Galaxies are huge physical systems having dimensions of many tens of thousands of light years. Thus any change at the galactic center will be noticed at the rim only tens of thousands of years later. Those retardation effects seem to be neglected in present day galactic modeling used to calculate rotational velocities of matter in the rims of the galaxy. The significant differences between the predictions of Newtonian theory and observed velocities are usually explained by either assuming dark…

TLDR
It is demonstrated, using a detailed model, that one can explain the radial velocities of galactic matter in the M33 galaxy without postulating dark matter and is perfectly consistent with the current observational knowledge of galactic and extra galactic material content and dynamics.

The standard big bang cosmological model and the history of the early universe according to the grand unified theories of strong, weak and electromagnetic interactions are summarized. The
Rotational properties of 21 SC galaxies with a large range of luminosities and radii, from NGC 4605 /R = 4kpc/ to UGC 2885 /R = 122 kpc/
For 21 Sc galaxies whose properties encompass a wide range of radii, masses, and luminosities, we have obtained major axis spectra extending to the faint outer regions, and have deduced rotation

THE GRAVITATIONAL ORIGIN OF THE DISTINCTION BETWEEN SPACE AND TIME
To the ordinary human it is obvious that there is a clear distinction between the spatial dimensions, in which one can go either way, and the temporal dimension, in which one seems only to move

TLDR
The first step of this program consists in securing more complete data on the number and the distribution of groups of ne Bulae containing two, three or more members up to clusters of many hundred nebulae.

It is stated in many text books that the any metric appearing in general relativity should be locally Lorentzian i.e. of the type ημν=diag (1,−1,−1,−1) this is usually presented as an independent
