The “gravity hole” formed at least 70 million years ago after convection in Earth’s mantle. The weak gravity could impact our ...
Gravity feels reliable—stable and consistent enough to count on. But reality is far stranger than our intuition. In truth, the strength of gravity varies over Earth's surface. And it is weakest ...
In A Nutshell Antarctica, not the Indian Ocean, hosts Earth’s strongest nonhydrostatic geoid depression when scientists ...
A shifting of Earth’s poles, referred to as ‘True Polar Wander,” combined with the sinking of tectonic plates during the Cenozoic Era, altered the planet’s interior, with rising hot mantle material ...
The Earth is a dynamic system—it has a fluid, mobile atmosphere and oceans, a continually changing distribution of ice, snow, and groundwater, a fluid core undergoing hydromagnetic motion, a mantle ...
A conspiracy theory that spread on social media claims that gravity will disappear for seven seconds this August, and that NASA is aware that this will happen. A physics professor explains why this is ...
Buckle up, nerds: NASA is building the first quantum gravity sensor for space—a suitcase-sized instrument that could soon be measuring everything from subterranean water to hidden reserves of ...
Gravitational anomalies detected by NASA and the German Aerospace Center’s GRACE satellites confused scientists for years. Here’s what happened.
The Earth is a dynamic system constantly undergoing change. As the processes of change affect the Earth's topography—the heights of land, ice, and ocean surfaces—they also modify the distribution of ...
