Physics has had a lot of predictive power: economics hasn't. "Asteroids are incredibly powerful" is a physical statement, and a physical statement of causation that you can only make because physics is better-understood. With exceptions, physical statements have predictive power. With exceptions, economic statements don't. So that's why I say that causality in economics is not generally understood.
