Space-Time Symmetries

Space-time symmetries refer to the fundamental principles that govern the relationship between space and time in physics. They express how physical laws remain consistent regardless of changes in an object's position or orientation in space, or its state of motion. For instance, the laws of physics are the same whether you're standing still or moving at a constant speed. These symmetries help scientists understand the universe's structure, from the behavior of particles to the dynamics of galaxies, and are essential in formulating theories like relativity and quantum mechanics, which describe how the universe operates.
