Gravity Actiol

The weak force is definitely pretty hot, but it's pretty weak. It can't heat anything up, so it leaves the universe kind of cold. In gravity, if two objects with positive mass and the same charge, they're both positive, then they attract each other, rather than repel. For electromagnetism, you say, well, electric charge tells you whether it feels the force or not. For gravity, it's mass. Mass is the charge for gravity.
