A Short History of Nearly Everything meets Astrophysics for People in a Hurry in this humorous, accessible exploration of how meteorites have helped not only build our planet but steered the evolution of life and human culture. The Solar System. Dinosaurs. Donkey Kong. What is the missing link?...

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.

We have long treated uncertainty as a flaw to be eliminated—a gap in knowledge, a defect in reality itself. But what if uncertainty is not optional—what if it is imperative? In this radical and rigorously argued book, Boris Kriger proposes The Law of Imperative Uncertainty: Any system capable of sustained complexity must permit exceptions to its laws in the form of persistent uncertainty and probabilistic deviation. A perfectly deterministic universe—closed, exceptionless, rigid—cannot endure.

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.

A radical new vision of reality from one of the great minds of our time, mapping a watershed moment in both physics and philosophy. “Carlo Rovelli is the best thinker out there articulating physics, philosophy, and literature. There simply are no scientists of his caliber who also are...

Der internationale Bestseller – jetzt auf dem neuesten Stand der Wissenschaft! Wie war das eigentlich mit dem Urknall? Warum starben die Dinosaurier aus? Was wiegt die Erde? Und wie ist das überhaupt möglich – die Erde zu wiegen? Auf diese und viele weitere Fragen hat...

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?

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...

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.

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...

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.

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.

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...

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.

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.

Measuring distances in the Universe is one of the most demanding intellectual achievements in the history of science. The objects studied by astronomy are separated from us by such vast expanses that no direct measurement is possible. Every number describing the scale of the cosmos must therefore be inferred indirectly, through light, motion, geometry, and carefully constructed physical models.

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.
