Jun 12, 2015 · When physicists talk about Einstein's equation they don't usually mean the famous E=mc2, but another formula, which encapsulates the celebrated general theory of relativity. Einstein published that theory a hundred years ago, in 1915. To celebrate its centenary we asked physicist David Tong of the University of Cambridge to explain what general ...

Formula for Relativity: According to the theory of relativity, the formula is: γ = 1 1−(v c√)2. Where γ is gamma a unitless quantity, and it is popular as a relativistic factor. V. the velocity in m per sec. C. speed of light (constant) and its value is 3 ×108ms−1. γ.
General relativity is Einstein's theory of gravity, in which gravitational forces are presented as a consequence of the curvature of spacetime. In general relativity, objects moving under gravitational attraction are merely flowing along the "paths of least resistance" in a curved, non-Euclidean space. The amount that spacetime curves depends on the matter and energy present in ...
Nov 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.
For example, the special theory of relativity tells us that measurements of length and time intervals are not the same in reference frames moving relative to one another. A particle might be observed to have a lifetime of 1.0 × 10 − 8 s 1.0 × 10 − 8 s in one reference frame, but a lifetime of 2.0 × 10 − 8 s 2.0 × 10 − 8 s in another ...
Apr 5, 2014 · In relativity theory, Einstein introduced mass as a new type of energy to the mix. Beforehand, the mass of something in kilograms was just a measure of how much stuff was present and how resistant ...
