Special relativity

Summary
In physics, the special theory of relativity, or special relativity for short, is a scientific theory of the relationship between space and time. In Albert Einstein's 1905 treatment, the theory is based on two postulates:

The laws of physics are invariant (identical) in all inertial frames of reference (that is, frames of reference with no acceleration).

The speed of light in vacuum is the same for all observers, regardless of the motion of light source or observer.

Origins and significance History of special relativity Special relativity was described by Albert Einstein in a paper published on 26 September 1905 titled "On the Electrodynamics of Moving Bodies". Maxwell's equations of electromagnetism appeared to be incompatible with Newtonian mechanics, and the Michelson–Morley null result failed to detect the Earth's motion against the hypothesized luminiferous aether. These led to the development of the Lorentz transformations, which
