Physicists are fighting over 'Cotton gravity' (www.wbur.org)

The halls of science, known for prim propriety and careful debate, are feuding. A new theory of gravity challenges Einstein's general relativity, our current understanding of that thing that keeps our feet on the ground. Physicists are upset.

"Cotton gravity"—named in honor of mathematician Émile Cotton, not fluffy flora—was first posited by Japanese researcher Junpei Harada in 2021. The idea, which modifies general relativity and discounts the theory of dark matter, spurred a surprisingly catty argument on arXiv.org, an open-access website for scientific preprints.

Things got nerdy. And hilarious. Endless Thread explains.
