The universe
The universe consists of all space and the matter that space contains, including galaxies, stars, planets, and other celestial bodies. It also includes dark matter and dark energy, which are thought to make up a significant portion of the universe.
All matter and energy in space, including stars, planets, galaxies, and dark matter, make up what is known as the universe. This vast expanse of space contains everything that exists and interacts according to the laws of physics.
Everything in space is part of the universe, which includes all matter, energy, and other physical entities. The universe encompasses galaxies, stars, planets, asteroids, comets, dark matter, and more.
Space is primarily composed of three key components: matter, energy, and the fabric of spacetime. Matter includes all physical substances, from stars and planets to cosmic dust. Energy encompasses various forms, such as electromagnetic radiation and kinetic energy, which influence the movement and interactions of matter. Spacetime, a concept from Einstein’s theory of relativity, combines the three dimensions of space with the dimension of time, providing a framework for understanding the universe's structure and behavior.
Space, as in the vast expanse that includes galaxies, stars, planets, and other celestial objects, is referred to as the universe. The universe encompasses all of space, time, matter, and energy. It is the totality of everything that exists, including both observable and unobservable components.

the universe
The universe is defined as everything - all space, all time, all matter and energy.
A universe is a vast region that holds all known matter and energy, including galaxies, stars, planets, and other celestial bodies. It encompasses everything that exists, from the smallest particles to the largest structures.
Space is the three-dimensional fabric containing all matter, energy, and forces.
