Black holes are the most extraordinary phenomenon in the universe, but they are a riddle that confounds our intuitions. Anything that enters them can never escape and yet they contain nothing at all. They are bigger on the inside than the outside suggests. They are dark on the outside but not on the inside. They invert time into space and space into time.

Janna Levin takes us on an evocative exploration of black holes, provoking us to imagine the visceral experience of a black hole encounter. She reveals the influence of black holes as they populate the universe, sculpt galaxies, and even infuse the whole expanse of reality that we inhabit. Lively, engaging, and utterly unique, Black Hole Survival Guide is not just informative - it is, as well, a wonderful listen from first to last.

Stai viaggiando nel cosmo con la tua astronave. All’improvviso ti trovi di fronte a una totale assenza di luce: un buio su sfondo nero circondato da stelle, una misteriosa oscurità in apparenza priva di massa che ti attrae, per sfuggire alla quale devi aumentare gradualmente la potenza dei retrorazzi. Non devi oltrepassare il punto di non ritorno, quello dopo il quale, per salvarti, dovresti spingere i motori fino a superare i 300 000 chilometri al secondo della velocità della luce.

En 1916, Einstein predijo la existencia de ondas gravitacionales, su máxima prioridad después de proponer su teoría del espacio-tiempo curvo. Un siglo después, estamos grabando los primeros sonidos del espacio, evidencia de la existencia de las ondas causadas por la colisión de dos agujeros negros. Es la banda sonora que acompaña a la película muda de la astronomía. Janna Levin relata la ambición experimental que comenzó como un divertido experimento mental y se convirtió en objeto de obsesión para los arquitectos originales de la idea: Rai Weiss, Kip Thorne y Ron Drever.
