This week, Justin and Doug explore some of the universe's most unanswerable questions such as: Why does time exist? Why can't we know the future? Is the universe finite or infinite? The dorks give answers to these questions and more!

Things are wrapped up with a throw-down featuring Swamp Thing vs. Groot.
