achievement anymore and everything is based on collective big data. That’s such bs. How is there no more individual achievements in science? They are literally enslaving with computers. Quantum is a cult. Literally a cult, it’s like religion.
