L\u2019astrophysicien anglais avait alors e\u0301nonce\u0301 que la surface totale des trous noirs ne peut qu\u2019augmenter au fil de leur existence, en de\u0301pit de l\u2019e\u0301mission d\u2019ondes gravitationnelles qui tendraient pluto\u0302t a\u0300 la diminuer. Cette pre\u0301diction restait the\u0301orique. L\u2019e\u0301ve\u0301nement GW250114, enregistre\u0301 en janvier 2025, a livre\u0301 un signal si net qu\u2019il a permis de la ve\u0301rifier de visu, ce dont l\u2019astrophysicien n\u2019aurait sans doute pas ose\u0301 re\u0302ver il y a cinquante ans, lorsque l\u2019existence me\u0302me des trous noirs restait hypothe\u0301tique.<\/p>\n

Une confiance de 99,999 %<\/b><\/p>\n

Deux astres de 30 a\u0300 40 masses solaires, d\u2019environ 240.000 km2, ont ainsi fusionne\u0301 pour former un trou noir final de 400.000 km2 \u2013 une augmentation conforme au the\u0301ore\u0300me de Hawking, ve\u0301rifie\u0301 ici avec une confiance de 99,999 %.<\/p>\n
