Only about 5% of the universe is composed of matter. This includes the visible matter that makes up stars, galaxies, planets, and other celestial objects, as well as the invisible dark matter that exerts gravitational influence on visible matter. The remaining 95% of the universe is composed of dark matter (27%) and dark energy (68%).
The representation of the universe’s composition, including the estimated percentage of matter, dark matter, and dark energy, is based on current scientific understanding.
