Understanding Dark Matter and Axions
Dark matter is an elusive and mysterious component of the universe, making up about 85% of its total mass. It does not emit, absorb, or reflect light, making it undetectable by traditional observation methods. The existence of dark matter is inferred from its gravitational effects on visible matter, cosmic microwave background radiation, and the large-scale structure of the universe. Axions, hypothetical particles proposed in 1977, are considered a leading candidate for dark matter due to their predicted properties. If axions exist, they may help explain both the composition of dark matter and the behavior of galaxies.
The intersection of particle physics and cosmology has made axions a focal point for researchers aiming to unlock the secrets of dark matter. Their theoretical underpinnings suggest that axions could fulfill the criteria for dark matter candidates, such as being weakly interacting and of very light mass. With advancements in quantum technologies and techniques like laser optics, scientists are getting closer to detecting these elusive particles, which could provide groundbreaking insights into the nature of the universe.
