A suitcase-sized quantum sensor could soon reveal hidden water, oil, and even underground mountains—all by tracking how atoms ...

This mission will pave the way for groundbreaking observations of everything from petroleum reserves to global supplies of ...

The Earth’s gravitational field strength (g) is 10 N/kg. This means that for each kg of mass, an object will experience 10 N of force.

Gravitational physicists explore the implications of the general theory of relativity, in which gravitation is a consequence of the curvature of space and time. This curvature thus controls the motion ...

This gravitational strength is particularly impressive because of the stars' small size. When they are formed, neutron stars rotate in space. As they compress and shrink, this spinning speeds up ...
