Science fiction is only fiction until it is not. Space travel was once science fiction.

That’s true. And Einstein’s Theory of Relativity contained some wacky ideas. But Relativity was testable. As was Quantum Mechanics, etc.
But much the stuff physicists are working on today is not testable, period. For example, string theory might have a decent mathematical foundation. But even proponents of the theory admit it is not testable.
So it’s like saying there’s an invisible cow in the room. But because of the nature of the cow, it cannot be detected by any experiment. Then I would say there ain’t no cow.
By the way, I taught freshman college physics for awhile. Since I put great emphasis on lab work, my colleagues nicknamed me “the experimentalist”. They did not mean that as a compliment.
