Relativity Space

-


before einstein s work on relativistic physics, time , space viewed independent dimensions. einstein s discoveries showed due relativity of motion our space , time can mathematically combined 1 object–spacetime. turns out distances in space or in time separately not invariant respect lorentz coordinate transformations, distances in minkowski space-time along space-time intervals are—which justifies name.


in addition, time , space dimensions should not viewed equivalent in minkowski space-time. 1 can freely move in space not in time. thus, time , space coordinates treated differently both in special relativity (where time considered imaginary coordinate) , in general relativity (where different signs assigned time , space components of spacetime metric).


furthermore, in einstein s general theory of relativity, postulated space-time geometrically distorted- curved -near gravitationally significant masses.


one consequence of postulate, follows equations of general relativity, prediction of moving ripples of space-time, called gravitational waves. while indirect evidence these waves has been found (in motions of hulse–taylor binary system, example) experiments attempting directly measure these waves ongoing.
