Download E-books Universo: la historia más grande jamás contada PDF

By Gerardo Herrera Corral

Este libro es l. a. historia common de todas las cosas: las estrellas, los angeles gravedad, los inmensos átomos, los angeles luz, el tiempo, el omnipresente Higgs y l. a. minuciosa variedad de l. a. vida.

Gerardo Herrera Corral, quien desde 1994 colabora en el experimento ALICE, del Centro Europeo de Investigaciones Nucleares, cuyo objetivo es recrear l. a. materia que surgió instantes después del large Bang, nos propone un viaje en reversa, un camino de causas y efectos que se detiene en momentos importantes del desarrollo cósmico, y avanza hacia el pasado, buscando el germen de cada estación en l. a. siguiente.

Así, iremos de los angeles conciencia a l. a. vida; de ahí al carbono y su generosa geometría; luego al corazón de las estrellas, que deben morir para que lo demás exista; después visitaremos el plasma primordial del que surgieron los átomos ligeros y sus componentes elementales, y, antes de nuestra última parada -la Gran Explosión-, nos detendremos en l. a. inflación cósmica, el momento decisivo entre el ser y los angeles nada.
