Expansion of the Universe and Cosmological Redshift

Authors: Daniele Sasso

Astronomical observations show generally a redshift of electromagnetic radiation emitted by stars and galaxies that proves they move away from the observer. There are nevertheless numerous exceptions that prove the existence of a blueshift of radiation and consequently an approach of stars and galaxies. This fact together with a few important anisotropies that are present in the spectrum of the Cosmic Microwaves Background Radiation (CMBR) pose important problems for theories of the Big Bang and of the isotropic expansion of the Universe.
