f (R)-Gravity Matched With Large Scale Structure and Cosmological Observations

摘要: The so called f (R)-gravity could be, in principle, able to explain the accelerated expansion of Universe without adding unknown forms dark energy/ matter but, more simply, extending General Relativity by generic functions Ricci scalar. However, a part several phenomenological models, there is no final (R)-theory capable fitting all observations and addressing issues related presence energy matter. Astrophysical are pointing out huge amounts ”dark matter” energy” needed observed large scale structures cosmic accelerating expansion. Up now, experimental evidence has been found, at fundamental level, such mysterious components. problem be completely reversed considering as ”shortcomings” Relativity.
