guy Posted June 29, 2021 Report Share Posted June 29, 2021 (edited) Another interesting article on this fascinating site: Quote ” The ancient city of Hierapolis has long hidden a poisonous secret in its mysterious "Gate to Hell". But modern science has finally uncovered the truth behind the Roman myths.“ Quote “But Pfanz was still mystified by one thing: if this area is so deadly, why did the priests in the Ploutonion not die too? "But because carbon dioxide is heavier than air, at night when it's cooler it pools in the arena, creating a lethal lake of gas at ground level." His conclusion: the animals, with their noses close to the ground, quickly suffocated in this toxic cloud, but the priests, standing taller, were breathing much lower levels of CO2 and were able to survive.” https://www.bbc.com/travel/article/20210629-turkeys-mysterious-portal-to-the-underworld A previous post: Interesting video on the site: Edited October 11, 2021 by guy Quote Link to comment Share on other sites More sharing options...
