Astronomy department chair, Varsity Show character and Bwog birthday party guest David Helfand will be giving a guided tour "to the edge of space and time" at the Guggenheim tonight.

Explains the museum's website:

"Light particles from the depths of space tell us how the history of the universe began, and most likely how it ends. Columbia University professor David Helfand provides a visual journey through the galaxies, revealing both our knowledge and our ignorance."

So if you're lucky enough not to have locked yourself in Butler tonight, Bwog recommends a self-revealing look at your own ignorance, narrated by Professor Helfand.
