Cosa succederebbe se la Terra orbitasse attorno a un buco nero? E se dalla sua superficie sparissero tutti gli oceani? E se venisse colpita da una supertempesta solare? E il Sole, appunto: se un giorno levassimo il naso all'insù senza più vederlo? Se qualcuno volesse improvvidamente tentare di spegnerlo con una gigantesca secchiata d'acqua? (Spoiler: sarebbe una pessima idea.) E la Luna! Cosa accadrebbe se una notte in cielo ne spuntassero due? Raddoppierebbe la poesia o ci ritroveremmo non esattamente nelle condizioni ideali per apprezzare la cosa? Ancora, allargando il raggio dei nostri interrogativi all'universo: quale sarebbe l'effetto se fosse pieno d'aria anziché vuoto? E cosa vedremmo immaginando di poter piazzare uno specchio a dieci anni luce di distanza dalla Terra? Tutti questi sono solo alcuni dei tanti paradossi, ora più inquietanti ora più gustosi, in cui ci imbatteremo nelle pagine di questo libro. A guidarci tra le soluzioni penseranno Filippo Bonaventura, Lorenzo Colombo e Matteo Miluzio - giovani astrofisici già autori su Facebook della seguitissima pagina di divulgazione "Chi ha paura del buio?" - con il loro inconfondibile stile tanto divertente nella forma quanto rigoroso e impeccabile nei contenuti scientifici.
