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 ...
There’s a new entrant in the competition to develop ever-tinier instruments that can detect changes in our planet’s gravitational field — a tabletop device roughly the size of two smartphone stacked ...
