Jim,
    There was a lot of very interesting and timely things in that article, for sure.
What I wasn't able find, was how they developed that equation.
Apparently each  Ii  is a function of time.
What is   Ii  measuring, that changes over time?
What kinds of changes to it occur over time?
When is t=0?
Was it at the beginning of creation?
If so, why is it integrated up to infinity, and not to the second advent, or to the new heavens and new earth?
If not, then why not, then, integrate from minus infinity to positive infinity?
Then there a number of   Ii  functions,  Ptotal  of them.
Apparently, the sum of the integrations of each function arrives at something describing a prophetic conclusion.
Would that be the start, climax, or intensity of the tribulation, or the battle of Armageddon?
