We are so accustomed to Newtonian law of gravitation, which actually works very well up to Mpc distances, that the news of this law being NOT universal may seem astonishing. However, it has been recently strictly proven that a physical quantity in GR/cosmology, which may be associated with the gravitational potential, demonstrates Yukawa behavior starting from Gpc scales. In short, the universal gravitation at arbitrary distances should be described by Yukawa law.

Albert Ripple (“bort”)Propriétairethat's really interesting, because relativistic gravity is often said to still be a classical force, and by classical they generally mean newtonian rather than non-quantum.24 juil. 2016- Albert Ripple (“bort”)Propriétairei'm gonna move your original post to the right category, the same one as this post24 juil. 2016
- Albert Ripple (“bort”)Propriétaireso, i'm presuming your abstract in the page you linked in this reshare is a more technical and complicated way of saying the content of your original post?24 juil. 2016
- Albert Ripple (“bort”)Propriétaireok, i've looked up the question of yukawa vs newton, and it seems that, as late as the end of last year (http://motherboard.vice.com/read/this-space-mission-could-upend-our-basic-notions-of-newtonian-gravity), that question is still not settled, so i'm moving this and your original post to the debate center.24 juil. 2016

+Albert Ripple Dear Albert, yes, the link refers to the recent publication in The Astrophysical Journal, devoted to a convincing mathematical proof in the framework of the concordance cosmological model and discrete presentation of matter sources.24 juil. 2016- Regarding the mentioned article "This Space Mission Could Upend Our Basic Notions of Newtonian Gravity", it is about the Yukawa-type admixture to the Newtonian potential rather than about replacement of the Newtonian potential by the pure Yukawa one. In addition, typical scales are different. The proposed spacecraft would probe gravity at distances of the order of the Solar System dimensions, while homogeneous cosmological background effectively screens Newtonian attraction at much larger, Gpc-distances.25 juil. 2016
