Abstract :

An irreversible phenomenon are characterized by a monotonic parameter of (universal) time t. According to philosophers, time cannot be defined without a reference to itself. We contest this because time is also a monotonic function of any irreversible parameter, from which time can be defined as well. Since universe expansion is a commonly accepted irreversible process, the average density of the universe ρ is a good candidate. Therefore we can define t = f (ρ ) . Then the choice of the monotonic (and continuous) function f is open. In the absence of additional requirement, we can defnine A time 1t = f (ρ ) and another time [ ] 2 1T = f f (ρ ) Additional requirements will come from some physical hypothesis, such as inertia priniciple. It is a physical axiom, hopefully coherent with our everyday intuition and vocabulary. Every alternative definition of a time will lie on different physical rules and lead to different physical equations. Simpler than defining time is switching from one time to another. One can chose such a tranformation f2 (we will say mapping) in order that the impact on our equations is minimal at the human scale, which means in order that the two times t and T coincide over the short period of our existence. I will propose such a tranformation. It has amazing effects: For instance, within time T , the age of the universe becomes infinite. Beside a playful attempt to introduce some doubt in the apparently safest conceptual areas, the goal of this talk is to get the feedback of experts in astrophysical and comological models about the connexions they can infer between such time manipulation and the fundamentals of their models.

Biography :

Dominique Ausserré has completed his PhD in Collège de France, Paris and has been Visiting Scientist in IBM, San Jose. He is a co-starter of a soft matter lab in Institut Curie, Paris, and then moved to Le Mans University in 1991. He is Research Director in CNRS, France, and worked in the fields of optics, polymer and statistical physics, material science, capillarity and surface physical chemistry, now moving towards biology and healthcare oriented technological developments. He invented self-assembled nano-composite materials made of nanoparticles and diblock copolymers, self-assembled polar lamellar materials named ferrochemicals, and the SEEC and BALM optical techniques. He was Co-founder of two startups: Nanoraptor and Watch Live.
