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 ...

satellite configurations are far more sensitive to changes in Earth's gravity field than sensors on the surface. They stay within a detectable proximity to each other in a precise formation; the ...

You may have seen videos of astronauts jumping on the moon. Their movements appear bouncier and lighter than how we move on Earth, and this is thanks to gravity. Gravity is "the force by which a ...

New findings suggest that ordinary sound has negative gravitational mass. This is an Inside Science story. (Inside Science) -- The sound of a sonic boom may produce about the same magnitude of ...

The answer depends on your location, your distance from the centre of Earth and any local variation in gravitational field strength due to the density of underlying rock. Crunching the numbers, the ...
