Detailed explanation-1: -The universe is everything. It includes all of space, and all the matter and energy that space contains. It even includes time itself and, of course, it includes you. Earth and the Moon are part of the universe, as are the other planets and their many dozens of moons.
Detailed explanation-2: -by Ron Kurtus (updated 8 February 2022) Matter is defined as anything that takes up space and has mass. Everything around you is made up of matter. Matter is a generic term for the “stuff” around you. Taking up space means that an object has a measurable size or volume.
Detailed explanation-3: -There are basically three possible shapes to the Universe; a flat Universe (Euclidean or zero curvature), a spherical or closed Universe (positive curvature) or a hyperbolic or open Universe (negative curvature).
