Some areas rise where gravity is stronger, while others dip where it is weaker. These variations, called "geoid anomalies," reveal how mass is distributed deep within the Earth. One of the most ...

When teachers explain ocean tides, they frequently describe how the moon's gravity pulls on Earth and all of its water. This, they often say, leads to a gravitational imbalance, which stretches ...

believes his team has built a gravity-defying propulsion system that does exactly that. Buhler, who helped found the Electrostatics and Surface Physics Lab at NASA’s Kennedy Space Center ...

NASA and partners are building the first quantum gravity sensor for space, a breakthrough instrument that uses ultra-cold ...
