Universum
The universe is all of space, time, matter, and energy that exists. It includes planets, stars, galaxies, and even the emptiness between them. The universe began about 13.8 billion years ago with the Big Bang, a massive expansion from a hot, dense point. It is constantly expanding and evolving, governed by physical laws like gravity and light. Studying the universe helps us understand our origins, the nature of matter, and the fundamental forces shaping everything around us. In essence, it is the vast, complex, and dynamic backdrop of everything we see and experience.
