DOE Explains...Relativity | Department of Energy
WEBRelativity 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 ideas.
