The Dark Energy and the Fate of Universe
Mian Wang

TL;DR
This paper explores the role of dark energy in the universe's future evolution within scalar-tensor cosmology, showing it dominates energy density and leads to a specific expansion rate.
Contribution
It introduces a scalar-tensor cosmology model where dark energy is primarily from a gravitational scalar field, predicting a power-law expansion of the universe.
Findings
Dark energy constitutes about 70% of the universe's energy density.
Future universe will expand as a power law with exponent approximately 1.3.
Dark energy is mainly from the gravitational scalar field.
Abstract
Recent observations confirm that our universe is flat and consists of a dark energy component . This dark energy is responsible for the cosmic acceleration as well as determines the feature of future evolution of the universe. In this paper, we discuss the dark energy of universe in the framework of scalar-tensor cosmology. It is shown that the dark energy is the main part of the energy density of the gravitational scalar field and the future universe will expand as .
