A recent Space.com article showed that a study of the CMBR revealed a normal matter quantity for the universe to be about 100 zeta suns. [A zeta sun number = 1E21]
Since I've seen, on several occasions, a 2 trillion galaxy estimate for the number of galaxies, then does the 100 zeta sun estimate make sense? Yes, IMO.
If we guess that the early galaxies had about 50 billion stars (perhaps 1/4 of today's galaxies), and there are 2 trillion of them, then we would have 5E10 * 2E12 = 10E22 or 100 zeta suns!
Too early to nail this down, but it's interesting.
