The Rise of Big Bang Models (4) : Lemaître

Sequel of previous post : Dynamical solutions In this series of posts about the history of relativistic cosmology, I  provide an epistemological analysis of the developments of the field  from 1917 to 2006, based on the seminal articles by Einstein, de Sitter, Friedmann, Lemaître, Hubble, Gamow and other main historical figures of the field. It […]

Geometry and the Cosmos (2) : From the Pre-Socratic Universe to Aristotle’s Two Worlds

 Sequel of the previous post Geometry and the Cosmos (1): Kepler, from polyedra to ellipses  The Pre-Socratic Universe Since He [Zeus] himself hath fixed in heaven these signs, The Stars dividing; and throughout the year Stars he provides to indicate to men The seasons’ course, that all things may duly grow.

Galaxies in Flight

This post is an adaptation of a chapter of my book  “The Wraparound Universe” with many more  illustrations.   Galaxies in Flight                      The spawning galaxy in flight is a rainbow trout which goes back against the flow of time towards the lowest waters, towards the dark retreats of duration. Charles Dobzynski (1963) Since the […]

Expansion and the Infinite

This post is an adaptation of a chapter of my book  “The Wraparound Universe” with many more  illustrations. Expansion and the Infinite Space alike to itself that it grows or denies itself Stéphane Mallarmé The Universe is expanding. What does this really mean? Most people imagine an original huge explosion, as the term “big bang” […]

A brief history of space (4/4)

Sequel of the preceding post A Brief History of Space (3/4) : From Descartes to Schwarzschild Cosmology developed rapidly after the completion of general relativity by Albert Einstein, in 1915. In this theory, the Universe does not reduce to a space and a time which are absolute and separate; it is made up of the union […]

My books (3) : Celestial Treasury

Until now I published as an author 30 books in my native language (French), including 14 science essays, 7 historical novels  and 9 poetry collections (for the interested reader, visit my French blog  here. Although my various books have been translated in 14 languages (including Chinese, Korean, Bengali…), only 4 of my essays have been […]

Cosmogenesis (9) : The Big Bang Discovery

Sequel of the preceding post Cosmogenesis (8) : The Nebular Hypothesis In the first quarter of the 20th century cosmology became a distinct scientific discipline, thanks in part to the theoretical advance made in 1915 by Einstein with his theory of general relativity and in part to the revolution in observational techniques which revealed the […]

Cosmogenesis (1) : From Myth to Myth

Introduction Every society has a story, rooted in its most ancient traditions, of how the earth and sky originated. Most of these stories attribute the origin of all things to a Creator -whether god, element or idea. In the Western world all discussions of the origin of the world were dominated until the 18th century […]

As I was also keen on mathematics I followed scientific studies, while continuing in parallel artistic activities. I got my degrees in mathematics and astronomy in Marseille and Montpellier, then my PhD in theoretical astrophysics […]
