Two kilometres underground near Sudbury, Ont., a machine has reached a temperature so low it barely seems real. Inside SNOLAB, scientists have cooled the Super Cryogenic Dark Matter Search, or ...

Scientists used gravitational waves from black hole mergers to search for dark matter and found a surprising clue.

Dark matter is thought to make up most of the matter in the universe, but the only way it interacts with its surroundings is through gravity. If two colliding black holes spiral through a dense region ...

Dark matter is some kind of substance that has gravity—it holds galaxies together—yet cannot be directly seen with any instrument yet created. We know it’s out there because of the effects it has on ...

Deep in an active nickel mine near Sudbury, Ontario, researchers are installing and calibrating a set of sensitive detectors. They hope that the location roughly 6,800 feet underground will screen out ...

Modern cosmology assumes dark matter exists. But what makes us so certain that dark matter is the answer—and what if we're wrong? Reading time 8 minutes A huge chunk of the universe is missing. It’s ...
