Scientists at the University of Waterloo have captured the first ever composite picture of a dark matter web that connects galaxies together. This composite image confirms that galaxies across the universe are tied together by a cosmic web of dark matter, which until now has been unobservable. "For decades, researchers have been predicting the existence of dark-matter filaments between galaxies that act like a web-like superstructure connecting galaxies together," said Mike Hudson, a professor of astronomy at the University of Waterloo. "This image moves us beyond predictions to something we can see and measure."
