A characteristic of dark matter is that it does not interact with baryonic matter (Option: O it does not interact with baryonic matter).

The characteristic of dark matter is that it does not interact with baryonic matter, which refers to the ordinary matter that makes up atoms and everything we can see. Dark matter does not interact with electromagnetic radiation, which means it does not emit, absorb, or reflect light. This is why we cannot directly observe dark matter using telescopes or other instruments that detect electromagnetic radiation. The presence of dark matter can, however, be inferred indirectly through its gravitational effects on visible matter and through its impact on the large-scale structure of the universe.
