Gravity and Information: Putting a Bit of Quantum into GR

TL;DR

This paper explores how quantum properties of the energy-momentum tensor can explain dark matter and dark energy phenomena within general relativity, linking quantum information to gravitational effects.

Contribution

It introduces a novel operator and distinguishes gravitational from non-gravitational information, revealing quantum effects that influence cosmic and local gravitational dynamics.

Findings

Dark matter and dark energy behaviors emerge from quantum aspects of the energy-momentum tensor.

The operator X^2d^2/dX^2 + 2Xd/dX is significant in analyzing quantum effects in gravity.

The Sun-Earth distance increases by 11 cm per year due to changes in gravitational information.

Abstract

It is shown that quantum aspects of the energy-momentum tensor reveal dark matter and dark energy behavior for general relativity. Special meaning is assigned to the operator X^2d^2/dX^2 +2Xd/dX, for any field X that is part of the energy-momentum tensor, and to the distinction between information on gravitational and non-gravitational effects. Changes in such information cause the Sun-Earth distance to increase by 11 cm/yr.
