Einstein’s theory of general relativity has made countless correct predictions and yet physicists are constantly trying to prove it wrong. Why? What would it be good for to prove Einstein wrong? And how could it be done? In this video I go through the most promising experiments that physicists currently work on which could prove Einstein wrong.
