  But also about other claims from the Ekeberg's article (who, as I see, is a "a philosopher of science"): https://www.forbes.com/sites/startswithabang/2018/07/26/theres-a-debate-raging-over-whether-dark-matter-is-real-but-one-side-is-cheating/ https://www.forbes.com/sites/startswithabang/2018/07/26/ther... "There's A Debate Raging Over Whether Dark Matter Is Real, But One Side Is Cheating" Careful reader of Ekeberg's article can both recognize that the article claims are inspired by the claims of the "cheating" side but also that where he writes his own he completely fails on physics. I.e. if one side is cheating, he'd be a third side, the one that's completely unscientific: even the physicists that develop theories that compete with dark matter would not write what Ekeberg wrote: "Another recent probe found galaxies inconsistent with the theory of dark matter, which posits this hypothetical substance to be everywhere. But according to the latest measurements, it is not, suggesting the theory needs to be reexamined." It's plain nonsense. The reason: https://www.forbes.com/sites/startswithabang/2019/01/16/mysterious-galaxy-measured-exquisitely-and-contains-no-dark-matter-at-all/ https://www.forbes.com/sites/startswithabang/2019/01/16/myst... "Ironically, the discovery of a galaxy without dark matter — amidst a sea of galaxies that require huge amounts of it — helps prove the validity of the dark matter-rich picture of the Universe. Only if normal matter can be separated out from the dark matter and left to form its own structures would such a galaxy be possible." We even have the pictures where the galaxies and dark matter aren't at the same place, totally the opposite of Ekeberg's "everywhere" strawman claim, and exactly that opposite was always treated as the biggest support for dark matter: https://www.forbes.com/sites/startswithabang/2017/11/09/the-bullet-cluster-proves-dark-matter-exists-but-not-for-the-reason-most-physicists-think/ https://www.forbes.com/sites/startswithabang/2017/11/09/the-... Once I've reached that strawman claim, I've checked what the profession of Ekeberg is. I openly admit his uncritical bias just confirmed my own bias about that profession.
