This video blows my mind every time I see it. The best part of this video is how simple they explain one of the most far out mind concepts. Until this video I mainly thought science was cool, but not any cooler than other subjects at school, actually I take that back, it was way cooler than math. But now I'm thinking that there is some seriously heady business going on in Science, and this is just the tip of the iceberg. Next step, time travel, bring it.
