What is gravity? Newton and Einstein provided distinct theories to answer this question. Newton told us gravity is a force, while Einstein taught us that gravity is not a force. But what does this really mean? In this video I explain the difference between "acceleration" and "force" by introducing the concept of "freefall" and "equivalence principle". I prove that gravity is actually a fake. All this explanation becomes the foundation of Einstein's theory of general relativity -- and all in only 5 minutes.
