Albert Einstein concluded in his later years that the past, present, and future all exist simultaneously in 1952, in his book Relativity. He believed there is no true division between past and future, there is rather a single existence. “…for us physicists believe the separation between past, present, and future is only an illusion, although a convincing one.” Einstein proved that time is relative, not absolute as Newton claimed.
Julian Barbour (born 1937) is a British physicist with research interests in quantum gravity and the history of science. His book The End of Time advances timeless physics: the controversial view that time, as we perceive it, does not exist as anything other than an illusion, and that a number of problems in physical theory arise from assuming that it does exist.
