Cosmology, Holography, the Brain and the Quantum Vacuum

摘要

Cosmology, as a science, started at the beginning of the last century with the advent of the Einstein cosmological equations. Based on these equations, the present main stream cosmological model is the well known big-bang (this name unwillingly coined by Fred Hoyle many years ago). Relatively recent additions to this model have been inflation, dark matter and dark energy. This talk presents a smoothly behaved new cosmological model that mainly takes into account the "dark" part of the Universe. We consider it as the background frame, the substrate, of what we see. The inclusion of the holographic principle clarifies the entropy problem that we also apply to the human brain. We take it as an engineering information center. Finally, the inclusion of the quantum vacuum in this scene creates an important challenge, an opportunity for future research in the knowledge of the Universe.
