The texts behind the ideas.

Start with the introductory essay. The four research articles below then provide the arguments, equations and their limitations. They are preprints: texts made public before any subsequent peer review. The illustrated essay remains in French; the four research preprints are available below in faithful English editions.

About Alexandre Leroy

An entrepreneur, software developer and independent researcher, Alexandre Leroy explores the connections between the philosophy of time and physical formalization.

My starting point

I have had several flashes of intuition about the deep nature of reality. The search for unification, anomalies and still-unexplained phenomena have guided my exploration. Probabilistic presentism took shape in my mind because I found in it a way of addressing many of these questions within a single framework.

My inspirations

They range from the sciences and established theories of fundamental physics to Indian and Chinese philosophies and other traditions of thought, including Vedānta, Shaivite Tantra, Taoism and Buddhism.

My method

Brainstorming with AI around my intuitions is one of my working methods: it helps me explore avenues and clarify my ideas. I am also committed to rigorously preserving compatibility with the major existing physical theories.

Intuitions, inspirations and exchanges feed the research; its validation requires formulating the proposals, examining their consistency and confronting them with observations.

What do you think?

What seems clear, debatable or difficult to understand? Questions, objections and examples are welcome. You do not need to master the equations to join the discussion.

A deposit is not a validation.

The V1.1 introductory essay offered here has not yet been deposited on Zenodo.

The preprints make the work available to read and cite. Their presence on Zenodo does not mean that the model has been experimentally validated or peer-reviewed.

This site distinguishes the ontological framework, interpretations, working formulations and physical extensions to be tested.
