Hawking did this analysis in the first edition of A Brief History of Time - though he made a complete mess of it - and concluded that time will start going backwards when the universe stops expanding!
I remember back when I read this at university, I thought: Boltzman will be turning in his grave. I also remember immodestly thinking: here's a smart, famous scientist - and even spotty teenage I could see what a ridiculous argument he was making - in about two seconds.
When I re-read A Brief History of Time in college, I remember bemusedly noticing that Hawking's argument would be stronger if you reversed its conclusion.
A note to myself from 2009 claims that Hawking later dropped that argument. Can anyone substantiate that?
Less Wrong is a large community of very smart people with a wide spectrum of expertise, and I think relatively little of that value has been tapped.
Like my post The Best Textbooks on Every Subject, this is meant to be a community-driven post. The first goal is to identify topics the Less Wrong community would like to read more about. The second goal is to encourage Less Wrongers to write on those topics. (Respecting, of course, the implicit and fuzzy guidelines for what should be posted to Less Wrong.)
One problem is that those with expertise on a subject don't necessarily feel competent to write a front-page post on it. If that's the case, please comment here explaining that you might be able to write one of the requested posts, but you'd like a writing collaborator. We'll try to find you one.

I will regularly update the list of suggested Less Wrong posts, ranking them in descending order of votes (like this).
