Videographer SecureTeam10 published an extremely interesting video, showing from NASA's own footage an apparent attempt to cover up or hide "something," which appears to be an entrace or hole, at the North Pole.
The question of what are they hiding -Why are they hiding it, and last but not least, an entrance to what ... are questions we have seen over the course of decades as the videographer details, at length, along with past footage and images captured showing a "hole" or entrance, always in the same place, never moving nor changing size, bringing about the theory of a Hollow Earth.
(Nazi map purporting to show secret passages or "entrances" to Inner Earth)
The Hollow Earth theory proposes that the planet Earth either is entirely hollow or otherwise contains a substantial interior space.
As is pointed out at the website Ancient Code, in a piece titled "The Hollow Earth maps of the Third Reich: There is an entrance to the Hollow Earth", throughout history going back to ancient times, multiple civilizations have referred to what many still believe is the Inner Earth:
The Babylonian hero Gilgamesh visited his ancestor Utnapishtim in the bowels of the earth; in Greek mythology, Orpheus tries to rescue Eurydice from the underground hell; it was said that the Pharaohs of Egypt communicated with the underworld, which could be accessed via secret tunnels hidden in the pyramids; and Buddhists believed (and still believe) that millions of people live in Agharta, an underground paradise ruled by the king of the world.
What is not theory is the over-abundance of visual evidence that there are "entrances" or unexplained "holes" at the top of both the North Pole and the South Pole, with significantly more visual images regarding the ones at the North Pole being available, some of which are shown by Secure Team 10 in their May 20th video, and some shown below:
Whether one believes in the Hollow Earth theory or not, there is definitely "something" being hidden by NASA, something that governments refuse to offer any official explanation for, found in countless images from NASA itself and satellite images, referred to by multiple people throughout history and now again, SecureTeam10 claims that NASA has been caught red-handed attempting to hide information from the general public.
What are they hiding? What is down there that they don't want us to know about?
Note- Pay attention toward the end of the evideo to the images which appear to be pyramids.
Update - SQ Note - I COVER THIS EXTENSIVELY IN MY BOOK EMPIRE BENEATH THE ICE, AS EACH WEEK PASSES EXPECT MORE REVELATIONS ON' HOLES OVER THE POLES'.
