What would happen if you fell into a Black Hole?Black holes are found throughout the universe. They can be microscopic. They can be billions of times larger than our Sun. They are dark on the outside but not on the inside. Anything that enters them can never escape, and yet they contain nothing at all.In Black Hole Survival Guide physicist and novelist Janna Levin takes you on a journey into a black hole, explaining what would happen to you and why. In the process you'll come to see how their mysteries contain answers to some of the most profound questions ever asked about the nature of our universe.'Astrophysics at its sexiest...hugely enjoyable' Sunday Times

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. Cinco décadas después de soñar el experimento, el equipo se afana por interceptar un sonido con dos colosales máquinas, con la esperanza de tener éxito a tiempo para el centenario de la idea más radical de Einstein.

Mixing memoir and visionary science, a leading astrophysicist’s groundbreaking personal account of her life and ideasIs the universe infinite or just really big? With this question, cosmologist Janna Levin announces the central theme of this book, which established her as one of the most direct, unorthodox, and creative voices in contemporary science. As Levin sets out to determine how big “really big” may be, she offers a rare intimate look at the daily life of an innovative physicist, complete with jet lag and the tensions between personal relationships and the extreme demands of scientific exploration. Nimbly explaining geometry, topology, chaos, and string theory, Levin shows how the pattern of hot and cold spots left over from the big bang may one day reveal the size of the cosmos. The result is a thrilling story of cosmology by one of its leading thinkers.

The full inside story of the detection of gravitational waves at LIGO, one of the most ambitious feats in scientific history*Selected as a Book of the Year 2016 in the Sunday Times*'This is empirical poetry. A fascinating tale of human curiosity beautifully told, and with black holes and lasers too' Robin InceIn 1916 Albert Einstein predicted the existence of gravitational waves: miniscule ripples in the very fabric of spacetime generated by unfathomably powerful events. If such vibrations could somehow be recorded, we could observe our universe for the first time through sound: the hissing of the Big Bang, the low tones of merging galaxies, the drumbeat of two black holes collapsing into one… In 2016 a team of hundreds of scientists at work on a billion-dollar experiment made history when they announced the first ever detection of a gravitational wave, confirming Einstein’s prediction a century ago. Based on complete access to LIGO (Laser Interferometer Gravitational-Wave Observatory) and the scientists who created it, Black Hole Blues offers a first-hand account of this astonishing achievement: an intimate story of cutting-edge science at its most awe-inspiring and ambitious.
