Question

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."
