In my opinion Jesus talked as much about heaven, as about hell in Mark 9:46. The termodynamic state he relates to hell, eternal energy, is the opposite to the direction our universe constantly seeks. The universe constantly seeks its lowest energy states, which ultimately means Eu -> 0. The creator of this universe is very determined to go the other direction, away from a termodynamic state in which the flames never dies. I belive Jesus was ahead of his time which I have described on youtube (see link) and here: http://headbiotech.wordpress.com/.
