I own the movie and basically form my religion around it. You have to be careful with this though, if you see the bonus features you will find that the creator is a bit wacky in the head (seriously.. she thinks she can talk with some guy that lived several hundred years ago), but all the information contained in the movie is legit. You also need a basic understanding of Physics to really know what they are talking about without having to rewind it a couple of times.

My favorite concept is that a person can actually walk through a wall, but it would take the entire world an infinite amount of time trying to walk through walls for that improbability to occur.
