7 Summary
67
divergences as nonphysical ones [133], bimetric gravity based on use of the additional
second-rank symmetric tensor, Palatini approach treating metric and connection as
independent variables, and, clearly, modifications of gravity based on use of nonRiemannian geometry, especially, torsion and nonmetricity. To finish, we note again
that in gravity there is still much more questions than answers.
