This book "Quantum Vacuum and the Universe - An Emerging Cosmological Model" is a first, basic and pedagogical presentation, of a new cosmological model based on the working hypothesis that quantum vacuum fluctuations are virtual gravitational dipoles. Our current understanding of the Universe is both, a fascinating intellectual achievement and the source of the greatest crisis in the history of physics. In brief, sophisticated astronomical observations have revealed a series of phenomena that

In galaxies and clusters of galaxies, the gravitational field is much stronger than it should be according to our theory of gravitation and the existing amount of the Standard Model matter (i.e. matter composed from quarks and leptons interacting through the exchange of gauge bosons). The expansion of our Universe is accelerating; contrary to the common sense expectation that gravity must decrease the speed of expansion. Our Universe (with the exception of the quantum vacuum) is dominated by matter; apparently, in the primordial Universe, something has forced the matter-antimatter asymmetry. If it exists, the gravitational impact of the quantum vacuum is many orders of magnitude smaller than predicted by contemporary theoretical physics; a phenomenon known under the name "the cosmological constant problem". The Big Bang model has inherent problems: the problem of the initial singularity and the fact that it contradicts some observations (in particular the observed level of homogeneity and isotropy of the Cosmic Microwave Background). The scientific reaction to the above problems can be summarized in two sentences. First, there is a consensus that these phenomena cannot be explained in the framework of General Relativity and the Standard Model of Particles and Fields. Second, each problem has been considered separately from the others; hence, the number of the invoked ad-hoc hypotheses is equal to the number [...]
