abstract:Mass in special relativity incorporates the general understandings from the concept of mass-energy equivalence. Added to this concept is an additional complication resulting from the fact that "mass" is defined in two different ways in special relativity: one way defines mass ("rest mass" or "invariant mass") as an invariant quantity which is the same for all observers in all reference frames; in the other definition, the measure of mass ("relativistic mass") is dependent on the velocity of the observer.
Einstein's specialrelativity theory that says energy equals mass times the speed of light squared underlies "pretty much everything in modern physics, " said John Ellis, a theoretical physicist at CERN who was not involved in the experiment.
