The universe is everything that exists, including all matter, energy, and space. It encompasses all physical laws, dimensions, and the history of everything that has ever occurred. The universe is thought to have originated from a single point in an event known as the Big Bang, which occurred approximately 13.8 billion years ago. Since then, the universe has been expanding, with galaxies, stars, and planets forming over time. Our own solar system, including Earth, is a tiny part of the vast universe, and scientists continue to study and explore it in order to better understand its origins and the nature of its components.
