In the vastness of space, the universe is everything that exists. It encompasses all of time and space, including all matter and energy. The universe is believed to have begun with the Big Bang, a massive explosion that created everything we see today.
The universe is constantly expanding and evolving. Over time, it has become more complex, with galaxies forming and stars shining. Our own solar system is just a small part of this ever-changing universe.
There is still much to learn about the universe. Scientists are constantly making new discoveries about its size, structure, and history. With new technology, we may one day be able to understand even more about this infinite expanse.
