Euler-Poisson-Newton approach in Cosmology

Abstract: This lecture provides us with Newtonian approaches for the interpretation of two puzzling cosmological observations that are still discussed subject : a bulk flow and a foam like structure in the distribution of galaxies. For the first one, we model the motions describing all planar distortions from Hubble flow, in addition of two classes of planar-axial distortions with or without rotation, when spatial distribution of gravitational sources is homogenous. This provides us with an alternative to models which a… Show more

“…18 The anthropic problem turns out to be unfounded since the respective curves of λ and Ω intersect at an abscissa a ∼ 0.75 which does not correspond to a peculiar situation within the interval ]0, a• = 1], see e.g. [23]. Only if Λ > 0 this problem can be addressed with a formulation including the future by using the conformal time, which turns out to be bounded, and the present time does not show any peculiar value, which turns out to be located nearby the asymptotical value.…”
