Why are quarks the only entity that carries a fractional charge? For example observations tell us that the Up, Charm and Top have a fractional charge of 2/3 while the Down, Strange and Bottom have a fractional charge of -1/3. However we also know that we live in a universe made up of three dimensions. Is it possible that the 1/3 fractional charge of quarks is related to the fact that our environment and theirs is made up a of three-dimensions as is suggested in our article "The Geometry of Quarks" >
