No, it is not possible to predict time dilation solely based on angular measure. Time dilation is a relativistic effect that depends on several factors, including relative velocity and gravitational fields.
Angular measure, or the measurement of angles, is not sufficient to determine time dilation because it does not provide information about the relative motion or gravitational influences between the objects involved. Time dilation is a consequence of the combined effects of relative velocity and gravity, as described by Einstein's theory of relativity.
To accurately predict time dilation, one needs to consider the relative velocity between the observer and the moving object, as well as the gravitational field strength in the vicinity of the objects. These factors influence the curvature of spacetime and, in turn, affect the passage of time.
Therefore, a comprehensive understanding of time dilation requires taking into account more than just angular measure; it necessitates considering the relative motion, speeds, and gravitational fields involved in the scenario.
