Vers l'infiniment grand from Coursera

Partez à la découverte de l'infiniment grand, en compagnie de physiciens et de physiciennes qui vont vous faire découvrir l'Univers aux distances les plus grandes connues à ce jour et les outils scientifiques utilisés pour l'étudier. Vous comprendrez ce que les scientifiques ont pu apprendre sur l'histoire et la structure de l'Univers, ses composantes, et comment ils ont pu accumuler ces observations sur les étoiles, les galaxies, les amas de galaxies, et l'Univers dans son ensemble.

Ce cours en français fait partie du MOOC "Voyages de l'infiniment grand à l'infiniment petit", conçus par des physiciens et des physiciennes du Labex P2IO (Physique des 2 Infinis et des Origines, IPP et Université Paris-Saclay) regroupant des laboratoires de physique de l'infiniment grand et de l'infiniment petit situés à Orsay et Saclay. Les différents parcours de ce MOOC vous montreront les connaissances et les énigmes de l'infiniment grand et de l'infiniment petit, les relations que ces deux infinis entretiennent, et les liens de ces découvertes avec la société :

Syllabus

Les notions de base

Ce module présente les grands concepts liés à notre compréhension actuelle de l'Univers, de sa structure et de son évolution. Il aborde également les différents messagers qui nous fournissent des informations sur l'infiniment grand. Il discute aussi les "briques de base" des structures de l'infiniment grand : les étoiles.

Les forces fondamentales

Ce module s'intéresse aux deux grandes forces fondamentales nécessaires pour décrire notre Univers sur de grandes échelles, à savoir la gravitation et l'interaction électromagnétique. Il se focalise en particulier sur la description contemporaine de la gravitation, à savoir la théorie de la relativité générale, et les différents tests qu'elle a subis.

L'Univers aux échelles les plus grandes

Ce module s'intéresse aux grandes structures du cosmos : comment les étudie-t-on ? comment sont-elles nées à partir de l'Univers primordial ? que pouvons-nous apprendre sur la composition de l'Univers en les étudiant ? Nous savons ainsi décrire notre Univers de façon remarquablement précise, à condition d'introduire des composantes inattendues, l'énergie sombre et la matière sombre.

L'observation de l'Univers

Ce module s'intéresse aux projets actuels et à venir pour mieux observer le ciel. D'une part, les satellites d'observation ont ajouté des informations précieuses sur notre Univers, impossible à obtenir autrement. D'autre part, des campagnes d'observation, sur terre ou dans l'espace, sont en préparation pour améliorer notre connaissance de l'infiniment grand.
