I have a question concerning Universe and charges. Hello, First, just a brief clarification.
Protons carry positive charge, but neutrons are neutral, carrying no charge.
But, anyway, the universe does appear to be neutral overall. Most theories of the creation of the universe imply that there are equal numbers of protons and electrons. The answer appears to be that, as near as we can determine, the universe is electrically neutral. The electromagnetic force is so strong that if the universe had even a slight net charge, electric and magnetic fields should dominate the structure of our universe. And gravity, believe it or not, is a very weak force.
