Voyage of the Stars

All right!

Yue Yuan was silent for a moment, then asked: "Haven't we already established the unified theory of weak currents a long time ago? What? We can't use it?"

The unified theory of weak electricity, that is, the unified theory of electromagnetic interaction and weak interaction, has been completed by humans in the twentieth century.

"Our electroweak unified theory is not wrong, but it cannot fully explain everything that happens at the signal transmitter of the neutrino communicator."

The answer was not Zhao Youqin, but particle physicist Liu Miyan who walked into the cabin with Yue Yuan.

The loud-voiced particle physicist cleared his throat, stepped forward and patted the casing of the neutrino communicator with his hand: "This thing cannot be completely solved by using the renormalization and quantization method. Applying perturbation theory to quantum field theory The divergence difficulties that arise during the calculation process do not mean that our gauge field theory method is wrong, but that it seems to need another method to supplement it.

We have not found this method, but based on the correlation of scientific development, we think that method is hidden in quantum electrodynamics, but we have not found it yet. "

"The mathematicians have just accumulated a few formulas, but they probably don't know what those formulas mean."

Liu Miyan shook his head. Apparently he went to find a mathematician to study with him, but the result disappointed him.

Since mathematical research is always far ahead of real physics, human physicists are always used to looking for it in mathematics when they cannot solve a problem using physical methods, hoping to find a suitable formula by rummaging through the mathematical toolbox. .

This method has actually been used by a physicist, and he has actually found a solution.

Not to mention, scientists who work on mathematical formulas often come up with mathematical formulas that even they do not fully understand, just like "Schrödinger did not understand the Schrödinger equation, and Dirac did not understand the negative solution to the Dirac equation."

"After all, it is about advanced civilization. It is good that we can understand so much in a short period of time." Yue Yuan first affirmed the efforts of the scientists. He sat at the head of the conference table arranged in the cabin. , and then said, "There is a long way to go for research. Now let us first see what the 'mine patroller' wants to do."

Zhao Youqin opened the computer screen on the conference table, then connected it to the Hope data center, let the 'Light of the Galaxy' connect to the equipment, and then looked at Yue Yuan.

"Everything is ready to start at any time. For safety reasons, we do not establish a direct call mode with the other party, but use the method of sending 'text messages'."

After seeing the scientists and many scholars who came with him sit down, Yue Yuan nodded and said: "Okay, let's get started."

Hearing Yue Yuan's words, Zhao Youqin looked at the computer screen hanging on the wall, opened his mouth and said: "'Light of the Galaxy', activate the Mok Star language dialogue module, and prepare to input information into the neutrino communicator."

"Understood, sir, it's ready. Now you can say what you want to send. I will translate it into the Mokxing language code and then transmit it to the neutrino communicator storage module." The loudspeaker equipment sounded and the real person Almost the same electronic synthesized sound.

After Tianhe Light finished speaking, the cabin became quiet, and everyone looked at Yue Yuan. The meaning was obvious, but let him speak.

Yue Yuan was silent for a moment, then raised his head and looked at the screen.

"Hello, mining patrolman of Mok Star Civilization, we are the expedition team of human civilization. We have received your communication signal and have created a neutrino communicator according to the method you provided. So now, we can talk in detail Is there anything between you and us?"

"What is the help you are talking about? Since you discovered our landing long ago, you must know our technological level. Why do you think we are so weak and capable of helping you? And what happened to your civilization? Yes. Tell us, what form does your civilization take?"

While Yue Yuan was speaking, the content of what he said was simultaneously displayed on the computer screen. After saying this, Yue Yuan looked away from the screen and then turned to Zhao Youqin: "This is all for now, send it out!"

Zhao Youqin nodded in response, and then did not get up. He just pushed his feet on the floor a little, letting himself follow the office chair and float out backwards.

When the office chair stopped, he reached out and pressed a button on the neutrino communicator to send the transcoded words of the 'Light of the Galaxy' to the planet Ross 154-4.

At this point in time, the straight-line distance between the Ross 154-4 planet and the Ross 154-7 planet where humans are located is about 1.8 astronomical units, and is separated by the giant gas planet Ross 154-5.

For this kind of relative position between celestial bodies, if it is general electromagnetic wave communication, a relay station must be used.

Neutrino communication is not required. Signals using neutrinos as carriers can directly pass through Ross 154-5 and go straight to Ross 154-4.

From the perspective of an observer, it takes about 8.2 minutes for light to travel a distance of 1 astronomical unit. This is also the reason why people say that it takes eight minutes for light from the sun to reach the earth.

Neutrino has mass, so it cannot reach the speed of light, but it is very close, about 0.9999999999999999995 times the speed of light. It is basically no different from the speed of light at a distance on the astronomical unit scale.

Therefore, from the time Zhao Youqin pressed the send button, from a human perspective, it took 14.97 minutes for the neutrino signal to reach the planet Ross 154-4.

If the mining area patrolman replied to the message in seconds, then humans would have to wait at least half an hour to receive the reply.

You can imagine chatting with friends, and having to wait half an hour for a reply every time you say a word, or both parties replying to messages instantly. This communication efficiency is indeed too unfriendly.

But there is nothing we can do. The universe is so vast, so vast that sometimes it is difficult to intuitively feel its breadth just by imagining it.

Just like the distance of 1.82 astronomical units, it seems far at first glance, but it doesn't seem that far. After all, in science fiction movies, you can always see scenes where the two parties are in different star regions but can communicate in real time. As a result, most people have no idea about the vastness of the starry sky.

The speed of light, the fastest speed in the universe, really makes humans feel the despair of the vast starry sky.

Quantum entanglement does have ghostly effects at a distance, but its use in super-light communication has been proven to be unfeasible. If there were no other means of communication, how slow would the pace of cosmic civilization be?

From the previous message sent by the patrolman of the mining area of ​​Mok Star Civilization, the people on the Hope now know that even the second-level civilization cannot master long-distance communication technology.

I don’t know if the Moke civilization has mastered super-light communication, and what level of civilization they belong to.

"In addition, ask them what level of civilization they belong to, and what level of civilization we belong to." Yue Yuan, who was imaginative, added.

Since the mining area patrolman has seen human landing transport craft, Yue Yuan should be able to judge the level of human beings.

Anyway, the other party wanted to ask for something, so I took this opportunity to ask more questions.
