Schnieder went into depth about the technology used to build tunnels under the earth without having to excavate, so that no one on the surface would know.
Phil Schnieder, in case you didn’t remember, was a geologist who advised the government on the challenges it might face in constructing a subterranean base.
The process is straightforward: bedrocks are turned into lava, which is then used to create deep, smooth tunnels. This material is from decades back, so imagine how far we have come since then.
In essence, we may conclude that we have a whole secret universe right under our feet that we are completely unaware of, as well as its true meaning. Imagine a fully functioning city miles under your feet.
