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.

From one of the most exciting and accessible voices in physics, an eye-opening look into the strange and wonderful world of quantum physics and how it is revolutionizing our understanding of the universe. What is the universe made of, and how do we know? For decades, physicists have studied this...

«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.

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?

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.

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.

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.

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.

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.

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.

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?

En El universo en una caja, el profesor de cosmología Andrew Pontzen, explica de una manera clara y rigurosa qué son las simulaciones, esos códigos informáticos con los que los científicos han podido recrear el universo y profundizar en su historia, poniendo a prueba por primera vez ideas centenarias. Esta suerte de manual fundamental para amantes de la astronomía, que aún está desplegando sus capacidades, replantea lo que creemos saber sobre los agujeros negros o la materia cósmica para arrojar nuevas luces sobre nuestra realidad.

In 1965, the great American physicist Richard Feynman famously proclaimed, "I think I can safely say that nobody understands Quantum Mechanics." Is there any wonder why? Particles that pop in and out of existence... Spooky action at a distance that travels faster than light... Infinite universes and branching realities? In this book, we will break through the confusion and reveal to you the most important ideas of Quantum Physics, told through the amazing true story of just 4 bizarre discoveries.
