50. Update on the Dark Matter Crisis…

and are we at the beginning of a major historical paradigm shift?

(by Pavel Kroupa and Moritz Haslbauer, 07th Nov. 2020; 15:00)

There have not been posts on this blog for some time.  The reason is certainly not that the dark matter crisis has gone away.  Quite the contrary — the dark matter crisis, or more generally the cosmological crisis, has worsened and is now quite catastrophic. More on this in the next blog “The Crisis in Cosmology is now catastrophic”. With this contribution we provide an update on recent developments and some philosophical contemplation concerning paradigm shifts.

As a reminder: this blog on the Dark Matter Crisis was started in 2010 through the pressure (which I first resisted) by staff of the journal Spektrum der Wissenschaft in Germany (equivalent to Scientific American) who wanted Marcel Pawlowski (then a PhD student in the SPODYR group in Bonn) and me to blog about the developing crisis. This was related to the research I was involved with at that time leading me to the conclusion that the astronomical data rule out the standard dark-matter-based cosmological model as being relevant for a description of the Universe. This was in tension with my peers. 

In January 2013 the blog was moved, along with all English blogs on Spectrum,  to Scilogs.com. Later this same year there was a temporarily successful attempt by an amateur-science blogger (a sworn MOND enemy) to have the Dark Matter Crisis close down. This failed and the Dark Matter Crisis continued, simply because it’s content is scientifically solid. In 2016 SciLogs.com decided not to host the English Spektrum blogs any longer, and they were transferred to WordPress.com, where they are now. We have not blogged since this last move which had not gone perfectly well technically, with quite a few images having been lost. Just now we repaired most of the losses after some historical digging and with the help of Srikanth Togere Nagesh, MSc student at the University of Bonn. The corrections are continuing, and we are finding that some old links out of the Dark Matter Crisis blogs do not work any longer – we are trying to update them as far as possible and given the limited time available. This has taught me that documentation developed for the internet is fleeting. But we hope the WordPress platform will remain stable. 

Much has happened since the move to WordPress: Indranil Banik, who had contributed the last piece obtained his PhD and is now an Alexander von Humboldt Fellow in the SPODYR group in Bonn. Marcel Pawlowski obtained a Hubble Fellowship and is now a Schwarzschild Fellow at the Leibniz-Institute for Astrophysics in Potsdam, Germany.  Moritz Haslbauer, who is now researching towards his PhD in the SPODYR group at Bonn University, joined our editorial team just now and will publish his first post in the next contribution based on his own research on the Keenan-Barger-Cowie void and the Hubble tension.  He already published two other research papers, one on galaxies lacking dark matter in cosmological simulations (Haslbauer et al. 2019a), and one on ultra-faint dwarf galaxies in cosmological simulations (Haslbauer et al. 2019b), both finding that the observed galaxies are in conflict with the standard model of cosmology (the SMoC).  Concerning myself (PK), I have taken up a joint affiliation with Charles University in golden Prague and have been spending much time travelling there and beyond. I guess the beer, the knedliky and the scientific and cultural importance as well as the open atmosphere at the institutes and the multi-cultural nature and safety of historically extraordinarily beautiful Prague resonate with me. In Bonn, we hosted the large international conference BonnGravity2019: The functioning of galaxies in 2019 and I disjoined myself from the astronomers and have administratively joined a pure-baryonic-physics institute, namely the theory group at the Helmholtz-Institut für Strahlen- und Kernphysik at the University of Bonn. In this context:

Scientists have explorative minds and we know science evolves into new and often unforeseen directions and we should keep our minds open to these in order to allow science to progress rather than stopping scientific advance. It is also important to continue discussions between people working on different ideas without being dismissive. History shows that changes of paradigm can last decades and for those involved it may be impossible at the time to know if they are on the right track.

from Tereza Jerabkova
But are we in a paradigm shift and are we on the right track? The indications for being on the right track come, of course, from constant comparison of the theory one is developing with the observational data, and this blog will be covering this in the future. But are there perhaps some apparently unassociated hints or indications for an ongoing true major paradigm shift?

From the historical record: Very major paradigm changes in world view (religious, scientific) seem to be associated with significant relatively rapid transformations in the arts and with dramatic historical upheavals. Examples of this are (1) the fall of the Roman Empire went along with large-scale change to benign [thou shalt neither lie to nor kill anyone, but love and forgive everyone and all are equal in front of God] monotheism in Europe which improved local social cohesion, removed slavery from Europe and constituted an essentially critical mental step in abstracting the workings of the Universe. This abstraction is critically important because, simply put, until the abstraction there was a deity for every phenomenon (e.g. god of war). (2) The [first] 30 year war in the 17th century which was associated with the Keplerian revolution. In music, the first opera “L’Orfeo” by Monteverdi appeared in 1607. (3) In the early 19th century, the social transformations and associated Napoleonic wars with their large orchestrated battles outside of cities and the “Revolutions of 1848” appear to go in-hand with the development of thermodynamics and electricity as well as the emergence of romantic music and the symphonies by large orchestras (Schumann, Verdi, Wagner, Bruckner, Brahms, Tschaikowsky, and others). (4) The [second] 30 year war in the 20th century (i.e. the first and second world wars combined) happening in-parallel to the Einsteinian/Planckian revolution and being accompanied by the appearance of the twelve-tone technique by Schönberg and the music by the Russian composers Shostakovich, Prokofjew, Stravinsky, and Rachmaninow. (5?) The current world-wide geopolitical developments which appear with rising tensions and increasing dissociation of the power-blocks from each other, the accelerating demographic and potentially negative cultural-religious shifts in Western Europe, the societal changes concerning personal individualism, cancel culture and political correctness, and all of this in combination with the accelerating over-population, climate, micro-plastic-pollution crisis and on-going mass extinction, do seem to be suggestive of a major upheaval which is in the process of unfolding.

The next blog explains why cosmology is in a catastrophic crisis.

Given my affiliation with Charles University, I have been travelling to Prague and beyond frequently and now the CORONA Pandemic has stopped this flying about the planet — I have already written about the first wave and my getting marooned on a beautiful island next to the Strand. Being this time stranded in Bonn without a Strand during the second wave, I have a little more time on my hands I guess. So here we are, back to the Crisis.
