Black holes are already some of the strangest objects in the universe, and scientists sometimes dream up some pretty wild theories about their behaviour. Like maybe they can accumulate dark matter particles and turn into black hole lasers, beaming radiation out into space.

FERNEY-VOLTAIRE, FRANCE -- Some particle physics experiments are easier to ride than others. The giant detectors that take pictures of particle collisions on kilometres-round rings don't really have anywhere to sit, and the intense bureaucracy would probably demand an unwieldy amount of paperwork for would-be riders. The thing that stopped me from riding the whale-sized CAST experiment, however, wasn't fear of disrupting its search for dark matter particles. It was that deputy spokesperson Giovanni Cantatore misplaced the harness.
