Pierre Thomas Laboratoire des Sciences de la Terre, ENS Lyon Benoît Urgelli ENS Lyon / DGESCO Résumé Calendrier des principaux évènements de l'histoire de l'Univers et de la Terre (depuis le Big Bang ) répartis sur une année. 1 an = 15 milliards d'années, âge estimé du Big Bang ;1 j = 41 millions d'années, 1 s = 500 ans ; 1 milliard d'années = 24 j ; 1 million d'années = 0,6 h = 36 mn.
Notez qu'il y a 3 mois, on a proposé une nouvelle précision pour l'âge du Big Bang (13,7 milliards d'années), alors qu'on proposait avant une fourchette de 12 à 15 milliards d'années ; cela ne change que peu les jours de l'année ci-dessous (exemple le 12 novembre deviendrait le 14 novembre). 1er janvier à 0h : Big bang et formation de l'hydrogène et de l'hélium. Vers la fin janvier : Formation de la Voie Lactée (et des autres galaxies). Les 30 et 31 août : De nombreuses supernovæ explosent près de notre nébuleuse.
