Approximately 85% of the mass of the universe is thought to be composed of dark matter, a mysterious substance that does not emit, absorb, or reflect light, making it completely invisible and detectable only through its gravitational effects. While normal matter, which makes up stars, planets, and all visible structures, comprises just about 15% of the universe, dark matter plays a crucial role in shaping the cosmos. Its presence helps explain the rotation curves of galaxies, gravitational lensing phenomena, and the large-scale structure of the universe. Despite extensive efforts to understand its nature, dark matter remains one of the most significant unsolved mysteries in modern astrophysics, prompting scientists to explore various theories and search for potential particles that could comprise this elusive substance.
