However there is not exact explanation of what dark matter really is, so there are still Noble Prices for those who can come up with a reasonable explanation.

Answer 2

Dark matter does not interact with light, making it invisible to traditional observation methods like telescopes. Its presence is inferred from its gravitational effects on visible matter and light. Efforts to directly detect dark matter particles are ongoing but challenging due to their hypothesized weak interactions with normal matter.
