The phantom bounce: a new oscillating cosmology
Matthew G Brown1, Katherine Freese1 and William H Kinney2
Show affiliationsAn oscillating universe cycles through a series of expansions and contractions. We propose a model in which 'phantom' energy with p<−ρ grows rapidly and dominates the late-time expanding phase. The universe's energy density is so large that the effects of quantum gravity are important at both the beginning and the end of each expansion (or contraction). The bounce can be caused by high energy modifications to the Friedmann equation, which make the cosmology non-singular. The classic black hole overproduction of oscillating universes is resolved due to their destruction by the phantom energy.
