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.

So you’ve fallen in love with space and now you want to see it for yourself, huh? You want to witness the birth of a star, or visit the black hole at the center of our galaxy? You want to know if there are aliens out there, or how to travel through a wormhole? You want the wonders of the universe revealed before your very eyes? Well stop, because all that will probably kill you.

The fate of the Lost Ark of the Covenant is one of the great historical mysteries of all time. The Bible contains hundreds of references to the Ark's power, but the Ark itself mysteriously disappears from recorded history sometime after the building of the Temple of Solomon.

This intrepid journalist has tracked down the true story behind the myths and legends - revealing where the Ark is today, how it got there, and why it remains hidden.

Every year, 200 experts across machine learning, automation, robotics, and space arrive in Palm Springs for MARS to share new ideas about how these four fields will shape our future. TV host and maker of things Adam Savage (MythBusters) takes listeners deep inside the MARS conference. In interviews with more than a dozen leading scientists and thinkers, Savage explores the mind-blowing and often misunderstood ways in which science and innovation are transforming the way we live, work, and play.

There are deep connections between stars and atoms, between the cosmos and the microworld. Just six numbers, imprinted in the "Big Bang", determine the essential features of our entire physical world. Moreover, cosmic evolution is astonishingly sensitive to the values of these numbers. If any one of them were "untuned", there could be no stars and no life. This realization offers a radically new perspective on our universe, our place in it, and the nature of physical laws.

On a cold January morning in 1986, NASA launched the Space Shuttle Challenger, despite warnings against doing so by many individuals including Allan McDonald.

In Truth, Lies, and O-Rings, McDonald, a skilled engineer and executive, relives the tragedy from where he stood at Launch Control Center.

This fascinating new volume tells the story of contact between aliens and humans from all across the globe, dating back to 1932, including meetings with military personnel and American presidents such as Eisenhower and Kennedy. For the first time, a former member of MI6 reveals her conversation with Neil Armstrong at a NASA conference, when she confirmed that there were "other" spacecraft on the moon when Apollo 11 landed in 1969. Armstrong also confirmed that the CIA was behind the cover-up.

A Russian dissident, a Jesuit priest, and an American mule skinner are but a few of the bold visionaries who crafted the scientific story of cosmic origins. The collective insights of these and numerous creative thinkers advanced human understanding from mythology to mathematics, yielding falsifiable alternatives to ancient folklore and campfire tales. Listening to the Big Bang tells the dramatic human story—filled with colorful characters, unsung catalysts, and glorified heroes—which made the Big Bang the leading cosmological theory.

This new and long-awaited sequel to Carl Sagan's international best seller continues the electrifying journey through space and time, linking worlds within and worlds billions of miles away and envisioning a future of science tempered with wisdom. Based on National Geographic's internationally-renowned television series, this groundbreaking and visually stunning book explores how science and civilization grew up together.

With impressive examples von Däniken illustrates some of the numerous cities that were dug underground as safe harbors from the destructive boulders. Miles and miles of underground passageways have been discovered around the world as they made space for villages and entire cities. To end the book, von Däniken presents his newest discoveries of an event: In 2017, the author was informed that strange mummified creatures were found near the Peruvian village of Nazca. One of the mummies, apparently several thousand years ago, had been implanted with a metal plate under the skin.
