La realtà non è come ci appare: La struttura elementare delle cose

Posted on by

Tempo, spazio e materia appaiono generati da un pullulare di eventi quantistici elementari Comprendere questa tessitura profonda della realt l obiettivo della ricerca in gravit quantistica, la sfida della scienza contemporanea dove tutto il nostro sapere sulla natura viene rimesso in questione Carlo Rovelli, uno dei principali protagonisti di questa avventura, conduce il lettore al cuore dell indagine in modo semplice e avvincente Racconta come sia cambiata la nostra immagine del mondo dall Antichit alle scoperte pi recenti l evaporazione dei buchi neri, l Universo prima del big bang, la struttura granulare dello spazio, il ruolo dell informazione e l assenza del tempo in fisica fondamentale L autore disegna un vasto affresco della visione fisica del mondo, chiarisce il contenuto di teorie come la relativit generale e la meccanica quantistica, ci porta al bordo del sapere attuale e offre una versione originale e articolata delle principali questioni oggi aperte Soprattutto, comunica il fascino di questa ricerca, la passione che la anima e la bellezza della nuova prospettiva sul mondo che la scienza svela ai nostri occhi.

coherent explanation of the origin and fate of the universe how it began, how it works, how it evolves Quantum Gravity also has a pretty fair shot to reconcile the apparent paradoxes and contradictions involved in and between the theories of General Relativity and Quantum Mechanics Most recent scientific observations favour it over alternative theories as the way forward for Physics

of gravity with quantum mechanics, but rather extends quantum mechanics as a granular geometric equation into the macro realm of what we understand as special relativity.In other words, Reality is
