Abstract(s) :

(Anglais) The idea of the talk is, in a first time, to make a quick (and therefore non exhaustive) review of the main conceptions of the notion of aether through history of science. More precisely, the idea would be to review succinctly how the concept of aether was "physically" thought, why and how it was introduced at different stages of the development of physical theories. This review will be made on purpose : In a second time, I will use this review to show how the situation in physics before the 20th century parallels the current one, especially for questions related to dark matter and dark energy. If time permits, I will briefly discuss some attempts to solve these puzzles, focusing on the likeness in the ways of considering both the problem and the solution. My point of view would then be the one of a physicist trying to think as a (highly amateur !) philosopher of science. This structure for the talk is aimed to give raise to debates (... maybe struggles ?) and will hopefully give us the opportunity to compare fundamental conceptions from different areas.
