Sure, but the origin of this preprint is in the stochastic-classical/uncertain-quantum "postquantum-classical" theory the Oppenheim group is working on. Their theory is premised on a weakening of the gravitational interaction at short distances (it's "asymptotically free" and thus renormalizable) compared to perturbative quantum gravity (which is non-renormalizable by power counting). However, they discovered that the gravitational interaction in their theory can be too strong. More technically, in their diffusion limit they extract a different scalar potential than from GR's weak field…

That's an older paper that was initially uploaded in 2018 and revised last year. The preprint under discussion is at https://arxiv.org/abs/2402.19459

Why should I? I am dedicating my life to my biggest passion, which is not cosmology. If one does commit themselves to their passion they should strive to push the field further forward, not stagnate it. It can be done. https://arxiv.org/abs/2402.19459
