Dark matter

A slowly evolving system aligned along a filament in the voids of the cosmic web could represent early galaxy formation

Dark matter is an invisible form of matter that has mass. It does not emit or absorb heat, light, or any other electromagnetic waves. Also, it “weakly” interacts with ordinary matter, making it even more stealthy. Of all the branches of science, one of the most popular is astronomy, and for good reason. Who on Earth has ever wondered about twinkling stars, the shining Moon, and the occasional meteors that light up our night sky! Since the invention of the telescope, our curiosity about the…

The mysterious stuff thought to bind galaxies together may be more complex than we thought – and now we are starting to tease apart the possibilities, says Stuart Clark

If you want to find something that's invisible except for its gravitational effects, look down the steepest gravity wells in the universe.
