Theater & dance

"Copenhagen" at Austin Playhouse. Inspired by actual events, the Tony Award-winning "Copenhagen" revolves around a 1941 meeting between two brilliant physicists, Denmark's Niels Bohr and Germany’s Werner Heisenberg. The two men were longtime friends whose work together opened the way to the atomic bomb but who found themselves on opposite sides of World War II. The search for an unknowable truth forms the core of the Michael Frayn play staged by Austin Playhouse. 8 p.m. Thursday-Saturday, 5 p.m. Sunday, through April 28. $32-$36. 6001 Airport Blvd. austinplayhouse.com/copenhagen
