How the World Will End

Astronomer Chris Impey surveys the possible causes of earth's extinction. Whether it come from an asteroid or the sun's implosion, the rock we live on is by no means an eternal home.

Astronomer Chris Impey surveys the possible causes of earth's extinction. Whether it come from an asteroid or the sun's implosion, the rock we live on is by no means an eternal home. "What kind of catastrophe would it take to end the world? Astronomical intruders provide a potentially serious threat. Impacts can be caused by stray rubble from the Asteroid Belt and the rocky snowballs that travel in highly elliptical orbits in the comet cloud. There are many fewer large bits of debris than small bits, so the interval between large impacts is much longer than the interval between small impacts." Impey goes on to discuss less plausible scenarios—if only because a killer asteroid is more likely in the short term—like a hypernova to scorch the earth and the inevitable break down of the universe's most fundamental elements.

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.
