Howdy.
Forgive me if I back up a little to post on an unresolved issue somewhat closer to the topic.

I will not argue about there being plenty of calcium in the sun. However, the authors of the Urantia Book explicitly make the claim that "there is a calcium layer, a gaseous stone surface, on the sun six thousand miles thick. " By my rough calculation, a calcium layer six thousand miles thick on the surface of the sun would make the sun about 2 per cent calcium. Current estimates put calcium at about 0.00019% of the sun. Somebody is off by more than a few orders of magnitude.

I was wondering, in these calculations, what figure was used as the density for gaseous calcium? Wouldn't this vary with temperature?(I assume we are referring to per cent by mass, not volume).
Mc replies:I did my admittedly very rough calculations based on volume not mass. Feel free to re do them using mass and a reasonable value for the densities of the gasses. That might reduce the 10,000 times order of magnitude discrepency somewhat. Let me know.
I did a little solar research. Other sources (Wikipedia for one) cite solar compositions as percentage of mass. The source you cite does not specify which, but its numbers are in general agreement with other sources, so I guess they must refer to mass as well.
It seems you've calculated percentage by volume using percentage by mass numbers. A pretty rough calculation, indeed.

The result of such a calculation is , of course, meaningless.
As for someone being off by several orders of magnitude, well.... As for reducing the "discrepancy" somewhat, since it's hard to have a discrepancy with a number that is meaningless, I'd say the discrepancy never existed. Thus your implication that this constitutes an example of where current science and UB disagree is not supported. Sorry, bro.
For the record, this in no way supports statements or validates anything about UB. A false argument against a proposition does not make the proposition true.
So, I figured as long as I'd come this far, I might as well do the calculations. Since math is hard to type, I'll describe the operations.
First, I figured the volume of a 6000 mile deep layer at the surface of the sun, 2.28x10^16 cubic kilometers. (Sound familiar, Mc?) Then, using the mass of the sun and the percentage calcium from your source, I calculate the mass of calcium present to be 7.18x10^18 kilograms. Using these numbers it is a simple calculation to yield the density of the supposed gaseous calcium. 3.15x10^-4 grams per cubic meter.
Is this a reasonable number for gaseous calcium?
I don't know.

The research I did on solar gasses revealed that they were actually plasmas at the surface. Plasma densities for the surface of the sun were given, but in particles per cubic meter rather than grams per cubic meter. I haven't figured out how to relate the two, but I will say this: Even if my calculations matched the UB numbers exactly it would prove nothing. I had to make a handful of dangerous assumptions to get where I could calculate anything at all. Not to mention the possibility of simple computational errors (I have no one to check my work). Any positive correlation might just as well be a happy congregation of errors. In the end, my research and calculations, while perhaps more diligent and more accurate than Mc's, are no more helpful to the discussion.
I don't know if UB is true, in part or as a whole. It doesn't matter to me. But if the point of this debate is to detemine whether it is reliable, or should be dismissed, in a debate forum we should be extra careful to avoid careless assertions, and perhaps leave the science to experts.
Mc: Nice tag line. My favorite verse.
