Answer:

The Universe is all of time and space and its contents. It is made of many millions of millions of stars and planets and enormous clouds of gas separated by a gigantic space. Astronomers can use telescopes to look at very distant galaxies.The universe also includes the physical laws that influence energy and matter, such as conservation laws, classical mechanics, and relativity. The universe is often defined as "the totality of existence", or everything that exists, everything that has existed, and everything that will exist.Our universe began with an explosion of space itself - the Big Bang. Starting from extremely high density and temperature, space expanded, the universe cooled, and the simplest elements formed. Gravity gradually drew matter together to form the first stars and the first galaxies.
