The Well-Planned Universe provides evidence-based insights into the nature of our world, ourselves, and the universe beyond. The book explains how recent developments in computer science along with evidence from physics, astronomy, chemistry, and biology reveal that there is more to the universe and ourselves than most people realize.

This series on time travel explores humanity's fascination with moving through time, blending science, fiction, and philosophy. It begins by introducing the concept of time travel, drawing from both historical myths and scientific theories like Einstein’s relativity. The journey continues through its portrayal in literature and film, from H.G. Wells to Hollywood blockbusters, before diving into the scientific possibilities of time travel, including wormholes and paradoxes. Ethical and philosophical dilemmas are also examined, alongside the profound cultural impact of time travel on our ...

Perché è importante andare su Marte? Perché la scoperta, l’avventura, la sfida sono insite nel destino dell’uomo, il viaggio è una costante dell’esperienza umana e la ricerca di altre forme di vita non è altro che una delle possibilità per avere dal futuro risposte sul passato. Scenderemo su Marte e diventeremo "marziani" per avere risposte, poiché anche la più straordinaria invenzione non potrà mai sostituire il fattore umano e l’atto di piantare fisicamente una bandiera.

On this ID the Future, Discovery Institute senior fellow Andrew McDiarmid explores the roots of the idea that our universe is just one of many universes, an idea stretching back to the ancient atomists and given new life in the modern era, first by physicist Hugh Everett. McDiarmid then looks at how the idea percolated into comic books and from there into popular culture. He caps off the episode with a reading of a recent article about the multiverse hypothesis by Stephen Meyer, author of the recent bestseller, Return of the God Hypothesis. Source

The Martians explores the CIA's top-secret search for the Martians, multiple photos of strange anomalies, and the latest revelations about the environment and water on Mars. And most tantalizing of all: Did an ailing Martian race come to Earth in past eons and were they confused with gods? The questions concerning life on Mars - then and now - are many. The answers are astounding.

Mercury, a lifeless victim of the Sun’s expanding power. Venus, once thought to be lush and fertile, now known to be trapped within a toxic and boiling atmosphere. Mars, the red planet, doomed by the loss of its atmosphere. Jupiter, twice the size of all the other planets combined, but insubstantial. Saturn, a stunning celestial beauty, the jewel of our Solar System. Uranus, the sideways planet and the first ice giant. Neptune, dark, cold and whipped by supersonic winds. Pluto, the dwarf planet, a frozen rock.

Given the fact that there are perhaps 400 billion stars in our galaxy alone and perhaps 400 billion galaxies in the universe, it stands to reason that somewhere out there, in the 14-billion-year-old cosmos, there is or once was a civilization at least as advanced as our own. The sheer enormity of the numbers almost demands that we accept the truth of this hypothesis. Why, then, have we encountered no evidence, no messages, no artifacts of these extraterrestrials?

Stick and Rudder is the first exact analysis of the art of flying ever attempted. It has been continuously in print for 33 years. It shows precisely what the pilot does when he flies, just how he does it, and why. Because the basics are largely unchanging, the book therefore is applicable to large airplanes and small, old airplanes and new, and is of interest not only to the learner but also to the accomplished pilot and to the instructor himself.

Since the beginning of human history Mars has been an alluring dream - the stuff of legends, gods, and mystery. The planet most like ours, it has still been thought impossible to reach, let alone explore and inhabit. Now with the advent of a revolutionary new plan, all this has changed. Leading space exploration authority Robert Zubrin has crafted a daring new blueprint, Mars Direct, presented here with engaging anecdotes. The Case for Mars is not a vision for the far future or one that will cost us impossible billions.

The Sun, Moon, and stars are crucial to your daily existence. The perfect regularity of the heavens is the only guaranteed part of life and inspires deep religious and philosophical ideas, while unexpected events such as eclipses and comets incite fear. Experience this ancient outlook with noted astrophysicist and historian of astronomy Professor Bradley Schaefer of Louisiana State University. An award-winning teacher, Dr. Schaefer takes you around the world, exploring the close relationship that people thousands of years ago had with the sky.

On a moonless night in January 1991, a dozen US aircraft appeared in the skies over Baghdad. To the Iraqi air defenses, the planes seemed to come from nowhere. Each aircraft was more than 60 feet in length and with a wingspan of 40 feet, yet its radar footprint was the size of a ball bearing. Here was the first extensive combat application of Stealth technology. And it was devastating.

Most historians study the smallest slivers of time, emphasizing specific dates, individuals, and documents. But what would it look like to study the whole of history, from the big bang through the present day - and even into the remote future? How would looking at the full span of time change the way we perceive the universe, the earth, and our very existence? These were the questions David Christian set out to answer when he created the field of "Big History", the most exciting new approach to understanding where we have been, where we are, and where we are going.

Mars was once similar to Earth, but today there are no rivers, no lakes, no oceans. Coated in red dust, the terrain is bewilderingly empty. And yet multiple spacecraft are circling Mars, on the brink, perhaps, of a staggering find, one that would inspire humankind as much as any discovery in the history of modern science. In this beautifully observed, deeply personal book, Georgetown scientist Sarah Stewart Johnson tells the story of how she and other researchers have scoured Mars for signs of life, transforming the planet from a distant point of light into a world of its own.

This third edition surveys the applicability of Egyptian cosmological concepts to our modern understanding of the nature of the universe, creation, science, and philosophy. Egyptian cosmology is humanistic, coherent, comprehensive, consistent, logical, analytical, and rational.

Spaceflight is notoriously dangerous. Beyond launch mishaps and equipment failures, astronauts face serious health problems from long-term weightlessness and high-energy radiation. Not to mention, the space environment is a near-perfect vacuum that can quickly kill anyone who is unprotected. Drawing on the hard-won insights of NASA astronauts and space researchers, this 12-lecture course presents the perils of spaceflight and what experts have done to make them survivable. It also deals with livability in space, including nutrition, sleep, environmental control, and personal hygiene.

Before John Glenn orbited the Earth or Neil Armstrong walked on the moon, a group of dedicated female mathematicians known as "human computers" used pencils, slide rules, and adding machines to calculate the numbers that would launch rockets and astronauts into space. Among these problem solvers were a group of exceptionally talented African American women, some of the brightest minds of their generation.

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?

A journey across time, from our most refined understanding of the universe's beginning, to the closest science can take us to the very end. Explore how life and mind emerged from the initial chaos and how our minds, in coming to understand their own impermanence, seek in different ways to give meaning to experience: in story, myth, religion, creative expression, science, the quest for truth and our longing for the timeless or eternal.

Travelling at almost 18,000 miles per hour - 10 times faster than a rifle bullet - Yuri Gagarin circles the globe in just 106 minutes. From his windows, he sees the Earth as nobody has before, crossing a sunset and a sunrise, crossing oceans and continents, witnessing its beauty and its fragility. While his launch begins in total secrecy, within hours of his landing, he has become a world celebrity - the first human to leave the planet. Beyond tells the thrilling story behind that epic flight on its 60th anniversary.

This playful, entertaining, and mind-bending introduction to modern physics briskly explains Einstein's general relativity, quantum mechanics, elementary particles, gravity, black holes, the complex architecture of the Universe, and the role humans play in this weird and wonderful world. Carlo Rovelli, a renowned theoretical physicist, is a delightfully poetic and philosophical scientific guide. He takes us to the frontiers of our knowledge: To the most minute reaches of the fabric of space, back to the origins of the cosmos, and into the workings of our minds.
