The discussion centers on the relationship between WIMP-nucleon cross sections and dark matter particle mass, specifically referencing a cross section of 1.2x10-47 cm2 at 1 TeV/c2. It concludes that while there is a correlation between cross section and mass, no universal formula applies to all processes. The analysis of direct dark matter detection experiments, such as LUX, indicates that heavier dark matter particles require a lower production cross-section due to the finite amount of dark matter in the universe. Additionally, the discussion highlights the complexities of modeling dark matter interactions and the challenges in distinguishing signals from background noise in experimental data.

As a matter of fact I also got into an argument with him about an error, and while he acknowledged the error privately, he didn’t correct it in his blog.Vanadium 50 said:Ethan Siegel is not a reliable source. On multiple occasions he has made an error, I reported it to him, he acknowledged the error, and then didn't correct it. He writes "sciency entertainment" not science.
In any event, I think this thread can be closed. You asked a question, got an answer, and did not accept the answer. What purpose is there in going around again and again and again?
