Here is a thread to post finds of ancient technologies, ideas, architecture, etc. Preferably spiritual or hidden uncommon knowledge
. Though if something is just damn interesting please share!
Articles, Videos, Pictures, etc all welcome! Please try to use credible sources and if your not sure of the credibility try to state so. Rumours not welcome but theory invited!
I'll kick it off with an interesting youtube clip about how the great pyramids of Egypt correlate to constellations.
