Where are heaven and hell?

Answer 1

If they exist they would most likely be in another dimension of some kind or in another universe or galaxy trillions of light-years away. Neither exists where they are supposed to, so assuming they exist I think my hypothesis makes about as much sense as any.

//It is understood from The Bible that hell is a real place which is most likely inside the earth where the fire burns continuously. Heaven is a little harder to pinpoint.

Catholic AnswerHeaven and hell are more states of being, then actual places, although, of course, they are places too; but not as we understand them here on earth. Primarily heaven is union with God, it is enjoying the Beatific Vision; to some extent, we are in heaven here on earth to the extent that we conform ourselves to God's Will. Hell is the state of being permanently alienated from God, it is a state that we build ourselves while alive on earth, to which we are permanently exiled when we die. It is more important to understand that state then worry about the place; mostly because we cannot completely access either place while we are alive in this body, and most importantly, when we find out, we don't want to be in the state alienated from God for all eternity: as union with God is what we were created for.

Answer 2

How can we know? When the notion of heaven and hell was being developed, they were assumed to be physical places, with hell down below and heaven just above the sky. Science has shown that heaven and hell can not be located in any physical location in the universe. Religion has therefore adapted by saying that heaven and hell are not actually physical places, but spiritual states of being. Even if they exist, they are nowhere.
