Science Made Simple: What Is the Theory of Relativity?
WebNov 25, 2023 · What Is the Theory of Relativity? 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.

WebSep 12, 2022 · Relativity is the study of how observers in different reference frames measure the same event. Modern relativity is divided into two parts. Special relativity deals with observers in uniform (unaccelerated) motion, whereas general relativity includes accelerated relative motion and gravity.
