I assume this would be the right place to put this seeing as how I'm not asking if you believe in hell or not, I'm merely asking if you think it it's heated by things around it or if it heats itself. I'm going to say that it's exothermic. Heating caused by the extreme amounts of methane that has to be made by all the farting souls in hell. And I'm going to say that Satan is a smoker, so he first lit the place while lighting up one of his smokes, and the methane has simply either caught everything in hell on fire or is continuously being reflamed by the gaseous souls. Discuss.
