Hi
Could you comment on Big Snap scenario briefly mentioned by Max Tegmark on page 12 (and I can't google more):
How unitary cosmology generalizes thermodynamics and solves the inflationary entropy problem
http://arxiv.org/abs/1108.3080
I understand that during the inflation the number of degrees of freedom per Hubble volume decreases, so life will be impossible. However, isn't it the same as "Big Chill" - cold empty dark universe?
Also, what's so special about gamma ray bursts?

life as we know it may eventually be destroyed in a "Big Snap" when the increasingly granular nature of space begins to alter our effective laws of particle physics, much like a rubber band cannot be stretched indefinitely before the granular nature of its atoms cause our continuum description of it to break down

Moreover, in the simplest scenarios where the number of observers is proportional to postinfationary volume, such Big Snap scenarios are already ruled out by dispersion measurements using gamma ray bursts.
