Light and Fundamental Forces
Light, a fundamental entity in the universe, plays a pivotal role in our understanding of the fundamental forces governing the cosmos. Among the four fundamental forces—gravity, electromagnetism, weak nuclear force, and strong nuclear force—electromagnetism holds a particularly close relationship with light. Through the electromagnetic spectrum, encompassing radio waves to gamma rays, light manifests in various forms, illuminating the intricate interactions between particles and fields. This interplay between light and fundamental forces underpins the very fabric of existence, shaping the dynamics of matter and energy on both cosmic and subatomic scales.
