Un apasionante paseo por la historia del espacio, con una voz ingeniosa y encantadora y muchas referencias a la cultura pop. Smethurst es una de las más conocidas divulga- doras de astrofísica en el Reino Unido, colabora- dora habitual en la BBC y visitará nuestro país para promocionar su exitoso ensayo. Nuestro gran lanzamiento de divulgación del 2024. En la línea del universo en tu mano o gravedad, una nueva voz que dará mucho que hablar. En este preciso momento estás orbitando alrededor de un agujero negro. Rebecca Smethurst, galardonada investigadora de la Universidad de Oxford, arroja luz sobre el fenómeno más misterioso y emocionante de la astrofísica, y desarma los equívocos construidos a su alrededor para contarnos la verdad. Que los agujeros negros no son realmente negros. Que se parecen más a una mullida almohada que a una potente aspiradora. Que orbitamos alrededor del agujero negro supermasivo denominado La Vía Láctea. Un ensayo cautivador que nos lleva desde el colapso de las primeras estrellas hasta los últimos hallazgos de la astronomía, y que da respuesta a las preguntas más profundas sobre el universo y sobre nuestro lugar en él.

In A Brief History of Black Holes, award-winning University of Oxford researcher Dr Becky Smethurst charts five hundred years of scientific breakthroughs in astronomy and astrophysics. Right now, you are orbiting a black hole. The Earth orbits the Sun, and the Sun orbits the centre of the Milky Way: a supermassive black hole, the strangest and most misunderstood phenomenon in the galaxy. In this cosmic tale of discovery, Dr Becky Smethurst takes us from the earliest observations of the universe and the collapse of massive stars, to the iconic first photographs of a black hole and her own published findings. She explains why black holes aren’t really ‘black’, that you never ever want to be ‘spaghettified’, how black holes are more like sofa cushions than hoovers and why, beyond the event horizon, the future is a direction in space rather than in time. Told with humour and wisdom, this captivating book describes the secrets behind the most profound questions about our universe – all hidden inside black holes. 'A jaunt through space history . . . with charming wit and many pop-culture references' – BBC Sky At Night Magazine

Un viaje extraordinario a los límites del tiempo, el espacio y la mente humana. El 10 de abril de 2019 un equipo internacional de astrónomos liderados por el profesor Heino Falcke maravilló al mundo publicando la primera imagen de un agujero negro. Por fin la comunidad científica conseguía la prueba irrefutable de lo que Einstein había predicho en su teoría de la relatividad acerca de estos fenómenos hacía más de cien años. Sin embargo, las implicaciones de este hallazgo van más allá: si bien son objetos relativamente simples de definir, los agujeros negros plantean algunos de los interrogantes más complejos sobre la naturaleza del espacio, del tiempo, y, por último, de nuestra existencia. En este libro, Falcke no solo nos narra la emocionante historia de esta proeza científica, sino que da un paso más intentando responder a las grandes preguntas filosóficas que este hito plantea: ¿existe algo más allá de la nada?, ¿puede la ciencia explicar lo inexplicable?, ¿cuál es el origen de nuestra existencia y qué sentido tiene nuestro paso por el mundo? Para Heino Falcke, la astrofísica y la metafísica, la razón y la fe, no tienen por qué excluirse mutuamente. La luz en la oscuridad es un poderoso alegato a favor de la ciencia que nos habla de lo que sabemos pero también de los misterios que quedan por resolver. ENGLISH DESCRIPTION A fascinating and thought-provoking investigation into the nature of black holes—a blend of the spiritual, the philosophical, and the scientific—from the premier German astrophysicist who made history in 2019, capturing the first one on film. A Light in the Darkness is the story of one of the greatest astrological achievements of all time: the first photographic evidence of black holes in April 2019, and its significance for humanity, told by the scientist who accomplished it. A man of faith ordained in the Protestant tradition, Heino Falcke wrestles with the ways in which black holes force us to confront the boundary where human life ends and the celestial begins. He also ponders why black holes are difficult for most of us to understand—comparing it to our inability to envisage our own inevitable death. Black holes develop in outer space when a massive star dies, and its matter is condensed. That extreme amount of mass contained in a small space generates a gigantic amount of gravitational force, allowing the black hole to suck up everything that comes near, including light. These astronomical wonders are the subject of our greatest scientific and philosophical theorizing—the journey to a black hole would be the journey to the end of time itself. In this way, Falcke regards them as the most exquisite representations of fear, death . . . and, surprisingly, the divine. Empirical and profound, A Light in the Darkness is the first work to examine both the physical nature and spiritual meaning of black holes, those astrophysical mysteries Falcke, calls “the epitome of merciless destruction.”

On December 26, 2015, the Laser Interferometer Gravitational-Wave Observatory (LIGO) detected gravitational waves generated from merging black holes for the first time in human history. Through an engaging, easily accessible approach, the origins, dynamics, and ultimate fate of black holes are thoroughly unraveled so that students without a scientific background can grasp complex physics theories. This book supports the Next Generation Science Standards' emphasis on scientific collection and analysis of data and evidence-based theories by discussing the methods research universities and space agencies use to explore black holes.

Black holes are undoubtedly one of the most fascinating discoveries of modern astronomy, and their description one of the most daring intellectual feats of modern times. They have already become legendary, forming the basis of many myths, fantasies and science fiction movies. Are they really the monsters which devour light and stars; bottomless celestial pits into which all matter is sucked and crushed? Are they an observable reality, or are they just hypothetical objects from the theory of relativity? In answering such questions the author takes us on a fabulous journey through space and time. Dr Jean-Pierre Luminet is an astronomer at Meudon Observatory in France, a specialist on the subject of black holes, and has also acquired a reputation for being a gifted writer and communicator. In this book he makes the subject of black holes accessible to any interested reader, who will need no mathematical background.
