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.

The idea of a particle that races faster than light has long fascinated physicists. Known as the tachyon, it was originally ...

Source: Relativity Calculator. At 95% the speed of light, the Lorentz factor will be 3.2. Therefore, for an object moving at 95% the speed of light, time will slow down 3.2 times and the length of ...

A counterintuitive result from Einstein’s special theory of relativity has finally been verified more than 65 years after it was predicted. The prediction states that objects moving near the speed of ...

Einstein's theory of relativity revolutionized how we view time, space, gravity and spaceship headlights. ... Special relativity. Einstein's theory is divided into special and general relativity.

'Time dilation' predicted by Einstein confirmed by lithium ion experiment. Physicists have verified a key prediction of Albert Einstein’s special theory of relativity with unprecedented accuracy ...

Special relativity declares a similar law for all motion: The combined speed of any object's motion through space and its motion through time is always precisely equal to the speed of light.

This “time dilation” effect, which was predicted by Einstein in his special theory of relativity in 1905, has been verified many times — first to within 1% of predictions in an experiment by Herbert ...

Special relativity is best known for letting us know that, as a person's velocity increases, their perception of time slows down. It also creates an ...

The theory, which Einstein published in 1915, expanded the theory of special relativity that he had published 10 years earlier. Special relativity argued that space and time are inextricably ...
