Mercury, a lifeless victim of the Sun’s expanding power. Venus, once thought to be lush and fertile, now known to be trapped within a toxic and boiling atmosphere. Mars, the red planet, doomed by the loss of its atmosphere. Jupiter, twice the size of all the other planets combined, but insubstantial. Saturn, a stunning celestial beauty, the jewel of our Solar System. Uranus, the sideways planet and the first ice giant. Neptune, dark, cold and whipped by supersonic winds. Pluto, the dwarf planet, a frozen rock. 

This audio edition is narrated with dazzling enthusiasm by the author, Dr Becky Smethurst. Right now, you are orbiting a black hole. The Earth orbits the Sun, and the Sun orbits the centre of the Milky Way: a supermassive black hole, the strangest and most misunderstood phenomenon in the galaxy...

Brought to you by Penguin. From the world-renowned physicist and best-selling author of The Elegant Universe comes this captivating exploration of deep time and humanity's search for purpose In both time and space, the cosmos is astoundingly vast, and yet is governed by simple, elegant...

Read by the author, Harry Cliff. 'As fascinating as its title suggests . . . Cliff recounts with vivid clarity the stories of some of the most striking oddnesses that have lit up the landscape of modern physics.' – Philip Pullman Newly discovered strangenesses could transform our understanding...

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.

A lighthearted yet profound guide to the realms of higher consciousness and the ultimate nature of reality. Explains some of the most difficult concepts of physics and heightened consciousness in ways that are easily understood. Presents a model for the interaction of the universe and...

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.

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!

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...

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.

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...
