This form of existence is both fascinating and horrifying. This is a form of existence which no one has experienced in This Life. This is a form of existence which Charles Darwin is doomed to for many eons. According to Talmud, the vast majority of people will experience this existence for a term ranging from a few years to a few millennia. The vast majority of people will obtain Eternal Blessing after earning it in This Life or the Next Life.
Everyone must follow the Seven Laws of Noah. As Jews, we do not view Muslims and Christians as sinners -- Islam and Christianity incorporate the aforementioned Laws. Anyone who is debating or considering Atheist arguments must remember that they may add millennia to their term.
Can suffering be measured mathematically? In my opinion, it can be. As I have written elsewhwere,
Physical pain is perceived by nociceptors. According to Wikipedia, "a nociceptor is a sensory neuron that responds to damaging or potentially damaging stimuli by sending "possible threat" signals to the spinal cord and the brain." Most nociceptors are located on human skin. There are about 20 nociceptors per square millimeter of skin. Overall, a human contains about 40 million nociceptors. Only 3 million of them are responsible for sensing noxious heat.
We can define one pain unit (pu) as the experience created by one nociceptor sending maximal-strength signal to the brain. Similar pain may be experienced by tens of thousands of nociceptors sending lower-strength signals to the brain.
An example of a mild pain is an injection for blood test or vaccination -- only 2 to 3 mechanical nociceptors are pierced by the needle. Thus the pain is about 2 to 3 pain units.
An example of severe pain is amputation of a digit of a small finger. Similar pain would be experienced if someone's digit of a small finger is submerged in boiling water. That pain has a magnitude of 1,000 to 1,500 pain units corresponding to the number of nociceptors affected.
An example of extremely severe pain is amputation of a foot. Similar pain would be experienced if someone's foot is submerged in boiling water. That pain has a magnitude of 60,000 to 100,000 pain units corresponding to the number of nociceptors affected. Prior to discovery of anesthetic in 1840s, such surgeries took on average half a minute.
Falling into hot acidic spring is an example of unimaginable pain -- far beyond most other extremely severe pain. This pain has magnitude of 4,000,000 to 5,000,000 pain units corresponding to the total number of thermal and chemical nociceptors. The most extreme pain would last about 8 seconds after which the nociceptors stop functioning. Residual pain of tens of thousands of units lasts about 3 minutes.
In This Life, no one can endure unimaginable pain for more then about 8 seconds. No one can endure extremely severe pain for more then a few hours. The worst kinds of long-term pain are likely within severe pain category.
In the Next Life, an experience unlike anything from this World is possible. This experience consists of long-term existence during which a person's Soul constantly experiences suffering 60 times greater then the maximum suffering possible in This Life.
In This Life, no one can understand the kind of suffering any Soul experiences during the process of Cleansing. This suffering may be based on the degree of Regret and Sorrow far beyond anything in this World. This suffering may be some new Sense unknown here.
