El destino de la nave es un planeta situado a unos treinta a\u00f1os luz de distancia. Recoge hidr\u00f3geno a medida que vuela a trav\u00e9s del espacio y lo quema en una reacci\u00f3n de fusi\u00f3n que impulsar\u00e1 la nave a una velocidad cercana a la de la luz. A bordo, el tiempo subjetivo transcurre m\u00e1s lentamente (como Einstein predijo que suceder\u00eda), de modo que el viaje de varias d\u00e9cadas tendr\u00eda, para los viajeros, una duraci\u00f3n de unos pocos a\u00f1os. En las matem\u00e1ticas de la relatividad hay un factor conocido como tau. Cuanto m\u00e1s se aproxima tau a cero, momento en que la velocidad de la nave tendr\u00eda que igualar te\u00f3ricamente a la de la luz, tanto m\u00e1s grande se hace la nave y tanto m\u00e1s se alarga el tiempo subjetivo en relaci\u00f3n con el resto del universo. A los nueve a\u00f1os luz de la partida de la Tierra, ocurre un accidente: la Leonora Christine choca con una nube de polvo interestelar. Excepto alg\u00fan mal golpe, nada parece haber afectado el vuelo, puesto que la aceleraci\u00f3n contin\u00faa acerc\u00e1ndose a la velocidad de la luz. Sin embargo, poco despu\u00e9s, los tripulantes descubren que el sistema de desaceleraci\u00f3n se ha estropeado y no pueden detener la nave, que sigue ganando velocidad a medida que el factor tau se acerca inexorablemente a cero. As\u00ed, en un per\u00edodo (subjetivo) breve, la nave atraviesa galaxias enteras en un abrir y cerrar de ojos, en el universo exterior transcurren millones de a\u00f1os mientras la nave se hace cada vez m\u00e1s grande, devorando la materia interestelar a un ritmo colosal. Las consecuencias, tanto para la tripulaci\u00f3n como para la trama de la realidad, est\u00e1n ingeniosamente elaboradas.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Poul Anderson<\/p>\n","protected":false},"featured_media":47006,"comment_status":"open","ping_status":"closed","template":"","meta":{"site-sidebar-layout":"default","site-content-layout":"","ast-site-content-layout":"default","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","ast-disable-related-posts":"","theme-transparent-header-meta":"","adv-header-id-meta":"","stick-header-meta":"","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"default","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}}},"product_brand":[23],"product_cat":[5808,5807,5806,6012],"product_tag":[5852],"class_list":["post-9749","product","type-product","status-publish","has-post-thumbnail","product_brand-epub-paradise","product_cat-ebooks","product_cat-epub","product_cat-espanol","product_cat-poul-anderson","product_tag-ciencia-ficcion","desktop-align-center","tablet-align-left","mobile-align-center","first","instock","taxable","shipping-taxable","purchasable","product-type-variable"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.7 -
