An approach was taken where a hollow sphere was created from point masses and a singular point mass was approached to this sphere. The resulting force on this mass was then plotted against the ...

Newton’s shell theorem asserts that the net gravitational force between a point particle and a sphere with uniform mass density is the same as the force in the situation where the sphere is replaced ...

Making use of Newton’s classical shell theorem, the Schwarzschild metric is modified. This removes the singularity at r = 0 for a standard object (not a black hole). It is demonstrated how general ...

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 ...
