幻影反弹：振荡宇宙学的新提议
The Phantom Bounce: A New Proposal for an Oscillating Cosmology
摘要：
一个振荡的宇宙通过一系列的膨胀和收缩循环。我们提出了一个模型，在该模型中，具有超负压（$p < - ρ$）的“幻影”能量迅速增长，并在后期膨胀阶段占主导地位。宇宙的能量密度如此之大，以至于量子引力的影响在每次膨胀（或收缩）的开始和结束都很重要。这种反弹可能是由对控制宇宙膨胀的弗里德曼方程的高能修改引起的，这使得宇宙学变得非奇异。经典的振荡宇宙的黑洞生产过剩是由于它们被幽灵能量破坏而解决的。
英文摘要：
An oscillating universe cycles through a series of expansions and contractions. We propose a model in which ``phantom'' energy with a supernegative pressure ($p < - ρ$) grows rapidly and dominates the late-time expanding phase. The universe's energy density is then 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 governing the expansion of the universe, which make the cosmology nonsingular. The classic black hole overproduction of oscillating universes is resolved due to their destruction by the phantom energy.
