The discussion revolves around critiques of the concept of dark matter, specifically addressing a satirical take that questions its scientific validity. Participants explore the theoretical underpinnings of dark matter, its necessity in cosmological models, and the potential for alternative explanations, including modified gravity theories.
Participants generally do not reach a consensus, with multiple competing views on the validity and necessity of dark matter versus alternative theories. The discussion remains unresolved, reflecting a range of opinions and ongoing debates in the field.
Limitations include the dependence on current observational data and theoretical frameworks, as well as the unresolved nature of alternative theories to dark matter. The discussion highlights the complexity of the issues involved and the need for further research.
Even without supersymmetry for specific suggestions, I don't see how extra particles are in any way unexpected regardless.twofish-quant said:The trouble with these extra particles is that they all come from supersymmetry, and there is not the slightly shred of experimental evidence in favor for supersymmetry, and the theoretical reasons for supersymmetry aren't IMHO that compelling. Replacing one unknown particle with a bizilion unknown particles doesn't see to me to be that much of an improvement.
