NASA Scientist Explains the Grim Details of the End of the World; See Him Sunday

This is the future of our planet.This is the future of our planet.

Doomsday — the end of planet Earth — is alarmingly near, says NASA planetologist Chris McKay. But before you start calling up loved ones and stockpiling canned food, it's worth noting that for planetologists, time works on the scale of millions and billions of years. So yes, doomsday is coming, but McKay schedules it for 500 million years from now.

McKay will explain the end of the world Sunday at the Roxie Theater, along with UC Santa Cruz astrophysicist Greg Laughlin. The free event is organized by Wonderfest, an organization self-described as “the Bay Area Beacon of Science.”

So what's going to happen to planet earth 500 million years from now?
