If you haven't yet discovered the most awesome World Science Festival website, I highly recommend you put your evening plans on hold and spend a good few hours checking it out. One of the more recent videos is a three-minute explanation of the Holographic Principle -- the idea that a volume of space, or maybe even the entire universe, can be described as a holographic projection of information encoded elsewhere in a two-dimensional surrounding boundary.
Kind of puts a new spin on the old adage, "Life is elsewhere."
