Might the tools and technology of ancient builders have come from distant galaxies? Evidence suggests that an ancient mountaintop fortress in Peru was constructed with laser-like tools... temples at Vijayanagara India were built to harness cosmic energy... and an acoustic chamber in Malta enabled interplanetary communication.

Unearthly visitations... Heavenly messengers... Close encounters... Accounts of humans interacting with celestial beings have existed since the beginning of mankind. Many of these encounters resulted in moral, philosophical and artistic inspirations. But did these contacts involve ethereal beings from heaven or extraterrestrials from other worlds? Are holy books the word of God, or guidebooks passed down by more advanced civilizations? Who told Joan of Arc how to defeat the English Army--saints or extraterrestrials? Could a young boy from India have learned advanced mathematical formulas from a Hindu goddess? What message did an American serviceman receive while touching an alien aircraft? If the Ancient astronaut theory is correct, then are beings from other worlds communicating with us for our benefit... or theirs? Just what is the purpose of these alien contacts?

Albert Einstein's revolutionary theory that turned the world upside down might have been dismissed but for a math mistake, a cloudy sky, and the start of World War I. This fascinating two-hour special tells the story of Einstein's little-known, 15-year struggle to prove one of his most radical theories -- a theory that upended Newton and three centuries of scientific thought and called into question the definitions of space and light and gravity -- the game-changing concept known as the Theory of General Relativity. Today, more than a century since the "Miracle Year" in which he published many of his breakthrough papers, Einstein's ideas remain a living, vibrant influence. They continue to push scientists farther, and deeper, into the universe than even he could have imagined. TVPG VL | CC

A man shows up at Scott Wolter's lab with a 500-pound discovery. In the flatbed of his truck is a large boulder he pulled from the Arkansas River, inscribed with a mysterious bull symbol. Wolter's investigation into who carved the stone and for what ritualistic purpose ultimately reveals a connection between the ancient Egyptian cult of the Apis bull, the mysterious religion known as Mithraism and a party of pre-Columbian explorers to Oklahoma's panhandle. In the end, carvings in a cave in America's Heartland shed light on an ancient connection that could prove a group of religious outcasts made it to America in pre-Columbian times.

With the naked eye we can't see the things that are too fast or too slow, too big or too small...until now. In this fascinating documentary, we count down the 40 most amazing things you can't see with the human eye. We use the latest in cutting edge technology, and state of the art CGI animation to reveal the astonishing reality of the invisible world around us. TVPG VL | CC
