# How many stars are in the universe?

#### Helio

The very distant galaxies are seen in their youth, hence numerous but with far fewer stars. The 2 trillion number of galaxies seems to be a reasonable extrapolation of the observations. But these galaxies will have less on average than our MW.

I enjoy thinking the star count for the observable universe is ....6.02x10E23! Not that I’m a mole lover.

Then 1 observable universe = 1 mole of stars!

6.02x10^23 atoms in a mole
6.2x10^18 eV in a joule.
1.602x10-19 joule in an electron volt
6.626x10^34 J s = Planck's constant
1.672x10^-27 kg = proton mass
What's with 6's and 2's?

Hmmm. That‘s interesting. Give me a minute‘s worth of seconds to think about it. Better, give me an hour of minutes. I’ll use my 60 HZ clock to time me.

The number sequence for Titus-Bode are all divisible by 6, with Earth and beyond. [0.4 is then added after dividing the sequence by 10]

This may have something to do with "666" and "The terrible twos". I will mull it over and get back to you.

Please don't encourage the whack-a-doodles with the "666" stuff...
