El nacimiento del tiempo / the Birth of Time

El Nacimiento Del Tiempo / The Birth Of Time


He aqui la historia de uno de los grandes enigmas cientificos de nuestro tiempo y de como al fin ha sido desvelado. Loa astronomos, geologos y evolucionistas del siglo XIX fueron los primeros en sugerir que, contrariamente a lo que afirma el relato biblico, la Tierra y el Sol tenian -al menos- millones de anos. Ya a principios del siglo XX, muchos profesionales del sector asumian tacitamente que el universo era muy, muy viejo. Y, llegados los anos veinte, el descubrimiento del universo en expansion por parte de Edward Hubble, junto con la teoria de la relatividad de Einstein, apuntaron hacia un posible principio de ese mismo universo: la gran explosion primigenia o big bang. Luego se sucedieron las investigaciones y las teorias hasta que, en los anos noventa, en la Universidad de Sussex, John Gribbin y sus colegas empezaron a desarrollar una nueva tecnica para cuantifcar, clara y exactamente, la teoria de Hubble. Y a mediados de I 997 habian conseguido ya la clave para establecer finalmente que el universo es mas viejo que las estrellas que contiene. Pues bien, este libro es el resultado de esas indagaciones, un intrigante relato lleno de pistas falsas, callejones sin salida y tanteos en penumbra en busca de la verdad. La obra de un cientifico que, como investigador y astronomo, intervino directamente en el gran descubrimiento final.
