Gravitational lensing observations challenge the necessity of dark matter (DM) in explaining cosmic phenomena. Moti Milgrom, the inventor of Modified Newtonian Dynamics (MOND), argues that MOND can account for these observations without invoking large quantities of DM. His paper, available at arxiv.org/abs/1305.3516, provides a detailed analysis of how MOND addresses gravitational lensing effects. The discussion highlights the ongoing debate between dark matter proponents and MOND advocates regarding the interpretation of astronomical data.
PREREQUISITESAstronomers, physicists, and cosmologists interested in the debate surrounding dark matter and alternative theories like MOND will benefit from this discussion.
