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 également ce qu'il y avait avant le Big Bang, pourquoi nous ne sommes peut-être pas seuls dans l'Univers, tout ce que l'on ignore, ce qu'il reste à découvrir et bien d'autres choses.

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: bouncing and cyclic universes, time loops, creations from nothing, multiverses, black hole births, string theories, and holograms. Along the way, they offer both a call for new physics and a riveting story of scientific debate.

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...

How learning to “listen” to the universe using radio waves has revolutionized our understanding of everything from gravity to little green men. “Passionate and witty” —Publishers Weekly, starred review In space, no one can hear you scream. But the universe is far from silent. It’s...

Brought to you by Penguin. If you met an alien, what might it be like? Ever since childhood, astrophysicist Neil deGrasse Tyson has wanted to be abducted by aliens. Here, he draws upon a lifetime’s fascination to explore the science of alien life – and to offer a practical guide to your...

In The Edge of Space-Time, Chanda Prescod-Weinstein takes listeners to the boundaries of the universe, inviting us to spend time at the edge of what we know about space-time – and about ourselves. Guided by her conviction that science is for everybody, Prescod-Weinstein renders accessible some of the most abstract concepts of theoretical physics and draws on poetry and popular culture – from Queen Latifah to Lewis Carroll to Big K.R.I.T. to Sun Ra and Star Trek – to tell fascinating stories about the fundamental quantum nature of space-time and everything inside of it.

A boundary-breaking astrophysicist reimagines the universe—and our place within it—in this audacious journey through the Nine Realms of the cosmos. The universe gave rise to everything: stars and cells, minds and memories, purpose and pain. But it doesn’t care about us. It follows its own...

The question "what came first?" has shaped human thought since its earliest stirrings, from theological first principles to the search for base reality in simulation theory. This demand for ultimate origins appears so natural that it goes unnoticed, like air supporting breath without announcing itself. But what if this demand contains a hidden error? Boris Kriger's groundbreaking work argues that for certain closed hierarchical structures, the question of primary foundation is not merely unanswered—it is unanswerable.

A fresh, charming, socially conscious tour of the mysteries of space-time, from the award-winning author of The Disordered Cosmos In her highly acclaimed debut, distinguished cosmologist and particle physicist Dr. Chanda Prescod-Weinstein shared with her audience an abiding sense of wonder at...

The Earth, that trusty old spinning marble we call home, isn't a sphere at all. No, according to some, it is flat as a pancake (or a pizza, if we're being generous). Yet for thousands of people, this is reality – or at least their version of it. The Flat Earth phenomenon isn't new. It has ancient roots, woven into the cosmologies of civilizations long past. But what's fascinating is how, in a time when we can send rovers to Mars, carry pocket supercomputers, and live-stream cat videos from space stations, this belief has not only persisted but thrived.

Quasars are the brightest sustained phenomena in the known universe—engines of light powered by supermassive black holes devouring matter at the centers of distant galaxies. But they are more than cosmic spectacles. Every beam of quasar light that crosses the universe accumulates an extraordinarily detailed record of the gas, matter, and structure it passes through. The intergalactic medium writes its autobiography in the spectra of quasars, using absorption lines as words and sightlines as sentences.

Pour retracer l'histoire du Système solaire, Alessandro Morbidelli suit cette règle de Sherlock Holmes : « lorsque vous avez éliminé l'impossible, ce qui reste, si improbable soit-il, est nécessairement la vérité. » En éliminant progressivement les hypothèses les plus simples (les planètes se sont formées sur leurs orbites actuelles) mais démenties par les observations (les orbites des petits corps sont alors inexplicables), Alessandro Morbidelli et ses collègues sont parvenus au « modèle de Nice » pour décrire les déplacements et perturbations des corps du Système solaire.

Can you ever truly experience your own death? Quantum physics says no. Everyone dies. But what if, from your own perspective, death is impossible to experience? Reality doesn't follow one timeline. Every quantum event creates branching worlds where all outcomes happen. You exist in branches where you survived—but not in branches where you died.

For a century, physicists and philosophers have treated quantum mechanics as an anomaly—a realm where particles tunnel through barriers, exist in multiple states at once, and refuse to reveal their properties until observed. The quantum world has been called bizarre, counterintuitive, and fundamentally strange. But what if this strangeness was never in the world at all? What if it was only ever in our expectations? Nothing Strange About Quantum Strangeness offers a radical reframing.

This book explains why events in the world cannot always be understood as the result of separate things influencing one another locally. Starting from a well-established result in modern physics, it shows that some correlations observed in nature cannot be explained by assuming that each object carries its own independent properties and that all influence spreads step by step through space. The book examines the theorem that establishes this limit and the experiments that confirm it.

Reality is not what it seems. Not fixed. Not silent. Not separate from the one who observes it. Quantum experiments reveal seams in the world… places where information appears without traveling… where outcomes wait for attention… where time behaves like something far more flexible than a river. These seams form a doorway. A narrow line where darkness gives way to light… where the familiar dissolves into the possible… where a question becomes the beginning of understanding. This book does not claim answers. It offers a key. If you have ever sensed something beneath the surface… Step closer.

Originally published in 1926, The Russell Genero-Radiative Concept is a concise and provocative exposition of Walter Russell’s cyclic theory of continuous motion. In this rare work, Russell outlines a universe governed not by linear mechanics, but by rhythmic balance—where all matter, energy, and motion arise from the interplay of generative and radiative forces.

Avez-vous déjà ressenti une profonde curiosité pour les mystères de l’Univers ? Vous êtes-vous demandé ce qui se trouve au-delà de ce que vos yeux peuvent voir, dans les profondeurs du cosmos ? Voulez-vous comprendre ces énigmes qui, pendant des décennies, ont défié même les esprits les plus brillants ?

In virtually all fields of human endeavor, Classical Athens was so much at the forefront of dynamism and innovation that the products of its most brilliant minds remain not only influential but still relevant to this day. To the ancient Greeks, the cosmos was ordered and harmonious. Consequently, reason and intellect were considered the architects of all art and craftsmanship. The absolute perfection of form was sought in everything and the Greek passion for simplicity, elegance, harmony, and beauty is to be found everywhere, particularly in architecture.
