L'Univers a-t-il une forme ? En s'intéressant au contenu visible de l'univers, aux planètes, aux étoiles et aux galaxies, on oublie parfois le contenant invisible, l'espace lui même. Celui-ci est-il un simple réceptacle passif ? A-t-il une forme, une structure ? Est-il fini ou infini ? Est-il courbe, plat, lisse ou grumeleux ?Une présentation des différents modèles cosmologiques. Jean-Pierre Luminet présente les grandes lignes des démarches cosmologiques actuelles et des formes possibles de l'univers.

Jean Pierre Luminet nous invite à un voyage fascinant qui, de la Grèce antique à nos jours, explore les métamorphoses de l'infini. De manière toujours accessible, il aborde l'infini de l'espace avec la cosmologie, celui des nombres avec les mathématiques et les mystères de l'infiniment petit dans la matière avec la physique quantique.

Un Univers en expansion - La cosmologie est l'étude de l'Univers dans son ensemble. En expansion depuis 15 milliards d'années, son histoire est jalonnée d'événements cosmiques : fabrication de la matière, génération du rayonnement cosmologique, apparition des galaxies... La cosmologie est aujourd'hui devenue une science, relativiste depuis le début du XX° siècle.Une histoire de nos nos connaissances sur l'Univers. Marc Lachièze-Rey retrace ici les grandes lignes de l'évolution des idées et des principes qui fondent nos connaissances sur l'Univers.

We are living in a golden age in astronomy and in the search for life the universe. Over the last few decades, space exploration has shown that not only are there habitable environments within our solar system, but there are millions of exoplanets within our galaxy that could support life. We are on the cusp of breakthroughs that will revolutionize our understanding of our place in the cosmos in. In The Secret Life of the Universe, astrobiologist and the director of the Carl Sagan Center at the SETI Institute Nathalie A. Cabrol takes us to the frontiers of the search for life.

Edwin Powell Hubble (November 20, 1889 - September 28, 1953), born in Marshfield, MO, was an American astronomer who played a crucial role in establishing the fields of extragalactic astronomy and observational cosmology. Hubble proved that many objects previously thought to be clouds of dust and gas and classified as "nebulae" were actually galaxies beyond the Milky Way. Hubble's name is most widely recognized for the Hubble Space Telescope, which was named in his honor. The following is a 1945 recording of Hubble's lecture at the New York Philharmonic.

As founding director of Cornell University's Carl Sagan Institute, astrophysicist Lisa Kaltenegger built a team of tenacious scientists from many disciplines to create a uniquely specialized toolkit to find life on faraway worlds. In Alien Earths, she demonstrates how we can use our homeworld as a Rosetta Stone, creatively analyzing Earth's history and its astonishing biosphere to inform this search. With infectious enthusiasm, she takes us on an eye-opening journey to the most unusual exoplanets that have shaken our worldview.

For Irwin Shapiro, science starts with questions. This book provides a broad and entertaining survey of major scientific discoveries that have changed our views of nature and, in turn, spawned further questions. Shapiro, an award-winning scientist and beloved teacher, separates his inquiry into three parts: looking up at the universe; looking down at the earth and its fossils; and looking in at the story of life. His framework encourages listeners to view science as a detective story—to observe and question nature and natural phenomena, and to base all conclusions on scientific evidence.

The violent birth of the universe was only the first bang of a very bumpy ride. This unfathomably cacophonous beginning has spawned blasts, implosions, cosmic cannibalism, collisions, and countless other fleeting energetic events punctuating the cosmos. Although often brief, these transient phenomena pack a powerful punch. Astronomer and science writer C. Renee James introduces us to her colleagues around the world, who are using pioneering research techniques to explore everything from the very first explosions in the universe to the dark energy that could destroy it all.

Spectroscopy, the study of the interaction between matter and electromagnetic radiation, may sound complex and esoteric, but at its heart lies a simple and profound idea: the colors of light can reveal the secrets of the universe. From the examination of distant stars to the analysis of molecules in a laboratory, spectroscopy is the key that unlocks the hidden stories encoded in light.

In the vast expanse of the cosmos, where stars twinkle in the night sky and galaxies swirl in the abyss, a remarkable dance of light and matter unfolds—a dance that has captivated the human imagination for centuries. This dance, illuminated by the science of spectroscopy, is what this book seeks to explore and explain. Spectroscopy, the study of the interaction between matter and electromagnetic radiation, may sound complex and esoteric, but at its heart lies a simple and profound idea: The colors of light can reveal the secrets of the universe.

In this audiobook, astrophysicist Janna Levin blends memoir and visionary science to provide a groundbreaking personal account of her life and ideas.

Humanity has long looked to the sky and marveled at the world around us. We've wondered why the world is the way it is and whether it has to be that way. And we dream of a time when we have developed a theory of everything—a theory that answers all questions. Einstein's Unfinished Dream explores the cutting-edge research of modern particle physicists that pushes us slowly towards a theory of everything....

Em 2016 Stephen Hawking participou da série de palestras BBC Reith Lectures, promovida pela rede de televisão britânica BBC e transmitida pela rádio BBC 4. A cada ano uma figura proeminente em sua área é convidada a discorrer sobre temas relevantes. Naqueles meses de janeiro e fevereiro, Hawking falou sobre um assunto que há décadas ocupa lugar de destaque em suas pesquisas: os buracos negros.

Uma das mentes mais geniais do mundo moderno, Stephen Hawking guia o leitor na busca por respostas a algumas das maiores dúvidas da humanidade: Qual a origem do universo? Ele é infinito? E o tempo? Sempre existiu, ou houve um começo e haverá um fim? Existem outras dimensões além das três espaciais? E o que vai acontecer quando tudo terminar? Com ilustrações criativas e texto lúcido e bem-humorado, Hawking desvenda desde os mistérios da física de partículas até a dinâmica que movimenta centenas de milhões de galáxias por todo o universo.

Desde Einstein, o mundo não via um cientista tão reverenciado quanto Stephen Hawking. Com seu trabalho revolucionário em física e cosmologia, ele encantou milhões de leitores com a origem do universo e a natureza dos buracos negros, além de inspirar todos pela coragem e determinação que mostrou em sua luta contra a doença do neurônio motor. Agora, nesta reunião póstuma de seus trabalhos, podemos conhecer seus pensamentos a respeito das grandes questões que povoam nossas mentes desde os primórdios e daquelas mais prementes na atualidade.

Após o enorme sucesso de Uma breve história do tempo, a Intrínseca traz a luxuosa reedição de O universo numa casca de noz, na qual Stephen Hawking se vale de ilustrações, fotos e esquemas detalhados para mostrar grandes descobertas no campo da física teórica. Tudo isso, é claro, com sua conhecida clareza, elucidando temas complexos por meio de conceitos e ideias do dia a dia, como a inflação, as cartas de baralho e as linhas ferroviárias, e permeado com seu peculiar senso de humor.

Everywhere light goes, It has found that darkness is already there. Darkness is the natural state of the universe. For a star to be born, it takes an astounding number of possibilities to become a reality. From this unlikely alignment, we now have trillions of stars!
