A l\u2019\u00e9poque d\u00e9j\u00e0, Einstein avait formul\u00e9 une hypoth\u00e8se au sujet de l’\u201d\u00e9cho\u201d de la lumi\u00e8re autour d\u2019un trou noir.<\/p>\n

C\u2019\u00e9tait la premi\u00e8re fois que cette th\u00e9orie \u00e9tait \u00e9mise par un scientifique. Et plus d\u2019un mill\u00e9naire apr\u00e8s, des scientifiques lui donnent raison. Pour info, les trous noirs sont des r\u00e9gions de l\u2019espace-temps connus jusque l\u00e0 pour ne pas laisser \u00e9chapper la lumi\u00e8re du fait de la tr\u00e8s forte puissance de l\u2019attraction de sa gravit\u00e9. N\u00e9anmoins gr\u00e2ce \u00e0 un ph\u00e9nom\u00e8ne que d\u2019aucun qualifie \u201cd\u2019\u00e9trange\u201c, l\u2019extr\u00eame gravit\u00e9 d\u2019un trou noir agit sur l\u2019espace autour de lui, provoquant une d\u00e9formation. C\u2019est cela qui favorise le ph\u00e9nom\u00e8ne qui par lequel la lumi\u00e8re \u00ab fait \u00e9cho \u00bb, en se pliant \u00e0 l\u2019arri\u00e8re de l\u2019objet.<\/p>\n

Des t\u00e9lescopes spatiaux<\/b><\/p>\n

Selon un communiqu\u00e9 de l\u2019ESA, pour leur \u00e9tude, les chercheurs se sont servis de t\u00e9lescopes spatiaux NuSTAR de la NASA et XMM-Newton qui eux appartiennent \u00e0 l\u2019Agence spatiale europ\u00e9enne. Ceci dans le but d\u2019arriver \u00e0 contempler la lumi\u00e8re derri\u00e8re un trou noir qui se trouve \u00e0 800 millions d\u2019ann\u00e9es-lumi\u00e8re dans la galaxie spirale I Zwicky et qui est 110 millions de fois plus gros que notre soleil. En contemplant la trajectoire de la lumi\u00e8re \u00e0 l\u2019arri\u00e8re d\u2019un trou noir, les chercheurs esp\u00e8rent percer le myst\u00e8re des \u00e9v\u00e9nements qui se produisent pr\u00e8s des vortex gravitationnels.<\/p>\n","protected":false},"excerpt":{"rendered":"
