According to Christianity, where are heaven and hell located?
It used to be believed (and is generally depicted) that hell was below ground and heaven is above the clouds (as in you assend to heaven much like a dove) and you go down to hell. The angels fly down from heaven with their wings. In many cathederals angels and heaven are depicted in the clouds.
Likewise hell is thought of as the underworld much like Hades of Greek mythology.
What is the general belief now that we know the Earth is a globe travelling through space. Do Christians still believe that hell is located underground. Maybe in a hollowed out area near the lava that makes up the center of the Earth?
Or alternatively is Heaven and hell located in a parallel dimension, sort of super-imposed on top of this one. In that case would Heaven be located in the clouds and Hell underground but we couldn't see it because it was in a parallel dimension? In other words that dead people could walk around the real world like ghosts but nobody could see them?
Or would they be in an entirely different Universe? If so, would Heaven and Hell be located both in the same Universe or separate Universe?
I suppose the last possibility is that Heaven and Hell are located completely in the imagination of an omnipotent being, much like a computer running a vast simulation.
For people who believe in heaven and hell, what can you say about their location?
