fundamentally different interactions

Fundamental interactions are the basic forces that govern how particles and objects behave in the universe. There are four main types: gravity, which attracts objects with mass; electromagnetic, which acts between charged particles and enables electricity and magnetism; strong nuclear, which holds the nucleus of an atom together; and weak nuclear, which is involved in certain radioactive decays. Each interaction operates differently, with gravity affecting large scales like planets and galaxies, while the others influence atoms and subatomic particles. Together, these forces shape the structure and behavior of everything around us.
