Abstract
Based on well known photometric rules for the number of galaxies as function of the distance in Mpc we model the so called “Great Wall” which is visible on the Cosmicflows-2 catalog. The gravitational field is evaluated at the light of the shell theorem and a finite value for the gravitational field is numerically derived.
Highlights
Before to start we briefly review the Hubble law, after [1], which is a linear relationship between expansion velocity and distance in
[11] states that “If to every point of a spherical surface there tend equal centripetal forces decreasing in the square of the distances from those points, I say, that a corpuscle placed within that superficies will not be attracted by those forces any way” or more “The gravitational field inside a uniform spherical shell is zero” [12] [13] [14]
The masses do not disappear with distance and the above value of the box allows processing a complete sample of galaxies
Summary
Before to start we briefly review the Hubble law, after [1], which is a linear relationship between expansion velocity and distance in. The original Hubble’s law was based on ≈20 galaxies of which was known the distance and the velocity; in the last years the number of catalogs for galaxies with redshift available for public downloading has progressively grown. This huge amount of data allows setting up critical tests between different theoretical models over the various aspects of the Large Scale Structures.
