Question
How, if at all, would the physical universe be different if the proton's charge was very slightly larger in magnitude than the electron's charge?
Step 1
In the current universe, the charge of a proton is equal in magnitude but opposite in sign to the charge of an electron. This means that atoms, which are made up of protons, neutrons, and electrons, are electrically neutral overall. Show more…

How, if at all, would the physical universe be different if the proton were negatively charged and the electron were positively charged?
In what way or ways would the physical universe be different if protons were negatively charged and electrons were positively charged? Gravity would be a repulsive force instead of an attractive one. The value of the Coulomb constant k would change. Like charges would attract, and opposite charges would repel. Since protons are more massive, the universe would acquire a net negative charge. Atoms would consist of protons orbiting a nucleus composed of electrons and neutrons. There would be no difference other than the sign on the charged particles.
How would a proton's motion differ from the motion of an electron placed at the same point in the same gravitational field?
