Roughly 80 percent of the mass of the universe appears to be dark matter: an invisible material that seems to interact with ordinary matter only through gravity, without emitting light or energy. Scientists cannot detect dark matter directly and don't yet know what it's made of, but they track its influence based on the motions of stars and galaxies. The presence of dark matter is necessary to explain the universe's current structure.
