You are holding something solid. A book. It has weight. Push it; it pushes back. Drop it on your foot and you will know what mass means before any physicist has finished explaining it. Now ask the question almost nobody asks. Where does that weight come from? Not the book. The matter the book is made of. The atoms. The particles inside the atoms. The little buzzing things inside those particles. Where does any of it get the property of being heavy, of being there, of refusing to vanish when you look away? The honest answer is that physics has three answers, and they do not match.

What is life? In this majestic book, Christophe Galfard, celebrated author and former graduate student of Stephen Hawking, takes us on a wonder-filled voyage to answer this question. He guides us from our planet’s birth and the mysterious bacteria that lived billions of years ago, through the extreme evolutionary turns that saw dog-sized sea scorpions and trees covered in scales, to the visionary discoveries of the past two centuries that have allowed us to understand human bodies and imagine alien ones.

What is time? Does it exist? Can it be stopped? Can time's arrow be reversed? Can we ever free ourselves from the seemingly inexorable flow of time? Chronos is a mystery, and not only for us: it was a mystery for our distant ancestors too. In this book, Guido Tonelli guides us along the path to...

In a universe without primitive time, direction emerges from irreversible quantum commitments. The Arrow of Time in a Blockchain Universe explores time not as a flowing river, but as an accumulating ledger of entangled states—validated, recorded, and exponentially costly to reverse. Drawing on philosophy, relativity, quantum gravity, and information theory, Boris Kriger argues that the past is fixed because it is entangled, the future open because it awaits validation, and spacetime itself arises from patterns of mutual information.

For most of human history, people have asked what the world is made of. Atoms, said the ancients. Particles and fields, said the moderns. Vibrating strings, said the late twentieth century. Each answer named some kind of substance — a stuff out of which everything is built. Each answer ran, in the end, into the same wall: a list of unsolved problems that could not be addressed without inventing more substances, more particles, more dimensions of stuff. The framework presented in this book takes a different route.

Twelve light-years from Earth, a star burns quietly in the constellation of the Whale. It is the nearest solitary star that resembles our Sun—a little older, a little cooler, a little poorer in the heavy elements from which planets are made. For sixty years, astronomers have trained the world’s finest instruments on Tau Ceti, searching for planets, for signals, for signs of life. What they have found is something more unexpected and more instructive: a masterclass in the limits of human knowledge.

In 1965, two engineers in New Jersey tried to blame pigeons for a noise that would not go away. The noise turned out to be the oldest light in the universe, still arriving from every direction at once, cooling by one ten-billionth of a degree with every minute that passes. That light has been called the afterglow of the Big Bang — a phrase that is, strictly speaking, wrong. The cosmic background radiation is not the universe being born. It is the universe becoming transparent, roughly three hundred eighty thousand years after an event that had already quietly set the stage.

The earth is bigger than you've been shown and there are undiscovered and secret lands beyond the polar ice. This is the first evidence-based book on the topic. Instead of focusing on anecdotal hearsay, it presents maps, historical accounts, old newspaper clippings, cultural traditions and modern scientific evidence to prove that the mainstream view of the world is false. Equipped with real proof, this book rekindles your sense of exploration and adventure, expands your thinking and helps you dare venture where few have gone before.

By most popular accounts, the universe started with a bang some 13.8 billion years ago. But what happened before the Big Bang? And how do we know it happened at all? Here prominent cosmologist Niayesh Afshordi and science communicator Phil Halper offer a tour of the peculiar possibilities...

«Realmente, este es uno de los mejores capítulos que he visto de todo el ciclo de BBVA», comenta un lector a la charla de José Edelstein en Aprendemos Juntos de BBVA, quienes junto a más de 1,3 M de lectores lo avalan. ¡No os la perdáis! ¿Qué tienen en común un físico griego del siglo III a. C., Beethoven, Stephen Hawking y Gabriel García Márquez? Todos forman parte de este viaje literario y científico por los cielos y sus secretos. En Trece maneras de mirar el cielo, José Edelstein entrelaza astronomía, historia y arte con una elegancia poco habitual en los libros de divulgación.

Rédigés par Becky Smethurst, astrophysicienne à l'université d'Oxford, les dix petits textes qui composent ce livre vous guideront à travers les galaxies et les trous noirs, et vous raconteront pourquoi la matière noire est l'une des énigmes les plus fascinantes du cosmos. Vous apprendrez...

Look up at the night sky. Every star, every galaxy, every wisp of nebula appears perfectly, eternally still. The constellations that Hipparchus cataloged over two thousand years ago remain recognizable tonight. The Universe seems frozen. It is not. Behind that apparent stillness rages a cosmos of extraordinary violence: galaxies colliding over hundreds of millions of years, stars being born and dying in thermonuclear cataclysms, space itself expanding and carrying everything apart. The Universe is not frozen. We are merely too brief to see it move.

For centuries, science has searched for the fundamental "stuff" of the universe — atoms, particles, forces, spacetime. But what if none of those are the true foundation? What if reality is built from something deeper?

Bestselling author and acclaimed physicist Lawrence Krauss offers a paradigm-shifting view of how everything that exists came to be in the first place. “Where did the universe come from? What was there before it? What will the future bring? And finally, why is there something rather than...

The determination of stellar ages is crucial for the development of our understanding of the universe and for constraining theoretical models of galaxy formation and planetary system evolution. The ages of stars provide scientists with timescales to identify the relevant physical processes...

Подобные заголовки часто встречаются в прессе. В них не было бы большой беды, если бы из-за порождаемых мифов не формировалось конспирологическое мировоззрение, отрицающее историю космонавтики и достижения науки. Космическую мифологию легко опровергнуть фактами, но чтобы добраться до них, нужны знания и опыт. Книга Антона Первушина, писателя и научного журналиста, поможет сориентироваться в потоках информации и научиться отделять правду от вымысла.

The first book in this series, The End of Dark Cosmology, showed that ninety-five percent of the universe does not need to be missing. One conceptual correction—separating the cosmological constant from the energy of the quantum vacuum—reproduced the successes of dark matter and dark energy without invoking either. The coupling constant was derived from measured nuclear physics. Zero free parameters. No new particles. No new forces. This book takes the same formula and pushes it to its logical extremes.
