Relativity theory, formulated by Albert Einstein in the early 20th century, revolutionized our understanding of space, time, and gravity. It consists of two major branches: special relativity and general relativity. Together, these theories have reshaped our perception of the fundamental nature of the universe. Special relativity, published by Einstein in 1905, introduced a new way of looking at the laws of physics in the absence of gravitational forces. It is built upon two postulates: the prin

Einstein's Theory of Relativity in a nutshell. He received the Nobel Prize in Phisics in 1921 for the photoelectric effect. In 1905, he formulated the Theory of Special Relativity : In a vacuum, the light propagates at constant speed, giving rise to time dilation and contractionoflength. As well as the famous equation of the mass/energy equivalence E = MC² Energy = mass M × speed of light c² . In 1916, he published the Theory of General Relativity . It describes the gravitational interaction as
