Researcher reports large quantities of the substance under ruins of Teotihuacan in discovery that could shed light on city’s mysterious origins. The liquid mercury was discovered at the end of a tunnel beneath a Mexican pyramid. There is speculation that at the end of this tunnel ancient alien artifacts can be found in a secret chamber. Robots were investigating the tunnels beneath these ancient pyramids. The real question is what purpose this liquid mercury had on this special location. One theory claims that the shimmering, reflective qualities of liquid mercury may have resembled “an underworld river, not that different from the river Styx,” Headrick said, “if only in the concept that it’s the entrance to the supernatural world and the entrance to the underworld.” BTS Prolog by Kevin MacLeod is licensed under a Creative Commons Attribution license (https://creativecommons.org/licenses/...)
