I could easily rename this series "Things I found on Neil deGrasse Tyson's twitter."
This time it's an amazing interactive animation that shows you the scale of various things in the universe -- from the super duper tiny (the theoretical strings in string theory) to the super duper enormous (the entire universe!) and everything in between. It's absolutely fascinating, and it was created by a 14 year old student and his twin brother! It seriously puts my science fair projects to shame lol... Anyway, you can take a peek here! It's definitely the most informative, fun 15 minutes I've spent online recently.
