🌌Modified Newtonian Dynamics (Mond) proposes a new law of gravity that can account for the flat rotation curves observed in galaxies.
🪐Mond suggests the existence of a fundamental acceleration scale, similar to the speed of light, that affects gravity at small scales.
🔬Mond challenges the need for dark matter by offering an alternative explanation for the observed motion of stars in galaxies.
🌌Research is ongoing to understand the limitations and reconcile Mond with observations on larger scales, such as clusters and cosmological structures.
🌌The Gaia mission is providing valuable data on the positions and velocities of stars, enabling detailed analysis of galactic dynamics and testing Mond.
