Across borders, cultures and time, food is one thing that all people share. And from the time of the caveman to today's spaceman we like our food to go. While the burger and fries reign supreme in the world of fast food, grub on the go has taken us way past the drive-thru. Quick eats like beef jerky have allowed us to explore new frontiers and pocket-sized portables like protein bars enable us to push our bodies to the limit, no matter the conditions. Fueled by pizza, we have burned the midnight oil, and from the battleground (MREs) to the final frontier (space food,) food is always along for the ride. This is the countdown of fast foods that takes us back, propels us forward, and sometimes even gazes into the future (the fortune cookie.) TVPG VL | CC

When Scott Wolter began investigating mysterious artifacts, he started to notice one unique symbol appeared on many of them. The symbol, now known as the "Hooked X", baffled researchers who couldn't make sense of it. As Scott's investigation into the origins of the symbol unfolds, he realizes its use is unique to just two notoriously secret groups--the Knights Templar and their modern day brethren, the Freemasons. Used in secret codes, cryptic ciphers and even the alleged tomb of Jesus himself, the symbol could be the key to understanding two of the biggest mysteries of all time--exactly what the Holy Grail is, and where it's hidden today.

The Newport Tower is considered by many to be the most mysterious structure in the United States. Some people think it's a colonial era windmill or perhaps all that's left of an early water tower, but Scott Wolter is convinced it's something far more significant. Because of the archaeoastonomy and solstice illuminations that take place inside of the meticulously planned stone structure, he believes the Knights Templar came to America and built it centuries ago. Now, he's dead set on proving his theory. While planning an elaborate laser light show designed to illustrate the Tower's miraculous features, Scott discovers something else significant that ties this structure--and the Templar's modern day initiates--to one of America's most visited and most treasured icons.

It was one of the greatest cities ever depicted in biblical text. Hebrew prophets of the Bible all predicted its destruction--as many as 150 years before it happened. And, when in 539 BCE, Babylon fell to Cyrus the Great of Persia, the prophets were thought to have been proven correct. But scholars and academics have long debated the question of whether these ancient predictions were meant for the city of Babylon of more than 2,500 years ago, or whether they referred to a different Babylon, a future Babylon to be rebuilt where the old city once stood. Ancient Babylon is now known as modern-day Iraq, and eerily similar parallels exist between the prophecies of Babylon and the events of the late 20th and early 21st centuries--including both Gulf Wars and the downfall of Saddam Hussein. Is it possible that Biblical prophecies are playing out in modern times? TVPG VL | CC

Hern n Cort s stands as one of the great Conquistadores of all time, and among the most brutal. His thirst for gold and power led him to Mexico in 1519, beginning a conquest unlike any other in history. Remarkably, Cort s was under strict orders not to engage in any wars of conquest when he was sent to meet with the rulers of the Aztec empire--orders unheeded by Cort s. His first contact with the indigenous people resulted in a battle that so terrified them that they fled into the interior of Mexico. They had never seen the guns, horses, and shiny metal armor of the conquistadors. In approximately two years, Cort s owned the Aztec empire, and their once proud ruler Montezuma was dead. Through brilliant execution, from an often precarious military position, Cort s killed hundreds of thousands of Aztecs and brought down the 300-year-old empire--the first major American civilization to fall to the Spanish.

Known as El Cid (The Leader), the 11-century warrior Rodrigo D az liberated his fatherland from the Moors. Yet recent scholarship reveals many contradictions between reality and myth about Spain's first national hero. In one contemporary's words he was "the scourge of his time". Was he arrogant and insubordinate, a stern overlord driven by an unquenchable thirst for money? Before his death, he was already celebrated in a poem written in tribute of the conquest of Almer a; posthumously he was immortalized in the great epic Poema de M o Cid and was the centerpiece for countless other works of literature. Equally at home in the feudal kingdoms of northern Spain and the exotic Moorish-held lands of the south, when he died in Valencia in 1099, he was ruler of an independent principality that he had carved out of eastern Spain. Was Rodrigo a zealous Christian leader or a mercenary that sold his martial skills to Christian and Muslim alike? TVPG VL | CC

Scientists at the University of Kansas believe gamma ray bursts were responsible for a great mass extinction on Earth 450 million years ago. The gamma rays strip away the ozone layer and generate chemical smog, producing a widespread chill that grips the Earth. It would cause food chains to collapse resulting in a prolonged worldwide famine. Also, an expected electromagnetic pulse will zap all of our electronics. Scientists predict the Earth will be able to support only 5 to 10 percent of its current population; that means close to 6 billion people will die--most by starvation.

Analysis of video taken of an alleged UFO over Illinois suggests the object could have been as large as 1500 feet across. The video, featured on UFO HUNTERS, captured three bright lights in a triangular pattern. It was part of a mass sighting of over fifty reports near Tinley Park, Illinois in 2004. Upon investigating, the team discovered that similar objects were reported all over the world in the days surrounding this event--from Australia to Canada. Sightings of triangular-shaped UFOs have been on the rise in recent decades, but was the Tinley Park mass sighting a solid object, or as some believe, a hoax involving weather balloons and flares?

Gods and religion played an extremely important role in antiquity. The problem with so many religions being worshipped by the Greeks and Romans was how would the priests of these temples pay for their upkeep?

It was a heavy mix of religion and science. One of the most famous illusions was found in Alexandria at the temple of Serapis, where an iron chariot was suspended in mid air.

Before Lincoln finally came to rest in a steel-and-concrete-reinforced underground vault in Springfield, the President's body was repeatedly exhumed and moved, his coffin frequently opened. In 1876, eleven years after Abraham Lincoln's assassination, a band of Chicago counterfeiters plotted to steal Lincoln's body and hold it for ransom.
