Researchers the world over have long believed that 70 percent of the universe is composed of dark energy, a substance that makes it possible for the universe to expand at an ever-increasing rate. But in a new study, researchers tested a model which suggests that the universe's expansion is due to a dark substance with a kind of magnetic force.

A new black hole breaks the record - not for being the smallest or the biggest - but for being right in the middle. The recently discovered 'Goldilocks' black hole is part of a missing link between two populations of black holes: small black holes made from stars and supermassive giants in the nucleus of most galaxies.
