I think I solved that question plus answer... of why how everything...
It's a time paradox. How can I still exist if I go back in time and prevent my own father or mother from meeting? But the answer to the that is that an alternate reality would be created. Going further other alternate realities will branch off everytime you get a thought.
Think about the small dog swallowing a fleet of spacecraft.
Plus the question and the answer is part of the cycle. Suppose you make an accurate prediction of the future and tell everyone. All of a sudden a new reality branches off with that prediction added to the ongoing cycle.

A better method for calculating pi.
I you use a near infinite number base you will get a very accurate computation of pi. I can envision a massive computer capable of doing this. Pi is another example of a paradox, or more like an anomaly of 2 dimensions. A square is flat digital representation of 2 dimensions, a circle is the infinity end of 2 dimensions. Both are polar opposites of the same cycle.
