Hey everyone! Dark matter, which makes up the majority of the universe’s mass, remains one of the biggest mysteries in cosmology. Although we cannot detect it directly, its gravitational effects shape galaxies and cosmic structures.
A recent study published in Physical Review Letters explores new ways to detect low-mass dark matter candidatesusing ultra-sensitive detectors. While no definitive detection has been made yet, the study sets important constraints on possible mass ranges for dark matter particles. These constraints help refine theoretical models and bring us closer to understanding the true nature of dark matter.
This research is a significant step in narrowing the search. If future experiments confirm these findings, we could be on the verge of one of the biggest breakthroughs in modern physics!

What kind of detectors are used in these experiments?
They use ultra-sensitive cryogenic and quantum detectors, capable of detecting minuscule interactions that could hint at dark matter particles.
