Local Lorentz Invariance

Local Lorentz invariance is a principle in physics stating that the laws of physics are the same for observers in any local, non-accelerating frame of reference, regardless of their constant velocity. Essentially, it means that if you are in a small enough region of space and moving at a steady speed, the physical experiments you perform will yield the same results as someone else in a different, but similarly moving, place. This concept underpins Einstein’s theory of relativity, ensuring that speed of light and physical laws hold true locally, no matter how or where you are moving.
