  • Abstract

    The rotation curves of spiral and dwarf galaxies, such as NGC 3198 and DDO 154, challenge Newtonian dynamics and motivate theories beyond the dark matter paradigm. Building on the ‎success of Quantum Gravity Theory (QGT) in explaining NGC 3198’s dynamics, the ‎researchers apply QGT to the dwarf galaxy DDO 154 and perform a comparative analysis. ‎Using HI data from *The HI Nearby Galaxy Survey*, the researchers calculate ‎gravitational scale-lengths ( ‎‎) and quantum-corrected velocities (‎ ‎) for both ‎galaxies. For NGC 3198 (‎  ‎) and DDO 154 (‎  ‎), QGT reproduces ‎observed rotation curves with residuals < 5 km/s and reduced chi-square values ‎ ‎. This study confirms QGT’s universality across galaxy masses and ‎morphologies, eliminating the need for dark matter in both spiral and dwarf systems‎.
