What is Absolute space and time?
'''Absolute space and time''' are concepts used by [[Aristotle]] and by [[Isaac Newton|Newton]]. They are still used in classical [[mechanics]]. Even in Newtonian mechanics, the notion of inertial [[frame of reference]] is used. The concepts of [[space]] and [[time]] were separate before [[special relativity]] theory, which connected the two. It showed both to be dependent upon the reference frame's motion. In [[Einstein]]'s theories, the ideas of absolute time and space were replaced by the idea of [[spacetime]] in [[special relativity]], and curved spacetime in [[general relativity]].<ref>Einstein, Albert 1922.
