re: #264 LudwigVanQuixote

And the answer to how heat gets from the Sun to the Earth is pretty simply. Light is a form of energy. So is heat. When light from the sun hits stuff, it can cause the stuff’s atoms and molecules to wiggle and jiggle (i.e. gain heat).

So yes heat flows from hot to cold… when you are talking about substances in thermal contact. Light on the other hand is perectly happy to cross a vacuum.

So it’s like Jello?//
