Absolute space and time
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.
