rhertz Posted May 21, 2019 Report Posted May 21, 2019 (edited) I found several articles about the conflict between DM and GTR validity, as it is claimed that MONDsuffices to explain the alleged behavior of the universe, instead the need of DM for GTR to work atcosmological level. Here are some links (mainly from MSM, as I didn't want to spend more time on the search): https://dailygalaxy.com/2018/09/heresy-controversial-alternative-to-general-relativitys-theory-of-gravity-does-not-require-existence-of-dark-matter/ https://physics.stackexchange.com/questions/278387/does-dark-matter-indicate-a-problem-with-general-relativity http://blogs.discovermagazine.com/crux/2018/09/21/the-dark-matter-crisis/ https://www.pbs.org/wgbh/nova/article/do-we-need-to-rewrite-general-relativity/ Any thoughts?

LaurieAG Posted May 21, 2019 Report Posted May 21, 2019 Any thoughts? The ratio of total matter (dm% + om%) over ordinary matter (om%) equals [math]2 \pi[/math] (+/- 1.1% in both the PLANCK and WMAP data sets) using the [math]\Lambda[/math]CDM model so dm is probably redundant on a universal scale as dm = om ([math]2 \pi[/math] - 1) and total m = om [math]2 \pi[/math]. You're not going to get anything better if you model average universal densities. p.s. I always thought [math]\Lambda[/math]CDM was based on a mix of classic Newtonian models and QM not GR. Quote
LaurieAG Posted May 22, 2019 Report Posted May 22, 2019 I invite any of you to find out and read the extense lecture of one of the most kind and genial personalities of the last two centuries, Henri Poincarè,when he addressed the scientific community at a gathering at US in 1905, and how he managed (respectfully) the delicate matter of the need tointroduce structural changes in the whole body of newtonian physics. It's just a masterpiece. My avatar is a Poincarè section of an optical feedback loop. If you look closely you will see that the OS is Windows 98. Here's a quote by Stephen Hawking from "The Nature of Space and Time" from the Isaac Newton Institute Series of Lectures. THESE LECTURES HAVE SHOWN very clearly the difference between Roger and me. He's a Platonist and I'm a positivist. He's worried that Schrodinger's cat is in a quantum state, where it is half alive and half dead. He feels that can't correspond to reality. But that doesn't bother me. I don't demand that a theory corresponds to reality because I don't know what it is. Reality is not a quality you can test with a litmus paper. All I'm concerned with is that the theory should predict the results of measurements. Do you have any links to english language PDF's? Quote
Dubbelosix Posted May 22, 2019 Report Posted May 22, 2019 In my opinion, general relativity cannot be ruled out as a candidate theory for an extension. In other words, dark matter does not disprove or invalid the effects of gravity. A new theory is required in my mind, involving the gravitational binding energy. which for any typical spiral galaxy should equally match the gravitational force of the black hole. It is no coincidence in my eyes, that the black hole at the center of our gravity has the exact same gravitational energy to bind a galaxy together. This is a well-known calculation - I find it curious why scientists never properly found this relationship as significant. There are also rotational effects of spiral galaxies, which when properly undertsood, would cancel out the exact binding energy. When a supermassive black hole is ejected. there is more than enough evidence to show they fly apart and their structures become disorientated due to centrifugal forces. This investigation I made that revealed this was significant enough that a general relativity expert ended up posting the results on his blog page. Quote
Dubbelosix Posted May 22, 2019 Report Posted May 22, 2019 His 1906 published paper "Sur le dinamique du electron" sweeps einsten's theory by the floor. Why? Quote
LaurieAG Posted May 23, 2019 Report Posted May 23, 2019 You may be interested on his June 1905 lecture on relativity, at this link: https://reader.elsevier.com/reader/sd/pii/S1631070517300762?token=E43171BE0D877114B59334C4F9A6471E6B2C1FA8B20F26346CF07D244652C1AAB209DDC32580078E3E495FC11BE32641 Thanks rhertz, I managed to access several relevent pdf's.
