It's my understanding that jupiter puts out twice as much heat as it recieves from the sun. I would like to ask: Is it possible that this may be becasue fusion does take place at a rate much much more rare then in the sun. Quantum mechanics and the laws of probabilites tells us that this might be a possibility - and it would explain why it is giving off so much heat. Maybe I'm wrong about my facts - or maybe I'm just wrong. I just thought it might have been a possibility.
