I have seen references to this story several times, and just recently, my sister mentioned it, believing that it was based on a real event in the 1980s, in Russia.
The story is retold on Youtube like this:
As some may recall, there were lots of wild stories floating around back then, about dramatic things happening in Russia, like "real witches", UFO landings and extreme natural phenomena, but all were based on hearsay.This fits that criteria, but the story is still alive today, and seems to be known in the English speaking world too. But this story is so old now that surely if this digging actually took place, people would know about it?
According to the version my sister heard, this happened somewhere on the Kola peninsula, not far from the the Finnish border. All the scientists became believers after hearing the sounds and one of them walked across the border to Finland and told his story to some Finnish Christians who passed it on.
Personally I believe that if hell exists, it would not be a physical place that we can see or listen to in this world.
Hoax or real, has there been such a hole and recording, and is this story known in Russia?
