Episode 21: Momentum: Why the Universe Won't Let You Change Direction
from The Polymath · host Achintya Krishnan
Why can't you just stop? Stop the bad habit. Leave the dead-end job. End the wrong relationship. You know what you should do. But you don't. Here's why: momentum. The same physics law that makes freight trains take three miles to stop makes your habits impossible to break. The same principle that makes rockets work makes career changes terrifying. In this episode, we're not teaching physics formulas—we're explaining why the universe has a bias, why it wants you to keep doing what you're already doing, and why changing direction is expensive as hell. We'll show you why startups die from lack of momentum, why Amazon redirected momentum instead of restarting, why astronauts drift when they throw tools, and why explosions are perfectly balanced even when they look like chaos. This isn't metaphor. Momentum is conserved—in physics and in life. Once you're moving, staying moving is easy. Starting from rest is brutal. And most people never escape because they don't understand they're fighting a law of physics. Now you do.
