The change that changes nothing (symmetry)

[Magical Realist]

Profound implications of the concept of symmetry in physics. The fact that you can move around anywhere in space and still not physically change means you have spatial symmetry. You could also exist at another time and not physically change either meaning you have time symmetry. Symmetry is when you can perform an operation on something and nothing changes about that thing. It sounds suspiciously like consciousness were it not for that darned quantum observer effect.
