Chapter 25 Chapter 25 Take a day off

Waking up on Sunday morning, I didn't have to be ready to go right away like I usually do.Even in such a deep place, it's nice to have a day off.Besides, I have become so used to our cave life that I hardly think of the sun, the stars, the moon, the trees, the house, the town, and the luxuries we used to think were necessary in our former lives.Living this ancient primitive life, we have stopped caring about unnecessary greatness. This cavern formed a hall, and its granite floor flowed from the Fountain of the Faithful.The spring water flows here from the source, and its temperature is already the same as that of the things around it, so it is not difficult to drink.After breakfast, the professor spent several hours organizing his diary.

"First," he said, "I'm going to figure out where we are now, and when I get back I'm going to draw a map of our travels, a map of the longitudinal section of the world, and put our itinerary in the above." "This must be very interesting, Uncle, but can your observations be made to a fairly accurate degree?" "Yes. I've carefully noted all the angles and slopes. I'm sure I can't make a mistake. Let's see where we are now. Get the compass and see what direction it is." I took a closer look and answered, "East by southeast."

"Well!" said the professor, noting the direction, and making a quick calculation, "we have covered two hundred and fifty-five miles from our starting point." "So are we traveling under the Atlantic Ocean now?" "Not bad." "Maybe there's a storm going on in the Atlantic right now, and we're rocking ships in the wind and waves above us." "Very likely." "Perhaps the whale is beating its tail against the wall of our 'prison'!" "Don't worry, Axel, a whale can't move this wall. Ah, let's go on. We're two hundred and fifty-five miles south-east from Snaefer, and by these points we're now underground. Forty-eight miles."

"Forty-eight miles!" I exclaimed. "good." "This is the limit of the crust!" "I dare say it's possible." "According to the law of temperature rise here, there must be fifteen hundred degrees Celsius!" "It must be, my child!" "Then all the granite must be melted!" "But you see the granite didn't melt; and the fact, as it always does, overrules the theory." "I had to agree. But it did surprise me." "Look at the thermometer, how many are there?" "Twenty-seven degrees six."

"So the scientists miscalculated by 1,472 degrees four! So the saying that the temperature goes up as you go down is wrong. So Humphrey Dawe is right, and I believe he is also right. What else do you have to say?" "There's nothing to say." I actually have a lot to say.In any case, I would not agree with Dawei's theory.I still believe in core fever, even though I don't feel it yet.I do agree with the statement that the vent of this extinct volcano is surrounded by a layer of inmeltable rock, so that the heat cannot be transmitted to it. But instead of arguing with him, I just put one thing to him about the situation:

"Uncle, I agree that your calculations are accurate, but allow me to draw an inference." "Do it quickly, my boy." "At the latitude of Iceland, the radius of the earth is about 4,749 miles, isn't it?" "Four thousand seven hundred and fifty miles." "Put it up to a whole number, and it's 4,800 miles. We've covered forty-eight of the 4,800 miles, which means we've traveled one hundredth of the way?" "just like what you said." "Running for twenty days?" "Exactly twenty days." "In this way, we need two thousand days, which means about five and a half years to reach the center of the earth!"

The professor didn't speak. "Besides, if we go down forty miles for every two hundred and fifty miles we go, it will take us a long time to reach the center of the earth!" "What a nuisance you are calculating!" said the uncle angrily. "Things will change. Besides, someone else has already done it, and if he succeeds, so can I." "I hope so; but at last I can be allowed to—" "You can be allowed to keep silent, and not to talk nonsense, Aksai." I also feel like it should be quieter. "Now," he asked, "where is the gauge pointing?"

"It's quite stressful." "Okay. You see we've gotten to this point slowly, but it's not inconvenient." "No, it's just a pain in the ear." "It'll be all right. Take a quick deep breath to equalize the pressure in your lungs with the pressure outside." "Yes, of course," I said, determined not to annoy him, "did you notice how clearly you heard?" "Yes, so that the deaf can hear." "But this density must be getting bigger and bigger?" "Yes, according to a law that is not quite certain, it will get bigger and bigger. The further we go down, the weight will be smaller and smaller. You know, when the object is on the surface of the earth, its weight is the greatest, At the center of the earth, there is no weight."

"I know that, but because of the increased pressure, the density of air will be equal to that of water?" "Of course, at seven hundred and ten atmospheres, it will have the same density as water." "What if it's lower?" "The lower it is, the denser it will be." "Then how do we get down? We're going to float!" "We can put stones in our pockets." "Hmph, uncle, you always have something to answer." I don't dare to assume any more, because I'm bound to run into some more questions that make the professor angry.

But obviously, when the air is under the pressure of thousands of atmospheres, it will definitely become solid. At that time, even if our body can bear it, we can't go any further and can only stop. At this time, all reasoning in the world It's out of the question. But I didn't say that.Uncle will certainly bring his immortal Saconusan against me again.In fact, it is meaningless for him to cite this predecessor. One very simple thing can explain that the travel of this Icelandic scholar is not true at all. In the 16th century, neither the barometer nor the manometer was invented. , How can Saknushan conclude that he has reached the center of the earth?

But I didn't say that.I just wait and see what happens. The rest of the day is spent calculating and talking.I often agree with Professor Liedenbrock's opinion, and envy Hannes' indifference. He doesn't consider the cause and effect at all, and blindly follows where fate wants him to go.
