THE TWIN-EFFECT AND THE RED-SHIFT.
Abstract
The asymptotic relationship between twin-effect and acceleration red-shift is discussed from a point of view of theory and experiment. The paradoxical aspects of the twin effect can be reduced to two major factors: (1) the detour paradox, which means that the world-line geodesic within the light cone gives a maximum path - hence detouring saves proper-time; (2) the assumption that proper-time is a characteristic measure for biological aging. A number of physical aging phenomena are then reviewed. Accepting the physical reality of the twin-effect of proper-time, one can then delineate two contributions to this effect: (1) the kinematical effect associated with uniform translational motion, and (2) the acceleration effect related to the red-shift. The measurement of the acceleration red-shift by Hay et al (1960) may be considered as an unambiguous confirmation of the twin-effect in which primarily the red-shift contributes. No comparable check on the kinematical component is as yet available. In fact, experimentally it is not feasible to isolate the latter contribution. (Author)
