Building on my previous thread, I was recently thinking about how energy and time are related by Noether's theorem (and stress-energy tensor <-> spacetime) and was wondering what symmetry would have information as a conserved quantity?

I've been recently thinking about how the current base quantities of our unit system (mass, length, time) aren't really fundamental and was wondering what aspects of the world would be highlighted with a different set: •energy •spacetime interval •information

This thread reads a bit like Carlo Rovelli’s Order of Time I don’t get most of it, but sounds like you think E, “L”, and some tweak on action are it? If the symmetry associated with E is “L”, that leaves information kinda hanging… is there a symmetry there?
