A supergroup is a group of particles that have the same mass, coefficient of friction and charge, but may have different magnetic fields, temperatures and electrical charges. They are also all part of the same universe and may interact with each other. Supergroups are usually very big, and can act like one big particle. For example, atoms form a supergroup and act like one big particle in their interactions with other particles. Supergroups are important in physics because they help us better understand how the universe works.
