Learn about Einstein's Theory of relativity from a 1923 film.
(even back then they knew the earth was round)
I have read the original paper on relativity, maybe two years ago. It is a great read, and I wonder if mathematics has found a way to bypass relativity to come up with absolutely accurate calculations.
Einstein's theory is 100 % correct, what do you mean by "bypass relativity" ?
It's not necessarily correct, and that's why it's not complete consensus in science that it is correct.
