Simulation: Great Power Technology

After leaving Chen Hao's house, Ye Zhou didn't go home, but went directly to his office. Now he was so full of things about broadcasting that he couldn't sleep at all.

For him, the information revealed in the simulator is actually very clear, and the logic chain is very simple, but it is not so easy for today's humans to start this logic chain.

How to transmit information into the universe and what information humans should transmit to the universe have always been questions that human society is constantly exploring, but in fact, no one can give a sufficiently convincing answer to this question.

For now, if it is sent in the form of directional transmission, humans can easily stack up an equivalent power spectral density that is brighter than the entire Milky Way in a certain direction and a certain band at a certain time, but when such directional transmission turns When it comes to "broadcasting", what humans can do is too rudimentary.

Just now, Ye Zhou and Chen Hao woke up an expert from the Chinese Academy of Sciences by phone. After confirmation, they found that the so-called "broadcasting" activities currently carried out by Chouguo and Huaxia are actually using The most basic electromagnetic wave, the equipment is only a radio telescope after the scale is enlarged.

Such a mode of propagation certainly has a certain effect, but its radiant energy will attenuate before reaching the edge of the Milky Way. In further distances, even if there are civilizations, they will only receive clutter.

To parse out information from it is tantamount to parsing a person's whispers from the whistling of the wind thousands of kilometers away.

It is neither technically feasible nor practically achievable.

Ye Zhou, who was informed of the situation, hung up the phone in disappointment. The broadcast within the galaxy... This seems to be not bad, but in this way, the probability of the success of the plan is greatly reduced.

He frowned and searched for relevant technical documents on his work computer, trying to find an effective method, but with his current theoretical basis, even if he listed a lot of "possibilities", he could not determine the real feasible solution.

Ye Zhou sighed, got up, got out of the chair, and lay down on the sofa. He wanted to take a nap, but before closing his eyes, the door of the office was pushed open.

He sat up again in a rush, and glanced at the door, only to find that it was Lin Ling who came in.

"Why are you still not sleeping?"

Lin Ling asked in surprise.

"Why are you still not sleeping?"

Ye Zhou also answered her a question, and the latter smiled embarrassedly and replied:

"I just finished the experiment... It's past three o'clock. Are you going to stay all night?"

From the first time they met, the two have been working together in their respective positions for nearly two years. From being strangers at the beginning, to getting along with superiors and subordinates, to now, the two peers have finally gradually separated from the original routine communication. way, the relationship is also closer.

"It's not all night, I just went to see Chen Hao and dealt with some things, and I just came back with almost information."

Hearing this, Lin Ling said thoughtfully:

"Do something... is there a new technological breakthrough?"

Ye Zhou nodded and replied:

"Well, about the large-scale fusion structure, it's a bit of a breakthrough -- wait, let's not talk about this for now, I just have something to ask you."

"what's that?"

Lin Ling pulled the chair in front of the desk to sit down, and glanced at Ye Zhou's computer screen subconsciously as she passed the desk, but she immediately realized the inappropriateness of this action, so she quickly retracted her gaze.

Ye Zhou noticed her movement and said:

"It's okay, that's what I'm showing you."

"My question is, if I want to broadcast to the entire universe, and the broadcast information needs to be clearly delivered to every corner of the entire universe, what scheme should I use?"

Lin Ling was obviously interested in Ye Zhou's question. She cast a questioning look at Ye Zhou. After getting a positive answer, she directly dragged the screen to the coffee table in front of the two of them, and then jumped off the chair. Sitting beside Ye Zhou.

"Let me take a look.... Electromagnetic radiation must be excluded first. The decay rate is too high. Under the premise of large-scale broadcasting, it is impossible to get out of the Milky Way."

"Neutrino communication, which can only be used for directed propagation, is over."

"Sonic communication... This is complete nonsense. No matter what the theory says, vacuum is the dead end of sonic communication."

"Weak-force communication is currently only in a purely theoretical stage, and its operability is not as good as quantum communication - but the problem is that quantum communication is also point-to-point, which cannot achieve the effect of broadcasting."

"We can't get that many quantum pairs, at least not yet."

"At present, the only relatively reliable one is gravitational wave broadcasting. However, gravitational wave theory is strongly related to string theory. If you want to think that gravitational waves are produced, you must first discover cosmic strings."

"Also, the discovery of cosmic strings is only the first step.

To generate vibrating strings of sufficient energy, we need at least degenerate matter -- something that can only be obtained from neutron stars. "

"Going a step further, if we can obtain degenerate matter, the scale of the vibrating string that needs to be constructed is also exaggerated - a rough calculation, I estimate it is at the centimeter level, and the energy release should reach more than 50,000 kilograms per second. Just do it."

"Well, if you can really achieve this level, it is not difficult for cosmic broadcasting."

After hearing Lin Ling's words, Ye Zhou showed a wry smile on his face.

If you can really get the degenerate matter on the neutron star and even process it, then broadcast a hammer?

Humans can explode on their own!

It seems that all roads are blocked.

He sighed and said:

"So in your opinion, all broadcast methods are actually unreliable?"

"It's not unreliable... In fact, electromagnetic waves are the most reliable solution. Although the transmission distance is a bit shorter, it is better than nothing."

"Moreover, this shortness is relative to the cosmic scale, and it can reach the scope of the entire Milky Way, isn't it enough?"

"not enough."

Ye Zhou shook his head and repeated the details of the back-feeding plan. After listening, Lin Ling fell into silence.

She already understood the difficulty of this so-called "broadcasting plan".

The information has to be undistorted and transmitted far enough - how is this possible?

Perhaps, it is more feasible to set up relay stations, just like the cellular network deployed by humans on the ground.

But the premise of setting up relay stations is that humans have the ability to fly to the edge of the galaxy.

This is yet another new paradox.

After thinking about it for a long time, she sighed helplessly, and spread her hands to Ye Zhou to indicate that she had nothing to do. Ye Zhou was not disappointed when he saw this. What he wanted from Lin Ling was not the final solution, but the idea. refer to.

Now, his purpose has clearly been achieved.

He lightly patted Lin Ling on the shoulder, and was about to speak to comfort him, but the other party suddenly raised his head, and then when Ye Zhou was still in a daze, he said in a pleasant tone:

"Actually, we can use electromagnetic waves!"

Ye Zhou was stunned for a moment, and then asked:

"Didn't you say that electromagnetic waves don't travel far enough?"

Lin Ling nodded confidently and replied:

"Yes, definitely not far enough."

"However, in ancient times, the light signal transmission of the beacon tower was not far enough!"

"Ye Gong, didn't you realize that electromagnetic waves are the beacon on the cosmic scale?"
