Forthcoming book proposes Newtonian GR model June 1

David Griffin is promoting a self-published-sounding cosmology book called *It’s Newtonian General Relativity*, with a stated release date of June 1. A May 18 post from the X account @NGR_Griffin said the book proposes a framework intended to unite Newtonian physics and Einstein’s General Relativity. A YouTube description tied to the same branding identifies Griffin as the author and calls the model “Newtonian General Relativity,” or NGR. ### What exactly has been announced? A May 18 social-media post from @NGR_Griffin said Griffin’s book is due June 1 and described it as a unifying approach between Newtonian and Einsteinian gravity. The post itself was not fully machine-readable in fetched web results, but the account, title and release timing are consistent with other public materials tied to the same project. (youtube.com) A YouTube video published under the “Newtonian General Relativity (NGR)” branding says, “In *It’s Newtonian General Relativity*, independent thinker David Griffin presents NGR,” and describes the work as a “complete scalar-based cosmological model.” The same description says the book is “coming soon” and directs readers to @NGR_Griffin for updates and excerpts. (youtube.com) ### Who is David Griffin in these materials? A YouTube channel for “Newtonian General Relativity (NGR)” identifies the speaker as David Griffin and says, “I’m David Griffin, a blue-collar worker who built Newtonian General Relativity (NGR).” The available public material does not show an institutional affiliation, university appointment or peer-reviewed publication record for the model in the sources reviewed here. (youtube.com) The project’s public-facing language presents Griffin as an independent author rather than a university-based physicist. That distinction matters because, in the material currently available, the announcement is for a forthcoming book and social-media rollout, not for a paper accepted by a major physics journal. ### What does the proposed model claim to do? (youtube.com) The project materials say NGR “unites Newtonian physics with General Relativity using a single universal constant” identified there as the “Griffin Constant.” The same description says the model aims to account for galactic rotation curves, gravitational lensing, the Hubble tension and other cosmological observations. (youtube.com) The promotional text also says the model does not require dark matter, dark energy or inflation. Those are the project’s claims in its own words; the reviewed sources do not show outside validation, published replication or endorsement from established physics institutions. ### Is there evidence yet of scientific review? The available web evidence points to a social-media and video rollout, not a formal scientific publication. (youtube.com) Search results reviewed for the book and model surfaced YouTube materials and the author-branded channel, but did not surface a journal article, university press listing or major bookseller entry that independently documented the work. That means the announcement can be reported as a forthcoming book proposal, but not as an established advance in mainstream physics. The public record currently available is the author’s own description of what the model is meant to explain. ### What should readers watch next? June 1 is the date attached to the release in the project’s promotional material. (youtube.com) The most direct next checkpoints are whether the full book becomes publicly available on that date and whether Griffin or outside researchers publish detailed derivations, references or formal responses afterward.
