Arrow Of Time And Reality: In Search Of A Conciliation

What is reality? what is the role of human consciousness in the shaping of such a concept? these questions are as old as mankind and gave rise to the 'mind-matter' dualism which preoccupied so many physicists: Schrodinger, Wigner, etc. This book considers the problem within the realms of contemporary physics, and shows that it could be related so that of ultimate entities. The author develops the viewpoint according to which human thinking activities are fruit of the Cosmos and of its combinatorial activity. Ultimate entities, the bricks out of which out universe is made, could be hidden, as a primordial alphabet, in the foundations of the pyramid of increasing complexity, which seems to unfold as a language and to culminate in the emergence of organized and thinking structures. This is analyzed in the context of cosmological screening and horizon (an expression of our lack of access to totality) where macroscopic and microscopic can mingle, where a unification of interactions and a matching of available arrows of time can take place. This context is also that of quantum evaporation of particle antiparticle like entities, which triggers entropy increase, and of the overlap between General Relativity and Quantum Mechanics. The problem of a (global) origin of the cruising (and evanescent) "now" is considered. A creative principle (reminiscent of the biological mitosis) is also presented which is the generator of the "event" through breaking of temporal symmetry. In this perspective, time-flow is an emergent concept: creation of the World is declined priority on the concept of "coming into existence". Participant to the origin of the World, all (possibly virtual) processes are able to culminate into the phenomenon of consciousness and self-awareness.
