might happen certainly,” answered Barbicane, “but the consequences would not be so redoubtable as you would suppose.”

“How so?”

“Because heat and cold would still be pretty well balanced upon our globe. It has been calculated that if the earth had been carried away by the comet of 1861, it would only have felt, when at its greatest distance from the sun, a heat sixteen times greater than that sent to us by the moon⁠—a heat which, when focused by the strongest lens, produces no appreciable effect.”

“Well?” said Michel.

“Wait a little,” answered Barbicane. “It has been calculated that at its perihelion, when nearest to the sun, the earth would have borne a heat equal to 28,000 times that of summer. But this heat, capable of vitrifying terrestrial matters, and of evaporating water, would have formed a thick circle of clouds which would have lessened the excessive heat, hence there would be compensation between the cold of the aphelion and the heat of the perihelion, and an average probably supportable.”

“At what number of degrees do they estimate the temperature of the planetary space?”

“Formerly,” answered Barbicane, “it was believed that this temperature was exceedingly low. By calculating its thermometric diminution it was fixed at millions of degrees below zero. It was Fourier, one of Michel’s countrymen, an illustrious savant of the Académie des Sciences, who reduced these numbers to a juster estimation. According to him, the temperature of space does not get lower than 60° centigrade.”

Michel whistled.

“It is about the temperature of the polar regions,” answered Barbicane, “at Melville Island or Fort Reliance⁠—about 56° centigrade below zero.”

“It remains to be proved,” said Nicholl, “that Fourier was not mistaken in his calculations. If I am not mistaken, another Frenchman, M. Pouillet, estimates the temperature of space at 160° below zero. We shall be able to verify that.”

“Not now,” answered Barbicane, “for the solar rays striking directly upon our thermometer would give us, on the contrary, a very elevated temperature. But when we get upon the moon, during the nights, a fortnight long, which each of its faces endures alternately, we shall have leisure to make the experiment, for our satellite moves in the void.”

“What do you mean by the void?” asked Michel; “is it absolute void?”

“It is absolutely void of air.”

“Is there nothing in its place?”

“Yes, ether,” answered Barbicane.

“Ah! and what is ether?”

“Ether, my friend, is an agglomeration of imponderable particles, which, relatively to their dimensions, are as far removed from each other as the celestial bodies are in space, so say works on molecular physics. It is these atoms that by their vibrating movement produce light and heat by making four hundred and thirty billions of oscillations a second.”

“Millions of millions!” exclaimed Michel Ardan; “then savants have measured and counted these oscillations! All these figures, friend Barbicane, are savants’ figures, which reach the ear but say nothing to the mind.”

“But they are obliged to have recourse to figures.”

“No. It would be much better to compare. A billion signifies nothing. An object of comparison explains everything. Example⁠—When you tell me that Uranus is 76 times larger than the earth, Saturn 900 times larger, Jupiter 1,300 times larger, the sun 1,300,000 times larger, I am not much wiser. So I much prefer the old comparisons of the Double Liégoise that simply tells you, ‘The sun is a pumpkin two feet in diameter, Jupiter an orange, Saturn a Blenheim apple, Neptune a large cherry, Uranus a smaller cherry, the earth a pea, Venus a green pea, Mars the head of a large pin, Mercury a grain of mustard, and Juno, Ceres, Vesta, and Pallas fine grains of sand!’ Then I know what it means!”

After this tirade of Michel Ardan’s against savants and their billions, which he delivered without stopping to take breath, they set about burying Satellite. He was to be thrown into space like sailors throw a corpse into the sea.

As President Barbicane had recommended, they had to act quickly so as to lose as little air as possible. The bolts upon the right-hand porthole were carefully unscrewed, and an opening of about half a yard made, whilst Michel prepared to hurl his dog into space. The window, worked by a powerful lever, which conquered the pressure of air in the interior upon the sides of the projectile, moved upon its hinges, and Satellite was thrown out. Scarcely a particle of air escaped, and the operation succeeded so well that later on Barbicane did not fear to get rid of all the useless rubbish that encumbered the vehicle in the same way.

VI Questions and Answers

On the 4th of December, at 5 a.m. by terrestrial reckoning, the travellers awoke, having been fifty-four hours on their journey. They had only been five hours and forty minutes more than half the time assigned for the accomplishment of their journey, but they had come more than seven-tenths of the distance. This peculiarity was due to their regularly-decreasing speed.

When they looked at the earth through the port-light at the bottom, it only looked like a black spot drowned in the sun’s rays. No crescent or pale light was now to be seen. The next day at midnight the earth would be new at the precise moment when the moon would be full. Above, the Queen of Night was nearing the line followed by the projectile, so as to meet it at the hour indicated. All around the dark vault was studded with brilliant specks which seemed to move slowly; but through the great distance they were at their relative size did not seem to alter much. The sun and the stars appeared exactly as they do from the earth. The moon was considerably enlarged; but the travellers’ not very powerful telescopes did not as yet allow them to make very useful observations on her surface, or to reconnoitre the topographical or geological details.

The time went by in interminable conversations. The talk was especially about the moon. Each brought his contingent of
