Witness gravity’s quantum side in the lab: Physicists should rethink interference experiments to reveal whether or not general relativity follows classical theory, argue Chiara Marletto and Vlatko Vedral. (Nature, 11 July 2017)
A planetary system is a set of gravitationally bound non-stellar objects in orbit around a star or star system.
All planets on the planetary system revolving around the Sun due the force of gravity between the Sun and planets. They didn’t to get collide or fall toward the Sun due to the fact, there is no motion without a cause. There are also forces from planets and medium between them in the opposite direction. This phenomena can be pictured in the formula:
Energy in =Energy out, and the result is a balance.
