Maybe eternity is the instant before we really die. From the viewpoint of our own cognitive awareness this isnt too hard to believe. Since time and space are one and the same then maybe the eternity we endure before we really die is experienced as an endless expanse of space. But what are we? Fundamentally speaking, we are mass and since mass is energy then it is well possible that Hell can fit a lot of people and be able to continually burn them. I have not been drinking. I heard that in Hell people eat each other. Therefore your soul flesh (the flesh you wear when you are in Hell) probably grows back at a very fast rate, seeing as you would die if you lost all your flesh. This means that you can constantly be burned while not becoming numb to the fire because the new flesh regrowth would have new nerve endings.
