Right now, billions of particles are popping in and out of existence in your pocket. That's not a metaphor — that's quantum mechanics. Inspired by a YouTube video from Anton Petrov about virtual particles turning into real matter, this week's thought experiment asks: what the if virtual particles were the size of badgers? What happens when those badgers start spontaneously appearing at faculty meetings and first dates? Turns out empty space is a lot busier than it looks!

Check out Anton Petrov's video that inspired this episode, "Actual Evidence of Virtual Particle Turning Into Real Matter!": https://youtu.be/VXdbffgTMVs?si=uL1hXd5ie4VfU2zq
