How do we measure gravity? Gravity is measured in what is called a Gravimetry and this measures the strength of a gravitational field. The instrument used to measure this is called a gravimeter, and to put it simply it measures the constant acceleration of gravity in a downward direction. Exp...
We point out here that three possible roads to approach thenature of gravity can be taken in future. The first one is the comingobservations of gravitational waves from both ground-borne and space-bornegravitational-wave detectors. A system involving either black holeor neutron star has certainly...
