On the Accelerated Expansion of the Universe

TL;DR

This paper proposes a quantum entanglement-based hypothesis that explains the universe's accelerated expansion without invoking dark energy, suggesting universe-antiuniverse pairs are created with opposite time flows.

Contribution

It introduces a novel quantum cosmology model where universe acceleration arises from entangled universe-antiuniverse pairs, eliminating the need for dark energy.

Findings

Universe expansion is accelerated under the entangled pair hypothesis

No dark energy or modified gravity is required in this model

Supports a quantum origin of cosmic acceleration

Abstract

If we look from a quantum perspective, the most natural way in which the universe can be created is in entangled pairs whose time flow is oppositely related. This suggests the idea of the creation of a universe-antiuniverse pair. Assuming the validity of this hypothesis, in this paper, we show that the universe expands in an accelerated manner. The same reasoning holds for the anti-universe as well. This idea does not require any form of dark energy as used in the standard cosmological model of ${\Lambda}$CDM or in the modified theories of gravity.
