Galaxy pairs defy dark matter dominance: systemic anomalies challenge ΛCDM cosmology in Fornax Cluster outskirts
Original framing: “Possible dark matter-deficient twins discovered in the Fornax Cluster” — Phys.org
The discovery of FCC 224 and FCC 240 challenges the ΛCDM model’s prediction that galaxies should contain significant dark matter halos. Observational evidence from these galaxies suggests that baryonic matter alone can explain their dynamics, contradicting the model’s foundational assumptions. This raises questions about the model’s predictive power and the need for alternative theories, such as Modified Newtonian Dynamics (MOND) or emergent gravity, which do not require dark matter.
The discovery of FCC 224 and FCC 240 in the Fornax Cluster is not merely an astronomical anomaly but a systemic challenge to the ΛCDM model’s hegemony in cosmology.
This paradigm, which assumes dark matter’s ubiquity, has been reinforced by institutional power structures that prioritize its predictions over alternative theories like MOND or emergent gravity. The anomalies in these galaxies echo historical precedents of cosmological crises, such as the rejection of steady-state theory, suggesting that the ΛCDM model may be culturally contingent rather than universally necessary. Cross-cultural perspectives, from Indigenous Australian cosmologies to Hindu cyclical models, further highlight the limitations of a dark matter-centric narrative, offering relational and spiritual frameworks that do not rely on a single dominant 'missing mass.' Moving forward, a systemic solution requires dismantling the institutional biases that marginalize alternative theories and integrating marginalized voices—both within science and across cultures—into a more inclusive cosmological discourse. The future of astrophysics may lie not in clinging to dark matter’s dominance but in embracing the plurality of evidence and the wisdom of diverse knowledge systems.
