Let us journey, with beloved physicist Carlo Rovelli, into the heart of a black hole. Let us slip beyond its boundary, the horizon, and tumble - on and on - down this crack in the universe. As we plunge, we'll see geometry fold, we'll feel the equations draw tight around us. Eventually, we'll pass it: the remains of a star, deep and dense and falling further far. And then - the bottom. Where time and space end, and the white hole is born.

We’ve long understood black holes to be the points at which the universe as we know it comes to an end. Often billions of times more massive than the Sun, they lurk in the inner sanctum of almost every galaxy of stars in the universe. Recent research, however, has led to a cascade of new discoveries that have revealed an entirely different side to black holes. As the astrophysicist Caleb Scharf reveals in Gravity’s Engines, these chasms in space-time don’t just vacuum up everything that comes near them; they also spit out huge beams and clouds of matter.

Sean Carroll, theoretical physicist and one of this world’s most celebrated writers on science, rewrites the history of 20th-century physics. Already hailed as a masterpiece, Something Deeply Hidden shows for the first time that facing up to the essential puzzle of quantum mechanics utterly transforms how we think about space and time. His reconciling of quantum mechanics with Einstein’s theory of relativity changes, well, everything. Most physicists haven’t even recognized the uncomfortable truth: Physics has been in crisis since 1927.

In Tides: The Science and Spirit of the Ocean, writer, sailor, and surfer Jonathan White takes listeners across the globe to discover the science and spirit of ocean tides. In the Arctic, White shimmies under the ice with an Inuit elder to hunt for mussels in the dark cavities left behind at low tide; in China, he races the Silver Dragon, a 25-foot tidal bore that crashes 80 miles up the Qiantang River; in France, he interviews the monks that live in the tide-wrapped monastery of Mont Saint-Michel; in Chile and Scotland, he investigates the growth of tidal power generation.

Long before space travel was possible, the idea of life beyond Earth transfixed humans. In this fascinating book, astronomer Jon Willis explores the science of astrobiology and the possibility of locating other life in our own galaxy. Describing the most recent discoveries by space exploration missions, including the Kepler space telescope, the Mars Curiosity rover, and the New Horizons probe, Willis asks listeners to imagine - and choose among-five scenarios for finding life.

Welcome to the Universe is a personal guided tour of the cosmos by three of today's leading astrophysicists. Inspired by the enormously popular introductory astronomy course that Neil deGrasse Tyson, Michael A. Strauss, and J. Richard Gott taught together at Princeton, this book covers it all - from planets, stars, and galaxies to black holes, wormholes, and time travel.

Bringing together the best and most interesting science stories appearing in Quanta Magazine over the past five years, Alice and Bob Meet the Wall of Fire reports on some of the greatest scientific minds as they test the limits of human knowledge. It communicates science by taking it seriously, wrestling with difficult concepts, and clearly explaining them in a way that speaks to our innate curiosity about our world and ourselves.

For the first time in four billion years of life on Earth, we are preparing to step out among the stars, not just as lone astronauts or billionaire tech bros, but as a civilization. Dr Adriana Marais has dedicated her life to preparing form extraplanetary settlement, and here, she considers not just the scientific concerns of a multiplanetary existence (like terraforming and life-support systems), but also the ethical responsibilities we must carry with us as we explore new frontiers.

The untold story of the heretical thinkers who challenged the establishment to rethink quantum physics and the nature of reality. Every physicist agrees quantum mechanics is among humanity's finest scientific achievements. But ask what it means, and the result will be a brawl. For a century, most physicists have followed Niels Bohr's Copenhagen interpretation and dismissed questions about the reality underlying quantum physics as meaningless.

You've got questions: about space, time, gravity and the odds of meeting your older self inside a wormhole. All the answers you need are right here. An eminent physicist at CERN and the cartoonist behind the hugely successful PhD Comics answer the most important, most outrageous and funniest questions about everything.

In this brilliant exploration of our cosmic environment, the renowned particle physicist and New York Times best-selling author of Warped Passages and Knocking on Heaven's Door uses her research into dark matter to illuminate the startling connections between the farthest reaches of space and life here on Earth.

In a rare blend of scientific insight and writing as elegant as the theories it explains, Brian Greene, one of the world's leading string theorists, peels away the layers of mystery surrounding string theory to reveal a universe that consists of 11 dimensions where the fabric of space tears and repairs itself, and all matter-from the smallest quarks to the most gargantuan supernovas-is generated by the vibrations of microscopically tiny loops of energy.

Gravity controls everything from the falling of an apple to the rising of ocean’s tides to the motions of the heavens above. If you’ve ever wondered how this most puzzling force works across our entire universe, you will be delighted by this 24-part course that is accessible to any curious person, regardless of your science education. No other product on the market presents the subject of gravity in as much detail as this course, which will follow the past 400 years of research and experimentation in the field.

Science starts to get interesting when things don'’t make sense. Even today, there are experimental results that the most brilliant scientists can neither explain nor dismiss. In the past, similar anomalies have revolutionised our world: in the 16th century, a set of celestial irregularities led Copernicus to realise that the Earth goes around the sun and not the reverse. In 13 Things That Don'’t Make Sense, Michael Brooks meets thirteen modern-day anomalies that may become tomorrow'’s breakthroughs.

Alexander von Humboldt (1769-1859) is the great lost scientist: more things are named after him than anyone else. There are towns, rivers, mountain ranges, the ocean current that runs along the South American coast; there's a penguin, a giant squid - even the Mare Humboldtianum on the moon. His colourful adventures read like something out of a Boy's Own story.

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.

A series of glasses of transparent liquids is in front of you: but which will quench your thirst and which will kill you? And why? Why does one liquid make us drunk and another power a jumbo jet? Sometimes dangerous, often delightful and always fascinating, discover the secret lives of liquids, from one of our best known scientists. From the best-selling author of Stuff Matters comes a fascinating tour of the world of these surprising or sinister substances - the droplets, heartbeats and ocean waves we encounter day to day.

In the 18th century, the British minister and mathematician Thomas Bayes devised a theorem that allowed him to assign probabilities to events that had never happened before. It languished in obscurity for centuries until computers came along and made it easy to crunch the numbers. Now, as the foundation of big data, Bayes's formula has become a linchpin of the digital economy. But here's where things get interesting: Bayes's theorem can also be used to lay odds on the existence of extraterrestrial intelligence, and on the biggest question of all: how long will humanity survive?

Big History, the field that studies the entire known past of our universe to give context to human existence, has so far been the domain of historians. Geologist Walter Alvarez - best known for his Impact Theory explaining dinosaur extinction - makes a compelling case for a new, science-first approach to Big History.

Something strange is going on in the cosmos. Scientists are uncovering a catalogue of weird phenomena that simply can’t be explained by our long-established theories of the universe. Particles with unbelievable energies are bursting from beneath the Antarctic ice. Unknown forces seem to be tugging on the basic building blocks of matter. Stars are flying away from us far faster than anyone can explain. In Space Oddities, Harry Cliff provides a riveting look at the universe’s most confounding puzzles.
