Thank you for your update of the antics of those madcap scientists who continue to very creatively search for “dark matter.” Their frantic quest seems more and more like a comedy of the absurd. Exotic theories such as of “cold dark matter” have now been joined by desperate, contrived fantasies of “self-interacting” and “just warm enough” dark matter. How many more decades are we to look for this mystery material before stopping to reconsider the theories of gravitation that call for this surrealistic stuff? If a theory calls for something to exist and after due diligence this cannot be confirmed, this should reflect poorly on the theory–not necessarily on our powers of observation.
