Abstract

We present a method to investigate relativistic effects arising from large masses. The method is non-perturbative and employs a mean-field approximation and gravitational lensing. Using this method and a basic model of disk galaxy, we find that relativistic corrections to the rotation curves of disk galaxies are significant at large galactic radii. The model predicts a strong correlation between the inferred galactic dark mass and the galactic disk thickness, which we verified using two separate sets of observational data.

    • It doesn't, and the problems have only become more problematic over time, but it's the least bad hypothesis that's broadly accepted. I suspect a generational succession is required for new paradigms to be contemplated. There are many researchers proposing simpler, novel, and…

    • I'd like to see more work done with investigating field self-interaction. This 2020 paper by Alexandre Deur is very interesting. "[W]e find that relativistic corrections to the rotation curves of disk galaxies are significant at large galactic radii." "Relativistic corrections…
