Now, Chinese scientists have made a step forward in turning that idea into hardware – only in reverse. Science and Technology Daily reported on Saturday that a team from the Institute of Mechanics at the Chinese Academy of Sciences had developed the optical core of a giant space detector to listen to the universe. The detector is part of a space-based gravitational wave project...
