The Problem of Galaxy Rotation Curves
The observed flat rotation curves, where stars maintain high velocities at large galactic radii, contradict the Newtonian predictions. This anomaly has presented a significant challenge to our understanding of gravity and the distribution of visible matter in galaxies.
The prevailing explanation invokes dark matter, a non interactive form of matter that permeates galaxies, providing the additional gravitational pull needed to explain the observations. However, despite extensive searches, dark matter remains undetected.
Dark Matter visualization
According to dark matter models, galaxies reside within vast, unseen halos that extend well beyond their visible regions, providing the gravitational force required to account for the high orbital velocities observed at large radii.
Mezzi effect visualization
The mezzi effect is a relativistic observational effect that causes galaxies to appear compressed. This effect makes distant stars appear closer to the center than they truly are, which distorts the inferred distances and leads us to miscalculate their orbital speeds. By accounting for this distortion, the Newtonian model results align with observed flat rotation curves.
