Eternal inflation predicts that time will end
arXiv:1009.4698 · doi:10.1103/PhysRevD.83.023525
Abstract
Present treatments of eternal inflation regulate infinities by imposing a geometric cutoff. We point out that some matter systems reach the cutoff in finite time. This implies a nonzero probability for a novel type of catastrophe. According to the most successful measure proposals, our galaxy is likely to encounter the cutoff within the next 5 billion years.
