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...

This book challenges the centuries-old pursuit of a final theory in physics by revealing why reality resists scale-independent description. Drawing on developments in effective field theory, renormalization, and the philosophy of science, it argues that physical laws are not universal absolutes but layered tools adapted to context. With clarity and precision, it explores the limits of unification, the power of pragmatic models, and the intellectual maturity required to live with structural incompleteness.

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...

Why is the fine-structure constant approximately one over one hundred and thirty-seven? Why is the proton exactly 1836 times heavier than the electron? Why is gravity so absurdly weak compared to the other forces? For more than a century, physicists have measured the fundamental constants of nature with exquisite precision—yet no one can explain why they have the values they do. Three answers have been proposed. The constants are brute accidents with no deeper explanation. They will one day be derived from a final theory.

Ao longo da história, encontramos grandes pensadores, cientistas e inventores que, num rompante criativo, desafiam nossos paradigmas e nos atiram sem piedade a uma nova realidade, que a princípio pode parecer desconfortável, incompreensível ou até questionável. Mas, afinal, de onde surgem as grandes ideias?

'One of the most accomplished and important science writers of our time' ED YONG 'Chanda Prescod-Weinstein brings light to our universe' ROBIN INCE In The Edge of Space-Time, Chanda Prescod-Weinstein takes readers to the boundaries of the universe, inviting us to spend time at the edge of what...

The universe is watching you. And it's been running tests. Why does observing a particle change how it behaves? Why are physical constants tuned to impossible precision? Why do we see no aliens despite billions of planets where life could exist? Why does the future affect the past in quantum experiments? These aren't mysteries. They're experimental protocols.

What was before the universe? If space is expanding, what is it expanding into? Where did all the matter come from to form planets, stars, and oceans? What is nothing? And if none of these questions can be answered, why do we keep asking them? The Pointless Book asks the biggest questions human beings have ever conceived. The kind of questions that keep you awake at three in the morning. The kind that feel like they should have answers but never do. This book tries to answer them. It reaches for quantum physics, simulation theory, cosmology, philosophy, and religion.

For half a century, cosmology has relied on two invisible ingredients to explain the universe: dark matter, a substance that has never been detected despite decades of experimental search, and dark energy, a repulsive force whose physical nature remains entirely unknown. Together, they are said to constitute ninety-five percent of the cosmos. The remaining five percent—ordinary atoms, light, everything we have ever touched or measured—is treated as a minor addendum to a universe made mostly of darkness. This textbook presents a different cosmology. It is not speculative.

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...

Los últimos descubrimientos sobre el cosmos explicados con sencillezy con una sola fórmula: E= mc2. Es raro el día en el que no aparezca una noticia en los medios de comunicación sobre algún hallazgo de la astrofísica. Exoplanetas, púlsares, agujeros negros, cuásares, Big Bang, universo...

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.

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.

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.

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.

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.
