preface is nothing so essential to the understanding of reality as the essential nature of time. Einstien's theory of Relativity changed our notion of time radically replacing Newton's universal time with a flextime that is malleable like any physical object with no such thing as universality to it. What May be a billion years on one Spot of the universe May be a Hundred thousand years on another spot of the universe. Not only that,if introduced noveltes like time travel i.e. to travel backwards and forwards in time. the universe is thus reduced to a block universe with time more or less reduced to a fourth dimension of space.
