The Universe

The universe is the vast cosmos that includes everything we know: galaxies, stars, planets, and all forms of matter and energy. It began around 13.8 billion years ago with the Big Bang, an enormous explosion that spread out space and time. The universe is constantly expanding, and it's governed by fundamental forces like gravity. It contains billions of galaxies, each with millions or billions of stars. While we're still uncovering its mysteries, the universe offers insights into the origins of existence, the nature of time, and potentially the existence of other life forms beyond our planet.
