general relativity should be modified by an infinite series of additional terms in its equations. "In quantum gravity, one considers all corrections to the equations relating the energy and ...

Discover how Einstein’s theory of special relativity reshaped physics by linking space, time, mass, and energy in a universe governed by the speed of light. Albert Einstein's 1905 theory of ...

The Doppler equation used for sound calculations cannot be used in this situation. This is because galaxies are receding (moving away) at such high speeds that relativistic effects need to be ...
