To explain the acceleration of the cosmological expansion researchers have considered an unusual form of mass-energy generically called dark energy. Dark energy has a ratio of pressure over mass density which obeys w = p/ρ < −1/3. This form of mass-energy leads to accelerated expansion. An extrem...
