SummaryOn the basis of the height difference between the CNR cosmic-ray laboratory at Plateau Rosa, 3500 m, and Turin, 250 m above s.l., a direct measurement of the terrestrial gravitational shift has been made by the comparison of the time scales of two cesium beam atomic frequency standards of the Istituto Elettrotecnico Nazionale «Galileo Ferraris». The principle of equivalence predicts the effect Δt/t=−ΔU/c2=3.54·10−13, corresponding to the gain of the standard at mountain altitudes Δt/t=30… Expand
Relativistic effects on time scales and signal transmission
The current view of space-time chronometry is reviewed in its different elements, clock transport and the ‘twin paradox,’ the effect of a gravitational field, and the Doppler effect. In this view aExpand

The theory of general relativity was born more than one hundred years ago, and since the beginning has striking prediction success. The gravitational redshift effect discovered by Einstein must beExpand
Chronometric measurement of orthometric height differences by means of atomic clocks
We report on the experimental results of testing a new physical method of determination of the gravitational potential differences and orthometric heights by measuring the relativistic effect ofExpand

Theories of gravity and experimental tests in the post-newtonian limit
The postulates upon which is founded general relativity (in particular the principle of equivalence) are in fact the underlying foundations of a large class of competing theories, the so-calledExpand

This paper puts forward a broad critical analysis of the concept of physical time. Clock effect is conceived as a consequence of the variation of the gravitational or pseudo gravitational potential,Expand

The equivalence principle and the notion of an ideal clock running independently of acceleration suggest that clocks are unaffected by gravity. The apparent contradiction with the gravitationalExpand
