Science Cosmology

Years ago, cosmologist Stephon Alexander received life-changing advice: to discover real physics, he needed to stop memorizing and start taking risks. In Fear of a Black Universe, Alexander shows that great physics requires us to think outside the mainstream - to improvise and rely on intuition. His approach leads him to three principles that shape all theories of the universe: the principle of invariance, the quantum principle, and the principle of emergence. Alexander uses them to explore some of physics' greatest mysteries.

You are reading the word now right now. But what does that mean? What makes the ephemeral moment "now" so special? Its enigmatic character has bedeviled philosophers, priests, and modern-day physicists from Augustine to Einstein and beyond. Einstein showed that the flow of time is affected by both velocity and gravity, yet he despaired at his failure to explain the meaning of now. Equally puzzling: Why does time flow? Some physicists have given up trying to understand and call the flow of time an illusion.

There are deep connections between stars and atoms, between the cosmos and the microworld. Just six numbers, imprinted in the "Big Bang", determine the essential features of our entire physical world. Moreover, cosmic evolution is astonishingly sensitive to the values of these numbers. If any one of them were "untuned", there could be no stars and no life. This realization offers a radically new perspective on our universe, our place in it, and the nature of physical laws.

Humanity has reached a critical moment. Our world is unsettled and rapidly changing, and we face existential risks over the next century. Various outcomes - good and bad - are possible. Yet our approach to the future is characterized by short-term thinking, polarizing debates, alarmist rhetoric, and pessimism. In this short, exhilarating book, renowned scientist and best-selling author Martin Rees argues that humanity’s prospects depend on our taking a very different approach to planning for tomorrow.

In the beginning was the Big Bang: an unimaginably hot fire almost fourteen billion years ago in which the first elements were forged. The physical theory of the hot nascent universe—the Big Bang—was one of the most consequential developments in twentieth-century science. And yet it leaves many questions unanswered: Why is the universe so big? Why is it so old? What is the origin of structure in the cosmos? In An Infinity of Worlds, physicist Will Kinney explains a more recent theory that may hold the answers to these questions and even explain the ultimate origins of the universe.

A hilarious guide to what's real (and what's not) in our vast, beautiful (and terrifying) universe.

A respected physics professor and author breaks down the great debate over the big bang and the continuing quest to understand the fate of the universe.

On March 21, 2013, the European Space Agency released a map of the afterglow of the big bang. Taking in 440 sextillion kilometers of space and 13.8 billion years of time, it is physically impossible to make a better map: We will never see the early universe in more detail. On the one hand, such a view is the apotheosis of modern cosmology; on the other, it threatens to undermine almost everything we hold cosmologically sacrosanct.

What is the nature of the material world? How does it work? What is the universe and how was it formed? What is life? Where do we come from and how did we evolve? How and why do we think? What does it mean to be human? How do we know? There are many different versions of our creation story. This book tells the version according to modern science. It is a unique account, starting at the Big Bang and travelling right up to the emergence of humans as conscious intelligent beings, 13.8 billion years later.

One of the most peculiar and possibly unique features of humans is the vast amount of information we carry outside our biological selves. But in our rush to build the infrastructure for the 20 quintillion bits we create every day, we’ve failed to ask exactly why we’re expending ever-increasing amounts of energy, resources, and human effort to maintain all this data. Drawing on deep ideas and frontier thinking in evolutionary biology, computer science, information theory, and astrobiology, Caleb Scharf argues that information is, in a very real sense, alive - an aggregate lifeform.

Why are we here? Human beings have asked themselves this question for centuries. Modern science largely argues that human beings are chance products of a purposeless universe, but other traditions believe humanity has an essential role and responsibility in creation. Lachman brings together many strands of esoteric, spiritual and philosophical thought to form a counter-argument to the nihilism that permeates the twenty-first century.

On April 10, 2019, award-winning astrophysicist Heino Falcke presented the first image ever captured of a black hole at an international press conference - a turning point in astronomy that Science magazine called the scientific breakthrough of the year. That photo was captured with the unthinkable commitment of an intercontinental team of astronomers who transformed the world into a global telescope. While this image achieved Falcke’s goal in making a black hole “visible” for the first time, he recognizes that the photo itself asks more questions for humanity than it answers.

In The Genesis Enigma, respected evolutionary biologist Andrew Parker explains each parallel between Genesis and science in detail--and the closer he looks, the more amazing the parallels become. But the Genesis account has no right to be correct. The author or authors could not have known these things happened in this order, and with the highlights science has come to recognize.

A physicist speeds across space, time, and everything in between showing that our elegant universe from the Higgs boson to antimatter to the most massive group of galaxies is shaped by hidden symmetries that have driven all our recent discoveries about the universe and all the ones to come. Why is the sky dark at night? Is it possible to build a shrink-ray gun? If there is antimatter, can there be antipeople? Why are past, present, and future our only options? Are time and space like a butterfly's wings? No one but Dave Goldberg, the coolest nerd physicist on the planet, could give a hyper-drive tour of the universe like this one.

Humans have long sought to comprehend the enormities of cosmic space and time. Here, best selling science writer Timothy Ferris tells the story of that quest. He interweaves the majestic themes of astronomy, physics, religion, and philosophy with fresh and lasting portraits of the men and women who created what has been called our society's most precious treasure - its conception of the universe at large.

Stephen Hawking has dazzled listeners worldwide with a string of best sellers exploring the mysteries of the universe. Now, for the first time, perhaps the most brilliant cosmologist of our age turns his gaze inward for a revealing look at his own life and intellectual evolution. My Brief History recounts Stephen Hawking’s improbable journey, from his postwar London boyhood to his years of international acclaim and celebrity. This concise, witty, and candid account introduces listeners to a Hawking rarely glimpsed in previous books.

Find out about astronomical phenomena and take a tour of the solar system. This easy-to-follow audiobook also explains the science behind the wonders of the sky.

The young field of quantum mechanics holds out the promise that some of humanity's wildest dreams may be realized. Serious scientists, working off of theories first developed by Einstein and his colleagues 70 years ago, have been investigating the phenomenon known as "entanglement," one of the strangest aspects of the strange universe of quantum mechanics. New experiments suggest it does happen, and that it may lead to unbreakable codes, and even teleportation...

Two bestselling authors first met in a televised Caltech debate on “the future of God,” one an articulate advocate for spirituality, the other a prominent physicist. This remarkable book is the product of that serendipitous encounter and the contentious - but respectful - clash of worldviews that grew along with their friendship.

Of all the many unexplained phenomena, experiences, and objects in the world, the ones that hold a great deal of fascination for most people are known as "ancient anomalies". These are ancient objects by scientific measure but in form or construction that appear to be relatively modern. They are impossible fossils, out-of-time technology, anachronistic artifacts, or even ancient ruins. In other words, if our history of the world is correct, they just should not exist.
