- TL;DR Summary
- Gravitational energy in de Sitter has EoS w=-1 (cosmological constant) and w=-1/3 (curvature energy in open or closed de Sitter). Is this just gravitational radiation, and how does this accord with EoS of photon radiation w=1/3?
Hi,
Gravitational energy in de Sitter has equation of state w=-1 (cosmological constant) and w=-1/3 (curvature energy in open or closed de Sitter). Is this just gravitational radiation, and how does this accord with the equation of state of photon radiation w=1/3?
Does this mean that densities of massless particles can have quite different EoS?
Thanks for answering!
