Physicist Richard Feynman explored the strangeness of quantum behavior through the famous "Two Slit Experiment," in which light is passed through two narrow slits and detected on a photographic plate. The expected result of passing light through two slits would be the appearance of two lines. Instead, one sees a series of lines of diminishing intensity on the plate. Some physicists, including C2C guest Dr. Fred Alan Wolf, believe this experiment may point to the existence of parallel universes.

A simplified version of the "Two Slit Experiment" can be conducted at home using a darkened room, an ordinary laser pointer, a piece of paper, and a wall. Read more about the Home Test to Prove Parallel Universes.
