The Fate of MOND: Wide Binaries as the Ultimate Test
Wide binary stars are challenging the theory of gravity and the need for dark matter. General relativity, along with normal matter, cannot explain the evolution of the universe without dark matter, which has not been directly observed. Modified Newtonian Dynamics (MOND) proposes an adjustment to Newton's second law to explain galaxy movement without dark matter. However, recent data from wide binary stars suggests that any modified gravity theory must rely on scale and length rather than acceleration, potentially marking the demise of the MOND model.
