Difference Between the Universe & the World

The terms universe and world are often used interchangeably, but they refer to two separate things. World typically refers to Earth, encompassing all people, countries, and other life forms. In contrast, the universe includes solar systems, planets, moons, stars, galaxies, and everything contained in intergalactic space, with all matter and energy considered as a whole. Therefore, the world is a part of the universe.
