Do Scalar Tensor Cosmologies naturally explain all the current cosmological observations ?

TL;DR

Scalar tensor cosmologies can potentially account for all current cosmological observations through their internal dynamics, predicting a universe moving towards matter dominance and a slowdown in acceleration.

Contribution

This paper demonstrates that scalar tensor theories can explain cosmological data without dark energy, highlighting their natural explanatory power.

Findings

Universe tends towards matter dominance

Dark energy component diminishes over time

Cosmic acceleration is slowing down

Abstract

It is shown that the general scalar tensor cosmologies may explain all the current cosmological observations without the need of invoking any ad hoc missing energy density. The explanation is based entirely on the internal dynamics of the theories. Two important predictions of the present analysis are: the universe is tending towards a matter dominated state with the dimunition of the dark energy component and the acceleration of the universe, if any, is slowing down with time.
