Where, in the opinion of various religious leaders and their followers is Heaven or Paradise situated?

This is described in The Discovery of Heaven by Harry Mulisch. Max Delius is an astronomer who, after many experiments and calculations, discovers "another, timeless world...therefore larger than the universe". After the exhilaration of his discovery he is fatally struck down by a meteorite.

Perhaps Superstring Theory offers some clues. M-Theory supposes that there are eleven dimensions, of which seven "other" dimensions interact with our own "known" four dimensions of space and time. Jesus mentions to his disciples that the kingdom of Heaven is "near you" but yet invisible, beyond our comprehension and our ability to travel there without Him to lead us. Perhaps we can speculate that Heaven is one or more of the "other" dimensions suggested by Superstring Theory.

The location of Heaven is as yet unaccounted for, but some readers will remember that Hell was discovered under Siberia in 1991. The myth, reported as fact in several Scandinavian and American newsletters, and by Christian broadcasters such as Trinity Radio in Southern California, held that a geological survey in Siberia, drilling to a depth of 14 kilometres, had punctured the roof of Hell.

Many versions quote a Dr Azzacove as stating: "The drill suddenly began to rotate wildly, indicating that we had reached a large empty pocket or cavern. Temperature sensors showed a dramatic increase in heat to 2,000 degrees Fahrenheit. We lowered a microphone, designed to detect the sounds of plate movements down the shaft. But instead of plate movements we heard a human voice screaming in pain.

"At first we thought the sound was coming from our own equipment, but when we made adjustments our worst suspicions were confirmed. The screams weren't those of a single human, they were the screams of millions."
