  The earth has stopped spinning. We are no longer moving at 1000 miles per hour (1670 kilometers per hour) at the equator. Our days and nights are each 6 months long. Oceans part and flood northern and southern cities; most of those around the center of the globe are airless and lifeless. A lucky few human nomads discover the "last place on earth" where they can live year-round, a tiny ocean settlement where humanity ekes out the rest of its days on a non-spinning earth.

A world where that natural aging process is sped up, so it takes place on a human scale. How long could our world -- and all of the things we've built -- survive a rapidly aging sun? Take a look into a terrifying future -- where our planet is eventually swallowed by the sun.
