ABSTRACT:
I will present torsion bigravity, which is a theory of dynamical massive spin-2 field of geometrical origin (dynamical torsion field). I will cover various issues as: - motivation and theoretical basement of this type of modified gravity; - the torsion bigravity world: known solutions and their physical properties, phenomenological consequences. In particular, I will discuss some consequences for the black hole physics.
