Infinity sounds simple. It just means really, really big, right? But something weird happens when you try to do infinite things in a finite amount of time. Let's explore paradoxes, supertasks, and the bizarre mathematics that show how infinity is something far stranger than just a number.

Be Smart explores science questions you didn’t even know you wondered about. It is hosted and produced by Joe Hanson, PhD. We post new videos all the time, so please subscribe! If you enjoyed this video, hit the ‘like’ button, leave a comment, or watch another of our videos!
