Dark Matter Mystery

Scientists at the Large Hadron Collider (LHC) are continuing their search for dark matter, the elusive substance that makes up about 85% of the universe's mass. While no direct detection of dark matter particles has been made yet, experiments at the LHC and other facilities are narrowing down the possibilities and exploring new theories about the nature of dark matter. Solving the mystery of dark matter is one of the biggest challenges in modern astrophysics.
