What do you get when you add up every number from one to infinity? Obviously, if you stop this series at any point before infinity, it will produce a very large number. But if you use certain methods of summation that can apply to divergent series, you will get a non-infinite answer of -1/12. Wait, whaaaa? Laboratory testing has proved this conclusion, and physicists all over the world have come across the result in string theory equations. Watch the video below to hear an explanation of this mind-blowing concept.
