The complete single-action Lagrangian of Inverted Hypersphere Cosmology is now live 🙌
Hey everyone,
After solid months of work condensing the whole series down, the final capstone paper is finally up.
The Complete Lagrangian of Inverted Hypersphere Cosmology
One single action on real projective four-space (RP⁴), where every single term is forced directly by the topology. Nothing added by hand.
The action is:
S_IHC = S_EH + S_Ψ + S_gauge + S_matter
This one equation recovers all seventeen zero-parameter predictions — dark energy, sound horizon, lepton masses, fine structure constant, GUT scale, strong-CP solution, everything.
I also ran the full Lagrangian through Cadabra2.
8 out of 8 core tests passed cleanly.

Very happy to finally have the whole framework under one action. Would love to hear your thoughts.
