QR4.4 Quarks – Thinkers Corner

Ordinary matter is made of atoms whose mass comes almost entirely from nuclei, so quarks not electrons represent the solidity of matter. Quark charges also come in unexpected thirds for no known reason, that conveniently add or cancel when they combine into positive protons or neutral neutrons. One proton and one electron then formed the first atom, of Hydrogen, and other atoms arose when neutrons joined protons in their nuclei, again for an unknown reason. Quarks are then the main constituent of matter, so does a processing model also explain them? If not, it fails as a model of matter.
