Most of us have heard of black holes and supernovas, galaxies and the big bang. But few of us understand more than the bare facts about the universe we call home. What is really out there? How did it all begin? Jo Dunkley begins in Earth's neighborhood, explaining the nature of the solar system, the stars in our night sky, and the Milky Way. She then moves out past nearby galaxies - and back in time - to the horizon of the observable universe, which contains over a hundred billion galaxies, each with billions of stars, many orbited by planets, some of which may host life.

When Charles Darwin finished The Origin of Species, he thought that he had explained every clue but one. Though his theory could explain many facts, Darwin knew that there was a significant event in the history of life that his theory did not explain. During this event, the "Cambrian explosion", many animals suddenly appeared in the fossil record without apparent ancestors in earlier layers of rock. In Darwin's Doubt, Stephen C. Meyer tells the story of the mystery surrounding this explosion of animal life.

Where did the universe come from? What was there before it? What will the future bring? And finally, why is there something rather than nothing? Krauss’ answers to these and other timeless questions, in a wildly popular lecture on YouTube, has attracted almost a million viewers. One of the few prominent scientists to have actively crossed the chasm between science and popular culture, Krauss reveals that modern science is indeed addressing the question of why there is something rather than nothing—with surprising and fascinating results.

Brad Steiger, the world-renowned authority on unexplained phenomena, presents a collection of UFO encounters and abductions. His provocative theories provide answers to the most puzzling questions: Why are they here? What do they want? And how will they change the fate of the human race?

How would Saturn’s rings look from a spaceship sailing just above them? If you were falling into a black hole, what’s the last thing you’d see before your spaghettification? What would it be like to visit the faraway places we currently experience only through high-powered telescopes and robotic emissaries? Faster-than-light travel may never be invented, but we can still take the scenic route through the universe with renowned astronomer and science communicator Philip Plait.

We know the universe had a beginning. With the Big Bang, it expanded from a state of unimaginable density to an all-encompassing cosmic fireball to a simmering fluid of matter and energy, laying down the seeds for everything from black holes to one rocky planet orbiting a star near the edge of a spiral galaxy that happened to develop life as we know it. But what happens to the universe at the end of the story? And what does it mean for us now?

From the best-selling author of The Emperor’s New Mind and The Road to Reality, a groundbreaking book that provides new views on three of cosmology’s most profound questions: What, if anything, came before the Big Bang? What is the source of order in our universe? What is its ultimate future?

Was there a beginning of time? Could time run backwards? Is the universe infinite, or does it have boundaries? These are just some of the questions considered in an internationally acclaimed masterpiece by one of the world's greatest thinkers. It begins by reviewing the great theories of the cosmos, from Newton to Einstein, before delving into the secrets which still lie at the heart of space and time, from the big bang to black holes, via spiral galaxies and strong theory.

The Trouble with Physics argues that a limited notion of time is holding physics back. It's time for a major revolution in scientific thought. The reality of time could be the key to the next big breakthrough in theoretical physics. What if the laws of physics themselves were not timeless? What if they could evolve? Time Reborn offers a radical new approach to cosmology that embraces the reality of time and opens up a whole new universe of possibilities.

One of the leading physicists of her generation, Dr. Chanda Prescod-Weinstein is also one of fewer than one hundred Black American women to earn a PhD from a department of physics. Her vision of the cosmos is vibrant, buoyantly nontraditional, and grounded in Black and queer feminist lineages. Dr. Prescod-Weinstein urges us to recognize how science, like most fields, is rife with racism, misogyny, and other forms of oppression. She lays out a bold new approach to science and society, beginning with the belief that we all have a fundamental right to know and love the night sky.

The author presents evidence from highly credible sources that you are an eternal spiritual being that is temporarily residing in what might be regarded as a kind of spacesuit—aka a human body—that allows you to operate in physical reality. He suggests that you will likely exist forever, albeit in other realities that are quite different from this one. He urges you to read this book, weigh the evidence, and then ask yourself, “Does knowing I will exist forever change how I think about life?” He also suggests that you give some thought to what you might do to make the most of the ...

The marvelous complexity of the universe emerges from several deep laws and a handful of fundamental constants that fix its shape, scale, and destiny. Where did these laws and these constants come from? And why are the laws so fruitful when written in the language of mathematics? Author Peter Atkins considers the minimum effort needed to equip the universe with its laws and its constants. He explores the origin of the conservation of energy, of electromagnetism, of classical and quantum mechanics, and of thermodynamics, showing how all these laws spring from deep symmetries.

Does the universe embody beautiful ideas? Artists as well as scientists throughout human history have pondered this "beautiful question". With Nobel laureate Frank Wilczek as your guide, embark on a voyage of related discoveries, from Plato and Pythagoras up to the present. Wilczek's groundbreaking work in quantum physics was inspired by his intuition to look for a deeper order of beauty in nature.

Recent polls report that 96-percent of Americans believe in God, and 73-percent believe that angels regularly visit Earth. Why is this? Why, despite the rise of science, technology, and secular education, are people turning to religion in greater numbers than ever before? Why do people believe in God at all?

The final book from Professor Stephen Hawking, the best-selling author of A Brief History of Time and arguably the most famous scientist of our age, Brief Answers to the Big Questions is a profound, accessible and timely reflection on the biggest questions in science. Professor Hawking was a brilliant theoretical physicist, an influential author and thinker and a great popular communicator.

In Into the Unknown, astrophysicist Kelsey Johnson takes us to the edge of scientific understanding about the universe: What caused the Big Bang? What happens inside black holes? Are there other dimensions? She doesn’t just celebrate what we know but rather what we don’t, and asks what it means if we never find that knowledge. Exploring the convergence of science, philosophy, and theology, Johnson argues we must reckon with possibilities—including those that may be beyond human comprehension.

Over the past few decades, a handful of scientists have been racing to explain a disturbing aspect of our universe: only four percent of it consists of the matter that makes up you, me, our books, and every star and planet. The rest is completely unknown. Richard Panek tells the dramatic story of the quest to find this “dark” matter and an even more bizarre substance called “dark energy”. This is perhaps the greatest mystery in all of science, and solving it will bring fame, funding, and certainly a Nobel Prize.

What does it mean to be human, to live on planet Earth, in the universe as it is now understood? Best-selling author and mathematical cosmologist Brain Swimme takes us on a journey through the cosmos in search of the “new story” that is developing in answer to this age-old question.

In this vibrant, eye-opening tour of milestones in the history of our universe, Chris Impey guides us through space and time, leading us from the familiar sights of the night sky to the dazzlingly strange aftermath of the Big Bang. What if we could look into space and see not only our place in the universe but also how we came to be here? As it happens, we can. Because it takes time for light to travel, we see more and more distant regions of the universe as they were in the successively greater past.

Icy, rocky, sometimes dusty, always mysterious – comets and asteroids are among the Solar System's very oldest inhabitants, formed within a swirling cloud of gas and dust in the area of space that eventually hosted the Sun and its planets. Locked within each of these extra-terrestrial objects is the 4.6-billion-year wisdom of Solar System events, and by studying them at close quarters using spacecraft we can coerce them into revealing their closely-guarded secrets. This offers us the chance to answer some fundamental questions about our planet and its inhabitants.
