Acostumbrados como estamos a pensar que el Universo es único, centramos nuestros esfuerzos en averiguar qué contiene y cuál es su estructura. En El libro de los universos, el distinguido físico teórico, astrofísico cosmólogo y divulgador John Barrow ha adoptado otra perspectiva. Tomando como base, la cosmología relativista que produjo Albert Einstein en 1916, Barrow indaga en un amplio conjunto de soluciones exactas de las ecuaciones básicas de esa teoría, soluciones que representan muy diversos tipos de universos posibles. Algunos se expanden y otros se contraen. Los hay también que son perfectamente lisos, mientras que otros están llenos de bultos y no faltan los que huyen a toda velocidad hacia un futuro de expansión sin límites. Algunos permiten viajar en el tiempo hacia el pasado y en sólo unos pocos puede surgir vida. El lector se encontrará, asimismo, con universos en los que las leyes de la física pueden cambiar con el tiempo y con el lugar, universos con dimensiones ocultas, o universos inflacionarios (que experimentan aceleraciones repentinas). Finalmente, y tras presentarnos los últimos descubrimientos acerca de nuestro propio universo, Barrow nos introduce a una de las ideas más sorprendentes y radicales acerca del universo, la del ?Multiuniverso? - el universo de todos los posibles universos -, que las modernas teorías de la física cada vez se toman más en serio.John Barrow nos muestra en esta obra que, más allá de nuestro universo, existen muchos otros de todo tipo: desde los que se contraen o se expanden sin límite, hasta los que permiten viajar hacia el pasado o reúnen las condiciones para que pueda surgir la vida.
