EN UN SEGON. LES VELOCITATS DE L'UNIVERS
Romero S.
Poden passar tantes coses en un segon! En aquesta fracció de temps, per exemple, l'univers és capaç de crear 4.000 estrelles noves. De vegades, però, passa el contrari: la natura canvia el ritme trepidant per una pacient lentitud, i una llavor pot necessitar anys per convertir-se en un arbre. Aquest llibre és un descobriment fascinant de les diferents velocitats de l'univers.
