Time flies when you're learning super cool stuff. I'm Nate.

0:11.7

And I'm Callie. If you're dropping in for the first time

0:14.2

welcome to curiosity where we aim to blow your mind by helping you to grow your mind.

0:18.8

If you're a loyal listener, welcome back. Today you'll learn about how some cleaning products in your kitchen may be terrible for the environment

0:25.7

even though they're labeled green, hot blobs of iron playing games with Earth's magnetic field,

0:30.9

and how some far-out theories and physics predict there are infinite versions of you.

0:35.2

Without further ado, let's satisfy some curiosity.

I recently found myself in a bit of a quandary, Callie. Boy, that is a good word. Quandary? No,
