Discours sur l’origine de l’univers

D’où vient l’univers ? Et d’où vient qu’il y a un univers ? Irrépressiblement, ces questions se posent à nous. Et dès qu’un discours prétend nous éclairer, nous tendons l’oreille, avides d’entendre l’écho du tout optimum sign : les accélérateurs de particules vont bientôt nous révéler l’origine de l’univers en produisant des « mammoth bang sous terre » ; les données recueillies par le satellite tv for pc Planck nous dévoiler le « visage de Dieu » ; certains disent même qu’en vertu de l. a. loi de los angeles gravitation l’univers a pu se créer de lui-même, à partir de rien…
Le grand dévoilement ne serait donc devenu qu’une affaire d’ultimes petits pas ? Rien n’est moins sûr… automobile de quoi parle l. a. body quand elle parle d’« origine » ? Qu’est-ce que les théories actuelles sont réellement en mesure de nous révéler ?
À bien les examiner, les views que nous offre l. a. cosmologie contemporaine sont plus vertigineuses encore que tout ce que nous avons imaginé : l’univers a-t-il jamais commencé ?

To Silliman, for all his deep religious faith, it was obvious that the geological phenomena he learned about were not the result of six days' effort even by the most omnipotent deity. But the fact that the developments in the earth's crust must have required countless thousands of years never disturbed him. H e was able, in his own mind, to reconcile all this slow process with the existence of a Creator—much as today's liberal church people have done. But such was the prevailing mood of those days that it was only the constant reiteration of his religious belief that made it possible for him to continue his extracurricular lectures.

Just before starting work at the Academy, Henry spent a few days in N e w York. One of his biographies has suggested that he may have gone there for relaxation—a last good time before he assumed his arduous duties in Albany—or, perhaps, simply for sightseeing. But Henry's idea of a good time differed from that of most young men. For him, there were more instructive things in the big city than the taverns or the theatres, and Joseph was seldom diverted from his passionate search for knowledge. The New York sight that most stirred him was an electromagnet made by William Sturgeon of England—a prized possession of one of Henry's acquaintances.

He then tried letting a current run through various lengths of wire. A few excerpts from his own record of the experiment show his result. 49 Exp. 8. Each wire of the horse-shoe was soldered to the battery in succession, one at a time; the magnetism developed by each was just sufficient to support the weight of the armature, weighing 7 lbs. Exp. 9. Two wires, one on each side of the horse-shoe, were attached; the weight lifted was 145 lbs. . Exp. 14. When all the wires (nine in number) were attached, the maximum weight lifted was 650 lbs.
