描述.This book provides a mathematical and numerical analysis of many problems which lead to paradoxes in contemporary cosmology, in particular, the existence of dark matter and dark energy. It is shown that these hypothetical quantities arise from excessive extrapolations of simple mathematical models to the whole physical universe. Written in a completely different style to most books on General Relativity and cosmology, the important results take the form of mathematical theorems with precise assumptions and statements. All theorems are followed by a corresponding proof, or an exact reference to the proof..Some nonstandard topics are also covered, including violation of the causality principle in Newtonian mechanics, a critical mathematical and numerical analysis of Mercury‘s perihelion shift, inapplicability of Einstein‘s equations to the classical two-body problem due to computational complexity, non-uniqueness of the notion of universe, the topology of the universe, various descriptions of a hypersphere, regular tessellations of hyperbolic spaces, local Hubble expansion of the universe, neglected gravitational redshift in the detection of gravitational waves, and the possible dis

Identification of transplanted material is often difficult if dissociated cells are used, particularly if the donor cells are migratory, or are trans-planted into fetal or neonatal hosts.

Its major advantages, compared to the earlier studies of transplanting solid pieces of fetal tissue into cortical cavities overlying the caudate-putamen (CPU) or lateral ventricle (.; .), have been the ability to graft to intraparenchymal target sites with less traum

In many phylogenetically lower animals, massive axonal regeneration occurs and often results in some degree of functional restitution, despite the presence of scar formation within the site of injury (Bernstein and Bernstein 1967), but in mammalian forms regene

Therefore, neurons that die as a result of regressive processes can only be replaced by implantation after harvesting from an external source.
