Why is the sky blue?

Ever looked up on a random Tuesday and thought, “Damn... that's a nice shade of blue” while sipping lukewarm coffee and rethinking every decision you’ve ever made?

Today, we’re dragging that pretty blue blanket into the interrogation room cause we've been lied to!

This is Explain Like I’m Dense... we take the big, complicated questions about the world and give gloriously chaotic answers with zero shame and maximum sarcasm.
So buckle up, buttercup!
