Energy of electron states depends on:
n,l,m - in general
n,l - with rotational symmetry
n - for hydrogen atom with Coulomb potential
Why? Additional symmetry!

Energy of electron states depends on:
n,l,m - in general
n,l - with rotational symmetry
n - for hydrogen atom with Coulomb potential
Claim: due to additional symmetry!

Problems with Newton's gravity:
- instantaneous (what about c?)
- distance (according to whom?)

Einstein: the solution is General Relativity, with a spin-2 field (curved space-time).
Claim: alternative with spin-0 field, also compatible with equivalence principle
