The universe is everything we can touch, feel, sense, measure, or detect. It includes all of space and time, and everything that exists within it — stars, planets, galaxies, black holes, dark matter, and even the smallest particles.
Our universe began about 13.8 billion years ago with a massive explosion known as the Big Bang. Since then, it has been expanding continuously. Galaxies are moving away from each other, and space itself is stretching.
One of the most fascinating aspects of the universe is its vastness. It contains billions of galaxies, each with billions of stars. Our home, the Milky Way, is just one of them. Earth orbits a medium-sized star we call the Sun, which is just one of many in our galaxy.
Scientists are still exploring the mysteries of the universe. What is dark energy? Are there other forms of life out there? Will the universe keep expanding forever? These questions continue to drive research and inspire curiosity.
In the end, the universe is not just a place — it’s the greatest mystery we are all a part of.
