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.

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 ...

If the two rates become increasingly different, it will mean, says Dr. Dicke, that the strength of gravitation is changing. Dr. Dicke does not propose to use any ordinary gravitational clock ...

According to Einstein’s theory of general relativity, gravitational waves warp spacetime. In the process, they could imprint permanent changes, or “gravitational memory,” on their surroundings.
