Artistes le dessin d’une mission spatiale propos\u00e9e pour d\u00e9tecter et mesurer les ondes gravitationnelles. (Cr\u00e9dit: NASA via Wikimedia Commons).<\/p><\/div>\n

Des chercheurs associ\u00e9s au Centre d\u2019astrophysique Harvard-Smithsonian ont annonc\u00e9<\/a> avoir d\u00e9tect\u00e9 des ondes gravitationnelles dans le rayonnement de fond cosmologique. Ces ondulations, si elles sont confirm\u00e9es, seraient une preuve solide de la th\u00e9orie de l\u2019inflation qui stipule que l\u2019Univers dans les instants qui ont suivi le Big Bang aurait connu une expansion violente. L\u2019inflation cosmologique est une des th\u00e9ories les plus populaires pour expliquer pourquoi la lumi\u00e8re provenant des d\u00e9buts de l\u2019Univers est si homog\u00e8ne.<\/p>\n
