Data seems to be obtained from the two links I have added.

Just because there are large numbers does not mean that the universe is larger than those numbers. The estimates are based on the size of the observable universe (which is the only usable criteria) and the size of an atom (which is fairly well accepted). Factoring in the "average number of atoms in space" is what creates the wide range factor of 100 or more.

I don't know these numbers came from, but there are more atoms in the earth than that. Remember, A Google plex is 10 to the 100. There is no number that we can really comprehend that would tell us the number of stars in the observable universe, much less the number of atoms.

Is there anyway of knowing how large the universe is, therefore how can you estimate how many atoms there are?
