Earth and the Moon are forever locked in a gravitational embrace that has played a critical role in determining the fate of both worlds. Although they have grown more distant since their formative ...

China has taken a monumental leap in scientific research by activating the world's most advanced hypergravity machine. the Centrifugal Hypergravity and Interdisciplinary Experiment Facility (CHIEF).

Researchers have discovered there was an anomaly in Earth's gravitational field between 2006 and 2008, potentially caused by ...

Every time an astronaut returns from space, they experience a force four times their body weight. As they leave the microgravity of space and re-enter Earth’s atmosphere, their bodies witness ...

In 2007, something strange happened over the eastern Atlantic Ocean. According to satellites orbiting Earth, our planet's gravity field developed a continent-scale anomaly before subsiding to its ...

The Indian Ocean "gravity hole" is a region where Earth's mass is reduced, leading to weak gravitational pull, lower-than-average sea levels and a puzzle scientists have only just begun to solve. When ...

Wide binary stars with separation greater than about 2000 astronomical units are interesting natural laboratories that allow a direct probe of gravity at low acceleration weaker than about 1 nanometer ...
