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.
