LorentzSymmetry

Stephen Crowley edited this page Apr 20, 2023 · 1 revision

Lorentz symmetry is a fundamental symmetry in physics that arises from the principle of relativity, which states that the laws of physics should be the same for all observers moving at a constant velocity relative to one another. Specifically, Lorentz symmetry refers to the invariance of the laws of physics under transformations that mix space and time coordinates, known as Lorentz transformations. These transformations include rotations and boosts, which relate the coordinates of an event in one reference frame to those in another reference frame that is moving relative to the first frame.

Lorentz symmetry plays a crucial role in the theory of special relativity, which is the framework for describing the behavior of objects and events in the absence of gravitational forces. The postulate of Lorentz symmetry leads to some remarkable consequences, such as time dilation, length contraction, and the relativity of simultaneity. These effects have been confirmed experimentally to a high degree of precision, and they are essential for understanding the behavior of high-speed particles in particle accelerators and other contexts. Lorentz symmetry is also a key ingredient in many theories of fundamental physics, including the Standard Model of particle physics and theories of gravity such as general relativity.
