Quiz on 🌌 “Dark Matter” — the mysterious, invisible substance that makes up most of the universe's mass
Dark matter is a type of matter that does not emit, absorb, or reflect light, making it invisible to conventional telescopes. Despite being unseen, it exerts a gravitational influence on visible matter, radiation, and the large-scale structure of the universe. Scientists first inferred its existence by observing that galaxies rotate faster than can be explained by the mass of visible matter alone. Dark matter is thought to make up about 27% of the universe's mass-energy content, far exceeding the ordinary matter that forms stars, planets, and humans. Its exact nature remains unknown, but it may consist of exotic particles that interact very weakly with normal matter. Studying dark matter is crucial for understanding galaxy formation, cosmic evolution, and the overall structure of the universe.
