How many stars are in the universe?

[Admin]

Exactly how many stars are in the universe is impossible to know because we aren't sure of its scale.

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...
