The nature of dark matter is still not fully understood, and there are various theories and hypotheses regarding its origin. While it is challenging to pinpoint the exact properties and behavior of dark matter, the prevailing view among scientists is that dark matter is not an emergent property of normal matter interacting over long distances.
Observational evidence suggests that dark matter is non-baryonic, meaning it is not composed of the same types of particles that make up ordinary matter. It does not interact electromagnetically and does not emit or absorb light, which is why it is termed "dark." Dark matter's presence is inferred through its gravitational effects on visible matter and its impact on the large-scale structure of the universe.
There have been proposals and alternative theories suggesting modifications to the laws of gravity, such as Modified Newtonian Dynamics (MOND), which aim to explain the observed gravitational effects without the need for dark matter. However, such theories face challenges in explaining a wide range of observations, including the behavior of galaxies and the clustering of matter on large scales.
The prevailing understanding is that dark matter is likely to be composed of new, yet-undiscovered particles that do not interact strongly with electromagnetic radiation but interact gravitationally. These particles would be different from the known particles of the standard model of particle physics, which describe the constituents of ordinary matter.
To summarize, while the exact nature of dark matter is still a subject of active research, the prevailing scientific consensus suggests that it is not an emergent property of normal matter interacting over long distances. Rather, it is believed to be made up of non-baryonic particles that interact gravitationally but exhibit little to no interaction with electromagnetic radiation.
