Summary

In this episode we will explore things you might notice about yourself or your pets, like why most people are right-handed or why cats love their scratching posts. Others ask about phenomena we experience every single day - like why the sky gets bright and then dark again. And one question tackles the biggest mystery of all: how the entire universe began, and what might have existed before it.
