Liang Jing and Jiang Zi buckled their helmets and got out of the car, lifted the drilling machine from the trunk of the walking car, and stood on the ice, the tripod was driven into the ice with screws, and the two stood on the ice field around the tripod, like two ice fishing Eskimos.

The punch machine uses a high-energy pulsed laser as a tool for drilling, and Liang Jing needs to drill a 10-kilometer-deep ultra-deep hole vertically down, and the world's deepest hole drilled by the Soviets on the Kola Peninsula was only 12,000 kilometers, which is the technical limit of the twentieth century, but this is nothing for Liang Jing, as long as he wants, the drilling machine on Titan can easily break this record.

Kilometers below their feet are covered in ice and frozen ground, and it's much easier to drill holes than the hard rock that can be found all over the planet, with no need to pump mud, no water to cool down, and no need to worry about the drill bit breaking into the ground.

The high-energy laser uses X-rays, Liang Jing and Jiang Zi can't see the pillar of light, but after the drilling machine is turned on, a small hole appears in the ice instantly, and the ice immediately sublimates and volatilizes at high temperatures, and this borehole goes vertically downward, breaking through the thin shell of the outermost layer of Titan's surface, Liang Jing said that the stratigraphic structure of Titan is like a loose mille-feuille, more than ten kilometers thick ice layers are stacked layer by layer, which is full of voids, and the voids are filled with liquid alkanes, just like the earth's oil fields.

"The sea is shallow beneath our feet." Liang Jing said.

"Very shallow?" Jiang Zi didn't understand what this meant.

"Literally, it's a shallow sea." Liang Jing said, "In fact, there is an ocean underground, and in a deeper place, 200 kilometers underneath, there is an endless and unfathomable underground ocean, which is forever in absolute darkness. ”

Jiang Zi thought for a moment and shuddered, "I have a phobia of the deep sea. ”

"To be honest, if life does exist in this place, then the most likely place for them to exist is in the ocean underground, but unfortunately the ice is too thick for us to find them." Liang Jing said, "The temperature of the underground ocean is much higher than the surface, and it is rich in inorganic salts, which is more suitable for living organisms. ”

Jiang Zi glanced at his feet and stomped his feet vigorously, "Don't talk nonsense, the life born in the eternal night will not have eyes." ”

Liang Jing smiled.

The punch is still working, the laser drill is changing direction, and the first hole is not really a penetrating hole, but a pressure relief and ventilation hole.

"I'm reminded of the Kola drill hole I've seen before." Jiang Zi looked at the small holes in the ground, "Those nonsense stall literature often say that the Maozi punched holes and went to hell, and heard the howl of demons in the deep hole, and then accompanied by a photo of the Mir diamond mine, they don't want to think, how can such a deep hole be tens or hundreds of meters in diameter?" The hole won't have collapsed long ago. ”

Jiang Zi bent an arc with his thumb and forefinger, "The inside of the real Korra Drill Hole is actually so thick that it can be blocked by dropping a can, if a demon can be drilled out of this kind of place, it must be a demon in the Flying Noodles God Cult." ”

Liang Jing shrugged.

"There is a long way to go in popularizing science for the whole people, not to mention that compulsory education has been implemented for more than 100 years, in fact, there are still a large number of people who can't distinguish between electromagnetic radiation and ionizing radiation."

Jiang Zi was stunned.

"What's the difference between the two?"

The hole drilled by the drilling machine is only 20 centimeters in diameter, and the high-energy laser will send back geological data as it descends, and the depth number on the display has jumped to 2,588 meters, which is simply an astonishing speed.

"We've just crossed a fault line." Liang Jing suddenly became a little nervous and stared at the monitor.

"Will the hole collapse?"

"The fault is unstable, and there is a risk of collapse of the borehole." Liang Jing replied, "If this hole is blocked, then we will have to make a new one." ”

Jiang Zi squatted down and sat down, "We should inject mud into it, do you know how people used to make holes to prevent collapse?" It is to fill it with muddy water, which is called mud wall protection, and mud can prevent collapse. ”

"You're building a bridge and laying the foundation, and the mud in this place will freeze hard." Liang Jing squatted across from him, "The ice is in better condition than the soil, so don't worry about it collapsing." ”

"It would be nice if Lou Qi was still here, that thing is so good at computers, it's really a hell of a thing...... Inexplicably, even the shadow is gone. Jiang Zi said, "I don't know anything about physics, is it really that ghost of some kind of wave function collapse?" Quantized? ”

"How is that possible?" Liang Jing sneered, "Undecided quantum mechanics? ”

Jiang Zi looked at him and waited for an explanation.

"Quantum mechanics is quite mysterious, but this mystery is not the metaphysics you think, it is mysterious because it goes against human intuition and common sense, not against mathematics and physics, in the final analysis, quantum mechanics is still a solid foundation of natural science, is a reasonable extension of classical physics in the microscopic field, it is no different from Newton's second law, the only difference between the two may be that quantum mechanics is more difficult to understand, because there are not many people who can pass the high mathematics examination in college." Liang Jing said, "As for Lou Qi's sudden evaporation from the world, where does it conform to the theory of wave dynamics?" This in itself is contrary to our current theory of natural science, and it has nothing to do with any observation that causes the wave function to collapse, not to mention that it is not observation that causes the wave function to collapse, but measurement. ”

Jiang Zi looked dazed.

"It's because there are too many people like you, the stationmaster, that quantum mechanics is getting more and more bizarre." Liang Jing shook his head, "The disappearance of Lou Qi itself is a violation of all existing physical theories, so why force it into the category of quantum mechanics?" ”

"So it's not a wave function problem?"

"It's not." Liang Jing said, "Compared to this, I prefer to believe that the black ball is a wormhole, and Lou Qi has drilled into the wormhole...... It's more likely. ”

The first pressure relief channel has been laid, and the two of them got up and adjusted the position of the drilling machine, so that there will be three such channels in total, and the deepest exploration hole will be hit at the end.

Jiang Zi thought for a long time with his hands crossed, and finally decided to give up thinking and be a happy ignorant person.

Professional things should still be left to professional people to do.

The black ball is not in his domain.

"Don't think about it, in Muyu's words, the more you think about it, the faster the SAN value will fall, and you may go crazy at some point." Liang Jing pressed the button on the control panel of the drilling machine, "Let's take a fresh look at this black ball at most, satisfy the curiosity psychology, I really want to open it and look at it, and wait for the World Physics Conference on the earth." ”

Jiang Zi imagined this scene: thousands of physics masters from all fields around the world gathered together, sat around a smooth black ball, everyone rationally discussed a hundred schools of thought at first, then some people began to quarrel and not give an inch, then the masters carried chairs and threw teacups and fought together, and finally went crazy collectively.

Later generations will record it and say that it was a bloody case caused by a black ball.

But what about the ball?

The ball sat motionless on the plate.

Stand by and watch.
