On the measurement of proper time in general relativity by means of atomic clocks
- 13 Downloads
The quantity τ, which is called the proper time of a particle in the general theory of relativity, has the following meaning: it is the time measured by clocks moving with the particle. The question arises of how proper time is measured by real clocks. At present, atomic clocks are the most accurate, being stabilized by the frequency of intraatomic transitions. In the present paper, the stability of the reference frequency of such clocks is considered, i.e., the possible discrepancies between the proper time and the time measured by atomic clocks.
