I know relatively nothing about Science but i always love finding out about wierd stuff people have noticed about our universe and the way they try and make sense of it. Some of this stuff might be real complicated and some of it just fun, back to science class.
I watched this 2 part series a while back and really enjoyed it. You should probably watch the first one (everything) first but this was my favorite. I like how our understanding of science gets hazy at the biggest and smallest scales of things.
