This is the full video that the OP clip mentions. IDK how long it will stay up on youtube, but it's been there over a year now, so settle back with some popcorn and enjoy the movie.
Says in this the caves are connected, mentions one in Iran and Israel. That's on the other side of the Earth. I'm sure if they meant that literally, it would mean the Earth underground isn't what we've been taught.
Wonder if there are connections beneath many important places. And also if these had anything to do with sounds recorded by NASA of Earth from space. No doubt, they inspired the Hollow Earth stories.
I've worked in executive suites of oil companies. In one company, they occupied the top floor of a modern high rise office building. There were a number of huge crystals, stunning in size and color. It was something I'll never forget seeing. Most of my specimens from picking out of crystal formations down the side of cliffs, rappeling, or visting caves with my geology field trips weren't large.
Later I spoke with a former miner about the crystals I'd seen at this energy CEO's offices. He spoke with awe in his voice, saying he'd had the 'privilege' of working in such mines and there were many things beyond the minerals and ores they were sent to take to the surface for commerce.
I'd love to get a DVD of this, but I've found some from the UK won't play on American players. Maybe they will on the computer, IDK.
Thanks for the thread leading me to this video.
