The down quark has a charge of -1/3. The electron has a charge of -1. Each down quark has 1 charge object. Each electron has 3 charge objects. The electron is small. Because the electron is small, the three charge objects in the electron cannot repel each other. The three like charge objects in an electron attract each other. The three like charge objects in one electron repel the three like charge objects in another electron. Like charge can both attract and repel. Whether a charge object attracts or repels another charge object depends on its relationship with the other charge object. All charge objects in the universe are relationally locked. The mass/gravity object is an object of the same basic type as the charge object. The mass/gravity object has its observed characteristics because of where it is in the relationship. All the mass/gravity objects in the universe are relationally locked with each other. All the mass/gravity objects in the universe have the same relationship with each other as the three charge objects in an electron have with each other.
