China's first satellite to conduct experiments on key technologies related to space-based gravitational wave detection, Taiji-1, has successfully completed its in-orbit tests, the Chinese Academy of Sciences (CAS) announced Wednesday. The satellite, sent into orbit on Aug. 31, 2019, is China's first such kind of satellite, and has completed its in-orbit experiments, making a breakthrough in the country's gravitational wave detection, said Wu Yueliang, chief scientist of the project. After four months of tests and experiments, it was proved that the satellite system has performed well in orbit and completed all the experiments required for research, Wu added. With the success of Taiji-1's in-orbit tests, the first goal of CAS's three-step strategy to implement the program has been successfully achieved. Taiji-1 will conduct more expansion experiments in the next stage, said Wu. Source: Xinhua News Agency
Scientists closer to solving Newton's 'three-body problem' Washington (UPI) Dec 18, 2019 For more than three centuries, Newton's laws of motion have helped scientists understand the relationships between body of mass and the forces that act on it, like the forces acting on a planet orbiting the sun. Newton's equations weren't perfect, however. When trying to account for three bodies - a moon orbiting a planet orbiting a sun, for example - Newton struggled to solve the equations related to mass and motion. Simply put, neither Newton's laws of motion, nor any physical ... read more
