Bubbles, Scams & CrashesBubbles

When prices float far above what things are worth

Scientists built a market where every trader knew what a share would pay. Prices still soared, then crashed. How?

  • Why knowing the value didn't help
  • What keeps a bubble floating

Why it matters

Every boom you'll live through, in homes, crypto or stocks, runs on one engine. Seeing it tells you where you stand.
