Science Cosmology

No direct explanation is given for the origin and nature of the luminous bodies, the sun, the planets, and the stars. Because the Sumerians regarded the moon-god, who went by the names Sin and Nanna, as the son of the air-god Enlil, it does not seem unreasonable to suggest that they saw the moon as a bright, air-like body fashioned from the atmosphere. As the sun-god Utu and the Venus goddess Inanna are always referred to as children of the moon-god, these luminous bodies were probably imagined as having come from the moon after the latter had been formed from the atmosphere.

Highly esteemed astrophysicist Joseph Silk explores the vast mysteries and speculations of the field of cosmology in a way that balances an accessible style for the general reader and enough technical detail for advanced students and professionals. Indeed, while the physical laws and origins of the universe can be endlessly complex, even Einstein once mused that they could be explained simply enough to be grasped by nonspecialists.

Fra tutte le teorie scientifiche, la relatività è quella che più ci affascina e ci sconcerta. Andando contro la nostra rassicurante percezione del mondo, ci costringe a prendere atto che spazio e tempo non sono due dimensioni fisse e separate, ma si contraggono e si dilatano, sfumando l'una nell'altra, fino a perdere la loro individualità. La realtà è, dunque, molto più strana di quello che appare. Tutto ciò può sembrare misterioso o comprensibile solo agli addetti ai lavori. Ma non è così.

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.

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.

「はじめに」より 本書で紹介する宇宙思考のポイントは、次の3つです。①宇宙において、見えるもの、そして知ることができることは、視点に依存しており、視点に限られています。

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.

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".

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.

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.

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.

Sarah Cruddas has been looking to the skies her entire life. Her childhood was spent staring at the moon and hearing stories of the space race, and she worked in a fruit factory to fund her love of the subject. Her subsequent career studying astrophysics and becoming a television host and space journalist has seen her report on space exploration and chase launches across the world. In Look Up Sarah explains why she has always been a passionate advocate for why space should matter - to everyone.

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.

This is an indispensable guide to physics that offers readers an overview of the most popular physics topics written in an accessible, irreverent, and engaging manner while still maintaining a tone of wry skepticism. Even the novice will be able to follow along, as the topics are addressed using plain English and (almost) no equations. Veterans of popular physics will also find their nagging questions addressed, like whether the universe can expand faster than light.
