Description
I have recently proposed a slight non-relativistic modification of the Newton law of universal gravitation [1,2]. Accordingly, the 1/r Newton
field is following the motion of the source with a certain
laziness characterized by the delay time τ_G. The background motivation came from
quantum foundational
speculations [3,4] yielding an estimate τ_G ∼ 1ms. Surprisingly, in the simplest model of lazy Newton force, a 1ms
delay predicts significant effect on the notorious 5th digit of the Newton constant G determined in a Cavendish experiment despite its poor
time-resolution.
In 2014, Yang, Miao and Chen advocated independently the concept of finite emergence
time of gravity [5], along with a cautious analysis
of cosmologic, celestial and laboratory
evidences, suggesting stringent upper bounds on τ_G at low frequency cosmological
phenomena and
weaker upper bounds from laboratory experiments at higher frequencies, mentioning my 1ms in the middle. I'll briefly discuss their work.
