Wow. This is the best, most visual, explanation of the 10 dimensions (eleven if you count dimension 0) that encompass Everything with a capital E. Everything (with a capital E) is all possible timelines in all possible universes--the dimension that the super strings vibrate in.
When I was in High School, my outstanding geometry teacher (and dashiki wearing, former rocket scientist) Ed Murrell recommended that we read Flatland to help us to imagine the leap from 3 to 4 dimensions, and beyond. At the same time, I was obsessed with physics in general. I had been exposed to the very fine info-comic Einstein for Beginners, which was helping me to begin a lifelong struggle to grasp the interconnectedness of time, space and probability. Then in college, I read The Fourth Dimension by Rudy Rucker. And that really blew my mind.
But I guess the lasting impression of this journey is my continuing awe at the possibility of the universe (or should I say, universes). Just as Neanderthals probably thought fire was magic, this stuff seems absolutely fantastical, especially if you are, like me, a visual and tactile thinker. But this movie really gets it right. Stick with it, you'll be glad you did.
