Lorentz Group

The Lorentz Group is a mathematical framework that describes how the laws of physics, particularly those of special relativity, stay the same for observers moving at different velocities. It encompasses transformations like rotations and boosts (changes in velocity) that relate different inertial frames. Essentially, it ensures that measurements of space and time are consistent, no matter how fast someone is moving, preserving the speed of light and the form of physical laws across all inertial observers.
