Proponents of modified gravity address the observation of galaxies that appear to function without dark matter by examining specific cases, such as NGC1277, which demonstrates characteristics of both rotational and pressure support. The ΛCDM model suggests these galaxies typically show a deficit of dark matter, while Modified Newtonian Dynamics (MOND) indicates that their acceleration exceeds the MOND threshold. Notably, galaxies like DF2 and DF4 are considered anomalies, but their interpretations are complicated by factors such as distance and potential misestimation of their proximity. The discussion highlights the importance of relying on scientific papers over popular articles for accurate information. Overall, the conversation emphasizes the ongoing debate about the necessity of dark matter in explaining galaxy behavior.
