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.

A meteorite is a mass of stone or metal which has reached the earth's surface from outer space. There are various names for a meteorite depending on where it is situated. While it is traveling in space, it is referred to as a "meteoroid". When it passes through the earth's atmosphere and produces a fiery streak in the sky, known as a "shooting star", it is called a "meteor".

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.

What building did Elvis leave last? Get the answers to these and countless other vexing questions in All Facts Considered. Guaranteed to enlighten even the most seasoned trivia buff, this treasure trove of "who knew?" factoids spans a wide range of intriguing subjects.

With the ongoing advancement of AI and other technologies, our world is becoming increasingly intelligent. From chatbots to innovations in brain-computer interfaces to the possibility of superintelligences leading to the Singularity later this century, our reality is being transformed before our eyes. This is commonly seen as the natural result of progress, but what if there's more to it than that? What if intelligence is an inevitability, an underlying property of the universe?

Signs are meant to point us toward something: Jesus. Story in the Stars takes an in-depth look at the Bible and all the signs God mapped out through constellations, planets, and even the way the Earth is tilted. We are uniquely designed by God, and he loves us so much that he ensured a way for all inhabitants of the Earth, through all of time, to see the messages of salvation and redemption that he painted in the stars.

In this remarkable audiobook, Professor Richard Wiseman presents a pioneering study of the mind-set that took humanity to the moon and shows how you can harness and use it to achieve the extraordinary in your everyday life. Combining personal interviews, mission archives and cutting-edge psychology, Wiseman embarks on the ultimate voyage through inner space. Along the way he identifies eight key principles that make up the Apollo mind-set, including how pessimism is crucial to success and how fear and tragedy can be transformed into hope and optimism.

How many Carl Sagan fans know that while the renowned scientist was at Stanford University, he produced a controversial paper, funded by a NASA research grant, that concludes that ancient alien intervention may have sparked human civilization? Author Donald L. Zygutis lays out a compelling case that points to a cover-up by the Pentagon and NASA, who may have buried it soon after it was written. How significant is the Stanford paper?

The question of man’s place in the extended universe has been pondered by every known culture since the beginning of recorded history. Lacking the means to prove otherwise, discussions of an alternative to Earth’s solitary existence have remained conceptual. The ongoing debate is spurred by the appearance of unexplainable phenomena through the centuries in the atmosphere and the space beyond, so much so that contact with alien civilizations has been depicted in some of the most ancient examples of representational art.

Written in simple and accessible language, this nontechnical introduction to cosmology, or the creation and development of the universe, explains the discipline, covers its history, details the latest developments, and explains what is known, what is believed, and what is purely speculative. In addition, the author discusses the development of the Big Bang theory, and more speculative modern issues like quantum cosmology, superstrings, and dark matter.

More than 30 years ago, Frank White coined the term "overview effect", to describe the cognitive shift in awareness that results from the experience of viewing Earth from orbit or the moon. He found, that with great consistency, this experience profoundly affects space travelers' worldviews - their perceptions of themselves and our planet and our understanding of the future. White found that astronauts know from direct experience what the rest of us know only intellectually: We live on a planet that is like a natural spaceship moving through the universe.

Could there be a civilisation on a mote of dust? How much of your fate have you made? Who cleans the universe? Through more than 50 Koans - pleasingly paradoxical vignettes following the ancient Zen tradition - leading physicist Anthony Aguirre takes the listener across the world from Japan to Italy, and through ideas spanning the age, breadth and depth of the Universe. Using these beguiling Koans and a flair for explaining complex science, Aguirre covers cosmic questions that scientific giants from Aristotle to Galileo to Heisenberg have grappled with.

Dark matter, an elusive and invisible substance, constitutes a significant portion of the universe's mass, detectable only through its gravitational effects. First proposed by Fritz Zwicky in the 1930s and supported by Vera Rubin's observations in the 1970s, dark matter does not interact with light, making it invisible. Scientists explore its nature through various theoretical candidates like WIMPs, axions, and sterile neutrinos. While detection remains challenging, methods include underground labs, particle accelerators, and indirect observations. Ongoing research promises to unravel this ...

Olá, meu nome é Davi Barbosa, sou doutorando em Astronomia e Astrofísica em Lisboa-Portugal. Já teve teve alguma dúvida sobre conciliar ciência e fé? Já achou que a ciência e a fé parecem se contradizer GrandeMente? Esse PodCast é pra vc! Venha descobrir como GrandeMente a Ciência e Fé andam muito mais juntas do que vc poderia imaginar, e como as descobertas científicas mais atuais e uma boa interpretação bíblica nos mostram que é muito razoável atribuir a causa do Universo e da Vida a uma GrandeMente.

With wonder, wit, and flair - and in record time and space - geophysicist David Bercovici explains how everything came to be everywhere, from the creation of stars and galaxies to the formation of Earth's atmosphere and oceans to the origin of life and human civilization. Bercovici marries humor and legitimate scientific intrigue, rocketing listeners across nearly 14 billion years and making connections between the essential theories that give us our current understanding of topics as varied as particle physics, plate tectonics, and photosynthesis.

A sweeping account of the century of experimentation that confirmed Einstein's general theory of relativity, bringing to life the science and scientists at the origins of relativity, the development of radio telescopes, the discovery of black holes and quasars, and the still unresolved place of gravity in quantum theory.

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.

What's it like to travel at more than 850 MPH, riding in a supersonic T-38 twin turbojet engine airplane? What happens when the space station toilet breaks? How do astronauts "take out the trash" on a spacewalk, tightly encapsulated in a space suit with just a few layers of fabric and Kevlar between them and the unforgiving vacuum of outer space?

The hunt for the Higgs particle has involved the biggest, most expensive experiment ever. So exactly what is this particle? Why does it matter so much? What does it tell us about the universe? Was finding it really worth all the effort? The short answer is yes. The Higgs field is proposed as the way in which particles gain mass - a fundamental property of matter. It's the strongest indicator yet that the Standard Model of physics really does reflect the basic building blocks of our universe. Little wonder the hunt and discovery of this new particle produced such intense media interest.
