How do you measure pain ? Where is the National Bureau of Standard's pain calibration reference ?
Nope... pain is real, but it is purely subjective. This is why doctors & nurses have to ask patients, "on a scale of 1 to 10, how much pain do you feel ? There is no 'painometer' they can use, like there are thermometers, sphygmomanometers, weightometers (mass scales), pH meters, etc.
As humans, we 'believe' in pain; or better put, we can 'believe' in the pain of others, so we know pain exists; because we know darn well we have felt it ourselves (on one occasion or another), but yet, there is no physical, objective way to measure pain.
There are physical, objective ways to measure distance, mass and time, and ways to measure all the physical phenomena that can be described by interactions and combination of these 3 fundamentals; but pain ? ... no, it cannot be measured.

Why would you focus so much on that? We can still test pain, feel it and know how or why it works. We cant do ANY of that with god, whats your point here?
