Metaphysics of Materialism
Content: which was just fine for Einstein because his theory of relativity implied that time and space are relative to one's frame of reference. So we don't need the aether; just as well since we couldn't find it anyway! Among its other startling implications Einstein's theory equated matter and energy and, more relevant for our story, equated gravity and acceleration. As a sidebar his theory also implied that everything traveled at the same speed: the speed of light! One other important implication of Einstein's theory was the wave particle duality that led to quantum physics; a theory Einstein himself never felt comfortable with. In fact, his disagreement with it led him to say "God does not play dice with the universe." But in experiments there is always a small probability of making a mistake and it was due to one such mistake by two physicists, Davisson and Germer, which led to the uncertainty that Einstein didn't like.
