What Is Lorentz Symmetry? Understanding & Differences

[TheQuestionGuy14]

I'm curious to know what Lorentz symmetry is, and how it works. The wiki description is a bit too difficult for me to understand. And how does it differ from a computer's cubic symmetry? I understand that in cubic symmetry, the laws of physics or physical things look different depending on what direction you are looking at it from, so how does Lorentz symmetry differ?

Lorentz symmetry means that the laws of physics are the same regardless of orientation and speed.

In other words, you could take any measurement device and make a measurement on any physical system. Or you could rotate and/or boost the device and the system and get the same measurement.

Does everything in the universe eg. Stars, planets, cosmic rays etc. follow Lorentz symmetry then?

As far as we know right now.

Of course, tomorrow someone might report an experiment or observation that implies "Lorentz symmetry violation", and if it were confirmed, it would be a Really Big Deal.

Lorenrz symmetry only applies between objects having constant velocities, i.e. inertial observers.
