Deadly forest. Haunted houses. Mountains where visitors never return alive. Are there such things as "evil places"? Places where bad things seem to repeatedly -- and inexplicably -- happen? And if so, is it possible that these locations are imbued with dark energy that is currently beyond our understanding?

For centuries, archaeologists have tried to unravel the mysteries of how – and why – certain incredible structures like the Great Pyramid at Giza, the staircase at Loretto Chapel, and Coral Castle were built. Will we ever find the answers? Or, might these structures have been intentionally constructed to perpetually mystify us?

Millions of people around the world claim to have had an encounter with a creature unlike any recognized by mainstream science – such as the Mothman, Chupacabra, and Mongolian Death Worm. Could these incredible creatures be real? And if so, what could possibly explain these freaks of nature?

Many mysteries of planet Earth are far from understood. How was Devil’s Tower formed? Or why do some people get struck by lightning multiple times?

Perhaps the greatest unexplained mystery of all is: what happens to us after we die? Perhaps clues to the answer lie in unusual cases of near-death experience, reincarnation, and how memories can be passed from organ donors to transplant recipients. Are these phenomena figments of our collective imagination, or could they be real?

Even after centuries of study, the human mind remains as inscrutable as ever. Could the quintessential human machine, the brain, be even more powerful than we realize? And does that suggest that fantastic abilities such as Remote Viewing will one day be recognized not as science fiction, but as science fact--even if, for the moment, they remain UnXplained?

How do some people live through the impossible? Whether it's plane crashes, bearing freezing temperatures, or performing superhuman feats while in danger ? remarkable tales of human survival force us to reconsider what we know about our own will to live.

Some of history's greatest tales are stories of escape, the most incredible of which defy explanation. How did Harry Houdini pull off his daring feats? Was the "Escape from Alcatraz" in fact, successful? And what about the mysterious guidance one man received that allowed him to escape the South Tower of the World Trade Center on 9/11? Are there strange forces these escapees draw upon to beat the odds, where so many others fail? Or, like a great magic trick, will the secrets of how they cheated captivity remain UnXplained?

Our five senses--sight, smell, hearing, taste, and touch--construct the reality of the world around us, like a blank canvas continuously painted and repainted over every day. For each person, this portrait of reality is slightly different, but we more or less agree that the sky is blue, lemons are sour, and horns are loud. But what about when one or more of your senses is heightened, changed, or even taken away all together? Do people with these radically-altered senses show us that each of us has limitless sensory potential, waiting to be unlocked? And is it possible that we have a mysterious "6th sense," one that is currently UnXplained?

Throughout history, many have believed that certain places, things, or even people can be tainted with dark curses. Ominous lakes that morph into watery graves.

For decades, the debate has raged as to what exactly Unidentified Flying Objects--or "UFOs"--really are. Theories have been put forth that attribute them to everything from secret military aircraft to weather phenomena and more. But by far, the most controversial theory is that these objects are, in fact, spacecraft that have been piloted to Earth by extraterrestrial beings. It's a seemingly outlandish notion, but could it be true? And if so, how much does the government know about these spacecraft--and the aliens who are visiting our planet?

Despite all of our modern technology and sophistication, there is much that we still don't know about what lies beneath our feet, deep underground. What is at the center of the Earth? Is there really a solid core of heavy metals, or could it be a hollow environment, as many researchers claim? And just how much of mankind's history took place underground? Recent discoveries of ancient underground structures such as the city of Derinkuyu and the Malta Hypogeum suggest that there may be more structures down there, waiting to be re-discovered. If much of our past was subterranean, could our future be as well?

Stories of those who lead double lives are both daring and baffling. What compels a person to attempt to become someone else? Is it merely for material gain, to pull off an ingenious scam? Or is there a deeper reason? At one time or another, we've all fantasized about trying on a new identity, but when does the line between impersonation and transformation get blurred? Is it possible that by pretending to be someone else, a person can actually become that person, at least in their mind?

Many see them as massive testaments to America's progress. Some view them as immutable symbols of the human spirit. Others perceive them as sacred shrines dedicated to the ideals of liberty and freedom. But no matter what they represent--America's monuments are inarguably impressive due to their colossal size and scope, their groundbreaking feats of engineering, and their storied histories. Why is it that America's greatest monuments continue to enthrall us decades--and sometimes centuries--after their creation? And perhaps more importantly, what closely guarded secrets may their implacable facades be hiding?

According to the Greek philosopher Plato, the lost continent of Atlantis was once home to an advanced civilization before it was destroyed in a cataclysm. But was Plato's story merely a myth?

Will Atlantis finally be re-discovered, perhaps by employing modern technology? Or will this lost civilization remain...UnXplained?

For centuries, humanity has been compelled to build remarkable structures that are much more than simple places of shelter or work. What makes us want to create magnificent buildings that are bigger and grander than ourselves--and last for centuries? Whether it's Stonehenge, the Notre Dame Cathedral, or the world's tallest skyscrapers--extraordinary works of engineering are evidence of a strong instinct within us that we don't fully understand. Are we trying to prove something? Or perhaps show our power over nature? Or could there be another reason that is, for now...UnXplained?

Gold. It's one of the most valuable precious metals on the planet, has been coveted by societies for centuries, and can be found inside countless modern electronics.
