Title: What If?
Author: Randall Munroe
Category: Science & Discovery

What happens if you pitch a baseball at 90% the speed of light? Randall Munroe's 'What If?' takes that playground question and shows you the real physics—where air molecules fuse in a thermonuclear explosion, vaporizing the batter and leveling the stadium.

This episode walks through Munroe's most memorable answers: the baseball that becomes a nuclear bomb, the Earth suddenly stopping and flinging everything east at a thousand miles per hour, the global jump that barely moves the planet but crushes everyone into a deadly crowd, the mole of moles suffocating in their own heat, the impossible lightsaber that would burn your arm off, and the selfie with a black hole that stretches you into spaghetti. Each answer uses serious science to reveal just how wild the universe is.

If you love asking random what-ifs or want to see physics in its most entertaining form, this episode is for you. The takeaway is that asking silly questions with rigorous thinking is one of the most powerful ways to learn and appreciate the world around us.
