Several theories attempt to explain the nature of dark matter:
Weakly Interacting Massive Particles (WIMPs): These hypothetical particles interact via the weak nuclear force and gravity, making them difficult to detect. Axions: These are extremely light particles proposed as a solution to the strong CP problem in quantum chromodynamics and are also potential dark matter candidates. Modified Newtonian Dynamics (MOND): This alternative theory suggests modifying the laws of gravity rather than invoking dark matter to explain astronomical observations.
