ОДНОВРЕМЕННОСТЬ

Simultaneity

Coincidence in time of events separated in space. The classical picture of the world contained the concept of absolute time, single flow of time proceeding uniformly everywhere and consisting of instants, each of which ensues throughout space. The theory of relativity dislodged from the scientific picture of the world the absolute motion ascribed to ether and rejected the concept of absolute simultaneity.

Identification of the moments of time of two events has meaning when we examine events within the bounds of a definite frame of reference. Events simultaneous in one frame of reference will be non-simultaneous in others.
