Lorentz invariance is a fundamental symmetry of the laws of physics, stating that the laws are the same for all observers, regardless of their constant velocity relative to each other. It underpins the theory of Special Relativity and ensures the constancy of the speed of light in a vacuum for all inertial observers.

Special Relativity, formulated by Albert Einstein in 1905, revolutionized the understanding of space and time by introducing the idea that the laws of physics are the same for all non-accelerating observers and that the speed of light in a vacuum is constant regardless of the motion of the light source or observer. This theory fundamentally altered the concepts of simultaneity, length, and time, leading to groundbreaking implications such as time dilation and length contraction.

Special Relativity

The constancy of the speed of light is a fundamental postulate of Einstein's theory of relativity, stating that the speed of light in a vacuum is always measured to be approximately 299,792,458 meters per second, regardless of the motion of the source or observer. This principle leads to profound implications for our understanding of space and time, including time dilation and length contraction.
