Answer 4

The characteristic of dark matter is that it does not interact with baryonic matter.

Answer 5

The correct characteristic of dark matter is that it does not interact with baryonic matter. To determine this, scientists have relied on indirect observations and measurements of its effects on visible matter. Dark matter does not emit, absorb, or reflect electromagnetic radiation, making it invisible and undetectable by traditional means. Its existence has been inferred through its gravitational effects on visible matter and the large-scale structure of the universe. Therefore, humans cannot see dark matter directly, and it remains a mysterious and intriguing component of the universe.
