From the #1 bestselling author of The Accidental Billionaires and Bringing Down the House comes a real-life, race-against-time thriller about the scientists and astronauts preparing—right now—to stop a city-killing asteroid from hitting Earth. In 2024, astronomers detected something...

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...

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.

Alles über das All – wissenschaftlich fundiert und allgemein verständlich. Wie warm ist es im Weltraum? Sind Schwarze Löcher wirklich schwarz? Und warum altern Raumfahrer langsamer? Ulrich Walter ist einer von elf Deutschen, die im All waren. Auf seiner Mission mit der Raumfähre Columbia hat er Erfahrungen gemacht, von denen der Großteil der Menschheit nur träumen kann. Verständlich und unterhaltsam erklärt der Astronaut alles Wissenswerte über die Welt und den Weltraum – von der Relativitätstheorie bis zur Dunklen Materie.

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.

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. We are living in an age of scientific advancement on par with that of Copernicus, Galileo, and Newton: a period of discovery that has so fundamentally...

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 SPIEGEL-Bestsellerautor Bill Bryson in der Schule nie Antworten erhalten. Deshalb hat er sich selbst auf die Suche nach ihnen gemacht und eine atemberaubende Reise durch Raum und Zeit angetreten. Dabei entstand ein faktenreiches, kluges und äußerst vergnügliches Hörbuch über die Wunder der Welt– mit all dem Witz und Charme, die Bryson zu einem der beliebtesten Sachbuchautoren unserer Zeit gemacht haben!

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...

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...

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?

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.
