heaven and hell do exist, but do you think they are places?
Bodies take up space. In order for Christ to be a whole man, i.e. body AND soul, he must be in a place. The same holds for all men, eventually.
Exactly. Heaven and Hell must be actual physical locations, because they contain physical entities, i.e. our resurrected bodies. It intrigues me though, that in the New Testament Jesus is seen going up into Heaven only once, at the Ascension. On several other occasions, however, He suddenly appears (to the apostles in the Upper Room, for example) and disappears, (from the two disciples going to Emaus, to give another example) apparently without rising into Heaven and descending again to Earth. So where did He go? Where was He in between His appearances?
Regarding Hell being "down" under the surface of the Earth, there have been many stories of miners, spelunkers, and others who have reported hearing the screams of the damned when they ventured underground. I even saw a YouTube video (I think it was posted on this forum) with a recording made by a Soviet scientist of those same voices. In addition, Hell in the Old Testament is often referred to as the "pit," and at Fatima the three seers saw a pit open up below as the Virgin showed them souls falling into it "like snowflakes."
All of these speculations fascinate me because many physicists postulate and even seem to have quite a few proofs of the existence of unexplored dimensions and states of being and I have to wonder how Heaven and Hell might fit in with those findings. On the other hand, many ancient cultures believed that you could actually walk up to the entrance to Hell as to the mouth of a cave; Mt. Olympus where the Greek gods resided was an actual place and in Genesis the people built the Tower of Babel partly so that they could reach God. I really don't know what the Church specifically teaches on this.
