This focus point issue of European Physical Journal Plus (EPJ Plus) aims to reflect the diversity of modified gravity theories and of their applications to the cosmological problem. The scope of the covered topics is enough broad, ranging from teleparallel gravity and gravitino problem in extended gravity up to traversable wormholes in f(R) gravity, from a model of lattice universe, up to addressing the Hubble tension within modified gravity. There are also papers dealing with modified gravity tests, namely, with Lense–Thirring precession, with observational constraints, including the black hole shadow, with the Solar system constraints to Brans–Dicke and Palatini f(R) theories, as well as with suggestions for high-precision gravitational redshift measurements as probes for gravity theories.
This collection also indicates that the modified gravity and cosmology are widely developing areas being in permanent contact with ongoing observational surveys and experimental programs.
