Sep 9, 2024 · In physical theories prior to that of special relativity, mass and energy were viewed as distinct entities. Furthermore, the energy of a body at rest could be assigned an arbitrary value. In special relativity, however, the energy of a body at rest is determined to be mc 2.
Aug 23, 2024 · time dilation, in the theory of special relativity, the “slowing down” of a clock as determined by an observer who is in relative motion with respect to that clock. In special relativity, an observer in inertial (i.e., nonaccelerating) motion has a well-defined means of determining which events occur simultaneously with a given event.
His theory of special relativity was all about proving ideas that had never been confirmed by experiments. The whole thing revolved around the dual ideas that 1) the laws of physics are a universal constant in all systems, and apply equally everywhere in the universe, and 2) the speed of light in a vacuum is always the same.

This is as opposed the his General Theory of Relativity of 1916; this theory considers observers in any state of uniform motion including relative acceleration. It turns out that the general theory is also a theory of gravitation. Sometimes one hears that the Special Theory of Relativity says that all motion is relative. This is not quite true.
Relativity is two related theories: special relativity, which explains the relationship between space, time, mass, and energy; and general relativity, which describes how gravity fits into the mix. Albert Einstein proposed these theories starting in 1905. By the 1920s, they were widely accepted by physicists. Special relativity involves two key ...
Mar 14, 2021 · This second postulate explained the null result of the Michelson-Morley experiment. However, it was not this experimental result that led Einstein to the theory of special relativity; he deduced the Special Theory of Relativity from consideration of Maxwell’s equations of electromagnetism.
