Is it within the realm of feasibility that electrons possess an underlying quarklike structure in the manner of protons and neutrons? The hypothesis that electrons can be subdivided into smaller particles termed “electrinos” offers an ideal experimental opportunity to test this concept. Each contingent of such particles could be subjected to repeated expansions into ever […]
