Did an enormous collision in the Asteroid Belt, orbiting the sun between Mars and Jupiter, bombard Earth with meteorites 470 million years ago? Astonishing new research suggests it did, and a revolutionary theory is emerging that this bombardment resulted in the single greatest increase in biological diversity on the planet since the origin of life. Introducing these discoveries to the general public for the first time, Ted Nield challenges the view that meteorites are bad news. Tracing the history of meteorites from the first recorded strike to the videos made routinely today, he reveals the fascinating ways in which meteorites have transformed from omens of doom to a stepping stone to Mars in twenty-first-century space exploration. The Falling Sky will shatter everything you thought you knew about one of the most terrifying forces in the universe.

Every rock is a tangible trace of the earth’s past. The Story of the Earth in 25 Rocks tells the fascinating stories behind the discoveries that shook the foundations of geology. In twenty-five chapters—each about a particular rock, outcrop, or geologic phenomenon—Donald R. Prothero recounts the scientific detective work that shaped our understanding of geology, from the unearthing of exemplary specimens to tectonic shifts in how we view the inner workings of our planet. Prothero follows in the footsteps of the scientists who asked—and answered—geology’s biggest questions: How do we know how old the earth is? What happened to the supercontinent Pangea? How did ocean rocks end up at the top of Mount Everest? What can we learn about our planet from meteorites and moon rocks? He answers these questions through expertly chosen case studies, such as Pliny the Younger’s firsthand account of the eruption of Vesuvius; the granite outcrops that led a Scottish scientist to theorize that the landscapes he witnessed were far older than Noah’s Flood; the salt and gypsum deposits under the Mediterranean Sea that indicate that it was once a desert; and how trying to date the age of meteorites revealed the dangers of lead poisoning. Each of these breakthroughs filled in a piece of the greater puzzle that is the earth, with scientific discoveries dovetailing with each other to offer an increasingly coherent image of the geologic past. Summarizing a wealth of information in an entertaining, approachable style, The Story of the Earth in 25 Rocks is essential reading for the armchair geologist, the rock hound, and all who are curious about the earth beneath their feet.

Astonishing new research suggests that 470 million years ago, a stupendous collision in the Asteroid Belt (whose debris is still falling today) bombarded the Earth with meteorites of all sizes. A revolutionary idea is emerging that the resulting ecological disturbance may have been responsible for the single greatest increase in biological diversity since the origin of complex life – the hitherto unexplained Great Ordovician Biodiversity Event. Introducing these fresh discoveries to a wider public for the first time, Ted Nield challenges the orthodox view that meteorite strikes are always bad news for life on Earth. He argues that one of the most widely known scientific theories – that dinosaurs were wiped out by a strike 65 million years ago – isn’t the whole picture, and that the causes of the end-Cretaceous mass extinction (of which the dinosaurs’ demise was a part) were much more varied and complex. Meteorites have been the stuff of legend throughout human history, interpreted as omens of doom or objects of power. But only in the eighteenth century, when the study of falling space debris became a science, were meteorites used to unlock the mysteries of our universe. Incoming! traces the history of meteorites from the first recorded strike to the video recordings made routinely today, showing how our interpretations have varied according to the age in which they fell, and how meteorite impacts were given fresh urgency with the advent of the atom bomb. Introducing a wealth of fascinating characters alongside extraordinary new research, Ted Nield has written the perfect introduction to the science and history of 'the falling sky'.

Die Natur der Dunklen Materie gehört zu den spannendsten Fragen der Kosmologie. Die Bestseller-Autorin und Harvard-Professorin Lisa Randall nimmt uns in ihrem neuen Buch ›Dunkle Materie und Dinosaurier. Die erstaunlichen Zusammenhänge des Universums‹ mit auf eine Reise in die Welt der Physik und hilft uns zu verstehen, welche Rolle die Dunkle Materie bei der Entstehung unserer Galaxie, unseres Sonnensystems und sogar des Lebens selbst gespielt hat. Eindrucksvoll zeigt sie, wie die Wissenschaft neue Konzepte und Erklärungen für dieses weithin unbekannte Phänomen entwickelt und verwebt geschickt die Geschichte des Kosmos mit unserer eigenen. Ein Buch, das ein völlig neues Licht auf die tiefen Verbindungen wirft, die unsere Welt so maßgeblich mitgeprägt haben, und uns die außerordentliche Schönheit zeigt, die selbst den alltäglichsten Dingen innewohnt.
