i'm thinking they learn how to jump universes and just keep jumping from the old ones to younger ones, younger ones that maybe they even create themselves.
so what iteration are we in if everything is infinite? /mindisblown

Also, I probably shouldn't worry about any single aspect of my or my family's life.

Physics has really validated that whole "All material things are impermanent" aspect of Buddhism, eh?

Yes, very cool video. I kind of lost interest after Earth was destroyed, but man how awesome would it be to live that long to see it happen.

She’d been told that childbirth was going to be painful. But as the hours wore on, nothing bothered her — even without an epidural. “I could feel that my body was changing, but it didn’t hurt me,” recalled the woman, Jo Cameron, who is now 71. She likened it to “a tickle.”...She also reported that eating Scotch bonnet chili peppers left only a “pleasant glow.”

It's amazing that she's survived to this point; pain in proper measure is your friend.

I wonder about the time scale in that video - not saying it's wrong, wtf do I know? - but I've generally seen estimates that the universe is approximately 14 billion years old and that all the stars will be extinguished by about 100 billion years. The times in the video are longer than that by many orders of magnitude.

It's a long time from a big fire to completely cool ashes. Haven't watched the video yet but huge time scales and the possible ends of the universe are so far out there that they don't even make my head hurt. I've been too a few of the astronomy on tap events and the ones about possible ends of the universe are hard to understand.

If you want to understand the presentations, you have to make sure you attend only those that are given by someone with a Britishy accent.

I think taking the 'on tap' part less seriously would help. I'm usually good for a couple beers at those

we watched that timelapse video and it was excellent
wish they would have included "when the plastics break down" though

also currently reading the walter isaacson book on einstein so timely

Multiple outlets are reporting on an upcoming journal article claiming to have identified a mass death deposit related to the K/T boundary and Chicxulub impact. The New Yorker has the most in-depth article.

Outstanding.

Swiss firm claims to have made a 1,000 Wh/kg Li battery, and to have done it using a safer inorganic electrolyte solution. As the article details, it's an extremely bold claim.
