Liang Jing leaned back in his chair and rubbed his eyes, the time had reached half past nine in the evening, and his schedule had been irregular in the past few days, and the day and night were reversed.

Cassini is not the only one with a chaotic schedule, and everyone has to adjust their schedules to match the work when major holidays or missions are approaching - there is no such regular circadian rhythm on Titan as on Earth, the moon is firmly locked by Saturn's strong gravitational pull, and it rotates for as long as it takes to orbit, which means that a day and night in Titan has fifteen Earth days.

Life here is more like the polar regions of the earth, there are long polar days and polar nights, people's time allocation depends on clocks, in Cassini station, everyone's life time is staggered, because everyone's work tasks are different, under normal circumstances, Jiang Zi and Lao Hu get up at eight o'clock in the morning, rest at nine o'clock in the evening, and work thirteen hours.

Liang Jing is a workaholic, he gets up at 7 a.m. every day and works until 11 p.m., while the chef prepares food for everyone, he gets up at 6 a.m., takes a nap at 12 p.m., gets up again at 2 p.m., and finishes the whole day at 7 p.m. Mo Yu is the most special, her day and night are almost the opposite of others, she usually gets up at zero o'clock to work, goes to the kitchen to turn over food, until six o'clock in the morning, and then goes back to sleep, sleeps until two o'clock in the afternoon, and works until six o'clock in the evening and then rests.

Yaxiang had just come to Cassini Station, and she didn't have time to adapt to this complicated routine, so she often got up and went to bed with Moyu, and she was confused all day long.

For the Spring Festival, everyone in Cassini Station adjusted the time to the same, which they called "jet lag" or "time shift", and they had to go back after the Spring Festival.

What Liang Jing saw in front of him was the data of the black ball, which was the result of Dabai's analysis of that thing in the past few days, and all the data together was more than a dozen petabytes.

Dark blue numbers and letters scrolled on the screen, Liang Jing took a deep breath, Hu Donghai had also seen these data, but he didn't see anything.

Are the laws of physics really invalid in this black ball?

Liang Jing frowned.

This black ball is obviously not native to Titan, it comes from outer space, and the geological pit that Liang Jing excavated - Napoleon Pit, is an ancient crater formed 400 million years ago, although it has been completely buried, but the traces of the impact are still faintly visible.

In other words, when this black ball came to the solar system, the earth was still in the Devonian period, the dunkle fish was still the apex predator in the ocean, the amphibians had just come ashore, and even the dinosaurs had to wait another 200 million years for them to appear.

"Big White."

"Huh? Mr. Liang Jing? ”

"We were using a high-energy, short-wave laser to irradiate the surface of the black ball, and we didn't receive anything." Liang Jing said, "This is true no matter how much the frequency is raised, right? ”

"That's right."

"Is this a strong case that the black ball is not atomic?" Liang Jing asked.

"Do you mean there is no photoelectric effect?"

"Yes." Liang Jing nodded, "If it is an atomic structure, then it must have a photoelectric effect, any substance with an atomic structure, as long as the energy of the photons we irradiate is high enough, it can excite the electrons and form radiation that we can detect, but this black ball is not good, which means that it does not have an atomic structure, either there are no electrons, or the electrons are tied to death, and it is impossible to escape again." ”

"But that would be a violation of Pauli's principle of incompatibility." Great white reminder.

"yes...... How is it possible to tie an electron to the nucleus? Liang Jing muttered in a low voice, "This is really something that even immortals can't do." ”

No matter how they irradiate, there is no scattering, and there is no photoelectric effect, can this field not even be conserved in energy?

He has a headache, it's really like a mountain, even if they are all physics experts, but analyzing this damn black ball is not his field, in the most cutting-edge research frontier, no one can understand who is saying in the two laboratories separated by a wall, in the field of particle physics and theoretical physics, the director is better than Liang Jing, but he has died unexpectedly.

As it stands, Cassini is not equipped to study the black ball, because the real professionals are no longer there.

Further research can only be relied upon by sending it back to Earth.

"I have a corollary." Liang Jing said.

"Mr. Liang Jing?"

"Think about β decay, when they were studying β decay, they also thought that energy was not conserved." Liang Jing said, "This kind of thing has happened more than once in history. ”

Two hundred years ago, at the beginning of the twentieth century, physicists put forward the basic theory of quantum mechanics, but in the process, they found a phenomenon that may violate the law of conservation of energy, that is, the β decay of the atomic nucleus - the so-called β decay, is the spontaneous decay process of the atomic nucleus releasing electrons outward, in the study of β decay, people found that the energy taken away by the electrons is less than the energy lost by the atomic nucleus, which is like you bite off a piece of apple, But when you put the apple back together, you find that the gap is actually bigger than the one in your hand, one plus one is less than two, and some of the energy disappears out of thin air.

"That's because of neutrinos." Dabai said.

"Yes, because of neutrinos." Liang Jing nodded.

The study of β decay led directly to the discovery of neutrinos, and physicists discovered that energy did not disappear out of thin air, but became a particle that could not be detected by itself - it had zero static mass, no electric charge, and almost no interaction with any matter, so it ran away from under people's noses, but people did not notice it.

"Let's assume that this ball is a black box that can transform all the particles that hit it into some kind of particle that we can't detect, and like neutrinos, it has no mass, it doesn't charge, and it doesn't interact with the physical world, and all our current detection methods are ineffective against it." Liang Jing said, "In this way, we can fill the gap in the conservation of energy." ”

"However, existing physical theories do not predict the existence of such a particle." Dabai said, "In the system of physical theory, the position of this particle cannot be found. ”

Liang Jing groaned.

It's not his area of expertise.

It would be nice if Hu Donghai was here, although Hu Donghai may not be able to draw any conclusions, but it is better than his blind guess.

"Hmm...... There is a location. Liang Jing patted his head, "There is a big position, very, very big." ”

"What is it?"

"We predicted its existence a long time ago, but we haven't been looking for it for more than a hundred years." Liang Jing said slowly, "Dark matter...... And dark energy? ”
