Definitions for "Absolute time and space"
In physics, the concept of absolute time and absolute space are hypothetical models in which time either runs at the same rate for all the observers in the universe or the rate of time of each observer can be scaled to the "absolute time" by multiplying the rate by a constant. Similarly the notion of absolute space says that space is an inert arena on which other physical phenomena take place. The space affects the other phenomena, but the space itself is not affected by those phenomena.
