I believe the end of my physics textbook in college just said “be grateful that the charge on the electron is what it is because without it our universe wouldn’t exist if it was even slightly different” or something to that effect. Our universe may be the trillionth trillionth one created and we are in an anthropomorphic universe just like we are on an anthropomorphic planet. It always makes me grateful. >The charge on a proton is +1.602 x 10-19 C, and the charge on an electron is -1.602 x 10-19 C.
