# The Big Bang Theory

Episode 16 of Family Guy season 9 (S09E16), the 163rd Family Guy episode overall. Written by David A. Goodman and directed by Dominic Polcino. First broadcast on 8 May 2011.

## Story

Stewie works out that his own travels in time caused the Big Bang and so brought the universe into being. His rival Bertram sets out to use that fact, planning to go back and kill Leonardo da Vinci, an ancestor of Stewie, so that Stewie is never born. Since the killing would also undo the Big Bang and wipe out everything else, Stewie and Brian follow Bertram into the past to stop him.
