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.

In Astronomy’s Limitless Journey, astrophysicist Günther Hasinger takes the reader on a journey to the far reaches of the universe?an exciting time travel that begins with the incredibly hot fireball of the Big Bang roughly 13.8 billion years ago and ends in distant eons with its cold, dark demise. In between lie the times in which extensive structures, galaxies, stars, and planets form. As the field of astrophysics and cosmology experiences a “golden age” due to larger telescopes, faster computers, and more sophisticated algorithms, fundamental changes are taking place in our understanding of space and time and of the origin and future of our universe. Hasinger thoroughly explains these fascinating revelations and describes the methods utilized in modern astrophysics.

It has been argued that science fiction (SF) gives a kind of weather forecast - not the telling of a fortune but rather the rough feeling of what the future might be like. The intention in this audiobook is to consider some of these bygone forecasts made by SF and to use this as a prism through which to view current developments in science and technology.

Shaun Usher brings together fascinating correspondence about the universe beyond our planet, containing hopeful thoughts about the future of space travel, awestruck messages penned about the worlds beyond our own and celebrations of the human ingenuity that has facilitated our understanding of the cosmos.

A Journey Through the Universe is a grand tour of the most amazing celestial objects and how they fit together to build the cosmos. There's a whole universe out there.... Imagine you had a spacecraft capable of travelling through interstellar space. You climb in, blast into orbit, fly out of the solar system and keep going. Where do you end up, and what do you see along the way? The answer is: mostly nothing. Space is astonishingly, mind-blowingly empty.

In The Universe, today's most influential science writers explain the science behind our evolving understanding of The Universe and everything in it, including the cutting-edge research and discoveries that are shaping our knowledge. Lee Smolin reveals how math and cosmology are helping us create a theory of the whole universe. Neil Turok analyzes the fundamental laws of nature, what came before the big bang, and the possibility of a unified theory. And much more.

Bringing his cosmic perspective to civilization on Earth, Neil deGrasse Tyson, bestselling author of Astrophysics for People in a Hurry, shines new light on the crucial fault lines of our time–war, politics, religion, truth, beauty, gender, race, and tribalism–in a way that stimulates a...

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.

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...

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.

Als der Physiker Lukas Heuer am LIGO eine merkwürdige Gravitationswellenanomalie entdeckt, hält er sie zuerst für einen Messfehler. Doch Messdaten deuten auf extrem massereiche Objekte hin, die sich der Erde nähern und dabei eine gravitative Schneise durch das Sonnensystem ziehen. Sollte er recht haben, blieben der Menschheit nur wenige Wochen, um den Untergang abzuwenden. Gleichzeitig macht die Archäologin Mira Najafi zur selben Zeit eine ganz andere Entdeckung: Sie findet einen bislang unbekannten Raum in der großen Pyramide von Gizeh, der voller düsterer Prophezeiungen steckt.

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.

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.
