There is no charge in the universe, and no energy. Mathematics is the key to understanding how something spring forth from this nothing, and is the thread from which the fabric of reality is woven.

What is the ultimate fabric of reality? My own position is quite clear: I am a materialist while being a scientist but a mathematical realist when being a speculator. Materialism, the view that the fundamental particles, including their agglomerations into atoms and molecules, together with the forces that bind them into interesting entities, are all that is necessary for all the properties of the world. There is nothing beyond these entities.
