Infinity is a pretty difficult concept for us to grasp. The world we live in is full of limitations, so the idea that something can go on and on, forever and ever, doesn't come naturally to us. And to make things even more confusing, some infinities can actually be bigger than others.

Huh? The term 'infinity' seems like it would equally apply to all situations where something never ends. But as the latest edition of Minute Physics illustrates, some infinities can actually be larger than others. For instance, the infinite numbers between zero and one (decimals) is actually considered to be larger than the infinite whole numbers (1,2,3,5, etc.) ascending upwards. Crazy. Given it's only Monday morning, we hope we haven't completely fried your brain already. [YouTube]
