What is heaven? what is hell?

As far as Im aware Heaven has already been created, Adam and Eve flourished there at the start of creation.. but Hell, hell is yet to happen... its yet to be created, Hell is probably what Earth will become once consumed by the sun or hit by a massive meteor and knocked out of orbit..it could also be the core of the earth, miles into the Earths mantle..which is basically a "Magma Chamber" with molten Iron and Nickel with barely any oxygen and extremly high pressure or its probably not even physical place at all and could just be a manifestation of the mind.. full of nightmares, unrest and eternal guilt.
