This week on Unknowable we wanted to investigate what astronauts think of life beyond our planet. There are only 536 people who have been into space and we thought they seemed uniquely qualified to answer the question: are we alone in the universe? And, maybe more importantly: what kind of weird shit have you seen out there in the vast darkness of the void?

This week we talk about the yet-to-be-solved case of The Zodiac Killer. He murdered a confirmed 5 people in northern California from 1968-1969 and sent numerous letters to local police stations and newspapers, including many mysterious ciphers (only one of which has been cracked to this day). Was it one man who committed all these crimes, or several unconnected murders that only became linked when a separate entity started sending the letters? Did he kill 5 people or the 37 he claimed? WHO is the Zodiac?

This week's episode focuses on some lesser-known cryptids. Gray tells us about The Fresno Nightcrawlers (also more aptly named The Fresno Nightwalkers), some very fabulous and stylish cryptids who strut around the Western United States. Justine tells us about The Beast of Bray Road, Wisconsin's own man-beast that stalks the fields in and near Elkhorn. 

This week's episode of Unknowable explores our very own creepy New England! We talk about The Bennington Triangle, an area of rural Vermont that seems to have a penchant for unusual flashing lights, cryptid sightings, UFOs flying overhead, and missing people galore...

Episode 17 brings two very different, but equally strange, topics. Polybius is a video game that popped up in just a handful of arcades in the 80's before swiftly disappearing... was it used as some kind of mind control device? The Taos Hum -- more generally called The Hum, as it exists all over the world -- is a low-frequency rumbling, whirring, or buzzing that people called "hearers" experience. Is it a result of secret government experiments or equipment? Is it a bizarre natural phenomenon? Or is it all in their heads?

This episode is about the snowy mystery of what the heck happened to a group of nine hikers in the mountains of Russia. The theories are ENDLESS - were they attacked by a Yeti? Did gravity experience a little snafu? Was it a simple avalanche? Are there secret military tests being covered up? Give this episode a listen to hear our thoughts!

This episode is all about the man, the mystery, the legend: D.B. Cooper. The only person to ever commit air piracy and never be caught. He hijacked a Boeing 727 aircraft in the Pacific Northwest, acquired a ransom of $200,000, parachuted out... and has never been seen or heard from again. Is he dead? Is he in hiding? Did he do it for the money or for the thrill? Give this episode a listen and hear our theories...

This episode of Unknowable is about maybe the two most memorable deaths in the hip hop world: the assassinations of Tupac and The Notorious B.I.G. To this day, it is unknown who killed either of them. Were their murders connected? Was it a result of an East Coast/West Coast rivalry? Was it gang retaliation? Or is Tupac still alive somewhere, listening to this episode...

This episode of Unknowable is about one of the better known alien encounters in the United States, which took place in Kelly, Kentucky! 12 people in a farmhouse were terrorized for hours by what they were convinced were alien beings -- under 3 feet tall, clawed hands, large glowing yellow eyes, and a strange gait that could only be described as floating. Were these aliens, goblins, gremlins, or...

For episode 12 we've decided to delve into a couple of topics that are a bit more conceptual than cryptids and aliens -- folie à deux (French for "madness of two") and "the call of the void" (also known as the High Place Phenomenon). Two psychological concepts that have never quite been pinned down, but make our brain do some pretty frightening things...
