The Why Files - 4 ª Season

(Including God) Is this reality? Well, we're experiencing ... something right now so maybe the better question is: what is reality? Could everything we see, everything we experience, everything that exists in our entire universe -- be artificial? Supporters of Simulation Theory believe that not only is it possible that we're living in a simulation; it's likely. And the more we look for evidence, the more we find. Philip K Dick believed deja vu was the simulation adjusting to new code. Many people experience The Mandela Effect, a or "false memory" shared by a large number of people. But the biggest clues of Simulation Theory come from science. Specifically: quantum mechanics. The only way the Double-Slit Experiment makes sense is if we live in a program. Quantum Entanglement also defies logic. Only our program would have the ability to defy the laws of physics - and the concept of time. Let's find out why.

When the drill reached 14.4 kilometers, it had broken through solid rock and into a large cavern that wasn't supposed to be there. From the surface, scientists could hear something coming from the hole. They lowered down an instrument array including a microphone. There was air in the cavern nine miles beneath the surface, but it was mostly toxic gas and the air temperature was over a thousand degrees. None of this made sense. They turned on the microphone. What they heard caused most of the crew to quit on the spot. For the few that remained, it only got worse. They called it the well to hell.

MYSTERY OF THE CIRCLEVILLE LETTERS. We all keep secrets. For most of us, these are nothing more than minor embarrassing details about ourselves. But some of us have dark secrets which, if discovered, could destroy lives. For years, the residents of Circleville, Ohio, received bizarre, threatening letters; from someone who somehow knew every salacious detail of their personal lives. The letters cost people their jobs, their marriages, their freedom, and sometimes, their lives. Over a thousand letters were sent over *20 years*. Yet somehow, whoever wrote them got away with it. Or did they? Officially this case is closed. But for decades, many people felt that the real culprit is still at large. Let's find out why.

Admiral Richard Byrd leads Operation Highjump, a 1946 naval mission to Antarctica ostensibly for scientific research but with secret goals of extending American sovereignty and finding a rumored Nazi base with new flying saucer technology.

A man arrives at a Tokyo airport with a genuine passport, but it's from a non-existent country. Authorities are baffled by his origins, wondering if he's a visitor from a parallel universe or an alternate reality.
