Note on Possible Emergence Time of Newtonian Gravity

TL;DR

This paper discusses the potential emergence time scale of Newtonian gravity, suggesting it could be around 1 millisecond, which might be tested experimentally, despite current evidence lacking sufficient resolution.

Contribution

It introduces the concept of an emergence time scale for gravity and proposes a testable experimental approach based on extrapolations from wave function collapse theories.

Findings

Experimental evidence has poor time resolution for gravity's immediate creation.

A possible emergence time scale of ~1 ms is proposed.

The concept can be tested with reachable experiments.

Abstract

If gravity were an emergent phenomenon, some relativistic as well as non-relativistic speculations claim it is, then a certain emergence time scale tau_? would characterize it. We argue that the available experimental evidences have poor time resolution regarding how immediate the creation of Newton field of accelerated mass sources is. Although the concrete theoretical model of gravity's `laziness' is missing, the concept and the scale tau_? ~ 1ms, rooted in an extrapolation of spontaneous wave function collapse theory, might be tested directly in reachable experiments.
