MOST of us would find living without electricity almost impossible, but in the early universe electric charge was practically nonexistent. It turns out that the electric charge of fundamental particles could have been close to zero when the universe was fractions of a second old. It's all because of the action of gravity - a discovery that, if confirmed, could help pave the way for a unified description of physical reality.
The standard model of particle physics does a great job of accounting for the fundamental particles of nature and three of the forces that act upon them - the weak and strong nuclear forces, and the electromagnetic force. Unfortunately, no one knows how to fit gravity into the model.
