Relativistic invariance refers to the principle that the laws of physics remain the same for all observers, regardless of their relative motion. This concept is fundamental in understanding how measurements of physical quantities such as time, length, and mass change when moving at relativistic speeds. It underscores the idea that no particular frame of reference is preferred, and all inertial frames are equally valid for describing physical phenomena.
congrats on reading the definition of relativistic invariance. now let's actually learn it.
