The answer is the universe. It can be defined as everything that exists, everything that has occurred, and everything that will exist. It is also all of space and time and its contents which comprises of moons, planets, minor planets, stars, galaxies, the contents of intergalactic space and all matter and forms of energy (including electromagnetic radiation and matter), and the physical laws that relate them. The Universe covers all of life, all of history, and some theorists and scientists recommend that it even encompasses notions such as logic and mathematics.
