How dark matter is detected?
Correct answer: B. Dark matter is detected through its gravitational effects on visible matter
- A. Dark matter is detected through its absorption effects
- B. Dark matter is detected through its gravitational effects on visible matter
- C. Dark matter is detected through its absorption and gravitational effects
- D. Dark matter cannot be detected
Explanation
Dark matter emits and absorbs little or no detectable light, so it is inferred from gravity, such as its effects on galaxy rotation and gravitational lensing. Its gravitational influence on visible matter is therefore the key evidence.

About Astronomy and Space
Astronomy covers the structure and motions of the solar system, planets, satellites, comets, asteroids and meteoroids, together with gravity, eclipses, seasons and phases of the Moon. It also introduces stars, galaxies, nebulae, black holes, space telescopes and satellites, while distinguishing rotation from revolution and meteors from meteorites.
