Life Could Continue Forever—Just Not as We Know It
Katie Freese: Well with the dark energy most people do \r\nthink that the universe itself will exist indefinitely, but the other \r\nquestion is whether or not there can be life in the long term future. \r\nIn the standard explanation for the dark energy… I shouldn’t say \r\nstandard because it really is a big puzzle, but if there is a vacuum \r\nenergy that is constant in time it becomes more and more the driving \r\nforce of this expansion and causing evermore acceleration. In that \r\npicture then life dies out because you’ve basically… It’s perhaps \r\ncounter-intuitive, but as everything gets farther and farther apart you \r\ndo have this floor to the temperature of the universe set by the vacuum \r\nenergy. It’s a hocking temperature, so as you’re trying to operate \r\ncloser and closer to this cutoff from this vacuum energy any kind of \r\nlife form actually overheats, so as I said it is kind of \r\ncounter-intuitive, but you just can’t… It’s something you can’t avoid. \r\n Now on the other hand what we wrote in our paper is we were saying well\r\n but if it is not a constant vacuum energy, if it either time changing \r\nso that it is decreasing into the future or that you have this kind of \r\nCardassian Expansion that I was mentioning in either case then life \r\ncould actually continue because you don’t have this floor in the \r\ntemperature. In fact, instead it is also going down and so you can \r\ncontinue in clever ways to have life continue to exist.
\r\nQuestion: Will life continue to exist as it does here on Earth?
Katie Freese: No, no, not at all. Yeah, something \r\nreally very unpleasant from our point of view, so I have no idea, but \r\ncertainly not people, not… Things will get very, very spread out and \r\ndistant and cold and I’m talking about life in the sense of computation \r\nbeing able to continue.
If you think about our memories or our \r\nthoughts as a type of computation then is there some way you could have a\r\n molecular cloud, just like the kind I was talking about for the \r\nformation of stars where the different pieces of it communicate in some \r\nway and so you have intelligence of a completely different type than \r\nwhat we’re… than what we enjoy. So these bodies that we enjoy are not \r\ngoing to make it.

Molecular clouds that communicate with one another may continue to have a type of intelligence in the distant future, but "these bodies that we enjoy are not going to make it."

The Oxfam report prompted Anand Giridharadas to tweet: "Don't be Pinkered into everything's-getting-better complacency."
- A new report by Oxfam argues that wealth inequality is causing poverty and misery around the world.
- In the last year, the world's billionaires saw their wealth increase by 12%, while the poorest 3.8 billion people on the planet lost 11% of their wealth.
- The report prompted Anand Giridharadas to tweet: "Don't be Pinkered into everything's-getting-better complacency." We explain what Steven Pinker's got to do with it.
Moans, groans, and gripes release stress hormones in the brain.
Could you give up complaining for a whole month? That's the crux of this interesting piece by Jessica Hullinger over at Fast Company. Hullinger explores the reasons why humans are so predisposed to griping and why, despite these predispositions, we should all try to complain less. As for no complaining for a month, that was the goal for people enrolled in the Complaint Restraint project.
Participants sought to go the entirety of February without so much as a moan, groan, or bellyache.
- Facebook and Google began as companies with supposedly noble purposes.
- Creating a more connected world and indexing the world's information: what could be better than that?
- But pressure to return value to shareholders came at the expense of their own users.
