Y a-t-il une vie extraterrestre intelligente<\/strong> dans l'espace ? Une grande question qui alimente les d\u00e9bats scientifiques depuis de nombreuses ann\u00e9es, et qui est source d'inspiration pour de nombreuses \u0153uvres de fiction. Dans l'immense majorit\u00e9 des cas, on imagine les aliens beaucoup plus avanc\u00e9s que nous technologiquement<\/strong>, voyageant \u00e0 bord de vaisseaux futuristes propuls\u00e9s par des moyens dont on ne peut que r\u00eaver sur Terre. Par exemple le fameux moteur \u00e0 distorsion<\/strong> de Star Trek<\/strong>, qui permet de se d\u00e9placer \u00e0 la vitesse de la lumi\u00e8re <\/strong>voire au-del\u00e0.
\n<\/strong><\/p>\n

Mais alors qu'on commence \u00e0 peine \u00e0 d\u00e9montrer que construire un tel engin est th\u00e9oriquement possible<\/a>, des chercheurs pensent qu'ils existent d\u00e9j\u00e0, quelque part au-dessus de nos t\u00eates. Il suffit de savoir quoi regarder pour les rep\u00e9rer. Partant de ce postulat, une \u00e9tude<\/a> s'int\u00e9resse \u00e0 ce qu'il se passerait si un tel moteur venait \u00e0 conna\u00eetre une “d\u00e9faillance de confinement<\/em>“, autrement dit un souci technique qui laisserait une trace d\u00e9tectable dans l'espace<\/strong>.<\/p>\n
