Dark matter is a hypothetical form of matter that is believed to make up a significant portion of the total mass in the universe. It does not interact with electromagnetic radiation, which is why it does not absorb or emit light. This makes it invisible and difficult to detect using traditional telescopes or other astronomical instruments.
Despite its lack of direct observation, scientists infer the existence of dark matter based on its gravitational effects on visible matter and the structure of the universe. Observations of galaxies, galaxy clusters, and the cosmic microwave background radiation provide strong evidence for the existence of dark matter.
Different experiments, such as the detection of weak gravitational lensing, the observation of galaxy rotation curves, and measurements from particle accelerators, also support the presence of dark matter. However, its precise nature and composition remain unknown, making it one of the biggest mysteries in modern physics and cosmology.

would that be goocd
Yes, the absence of direct observation and the lack of interaction with light and radiation make it challenging to study dark matter. However, the existence of dark matter is crucial for explaining various astronomical observations and the formation of structures in the universe. By studying its gravitational effects and the way it interacts with visible matter, scientists can infer its presence and deduce its properties indirectly. The continued study of dark matter is essential for advancing our understanding of the universe and its fundamental constituents.

The characteristic shared by both dark matter and baryonic matter is that they both have gravity.
so itsn AAAA
I apologize for the confusion. The correct characteristic shared by both dark matter and baryonic matter is that they both have gravity.
so a b c or d
The correct choice is A) They both have gravity. Both dark matter and baryonic matter interact through gravity.
