The first inflation of the universe began immediately following theBig Bang event. The second inflation took place approximately 9 billion years after the Big Bang event.
As I mentioned earlier ~1500 earth years= 1 unversal second, just as 1500 electron revolutions = 1 human second.

In fetuses the yolk sac provides instant nourishment to the fetus/zygot. However, it only has a finite quanitity of material. The umbilical cord begins forming roughly 5 weeks after conception.
This works out to roughly 4.5 billion electron revolutions. This is roughly half the time suggested. However, the gastrointestinal tract isn't completed until the 10th week at which time it protrudes into the umbilical cord. 10 wks works out to roughly 9 billion electron revolutions. Precisely the time needed to allow for the second inflation of the universe.
