Science Cosmology

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.

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.

Forty-four science articles using the Rational Scientific Method of Inquiry. These subjects are covered in the book Curious Chain of Events, and this is the first in a series of Rational Science books.

The universe should be fun, and you’re about to discover an audiobook that understands that, weaving humor and wit into every minute so that you not only understand what you’re listening to, but enjoy the whole process.

In this special thematic anthology, we traverse the solar system, the galaxies and the multiverse, voyaging across space to explore 25 celestial objects and phenomena. Included are programmes on the universe, the sun, the moon, the stars and the planets - among them our near neighbours, Venus and Mars. Also featured are discussions on comets, asteroids and black holes, as well as eclipses, exoplanets and the mysterious, invisible substance known as 'dark matter'.

In 2000, Martin Bojowald, then a 27-year-old post-doc at Pennsylvania State University, used a relatively new theory called loop quantum gravity - a cunning combination of Einstein’s theory of gravity with quantum mechanics - to create a simple model of the Universe. Loop quantum cosmology was born, and with it, a theory that managed to do something even Einstein’s general theory of relativity had failed to do - illuminate the very birth of the Universe.

We have long fantasized about finding life on planets other than our own. Yet even as we become aware of the vast expanses beyond our solar system, it remains clear that Earth is exceptional. The question is: Why? In Lucky Planet, astrobiologist David Waltham argues that Earth’s climate stability is what makes it uniquely able to support life, and it is nothing short of luck that made such conditions possible. The four-billion-year stretch of good weather that our planet has experienced is statistically so unlikely that chances are slim that we will ever encounter intelligent extraterrestrial others.

An accessible look at the mysteries that lurk at the edge of the known universe and beyond. The observable universe, the part we can see with telescopes, is incredibly vast. Yet recent theories suggest that there is far more to the universe than what our instruments record - in fact, it could be infinite. Colossal flows of galaxies, large empty regions called voids, and other unexplained phenomena offer clues that our own "bubble universe" could be part of a greater realm called the multiverse.

It takes a certain amount of courage to step beyond one's day-to-day experiments and look at the big picture - and the origin of the Moon is a big picture question par excellence. Perhaps it makes sense that William Hartmann, one of the two scientists who unraveled the Moon's biggest mystery, is not only a scientist but also a part-time artist and science fiction writer. It took someone with an artist's eye and a fiction writer's speculative temperament to see the big picture....

Visualize and explore the wonders of our universe. Black holes, dark matter, space-time, gravity, light-speed, orbits, photons, dark energy, solar systems, the big bang, expansion, the shape of the universe, and even the multiverse!

The fascinating science behind the eventual end to everything - from the individual to all existence. Although we may try to keep it tucked at the back of our minds, most of us are aware of our own mortality. But few among us know what science, with the help of insights yielded from groundbreaking new research, has to say about death on a larger scale. Enter astronomer Chris Impey, who chronicles the death of the whole shebang.

Perhaps more than any other scientist of our century, Edward O. Wilson has scrutinized animals in their natural settings, tweezing out the dynamics of their social organization, their relationship with their environments, and their behavior, not only for what it tells us about the animals themselves, but for what it can tell us about human nature and our own behavior. He has brought the fascinating and sometimes surprising results of these studies to general readers through a remarkable collection of books.

An ancient document was found and its basic message is that mankind will be destroyed by an asteroid hitting Earth. To understand and assess the truth of this, Asteroid Impact: Revelation Foretells Our End reviews the purpose of Revelation, who wrote it, and why and how it was written. The book explores the scientific facts upon which the predictions of the Bible are based and analyzes the history of asteroid impacts on Earth in order to assess the accuracy of Biblical predictions.

The Short Story of the Universe is a new introduction to the subject of the universe. Covering 130 key components that make it up - from dwarf galaxies and spiral arms to red giants and the planets of the solar system - and linking these to the universe's structure and the theories that help us understand it, this book simplifies this riveting yet mind-boggling subject, telling the story of how it came into being and how it will eventually be no more.

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! Thankfully stars would progress to give us light, life, and an observable universe. No one knows how many stars exist, but we will tour a handful of the most famous in our known universe. Sit back and enjoy the world of outer space that spreads before you. Each constellation and luminary has a story that you won’t want to miss!

Cosa succederebbe se la Terra orbitasse attorno a un buco nero? E se dalla sua superficie sparissero tutti gli oceani? E se venisse colpita da una supertempesta solare? E il Sole, appunto: se un giorno levassimo il naso all'insù senza più vederlo? Se qualcuno volesse improvvidamente tentare di spegnerlo con una gigantesca secchiata d'acqua? (Spoiler: sarebbe una pessima idea.) E la Luna! Cosa accadrebbe se una notte in cielo ne spuntassero due? Raddoppierebbe la poesia o ci ritroveremmo non esattamente nelle condizioni ideali per apprezzare la cosa?

¿Cuáles son los mayores retos con los que se presenta el planeta, cuáles las mayores amenazas, dónde buscar la solución a los descomunales problemas con los que se enfrenta nuestra generación y las futuras? El origen y evolución del universo, la naturaleza del tiempo, la estructura de la materia, el infinito,las estrellas fugitivas, las ondas gravitacionales…Estos son algunos de los grandes temas que Rafael Bachiller aborda en este libro tanto desde un punto de vista científico como desde una perspectiva filosófica y humanista.

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.

In the early 17th century, Galileo broke free from the hold of ancient Platonic and Aristotelian philosophy. He drastically changed the framework through which we view the natural world when he asserted that we should base our theory of reality on what we can observe rather than pure thought. In the process, he invented what we would come to call science. This set the stage for all the breakthroughs that followed - from Kepler to Newton to Einstein.
