Researchers at the University of Waterloo have created the first map showing how our universe's elusive dark matter interacts with galaxies. Dark matter makes up about 25 per cent of our universe. Because of its extreme gravity, dark matter bends light, in keeping with Einstein's theory of general relativity. It's been theorized that galaxies are connected through dark matter in a type of cosmic web. Using the Canada-France-Hawaii Telescope, the researchers were able to detect the dark matter through weak gravitational lensing.
