Jonas Enander

From the 18th century vicar who was the first to look up at the night's sky and suggest there was something very dark and extraordinarily heavy that was moving the stars, to the first actual photograph of a black hole, 250 years later, Jonas Enander has travelled the world, visited telescopes and observatories, interviewed world-leading space researchers, and delved deep into the archives to investigate how our relationship with black holes has changed over time. Throughout this journey, Enander explores how our desire to answer the question of the origin of the universe inadvertently led to the invention of WiFi and the calibration of GPS; how our looking outward gave us critical evidence of our impact on climate change that could be the key to the future of all humanity and how colonialism sparked the race for discovery, affecting those most vulnerable, creating a ripple effect being felt to this day. Discover how black holes work, where they come from, and what role they play in the universe. How is it even possible to know that we are on a 230 million year journey around the Milky Way with an enormous black hole at its centre? How is it possible to determine that this black hole has a mass equivalent to four million suns? What happens when black holes collide? Are we living in a black hole? And how do we even know any of this? Based on interviews with over 20 leading black hole researchers, including several Nobel Laureates, Facing Infinity deciphers the most mind-bending science whilst retaining a sense of wonder, in an approachable and spellbinding journey into the universe's greatest mysteries.

'Combines science with journalism to weave a captivating account of the most extraordinary objects in the universe: black holes. A superior account.' Marcus Chown 'Facing Infinity is an especially attractive introduction to a wonderfully attractive subject.' Frank Wilczek Black holes aren't just cosmic mysteries - they're surprisingly essential to life on Earth. From GPS navigation to understanding climate change, these enigmatic objects shape our daily existence in ways you'd never imagine. They helped create the atoms in your body, mixed the chemical ingredients for life throughout the universe, and now help us measure our planet's changing surface with millimetre precision. In Facing Infinity, astrophysicist Jonas Enander takes us on an extraordinary journey from eighteenth-century Britain to cutting-edge observatories around the world, revealing how the universe's darkest phenomena illuminate both our origins and future.

Experimentet sprider sig. Åtminstone sedan 1600-talet har det varit en bärande del av vetenskaplig metodik och undervisning, men nu hörs ordet långt bort från klassrum och labbsalar. Att gifta sig med en främling på tv eller öppna upp sitt förhållande är också ett experiment. I matstäder som Köpenhamn dyker det upp pasta labs i gathörnen och på nyheterna omtalas långtgående lagförslag som experiment med människors trygghet och mellanstadieelevers liv. Vad betyder begreppet experiment idag? Ses det som bra eller dåligt att experimentera? Det här numret är en essäistisk sammanställning av experiment som nu återstår att pröva.

Svarta hål: ett av universums största mysterier. En sorts inre kollaps, ett ställe dit materia färdas för att dö, närmast omöjliga att studera. Men ju mer vi lär oss om vad svarta hål egentligen är, desto mer lär vi oss även om vårt eget ursprung samt vår plats på jorden och i universum. Jonas Enander har rest världen över, besökt teleskop och observatorier, intervjuat världsledande rymdforskare och grävt djupt i arkiven för att undersöka hur vår relation till svarta hål har förändrats genom åren. Mörkret och människan är ett slags reseberättelse i tid och rum som lika mycket handlar om forskningen som om människorna bakom den, från Tycho Brahe till dagens Nobelpristagare. Det blir en trollbindande och närmast existentiell betraktelse över ljus och mörker, skapelse och förstörelse, liv och död.
