The field theoretical formulation of general relativity suggests macroscopic modifications of GR in the form of very specific mass terms. The arising finite-range gravity is a fully consistent theory which approaches GR in the massless limit. All local weak-field predictions of the theory are in perfect agreement with available experimental data. However, some other conclusions of the theory are in a striking contrast with those of GR. They considerably change the properties of gravitational waves, the existence of black hole event horisons and the dynamics of the early and late stages of cosmological evolution. The conclusions of the theory are testable in future experiments and observations. [This contribution is based on: S. Babak and L. P. Grishchuk, Phys. Rev. D61, 024038 (1999), Int. J. Mod. Phys.
