For one thing, there is no physical fire in Hell because it is not a physical realm. So this is a question for physics as much as it is a question for theology.
What does it really mean to “burn” in hell?
First of all, we should consider what damns a person in the first place? Cruelty, hatred, avarice, revenge, adultery, deceit, hypocrisy and impiety can all do us in. These “evils” are all derived from the love of self.
Everything an individual thinks and does is ruled by their intentions – that is what one ultimately seeks and loves. We often describe a person’s excitement as getting all fired-up. Perhaps hell is a realm where an evil person is consumed by the “flames” of his or her own self-love.
Anger is often described as a “smoldering” from within. It usually is ignited by some frustration, whereby something important to us is thwarted or foiled. Those with evil leanings often smolder when others do not do their bidding and promote their personal goals and self-interests. Inwardly, such individuals harbor a burning hatred for others.
Therefore, hell would be a “place” where evil souls go and are eternally frustrated by not being able to dominate over others or hurt others. Does not such a punishment fit the crime? How would justice be better served?
The idea that God would burn people in a culinary fire, and miraculously keep them alive to have their flesh cooked to an eternity is barbaric, and, contradicts the idea that God is Infinite Love and Infinite Wisdom.
Even on earth, we mortals have the sense to create a system of justice whereby the punishment fits the crime. Is God less rational and fair than we are?
Goodness is its own reward and evil is its own punishment.
Heaven and Hell are psychoscapes. That is, not existing in time or space, they are reflections of the qualities of our hearts and minds. The Lord’s heavenly kingdom is a kingdom of mutual love. Those who put themselves first cannot endure such a realm and seek to remove themselves from God’s influence, where they can worship themselves.
Such individuals are eternally thwarted by the self-interests of others, who also constantly seek their own prominence in all things. In such an infernal society, happiness can never be attained. This is what is meant by, “burning in hell.”
Does this make sense to you?
