More support for about 2 trillion galaxies

[Helio]

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.

1E23 Suspiciously close to Avogadro's number, 6E23. Hmmm...

Pretty handy, huh?

Perhaps each Multiverse has one solar mole.

I'm still baffled by the fact that latitude 29.9792458°N passes through the top step in the Great Hall inside the Great Pyramid at Giza. The speed of light in m/s is 299792458. This is based on the distance from the equator to the North Pole. Both numbers based on the same thing. I'm scratching my head on this one.

Pretty amazing. Isn't it on a moving tectonic plate, so is it just now coming into alignment? Kinda odd. ain't it.

I'm unclear what you mean about them being based on the same thing?

The tectonic plate it is on, the African plate, is moving northward at 5" per year. In 150 years the line of latitude will dead center under the peak.

By "based on the same thing" I mean:
- Latitude is measured equator to pole as 90 full degrees.
- The meter was a ten millionth of the distance from the equator to the pole through the prime meridian.
