Select the correct answer from the list dark matter blank absorbs light blank emits radiation and blank then observed directly

Answer 1

Dark matter does not absorb light, does not emit radiation, and therefore cannot be observed directly. Instead, it is inferred from its gravitational effects on visible matter and the large-scale structure of the universe. So the statements would be:

1. Dark matter does not absorb light.
2. Dark matter does not emit radiation.
3. Dark matter is not observed directly.

If you need to fill in the blanks specifically with "does not," then the correct completion of the sentence would be:

"Dark matter does not absorb light, does not emit radiation, and is not observed directly."
