The axion may help clean up the messy business of dark matter
Briefly

The article discusses the axion, a hypothetical particle suggested to address dark matter's complexities. Although evidence of axions remains elusive, they are viewed as potentially transformative for cosmology. Dark matter's existence is widely accepted based on disparities between visible matter and inferred mass, leading astrophysicists to consider non-visible particles. Investigation into axions is vital for resolving longstanding issues associated with dark matter and for showcasing novel methods of discovery in the field of high-energy physics.
The search for axions remains crucial in the ongoing quest to understand dark matter, though no direct evidence for these particles has yet been found.
Dark matter is accepted by scientists due to inconsistencies in mass measurements of visible and non-visible matter throughout the universe.
