Is dark matter 100% real?
GeneralClass 12AllAnswered 27 Mar 2026
Answer
Dark matter's existence is strongly supported by overwhelming evidence, though it hasn't been directly detected. Evidence includes: galaxy rotation curves (stars orbit too fast for visible matter alone), gravitational lensing (light bending around invisible mass), cosmic microwave background patterns, and large-scale structure formation. About 27% of the universe is dark matter, compared to 5% ordinary matter. While scientists haven't isolated dark matter particles, alternative explanations would reuire even more radical changes to physics.
