This sort of study attempts to detect actual dark matter particles as they pass by. Such experiments are increasingly sensitive, and seem to be showing “hints” of dark matter. The astrophysical evidence for dark matter is more extensive and diverse, but tells less about what dark matter actually is.
A third experiment has detected tantalising signs of dark matter. The finding raises more questions than answers, however, as two other experiments have found no sign of the mysterious stuff, which is thought to create the gravity that holds spinning galaxies together, accounting for about 85 per cent of all matter in the universe.
