Dark energy and quantum vacuum fluctuations

TL;DR

This paper proposes that quantum vacuum fluctuations, rather than the vacuum energy itself, cause space-time curvature akin to dark energy, with calculations aligning with cosmological data.

Contribution

It introduces a model where quantum fluctuations induce dark energy effects, offering an alternative explanation consistent with observations.

Findings

Quantum fluctuations can produce space-time curvature similar to dark energy.

Calculations within quantized gravity align with cosmological observations.

Vacuum expectation value of energy-momentum is zero, but fluctuations generate observable effects.

Abstract

It is suggested that the vacuum expectation of the quantum vacuum energy-momentum is zero, but quantum fluctuations give rise to a space-time curvature equivalent to that of a cosmological constant or dark energy. Calculations within quantized gravity, following a few plausible hypotheses, provide results compatible with cosmological observations.
