From the Arrow of Time to the Arrow of Life
Earth, Moon, and Planets, 2006Astrobiology, like many (but not all) sciences, must take into account questions of the “Why?”, “Where?”, “How?” and “When?” type. In this introductory chapter, we explain why, in this book, we will only consider two of these questions that are, moreover, deeply interrelated. Chronology is by definition related to the “when?” question but as soon as we

, 1983 Space and time are the most fundamental ideas of the scientist’s picture of the world, and also of the language in which we all describe our thoughts and sensations. We use the concepts of space and time to “relate” ourselves to world phenomena that we and other people observe and to “verify” that what other people report to us as “their observations ...

Physical Review D, 1985
The usual proof of the CPT theorem does not apply to theories which include the gravitational field. Nevertheless, it is shown that CPT invariance still holds in these cases provided that, as has recently been proposed, the quantum state of the Universe is defined by a path integral over metrics that are compact without boundary. The observed asymmetry

On the cosmological arrow of time
2023The cosmological arrow of time is defined by the initial conditions of the Universe and its subsequent expansion. Wetterich [1] has proposed an alternative picture of the expanding Universe where the observed cosmological redshift can equivalently be viewed as originating from the increase in mass of particles over time. In this article, we address the
