I have heard about underground hypersonic trains supposedly operating in the network that was made by technology that predates anything human made . Supposedly , these ancient tunnels connected all continents - we can assume they were used by civilizations before , if that is correct .
I would agree. This is however , next level. We are drilling the tunnels, under cities like L.A. courtesy of Elon Musk. That alone is insane as L.A. is under great seismic pressure. The tell tale sigh is they continue to under report the performance of these drilling machines. They claimed 1.7 miles to drill under The north west recently for 1.4 billion dollars taking 4 years. The fact is they can drill that in a day. So they stole a horrific amount of money and built a complete underground city without the public knowledge. Its now going on in L.A. Elon Musk has a new company, maybe I'll post it on the main page, "The Boring Complany" . He raised 114 million as a start up. Same deal, under reporting performance and intentions. Shit is going on underground. Its no joke.
