universe

Any complete system

The universe is everything that exists—all matter, energy, space, and time considered as a whole.

In astronomy and physics, the universe refers specifically to the cosmos: galaxies, stars, and the vast emptiness between them.

More loosely, universe can mean a particular sphere of experience or knowledge: the universe of jazz, the fashion universe.

In fiction, a universe is a self-contained world with its own rules: the Marvel universe.
