SDU researchers present a new model for what dark matter might be
Odense, Denmark (SPX) Mar 17, 2016
Dark matter is all around us. Though no one has ever seen it, and no one knows what it really is, indisputable physical calculations state that approximately 27% of the universe is dark matter. Only five % is the matter of which all known materials consist; from the smallest ant to the largest galaxy. For decades, researchers have tried to detect this invisible dark matter. Several types of devices have been put up on Earth and in space to capture the particles that dark matter is supposed to cons ... read more
