Dark Energy – Models| Dark Energy – Models |
In General > s.a. dark energy [holographic]; equation of state;
FLRW models; graviton; perfect fluids;
theory of cosmological acceleration.
* Possibilities: Cosmological
constant (w ≡ –1), quintessence, phantom energy (which may lead to big rip),
..., dynamical vacuum energy interacting with ordinary baryonic matter and dark matter.
* Chaplygin
gas: 2004, cmb peaks indicate 0 < r ≤ 1,
but supernovae indicate r > 1; > s.a. inflationary scenarios.
