The word universe is complicated to define, but is currently defined as everything we can touch, feel, perceive, measure or detect (the solar system, the earth, the moon, etc). It encompasses living things, planets, stars, galaxies, clouds of dust, light and even time. That's why before the Universe was born, there was no time, space or matter.
The universe contains billions of galaxies, each with millions or billions of stars. The space between stars and galaxies is largely empty.
The universe is incredibly big, and nobody knows its exact size, because we are unable to see the edge. It has not always been the same size throughout its history. Scientists believe that it started with a Big Bang and since then it has been expanding at great speed. Therefore, the area of ​​space that we now see is billions of times larger than when it was very young.
