Lorentz symmetry

Lorentz symmetry is a fundamental principle in physics stating that the laws of nature, especially those governing space and time, are the same for all observers moving at constant speeds relative to each other. It means that measurements of time, length, and other physical properties may change depending on motion, but the underlying physical laws remain unchanged. This symmetry underpins Einstein's special relativity and ensures that no particular frame of reference is special, allowing for the consistent description of how objects behave at high speeds close to the speed of light.
