You might think that 1 + 2 + 3 + 4 +5… (and on in to infinity) would equal a very big number. But what if someone told you that the sum of all natural numbers is actually *negative one-twelfth*!

That’s right, according to physicists, the following is true:

1 + 2 + 3 + 4 + 5 + (infinity) = -1/12

What? How? Huh? No way! This must be some kind of mathematical hocus pocus, right?

Not at all.

In fact, it’s a solution that physicists can not only prove on paper, but one they also have observed in the natural world.

Watch this fascinating video, as physicists explain why such a counter-intuitive answer is actually correct:

If you understood all of that, give yourself a gold star.
