My first thought is: Releasing all that heat from Hell is only going to speed up global warming.
My second thought is: Surely it’s hot inside the Earth anyway, upwards of thousands of degrees Celcius. Man I wish I had a non-shit Internet connection so I could easily find out the figures.
My third thought is: The interior of the Earth is in constant motion, and the high-gradient temperature and pressure difference introduced by drilling from the surface is only going to increase the unfamiliar sound at these depths. This sounds like it’s just an audio simulacrum.
My fourth thought is: You haven’t provided a source for this quote. Negrep for pubchat citation rigour.
