Phantom energy

Phantom energy

Phantom energy is a hypothetical form of dark energy with equation of state w < -1. If it exists, it could cause the expansion of the universe to accelerate so quickly that the Big Rip would occur.

One application of phantom energy in 2007 was to a cyclic model of the universe.
