Current estimates suggest that about 27% of the universe is dark matter, compared to only about 5% for ordinary matter. Despite decades of research, the nature of dark matter remains one of the greatest mysteries in physics. Is it composed of undiscovered particles? Could it be related to exotic phenomena such as primordial black holes?

Scientists are exploring multiple avenues to uncover the secrets of dark matter. Particle accelerators like the Large Hadron Collider attempt to produce dark matter particles in high-energy collisions. Deep underground laboratories look for rare interactions between dark matter and atomic nuclei. Astronomers map the gravitational lensing of galaxies to detect its distribution across the universe.
