Are there more grains of sand on earth or more stars in the sky?
According to some estimates, there are 4.8 x 1022 grains of sand on Earth, and an estimated 5 x 1022 stars in the universe. The Bible says that there are a lot of stars in the sky and lots of grains of sand on a beach, and most of the other things referring to space in the Bible have been found to be true some thousands of years later. So they're about the same, give or take a factor of ~.2 :)
What is the number of particles in the universe?
It is estimated that there are 10^12 galaxies in the universe, each with about 10^12 stars. Each star has an average of 10^57 hydrogen atoms; using these estimates, the number of particles in the universe would be about 10^82.
What percentage of carbon dioxide is on venus?
In order to answer that question it is necessary to know how much carbon dioxide there is on Venus and how much is in the whole universe. Whereas the former can be estimated, there is little hope of estimating the latter to any degree of accuracy. However, based on the estimated number of galaxy clusters, and galaxies within those clusters, and stars within those galaxies with planetary systems, it is likely that the percentage of universal carbon dioxide that is on Venus is as close to 0% as makes no difference.
Is the number of stars finite or infinite?
