Why is 95% of the universe invisible?
GeneralClass 12AllAnswered 27 Mar 2026
Answer
Approximately 95% of the universe consists of dark matter (27%) and dark energy (68%), neither of which emits, absorbs, or reflects light, making them invisible. Only 5% is ordinary matter (atoms, stars, planets, us). Dark matter reveals itself only through gravitational effects, while dark energy drives the universe's accelerating expansion. These invisible components are inferred from their effects on visible matter and space itself galaxy rotation, gravitational lensing, and cosmic expansion rates.
