In the final book of his astonishing career, Carl Sagan brilliantly examines the burning questions of our lives, our world, and the universe around us. These luminous, entertaining essays travel both the vastness of the cosmos and the intimacy of the human mind, posing such fascinating questions as how did the universe originate and how will it end, and how can we meld science and compassion to meet the challenges of the coming century?

Big History, the field that studies the entire known past of our universe to give context to human existence, has so far been the domain of historians. Geologist Walter Alvarez - best known for his Impact Theory explaining dinosaur extinction - makes a compelling case for a new, science-first approach to Big History.

In this grand poetic vision of the universe, Lawrence Krauss tells the dramatic story of the discovery of the hidden world that underlies reality - and our place within it. Reality is not what you think or sense - it’s weird, wild, and counterintuitive, and its inner workings seem at least as implausible as the idea that something can come from nothing. With his trademark wit and accessible style, Krauss leads us to realms so small that they are invisible to microscopes, to the birth and rebirth of light, and into the natural forces that govern our existence.

Evolution and creation are in a spiritual battle. Evolution scientists ignore, dismiss, and unequivocally reject creation out of hand - "It is not science or fact as evolution is," they say. However, Nullifying God shows that random Darwinian evolution does not have the direct evidence required to support the claim. Not only that, but it provides contrary evidence that evolution is biologically impossible.

Does time exist? What is infinity? Why do mirrors reverse left and right but not up and down? In this scintillating collection, Holt explores the human mind, the cosmos, and the thinkers who’ve tried to encompass the latter with the former. With his trademark clarity and humor, Holt probes the mysteries of quantum mechanics, the quest for the foundations of mathematics, and the nature of logic and truth. Along the way, he offers intimate biographical sketches of celebrated and neglected thinkers, from the physicist Emmy Noether to the computing pioneer Alan Turing and the discoverer of fractals, Benoit Mandelbrot.

You are reading the word now right now. But what does that mean? What makes the ephemeral moment "now" so special? Its enigmatic character has bedeviled philosophers, priests, and modern-day physicists from Augustine to Einstein and beyond. Einstein showed that the flow of time is affected by both velocity and gravity, yet he despaired at his failure to explain the meaning of now. Equally puzzling: Why does time flow? Some physicists have given up trying to understand and call the flow of time an illusion.

Het laatste boek van professor Stephen Hawking. Hoe is alles begonnen? Is er intelligent leven elders in het heelal? Kunnen we de toekomst voorspellen? Bestaat er een God? Wat zit er in een zwart gat? Zijn tijdreizen mogelijk? Zullen we overleven op aarde? Moeten we de ruimte koloniseren? Zal kunstmatige intelligentie slimmer worden dan wij? Hoe geven wij de toekomst vorm? De wereldberoemde wetenschapper en bestsellerauteur Stephen Hawking laat ons zijn laatste ideeën over de grootste vragen van het universum na in dit briljante postuum uitgegeven werk.

Teletransporte, máquinas del tiempo, campos de fuerza y naves intergalácticas: ¿materia de ciencia ficción o tecnologías potencialmente disponibles en el futuro? Inspirado por los mundos fantásticos de H.G. Wells, Star Trek o La guerra de las galaxias, el prestigioso físico teórico y divulgador Michio Kaku lanza una mirada inteligente, seria y a menudo sorprendente a lo que nuestra actual comprensión de las leyes del universo nos permite vislumbrar en el futuro.

>Bodo Zeidler setzt für solche Gedankengänge die Romanfigur "Matthew Widget" in Szene, einen skurrilen Menschen, der im Taumel der Liebe zu besonderen Erkenntnissen gelangt, die entweder unter ferner liefen abzustempeln sind, oder doch die Gelehrten zu neuer Inspiration verleiten mögen. In seinem Hörbuch "Das kleinste Teilchen ist ein Universum", beschaut sich der Autor Bodo Zeidler Weltbilder "Raum und Zeit" und lässt die Romanfigur durch eine gefühlvolle Story laufen, in der viele Fragen beantwortet, oder auch als entscheidende Fragen formuliert werden.

Quanto è grande l'universo? C'è stato un inizio e ci sarà una fine? Come si è fatta strada l'ipotesi del Big Bang? Come si fa a scoprire il passato dell'universo e a prevederne l'evoluzione futura? Domande antiche e in parte ancora irrisolte. Nel volume i passi più importanti del lungo cammino scientifico dall'età moderna fino alle scoperte più recenti, riguardanti la gerarchia di strutture cosmiche, l'espansione dell'universo, lo stato iniziale ultracaldo e ultradenso, che oggi i cosmologi possono osservare direttamente grazie a sofisticati telescopi e strumenti spaziali.

Quando e dove è iniziata la vita? E a cosa somigliavano le prime forme di vita? Interrogativi che l'uomo si pone da sempre, per i quali, pur in mancanza di risposte definitive, si possono avanzare alcune ipotesi. Come quella che colloca l'origine della vita intorno a 3,8 miliardi di anni fa, in un contesto riconducibile a uno di questi ambienti: brodo primordiale, campi geotermali, siti di impatto meteoritico. Certo è che le tessere del più grande e affascinante dei puzzle restano RNA, amminoacidi, protogeni, protocellule.

Keine Kultur kann existieren ohne eine Erzählung von den Ursprüngen. Der italienische Teilchenphysiker und Bestsellerautor Guido Tonelli erzählt in "Genesis" die große Geschichte von der Entstehung unseres Universums, angefangen vom Big Bang und den allerersten Augenblicken danach bis zu unserem Sonnensystem. Sein Buch ist der meisterhafte Versuch, aus dem Wissen der heutigen Astrophysik heraus eine Erzählung von den Ursprüngen zu entwickeln, die nie die Grenzen der Wissenschaft verlässt, sich aber an den großen Mythen messen lassen kann.

The galaxy, the multiverse, and the history of astronomy are explored in this engaging compilation of cosmological "tales" by multiple award-winning science writer Marcia Bartusiak. In 32 concise and engrossing essays, the author provides a deeper understanding of the nature of the universe and those who strive to uncover its mysteries. Bartusiak shares the back stories for many momentous astronomical discoveries, including the contributions of such pioneers as Beatrice Tinsley and her groundbreaking research in galactic evolution.

Scientists in the past few decades have made crucial discoveries about how our cosmos evolved over the past 13.8 billion years. But there remains a critical gap in our knowledge: We still know very little about what happened in the first seconds after the Big Bang. At the Edge of Time focuses on what we have recently learned and are still striving to understand about this most essential and mysterious period of time at the beginning of cosmic history.

This new and long-awaited sequel to Carl Sagan's international best seller continues the electrifying journey through space and time, linking worlds within and worlds billions of miles away and envisioning a future of science tempered with wisdom. Based on National Geographic's internationally-renowned television series, this groundbreaking and visually stunning book explores how science and civilization grew up together.

How to Love the Universe is a new kind of science writing by an author truly enamored of the world around him. In 10 short chapters of lyrical prose - each one an ode to a breathtaking realm of discovery - Stefan Klein uses everyday objects and events as a springboard to meditate on the beauty of the underlying science.

In Signposts to God, particle physicist Peter Bussey introduces listeners to the mysteries of modern physics and astronomy. Authored in clear, accessible prose, Bussey provides a primer on topics such as the laws of nature, quantum physics, fine-tuning, and current cosmological models. Bussey argues that, far from ruling out a divine creator, modern physics and astronomy present us with compelling signposts to God. The more we know about the cosmos and our presence in it, the more plausible belief in God becomes.

We know the universe had a beginning. With the Big Bang, it expanded from a state of unimaginable density to an all-encompassing cosmic fireball to a simmering fluid of matter and energy, laying down the seeds for everything from black holes to one rocky planet orbiting a star near the edge of a spiral galaxy that happened to develop life as we know it. But what happens to the universe at the end of the story? And what does it mean for us now?
