Why does the galaxy seem silent? Maybe aliens aren’t rare—maybe humans are. We explore the strange mix of traits that turned one clever primate into a technological civilization, and whether our oddities might be the real Great Filter.

They keep coming back. There are areas around the world that seem to keep attracting UFOs. Objects that return to the skies overhead across the course of years and decades as if taunting the witnesses below. These eyewitnesses don’t need convincing that something may be out there, because they’ve seen it with their own eyes. From incredible crop circles, to bizarre recurring lights over Norway, to vacation spots on the Pacific Ocean buzzing with UFO’s. All have been a draw for the most mysterious of phenomena. The question is: why?
These are the witnesses that have been literally touched by the unknown. Physical contact events that take the shape of nightmares, complete with alien examinations…inexplicable metal implants discovered inside human bodies…lives are changed by this physical brush with our greatest mystery. These eyewitnesses feel chosen, for something they likely never wished for. Do these cases hold the answer to the central questions of UFOlogy: what do these visitors want from us? Are we merely test bodies in what, from space, might be seen as a giant Petrie dish?

Set out on a Navy training mission with a squadron leader who swears he and his colleagues have seen the same UFOs pop up on their radar day after day. See if science can prove that these fast, agile crafts are real and not just an illusion.

A Hawaiian volcano called Kilauea is one of the most active in the world. After years of constant lava activity, see how a sudden collapse of the crater floor and a massive eruption drains it of lava, making the volcano possible to explore.
