Mexico’s Tulum is one of the stops in an enticing Caribbean voyage with the Roaming Buffs. Guest speakers include NASA astronaut Steve Hawley, science-fiction writers David Brin and Robert J. Sawyer and four of CU’s top astronomy professors — Doug Duncan, Mike Dubson, Erica Ellingson and Nick Schneider.

It’s not the end-of-the-world cruise — Dec. 16-23

Four great CU professors join other world-class speakers to address a wide range of topics while we’re at sea, including spaceflight, astronomy, science fiction and the Mayan calendar. The trip starts in Miami before reaching an appropriate destination with a visit to the Mayan ruins in Tulum, Mexico, the day some believe the Mayan calendar predicts the end of the world.
