The U.S. Bullion Depository, better known as Fort Knox, is home of the United States Army and one of the world's most top secret fortresses. Hidden deep inside the vault is an estimated $73 billion dollars in gold. Almost all information about it is classified. Through interviews with eyewitnesses, rare photos and rarely seen films, we will construct a picture of what the building might look like. Hear testimony of those journalists and congressmen who were among the select few invited inside in 1974. Discover the history and secrets behind the Army's tank warfare and the classified military technologies it will use to fight the wars of the future.

It is a fireball in the sky, a bubbling, boiling, kinetic sphere of white hot plasma, exploding and erupting. Its size is almost unimaginable--one million Earths would fit within its boundaries. In this violence is born almost all the energy that makes existence on Earth possible, yet, its full mysteries are only now beginning to be understood. From Sun spots to solar eclipses, solar flares to solar storms, the birth of the sun to its potential death, discover the science and history behind this celestial object that makes life on Earth exist.

Hitch a ride on the journey of a comet as it roars from the cold, dark outer reaches of the solar system to the fiery surface of the Sun. Visit the surface of each planet, from the mountains on the moons of Neptune, to the caves beneath Mars, to a solar tsunami. You'll also tour the lesser-known "neighborhoods" of the Solar System, like The Oort Cloud and planet-sized asteroids like Eris and Ceres. Witness the punishing extremes experienced by a massive, grit-covered snow-ball as it travels 300 million miles from the edge of the Solar System to the skies above earth.

In this episode, our cast uses awesome analogies to bring the biggest objects, farthest distances and fastest speeds down to earth. To truly understand the scale of the cosmos, we jump behind the wheel of monster trucks, scale the Golden Gate bridge, and race across the desert in a rocket-powered car.

Within our immense universe lies a lesser-known world of tiny particles. From strange ghostly neutrinos that pass right through matter to mysterious objects with names like MACHOs and WIMPs. Find out how this miniature world might hold the key to understanding the cosmos.

The Battle of the Little Big Horn is one of the most iconic events in American history. It is an amazing story, but until now it has never been fully told. Many questions still remain but one question remains above all the others, did any of Custer's soldiers survive? New evidence suggests that a soldier named August Finkle was the lone survivor of "Custer's Last Stand," a battle that is practically synonymous with "no survivors." His tale of what actually went on in the battle may revise our interpretation of the events of the day.

Megalithic monuments linked together by electromagnetic energy... Prehistoric ruins arranged across vast distances in straight lines... And advanced mathematics carved into landmarks more than 5000 years ago. Were ancient man's spectacular structures built by humans alone? Or do they bear evidence of being designed--and interconnected--by otherworldly visitors?

Why were ancient civilizations around the world so focused on the Orion constellation? While scientists site many earthly connections, researchers suggest this point in the night sky may have been a so-called Stargate, or entry point, for alien life forms. If extraterrestrials have been visiting Earth for thousands of years, might they have originated from the Orion Nebula?

Geologist Scott Wolter visits a Minnesota farmer who wants to investigate the possible existence of bones from a giant he unearthed in his yard. The bones raise the question of whether Vikings could have traveled all the way to America.

Scott Wolter investigates the mysterious disappearance of vast amounts of copper from Lake Superior. Through scientific testing a connection is made to a pre-historic civilization and the Bronze Age.

Rennes le Ch teau is a small village in the Pyr n es of Southern France. It's a quiet place until tourists arrive hunting its secrets. According to legend, the Knights Templar brought the Holy Grail here for safekeeping. Those who come on pilgrimage think the Grail is very different than history records.
