Led by physicist James Trefil and astrophysicist Shobita Satyapal, this book traverses the incredible history of black holes and introduces contemporary developments and theories on still unanswered questions about the enigmatic objects. From the early work of Albert Einstein and Karl Schwarzschild to an insider look at black hole-galaxy connection research led by co-author Satyapa, the comprehensive book surveys an exciting and evolving branch of space science, with topics that include:

This text revolves around a new and unusual view on the most fundamental puzzle of physics. It focuses on the key aspect that makes the role of the time dimension fundamentally different: causality. The implicit and intuitive way by which causality is usually taken for granted is just made explicit and less self-evident, shedding a new light on the gravity-quantum conflict. The case is made that gravity is a necessary condition for a causal universe.

A Short History of Nearly Everything is Bill Bryson's fascinating and humorous quest to understand everything that has happened from the Big Bang to the rise of civilization. He takes subjects that normally bore the pants off most of us, like geology, chemistry, and particle physics, and aims to render them comprehensible to people who have never thought they could be interested in science. In the company of some extraordinary scientists, Bill Bryson reveals the world in a way most of us have never seen it before.

The Los Angeles Times headline screamed: Rocket Scientist Killed in Pasadena Explosion. The man known as Jack Parsons, a maverick rocketeer who helped transform a derided sci-fi plotline into actuality, was at first mourned as a scientific prodigy. But reporters soon uncovered a more shocking story: Parsons had been a devotee of the city’s occult scene.

This audiobook is about pleasure. It's also about pain. Most importantly, it's about how to find the delicate balance between the two, and why now more than ever finding balance is essential. We're living in a time of unprecedented access to high-reward, high-dopamine stimuli: drugs, food, news, gambling, shopping, gaming, texting, sexting, Facebooking, Instagramming, YouTubing, tweeting. The increased numbers, variety and potency are staggering. The smartphone is the modern-day hypodermic needle, delivering digital dopamine 24/7 for a wired generation.

Whether pondering black holes or predicting discoveries at CERN, physicists believe the best theories are beautiful, natural, and elegant, and this standard separates popular theories from disposable ones. This is why, Sabine Hossenfelder argues, we have not seen a major breakthrough in the foundations of physics for more than four decades. The belief in beauty has become so dogmatic that it now conflicts with scientific objectivity: Observation has been unable to confirm mindboggling theories, like supersymmetry or grand unification, invented by physicists based on aesthetic criteria.

In April 1970, during the glory days of the Apollo space program, NASA sent Navy Captain Jim Lovell and two other astronauts on America's fifth mission to the moon. Only 55 hours into the flight of Apollo 13, disaster struck: a mysterious explosion rocked the ship, and soon its oxygen and power began draining away. Written with all the color and drama of the best fiction, Apollo 13 (previously published as Lost Moon) tells the full story of the moon shot that almost ended in catastrophe.

The Large Hadron Collider is the biggest, and by far the most powerful, machine ever built. A project of CERN, the European Organization for Nuclear Research, its audacious purpose is to re-create, in a 16.5-mile-long circular tunnel under the French-Swiss countryside, the immensely hot and dense conditions that existed some 13.7 billion years ago within the first trillionth of a second after the fiery birth of our Universe. The collider is now crashing protons at record energy levels never created by scientists before, and it will reach even higher levels by 2013.

Quantum physics is notable for its brazen defiance of common sense. (Think of Schrödinger's Cat, famously both dead and alive.) An especially rigorous form of quantum contradiction occurs in experiments with entangled particles. Our common assumption is that objects have properties whether or not anyone is observing them, and the measurement of one can't affect the other. Quantum entanglement rejects this assumption, offering impeccable reasoning and irrefutable evidence of the opposite. Is quantum entanglement mystical, or just mystifying?

The grid is an accident of history and of culture, in no way intrinsic to how we produce, deliver and consume electrical power. Yet this is the system the United States ended up with, a jerry-built structure now so rickety and near collapse that a strong wind or a hot day can bring it to a grinding halt. The grid is now under threat from a new source: renewable and variable energy, which puts stress on its logics as much as its components.

In one of the most exciting and accessible explanations of The Theory of Relativity in recent years, Professors Brian Cox and Jeff Forshaw go on a journey to the frontier of 21st century science to consider the real meaning behind the iconic sequence of symbols that make up Einstein's most famous equation, exploring the principles of physics through everyday life.

How does the physics we know today - a highly professionalized enterprise, inextricably linked to government and industry - link back to its origins as a liberal art in Ancient Greece? What is the path that leads from the old philosophy of nature and its concern with humankind's place in the universe to modern massive international projects that hunt down fundamental particles and industrial laboratories that manufacture marvels? This audiobook introduces us to Islamic astronomers and mathematicians calculating the size of the Earth while their caliphs conquered much of it and more.

In a time when our political and cultural perspectives feel more divisive than ever, Tyson provides a much-needed antidote to so much of what divides us, while making a passionate case for the twin engines of enlightenment—a cosmic perspective and the rationality of science. After thinking deeply about how a scientist views the world and about what Earth looks like from space, Tyson has found that terrestrial thoughts change as our brain resets and recalibrates life's priorities, along with the actions we might take in response.

The beauty of fractal patterns and their relation to chaos, as well as the history of chaos, and its uses in the real world and implications for the philosophy of science are all discussed in this Very Short Introduction audiobook.

If you move at high speed, time slows down, space squashes up, and you get heavier. Travel fast enough and you could weigh as much as a jumbo jet, be flattened thinner than a CD without feeling a thing - and live forever! As for the angles of a triangle, they do not always have to add up to 180 degrees. And then, of course, there are black holes. These are but a few of the extraordinary consequences of Einstein's theory of relativity.

What's the Use? asks why there is such a vast gulf between public perceptions of mathematics and reality. It shows how mathematics is vital, often in surprising ways, behind the scenes of daily life. How politicians pick their voters. How an absurd little puzzle solved 300 years ago leads to efficient methods for kidney transplants. How an Irish mathematician's obsession with a new number system improves special effects in movies and computer games. How SatNav relies on at least six mathematical techniques.

Already internationally acclaimed for his elegant, lucid writing on the most challenging notions in modern physics, Sean Carroll is emerging as one of the greatest humanist thinkers of his generation as he brings his extraordinary intellect to bear not only on the Higgs boson and extra dimensions but now also on our deepest personal questions. Where are we? Who are we? Are our emotions, our beliefs, and our hopes and dreams ultimately meaningless out there in the void?

In a time when our political and cultural views feel more polarized than ever, Tyson provides a much-needed antidote to so much of what divides us, while making a passionate case for the twin chariots of enlightenment—a cosmic perspective and the rationality of science. After thinking deeply about how science sees the world and about Earth as a planet, the human brain has the capacity to reset and recalibrates life’s priorities, shaping the actions we might take in response. No outlook on culture, society, or civilization remains untouched.

Astrophysicist Neil deGrasse Tyson has attracted one of the world’s largest online followings with his fascinating, widely accessible insights into science and our universe. Now, Tyson invites us to go behind the scenes of his public fame by unveiling his candid correspondence with people across the globe who have sought him out in search of answers. In this hand-picked collection of 100 letters, Tyson draws upon cosmic perspectives to address a vast array of questions about science, faith, philosophy, life, and of course, Pluto.
