Theory of interwoven space and time by Albert Einstein / From Wikipedia, the free encyclopedia
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 original treatment, the theory is based on two postulates:[p 1][1][2]
- 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.
