Science Cosmology

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.

Led by physicist James Trefil and astrophysicist Shobita Satyapal, this book traverses the incredible history of black holes and introduces contemporary developments and theories on still unanswered questions about the enigmatic objects. From the early work of Albert Einstein and Karl Schwarzschild to an insider look at black hole-galaxy connection research led by co-author Satyapa, the comprehensive book surveys an exciting and evolving branch of space science, with topics that include:

Mit diesem Hörbuch begeben Sie sich auf eine Reise vom Beginn des Universums in die ferne Zukunft: Was ist Zeit? Kann man den Urknall sehen? Wie funktioniert Inflation? Wie entstehen Sterne? Wie untersucht man Exoplaneten? Wie sieht die Zukunft des Universums aus? Kann die Zeit enden? Fünfzehn allgemeinverständliche Beiträge aus Spektrum der Wissenschaft und Sterne und Weltraum bieten dem Leser einen vielfältigen Blick auf unser Universum: der erste Teil der Beiträge beschäftigt sich mit dem frühen Universum, mit Zeit, Urknall, Inflation und Dunkler Materie.

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?

Este audiolibro analiza las probabilidades existentes de vida sin consciencia alguna y el desarrollo de civilizaciones a partir de seres racionales. Para que existan vidas similares a la humana más allá de la Tierra es necesario que estos dos saltos cualitativos que se produjeron en la Tierra tengan lugar también en otro lugar del Universo. Según los conocimientos científicos actuales, lo primero es relativamente probable, no así lo segundo, lo cual no significa que sea imposible.

"La sorpresa viene da lontano. Molto, molto lontano. Dalle sorgenti delle galassie, dalle fucine delle stelle, fonti di un'energia inesausta. Là dove abbiamo cominciato a guardare e ormai non possiamo più smettere." La materia e l'energia oscura sono il grande rompicapo della fisica del XXI secolo. E finché rimarranno un enigma, dell'universo conosceremo solo una piccolissima porzione e nulla sapremo della sua origine e del suo inevitabile destino.

L'universo racchiude numerosi segreti e potrebbe perfino nascondere dimensioni inimmaginabili: universi paralleli, geometrie curve e inghiottitoi tridimensionali sono alcuni degli straordinari concetti che di recente sono divenuti protagonisti della ricerca scientifica. Oggi, delle leggi del cosmo capiamo molto più di qualche anno fa, eppure abbiamo molte meno certezze sulla sua vera natura. Nel suo percorso di ricerca nel campo della cosmologia e della fisica, Lisa Randall ha dovuto abbattere alcuni paletti della scienza ufficiale.

Wir wissen, dass das Universum vor vielen Milliarden Jahren in einem gewaltigen Feuerball entstand - dem Urknall. Aber wie wird die Geschichte unseres Universums enden? Wird es in unvorstellbarer Hitze verglühen - oder in eisiger Starre vergehen? Wird es zu einem Klumpen unendlicher Dichte kollabieren, und wird das Ende wirklich das Ende sein - oder entsteht das Universum danach von Neuem? Die renommierte Astrophysikerin Katie Mack nimmt uns mit auf eine faszinierende Reise zu den Grenzen von Raum und Zeit und zeigt auf unterhaltsame Weise, was die Wissenschaft über das Ende des Kosmos weiß.

Wenn die Galaxien-Forscherin Ruth Grützbauch nicht mit ihrem Pop-up-Planetarium, das in ein Lastenrad passt, durch die Lande fährt, bringt sie den Menschen in ihrem erfolgreichen Podcast die unendlichen Weiten des Weltraums näher. Kenntnisreich, mitreißend und charmant erzählt sie in "Per Lastenrad durch die Galaxis" die Geschichte des Kosmos als eine Geschichte der Galaxien. Ihr Hörbuch ist originell illustrierter Roadtrip zum Anfang des Universums und Lob der Astronomie - und ihrer gigantischen Teleskope, mit deren Hilfe wir das Unsichtbare zu sehen vermögen - in einem.

Astronomers have determined that our universe is 13.7 billion years old. How exactly did they come to this precise conclusion? How Old Is the Universe? tells the incredible story of how astronomers solved one of the most compelling mysteries in science and, along the way, introduces listeners to fundamental concepts and cutting-edge advances in modern astronomy.

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....

In this vibrant, eye-opening tour of milestones in the history of our universe, Chris Impey guides us through space and time, leading us from the familiar sights of the night sky to the dazzlingly strange aftermath of the Big Bang. What if we could look into space and see not only our place in the universe but also how we came to be here? As it happens, we can. Because it takes time for light to travel, we see more and more distant regions of the universe as they were in the successively greater past.

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.

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.

Sometimes our understanding of our universe is given a huge boost by one insightful thinker. Such a boost came in the first half of the 20th century, when an obscure Belgian priest put his mind to deciphering the nature of the cosmos. The Day Without Yesterday covers the modern history of an evolving universe, and how Georges Lemaître convinced a generation of thinkers to embrace the notion of cosmic expansion and the theory that this expansion could be traced backward to the cosmic origins, a starting point for space and time that Lemaître called "the day without yesterday".

"The Beginner's Guide to Parallel Realities" transforms mind-bending concepts into accessible insights that will forever change how you view reality. Using clear examples and engaging thought experiments, this guide breaks down complex theories about the multiverse, time travel, and alternate dimensions into digestible pieces that anyone can understand.
