It has been nearly 100 years since the Apollo moon landings, when Jack and Vladimir, two astronauts on a mission to Venus, discover a mysterious void related to indigenous life on the planet. Subsequently more voids are detected on Earth, Mars, Titan, and, quite ominously, inside a planetoid emerging from the Kuiper belt. Jack is sent to investigate the voids in the Solar System and intercept the planetoid - which, as becomes increasingly clear, is inhabited by alien life forms.

In 1974 a message was beamed towards the stars by the giant Arecibo telescope in Puerto Rico, a brief blast of radio waves designed to alert extraterrestrial civilizations to our existence. Of course, we don't know if such civilizations really exist. But for the past six decades a small cadre of researchers have been on a quest to find out, as part of SETI, the search for extraterrestrial intelligence.

Where is the best place to find life beyond Earth? We often look to Mars as the most promising site in our solar system, but recent scientific missions have revealed that some of the most habitable real estate may actually lie farther away. Beneath the frozen crusts of several of the small, ice-covered moons of Jupiter and Saturn lurk vast oceans that may have been in existence for as long as Earth, and together may contain more than 50 times its total volume of liquid water. Could there be organisms living in their depths?

In this revised and expanded edition of Richard Dolan's previous classic on the UFO subject, he brings the listener through the tumultuous journey of the UFO/UAP subject through the early 2020s. This includes a detailed treatment of the changes to our public discussion of UFOs since 2017 and what is the likely end point of this new direction. But Dolan provides much more than this, including providing critical context of the UFO subject within the broader social, political, and technological developments of our world, something that makes him unique among UFO researchers.

In the New York Times bestseller Extraterrestrial, Avi Loeb, the longest serving Chair of Harvard’s Astronomy Department, presented a theory that shook the scientific community: our solar system, Loeb claimed, had likely been visited by a piece of advanced alien technology from a distant star. This provocative and persuasive argument opened millions of minds internationally to the vast possibilities of our universe and the existence of intelligent life beyond Earth.

Scientists are confident that life exists elsewhere in the universe. Yet rather than taking a realistic approach to what aliens might be like, we imagine that life on other planets is the stuff of science fiction. The time has come to abandon our fantasies of space invaders and movie monsters and place our expectations on solid scientific footing. But short of alien's landing in New York City, how do we know what they are like?

In late 2017, scientists at a Hawaiian observatory glimpsed an object soaring through our inner solar system, moving so quickly that it could only have come from another star. Avi Loeb, Harvard’s top astronomer, showed it was not an asteroid; it was moving too fast along a strange orbit, and left no trail of gas or debris in its wake. There was only one conceivable explanation: the object was a piece of advanced technology created by a distant alien civilization.

The number-one best-selling author of The Future of the Mind traverses the frontiers of astrophysics, artificial intelligence, and technology to offer a stunning vision of man's future in space, from settling Mars to traveling to distant galaxies. Formerly the domain of fiction, moving human civilization to the stars is increasingly becoming a scientific possibility - and a necessity. Whether in the near future due to climate change and the depletion of finite resources or in the distant future due to catastrophic cosmological events, humans will one day need to leave Earth.

Three of the most important words in science are I don't know. Not knowing implies a universe of opportunities—the possibility of discovery and surprise. Our understanding of science has advanced immeasurably over the last 500 years, yet many fundamental mysteries of existence persist: How did our universe begin? How big is the universe? Is time travel possible? What’s at the center of a black hole? How did life on Earth arise? Are we alone? What is consciousness, and can we create it?

Right now, you are orbiting a black hole. The Earth goes around the Sun, and the Sun goes around the centre of the Milky Way: a supermassive black hole—the strangest and most misunderstood phenomenon in the galaxy. In A Brief History of Black Holes, University of Oxford astrophysicist Dr Becky Smethurst charts the scientific breakthroughs that have uncovered the weird and wonderful world of black holes, from Hawking radiation to the iconic first photographs of a black hole in 2019.

As technological advances and the creation of flying aircraft became realities, the sighting of UFOs increased, as did the interest in potential contact with aliens. It would hardly be groundbreaking for scientists in the 20th century to have a lunchtime discussion in which the search for extraterrestrial life arises, and the question of where it might reside is innocuous enough. However, a furor was created somewhat innocently when physicist Enrico Fermi voiced his “casual lunchtime remark” in the presence of colleagues in 1950.

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.

There was a time when “universe” meant all there is. Everything. Yet, in recent years discoveries in physics and cosmology have led a number of scientists to conclude that our universe may be one among many. With crystal-clear prose and inspired use of analogy, Brian Greene shows how a range of different “multiverse” proposals emerges from theories developed to explain the most refined observations of both subatomic particles and the dark depths of space.

Until the End of Time is Brian Greene's breathtaking new exploration of the cosmos and our quest to find meaning in the face of this vast expanse. Greene takes us on a journey from the big bang to the end of time, exploring how lasting structures formed, how life and mind emerged, and how we grapple with our existence through narrative, myth, religion, creative expression, science, the quest for truth, and a deep longing for the eternal.

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?

The Ape That Understood the Universe is the story of the strangest animal in the world: the human animal. It opens with a question: How would an alien scientist view our species? What would it make of our sex differences, our sexual behavior, our child-rearing patterns, our moral codes, our religions, our languages, and science? The book tackles these issues by drawing on ideas from two major schools of thought: evolutionary psychology and cultural evolutionary theory.

Free speech is the bedrock of all our liberties, and yet in recent years, it has come to be mistrusted. A new form of social justice activism, which perceives language as potentially violent, has prompted a national debate on where the limitations of acceptable speech should be drawn. Governments throughout Europe have enacted 'hate speech' legislation to curb the dissemination of objectionable ideas, Silicon Valley tech giants are collaborating to ensure that they control the limitations of public discourse, and campaigners in the US are calling for revisions to the First Amendment.

John Boyd may be the most remarkable unsung hero in all of American military history. Some remember him as the greatest US fighter pilot ever - the man who, in simulated air-to-air combat, defeated every challenger in less than 40 seconds. Some recall him as the father of our country's most legendary fighter aircraft - the F-15 and F-16. Still, others think of Boyd as the most influential military theorist since Sun Tzu. They know only half the story.

This urgent and eye-opening book makes the case that protecting humanity's future is the central challenge of our time. If all goes well, human history is just beginning. Our species could survive for billions of years - enough time to end disease, poverty, and injustice, and to flourish in ways unimaginable today. But this vast future is at risk. With the advent of nuclear weapons, humanity entered a new age, where we face existential catastrophes - those from which we could never come back.

Until the End of Time is Brian Greene's breathtaking new exploration of the cosmos and our quest to find meaning in the face of this vast expanse. Greene takes us on a journey from the big bang to the end of time, exploring how lasting structures formed, how life and mind emerged, and how we grapple with our existence through narrative, myth, religion, creative expression, science, the quest for truth, and a deep longing for the eternal.

The follow-up to his best-seller The War of Art, Turning Pro navigates the passage from the amateur life to a professional practice.

If we all want love, why is there so much conflict in our most cherished relationships? To answer this question we must look into our evolutionary past, argues prominent psychologist David M. Buss. Based one of the largest studies of human mating ever undertaken, encompassing more than 10,000 people of all ages from 37 cultures worldwide, The Evolution of Desire is the first work to present a unified theory of human mating behavior.

In this smart and funny book, celebrated cartoonist Zach Weinersmith and noted researcher Dr. Kelly Weinersmith give us a snapshot of what's coming next - from robot swarms to nuclear fusion powered-toasters. By weaving their own research and interviews with the scientists who are making these advances happen, the Weinersmiths investigate why these technologies are needed, how they would work, and what is standing in their way.

Since taking over TED in the early 2000s, Chris Anderson has shown how carefully crafted short talks can be the key to unlocking empathy, stirring excitement, spreading knowledge, and promoting a shared dream. Done right, a talk can electrify a room and transform an audience's worldview. Done right, a talk is more powerful than anything in written form.

As high achievers, we’ve been conditioned to believe that the path to success is paved with relentless work. That if we want to overachieve, we have to overexert, overthink, and overdo. That if we aren’t perpetually exhausted, we’re not doing enough. But lately, working hard is more exhausting than ever. And the more depleted we get, the more effort it takes to make progress. Stuck in an endless loop of “Zoom, eat, sleep, repeat”, we’re often working twice as hard to achieve half as much.

Everyone is curious about life in the Universe, UFOs and whether ET is out there. Over the course of his thirty-year career as an astrophysicist, Adam Frank has consistently been asked about the possibility of intelligent life in the universe. Are aliens real? Where are they? Why haven’t we found them? What happens if we do?

Writing from both the cutting edge of scientific discovery and the front-lines of elite athletic performance, National Magazine Award-winning science journalist Alex Hutchinson presents a revolutionary account of the dynamic and controversial new science of endurance.

Superintelligence asks the questions: What happens when machines surpass humans in general intelligence? Will artificial agents save or destroy us? Nick Bostrom lays the foundation for understanding the future of humanity and intelligent life. The human brain has some capabilities that the brains of other animals lack. It is to these distinctive capabilities that our species owes its dominant position. If machine brains surpassed human brains in general intelligence, then this new superintelligence could become extremely powerful - possibly beyond our control.

Jonathan Haidt skillfully combines two genres-philosophical wisdom and scientific research-delighting the listener with surprising insights. He explains, for example, why we have such difficulty controlling ourselves and sticking to our plans; why no achievement brings lasting happiness, yet a few changes in your life can have profound effects, and why even confirmed atheists experience spiritual elevation.
