According to Jesse L. Greenstein, who was then head of the Astronomy Department at California Institute of Technology (personal conversation, Novemher, 1971), 1078 was the figure based on a 10-billion-light-year radius. Since 15 billion light years is now the accepted view, we calculate that the number of atoms is around 5 x 1078. (The earlier 1078 was approximate.) Current estimates of radius range from 10 to 20 billion light years, although there is still uncertainty of measurements beyond a few hundred light years.

Note that all through this chapter, the figures we used were those obtained under those tremendous concessions to make it easier for chance to succeed. Under realistic figures, the odds would have been even greater against its success.
