After leaving Chen Hao's house, Ye Zhou did not go home, but went directly to his office. Now his mind is full of radio issues and he can't fall asleep any longer.

For him, the information disclosed in the simulator is actually very clear, and the logical chain is also very simple, but it is not so easy for humans today to start this logical chain.

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

As of now, if sent in a directional transmission mode, humans can easily build up an equivalent power spectrum density brighter than the entire Milky Way at a certain moment, direction and band at a certain direction. However, when such directional transmission is turned into a "broadcast" mode, what humans can do is too primary.

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 are actually the most basic electromagnetic waves, and the equipment is just a radio telescope after amplification.

Although this method of transmission also has a certain effect, its radiation energy will attenuate before reaching the edge of the Milky Way. In the distance, even if there is a civilization, they will only receive clutter.

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

It is neither technically feasible nor practically achieved.

Ye Zhou hung up the phone in disappointment, and the broadcast within the Milky Way galaxy... This seems to be good, but in this way, the probability of the plan being successful is greatly reduced.

He frowned and searched relevant technical documents on his work computer, hoping to find a proven method, but with his current theoretical basis, even if he lists a lot of "possibilities", he cannot determine a truly feasible solution.

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

He sat up again with a sensation, swept his eyes to the door, and found that Lin Ling was coming in.

"Why are you not sleeping yet?"

Lin Ling asked in surprise.

"Why are you not sleeping yet?"

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

"I just finished the experiment... It's past three o'clock, do you want to stay up all night?"

Since the first time we met, the two have worked together in their respective positions for nearly two years. From being unfamiliar at the beginning to getting along with each other at the same time, to now, the two peers have finally gradually deviated from the original communication methods of routine and their relationship has become closer.

"I just went to find Chen Hao and handled something. I happened to be back and almost got information."

Hearing this, Lin Ling said thoughtfully:

"Are there any new technological breakthroughs to deal with something...?"

Ye Zhou nodded and replied:

"Well, it's a bit of a breakthrough in large fusion structures-------------------------------------------------------------------------------------------------------------

"What?"

Lin Ling pulled the chair in front of the desk and sat down. When she passed by the desk, she subconsciously glanced at Ye Zhou's computer screen, but she realized that the action was inappropriate, so she quickly withdrew her gaze.

Ye Zhou noticed her movements and said:

"It's okay, this is what I'm asking you to see."

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

Lin Ling was obviously interested in Ye Zhou's question. She threw an inquiring look at Ye Zhou. After receiving a positive answer, she directly pulled the screen to the coffee table in front of the two of them, and then jumped down from the chair and sat next to Ye Zhou.

"Let me take a look.....Electromagnetic radiation must be eliminated first. The attenuation rate is too high and the Milky Way cannot be found at all under the premise of large-scale broadcasting."

"Neutral communication, which can only be used for directional propagation, has passed."

"Sound wave communication... This is completely nonsense. No matter what the theory says, the vacuum is the fatal point of sonic communication."

"Weak force communication is currently only at 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 and cannot achieve the effect of broadcasting."

"We can't get so many quantum pairs, at least we can't get them now."

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

"And, the discovery of cosmic strings is only the first step. To construct a vibrating string that can produce enough energy, we need to at least use degenerate matter - this thing can only be taken from neutron stars."

"Add to the next level, if we can obtain degenerate matter, the scale of the vibration string that needs to be constructed is also exaggerated----A rough calculation, I estimate that it must be at the centimeter level, and the energy release must reach more than 50,000 kilograms per second."

"Well, if you can really do this, cosmic broadcasting is not difficult."

After hearing Lin Ling's words, Ye Zhou's face showed a bitter smile.

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

Humans can start the explosion by themselves!

It seems that all the roads are blocked.

He sighed and said:

"So in your opinion, in fact, all broadcasting methods are unreliable?"

"It's not unreliable, either... In fact, electromagnetic waves are the most reliable solution. Although the transmission distance is a little short, it's better than not."

"And, isn't this shortness that can reach the entire Milky Way relative to the cosmic scale?

"not enough."

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

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

The information should not be distorted and the transmission distance should be far enough---How is this possible?

Perhaps, setting up a relay station is a more feasible way, just like a cellular network arranged by humans on the ground.

However, the prerequisite for setting up a relay station is that humans must have the ability to fly to the edge of the Milky Way.

This is another new paradox.

After thinking for a long time, she sighed helplessly and spread her hands to Ye Zhou that she had no choice. Ye Zhou was not disappointed when he saw this. What he wanted from Lin Ling was not the final solution, but the reference to his ideas.

Now, his purpose has obviously been achieved.

He patted Lin Ling on the shoulder gently and was about to comfort him, but the other party suddenly raised his head. Then, when Ye Zhou was still stunned, he spoke in surprise:

"Actually, we can use electromagnetic waves!"

Ye Zhou was stunned and asked back:

"Didn't you say that the electromagnetic waves are not propagating far enough?"

Lin Ling nodded confidently and replied:

“Yes, definitely not far enough.”

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

"Mr. Ye, haven't you discovered that electromagnetic waves are beacons on the scale of the universe?"
