what is the universe
Answers
The universe is the name that we use to describe the collection of all the things that exist in space. It is made of many millions of millions of stars and planets and enormous clouds of gas separated by a gigantic empty space.
Astronomers can use telescopes to look at very distant galaxies. This is how they see what the universe looked like a long time ago. This is because the light from distant parts of the universe takes a very long time to reach us. From these observations, it seems the physical laws and constants of the universe have not changed.
Physicists are currently unsure if anything existed before the Big Bang. They are also unsure whether the size of the universe is infinite.
