Predictions of the general theory of relativity are free from ambiguity

The set of the complete Schwarzschild solutions for a static spherically symmetric homogeneous ideal liquid of finite volume is examined. Using the example of the phenomenon of the red shift of frequency in a gravitational field it is shown that the use of different types of solutions leads, contrary to the assertion of authors of a relativistic theory of gravitation, to unambiguous predictions of gravitational effects by the general theory of relativity.
