Scientists Make Groundbreaking Discovery in Search for Dark Matter In a major breakthrough, researchers claim to have detected a potential signal of dark matter, a mysterious and elusive substance believed to make up approximately 27% of the universe. According to a new study, scientists have observed a faint glow emanating from the center of the Milky Way, which could be a sign of dark matter particles interacting with normal matter. The discovery, if confirmed, could revolutionize our understanding of the cosmos and shed light on the long-standing mystery of dark matter's existence.
