Kip Thorne

Kip Thorne is the Richard Feynman Professor of Theoretical Physics at the California Institute of Technology in Pasadena, and a good sport. He signed this autograph for the Keepers in 1992.

"As a theoretical physicist, Thorne is currently interested in the origin of classical space and time from the quantum foam of quantum gravitytheory, and in the issue of whether the laws of physics permit space and time to be multiply connected (can there exist classical, traversible wormholes, and ``time machines''?)."
