General review of various modified gravity is done. special attention is paid to F(R) and F(G) modified gravity. The realistic exponential model which unifies inflation with dark energy is discussed and compared with LCDM theory. It is shown how modified Gauss-Bonnet gravity may give realistic inflation while it is still compatible with recent GW event data. Stellar astrophysics in the...
We discuss a model of the universe where dark energy is replaced by
electrically-charged extremely-massive dark matter. The cosmological
constant has a value of the same order as the mean matter density,
consistent with observations, and is obtained classically without fine-tuning.
Wormholes have never been observed but proven to be valid solution to
field equations of general relativity. Patton and Wheeler postulated that
the vacuum state of the gravitational field features a Planch-scale state
virtual geometries known as quantum foam. In early universe, some of
these geometries include submicroscopic wormholes, and their existence
is governed by the uncertainty...
I review the status of the standard model of cosmology in light of recent observations discussing the current tensions and some different
