Number of Sand Particles On Earth VS. Number of Stars

So... there was an estimated ratio based on two estimated numbers?

Hear it now: I say the ratio of stars to and particles is phi, not pi. Since you can't quantify *any* of the numbers, prove me wrong

I too have difficulty with the concept of just how large the universe is. Light from the far side has not reached us yet.

Hasn't red-shift proven the Universe to still be expanding?

Try Hubble in 1929.

Then we just need someone to go to the beach and start counting the sand.

On the one hand, if you say the universe is infiinte then there would be more starts, because there is a finite number of sand particles.

On the other hand, matter is supposed to be constant, so there would be a finite amount of it in the universe. In which case i would say the universe is bigger than the earth by many factors and therefore there are more stars.

Looks like there are more starts either way to me, if the relative mass of the earth can be estimated, then the amount of sand can be estimated, and i would imagine those who estimated the amount of stars and compared it to sand to come up with the statement that there are more starts than sand are using reasonable accurate estimations of both (Reasonable when you take into account the size of the universe finite or infinite).

So i would say there are more stars. Now are there more stars in the universe than there are sand particles in the universe, now there a question to get high and think about.

Yes, according to what I've read.
