SCMP China reports: A detector that will form part of a 3 million km-long triangular ruler has passed ground tests 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 called Taiji that is designed to pick up gravitational waves rippling through the fabric of space and time.

“The ground tests [of the optical core] were a success, and all the key numbers met the strict demands of the mission. That means that the core measurement system of Taiji has officially moved from [theory] to real hardware,” the report said.
