Just because Einsteins theory of relativity will never be “proven” doesn't make him a moron. His theory is highly useful in explaining and predicting physical phenomena and is more accurate than the theories it refined; Newton's theories of motion.
If something in science was determined to be “proven”, then when contradictory evidence arises, what is to be done with it?
Everything in science is accepted provisionally, awaiting conflicting or refining data.
That is simply how science works. Something that those who reject science and the scientific method are apparently unwilling to attempt to understand.
Gee. So many to choose from.
How about Einstein's theory that gravity/mass bends light?
It took several years, but that theory was absolutely proven.
No theory is ever proven
Har!!
