Today we are in a position to roughly assess the vastness of our universe. Our vast Earth is a simple shaped planet in the Solar System, orbiting around a star called the Sun. Despite being the lord of the solar system, the Sun is also a simple and average size and age star of the galaxy called Milky Way.
There are millions of other galaxies in this vast universe like our galaxy. Therefore, our universe is a huge cluster of galaxies. Today's scientists even believe that the universe is not one but many. Their reasoning behind this is that there is no end to the space, so there is a possibility of more than one universe.
