What would scale symmetry conserve? Entropy?
- scarmig 5y agoA relevant discussion that I'm digesting: https://physics.stackexchange.com/questions/2670/what-is-the-conserved-quantity-of-a-scale-invariant-universe https://physics.stackexchange.com/questions/2670/what-is-the...
- codethief 5y agoThe link doesn't seem very relevant. A scale-invariant or even conformally invariant universe is something completely different from some substance exhibiting (approximate[0]) conformal invariance during a phase transition. [0]: The paper from the article explicitly refers to "rotational invariance at large scales".
