Physics of the cosmos

The physics of the cosmos explores how matter, energy, space, and time interact from the universe’s smallest particles to its largest structures. It explains phenomena like gravity, which pulls objects together; light and radiation, which allow us to observe distant stars; and fundamental forces shaping the cosmos. Through theories like Einstein’s relativity and quantum mechanics, physics reveals the universe’s origins, its expansion, and the formation of galaxies, stars, and planets. Overall, cosmic physics helps us understand both the grand scale of the universe and the fundamental laws governing its behavior.
