De plus, ce mouvement serait en acc\u00e9l\u00e9ration. Cette th\u00e9orie sugg\u00e8re que les objets s\u2019\u00e9loignent les uns des autres, mais elle t\u00e9moigne \u00e9galement de l\u2019agrandissement de l\u2019espace lui-m\u00eame.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Le d\u00e9but de la fin<\/h3>\n\n\n\n<p>Selon une r\u00e9cente \u00e9tude, une mod\u00e9lisation produite par des cosmologues montre que cette expansion va ralentir et \u00e9ventuellement cesser. Par la suite, l\u2019Univers entrerait dans un processus de lente contraction. Les scientifiques estiment que la p\u00e9riode d\u2019acc\u00e9l\u00e9ration prendra fin dans environ 65 millions d\u2019ann\u00e9es. Toutefois, la contraction de l\u2019Univers prendrait des milliards d\u2019ann\u00e9es.<\/p>\n\n\n\n<p>Source :&nbsp;PNAS<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Gr\u00e2ce \u00e0 Edwin Hubble, cette th\u00e9orie a fait du chemin.
