Theoretical physicists have long been trying to devise a complete theory of gravity that would also account for quantum mechanics phenomena, as existing models do not. Such a theory could collectively explain the many intricate ...
A joint research group led by Prof. Sheng Dong and Prof. Lu Zhengtian from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS), investigated the coupling effect between neutron ...

A quartet of space scientists, two from Carnegie Mellon University and two from Harvard University, has found via simulations that it should be possible for interstellar objects to be captured by Earth's gravity. The team, ...
Albert Einstein's general theory of relativity describes how the fabric of space and time, or spacetime, is curved in response to mass. Our sun, for example, warps space around us such that planet Earth rolls around the sun ...
