A Case of Conscience

The count tried to turn the screen off, but he was too late. Before he could touch the black box, the whole circuit went out with a puffing of fuses. The intolerable light vanished instantly; the screen went black, and the universe with it. They sat blinded and stunned.

"An error in Equation Sixteen," the count's voice said harshly in the swimming darkness.

No, Ruiz-Sanchez thought, no. An instance of fulfilled desire. He had wanted to use Lithia to defend the faith, and he had been given that. Cleaver had wanted to turn it into a fusion-bomb plant, and he had got that in full measure, all at once. Michelis had seen in it a prophecy of infallible human love, and had been stretched on that rack ever since. And Agronski — Agronski had wanted nothing to change, and now was unchangeably nothing.

In the darkness, there was a long, ragged sigh. For a moment, Ruiz-Sanchez could not place the voice; he thought it was Liu. But no. It was Mike.

"When we have our eyesight back," the count's voice said, "I propose that we suit up and go outside. We have a nova to watch for."

That was only a maneuver, an act of misdirection on the count's part — an act of kindness. He knew well enough that that nova would not be visible to the naked eye until the next Holy Year, fifty years to come; and he knew that they knew.

Nevertheless, when Father Ramon Ruiz-Sanchez, sometime Clerk Regular in the Society of Jesus, could see again, they had left him alone with his God and his grief.

APPENDIX

The Planet Lithia (from Michelis, D., and Ruiz-Sanchez, R.: Lithia — a preliminary report. J. I. R. 4:225, 2050; abstract.) Lithia is the second planet of the solar type star Alpha Arietis, which is located in the constellation Aries and is approximately 50 light-years from Sol. [1]

It revolves around its primary at a mean distance of 108,600,000 miles, with a year of approximately 380 terrestrial days. The orbit is definitely elliptical, with an eccentricity of 0.51, so that the long axis of the ellipse is approximately 15 per cent longer than the short axis.

The axis of the planet is essentially perpendicular to the orbit, and the planet rotates on its axis with a day of about 20 terrestrial, hours. Hence, the Lithian year consists of 456 Lithian days. The eccentricity of the orbit produces mild seasons, with long, relatively cold winters, and short, hot summers.

The planet has one moon with a diameter of 1,256 miles, which revolves about its primary at a distance of 326,000 miles, twelve times in the Lithian year.

The outer planets of the system have not yet been explored. Lithia is 8,267 miles in diameter, and has a surface gravity of 0.82 that of Earth. The light gravity of the planet is accounted for by the relatively low density, which in turn is the result of its composition. When the planet was formed there was a much lower percentage of the heavy elements with atomic numbers above 20 included in its make-up than was the case with the Earth. Furthermore, the odd-numbered elements are even rarer than they are on Earth; the only odd-numbered elements that appear in any quantity are hydrogen, nitrogen, sodium and chlorine. Potassium is quite rare, and the heavy odd-numbered elements (gold, silver, copper) appear only in microscopic quantities and never in the elemental form. In fact, the only uncombined metal that has ever appeared on the planet has been the nickel-iron of an occasional meteorite. The metallic core of the planet is considerably smaller than that of the Earth, and the basaltic inner coating correspondingly thicker. The continents are built, as on Earth, basically of granite, overlaid with sedimentary deposits.

[1. An earlier figure of 40 light-years, often quoted in the literature, arose from application of the so-called Cosmological Constant. Einstein's reluctance to allow this "constant" into his scholium has now been fully justified, v. Haertel, J. I. R. 1:21, 2047]

The scarcity of potassium has led to an extremely static geology. The natural radioactivity of K40 is the major source of the internal heat of the Earth, and Lithia has less than a tenth of the K40 content of the Earth. As a result, the interior of the planet is much cooler, vulcanism is extremely rare, and geological revolutions even rarer. The planet seems to have settled down early in life, and nothing very startling has happened since. The major part of its uneventful geological history is at best conjectural, because the scarcity of radioactive elements has led to great difficulties in dating the strata.

The atmosphere is somewhat similar to that of the Earth. [2] The atmospheric pressure is 815.3 mm at sea level, and the composition of dry air is as follows:

Nitrogen 66.26 per cent by volume Oxygen 31.27 Argon, c. 2.16 CO₂ 0.31
