- This opens the possibility of a Big Rip, in which the expansion rate increases without bound until it reaches infinity at some finite time in the future.
- This is a fun idea to think about, but some observers took it too seriously, and began phrasing their limits in terms of how many years would have to pass before there would be a Big Rip.
