The Universe is all of space and time and their contents, including planets, stars, galaxies, and all other forms of matter and energy. The exact size of the universe is unknown. Scientists believe the universe is still expanding outward. The expansion of the universe is the increase of the distance between two distant parts of the universe with time. Science says the universe could be a hologram, a computer program, a black hole or a bubble.
