Great Power Technology

After leaving Chen Hao's house, Ye Zhou did not go home. Instead, he went directly to his office. Now his mind was full of things about broadcasting and he could not fall asleep again.

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

How to emit information into the universe and what information humans should emit into the universe have always been questions that human society is constantly exploring. However, 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, then humans can easily pile up an equivalent power spectral density brighter than the entire Milky Way at a certain time, in a certain direction, and in a certain band. But when such directional transmission turns into When using the "broadcast" method, what humans can do is too rudimentary.

Just now, Ye Zhou and Chen Hao woke up an expert from the Chinese Academy of Sciences on the phone. After confirmation, they discovered that the so-called "broadcasting" activities currently carried out by both Chou Country and China are actually based on The most rudimentary electromagnetic wave equipment is just an enlarged radio telescope.

Although such a propagation method has a certain effect, its radiation energy will attenuate before reaching the edge of the galaxy. Further away, even if there are civilizations, they will only receive clutter.

Trying to decipher information from it is like deciphering a person's whisper from the roar of the wind thousands of kilometers away.

It is neither technically feasible nor practically attainable.

After learning about the situation, Ye Zhou hung up the phone in disappointment. Broadcasting within the Milky Way. This seemed good, but in this way, the probability of the success of the plan was greatly reduced.

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

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

He sat up again with a start and glanced towards the door, only to realize that it was Lin Ling who came in.

"Why aren't you sleeping yet?"

Lin Ling asked in surprise.

"Why aren't you sleeping yet?"

Ye Zhou asked her the same question, and the latter smiled sheepishly and replied:

"I just finished the experiment. It's already past three o'clock. Do you want to stay up 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 broken away from the original routine communication. way, the relationship is also closer.

"I won't stay up all night. I just finished looking for Chen Hao and took care of some things. I just happened to come back to get some information."

After hearing this, Lin Ling said thoughtfully:

"Is there any new technological breakthrough to handle something?"

Ye Zhou nodded and replied:

"Well, regarding the large-scale fusion structure, it is 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 her desk and sat down. When she passed the desk, she subconsciously glanced at Ye Zhou's computer screen, but she immediately realized that this action was inappropriate, so she quickly averted her gaze.

Ye Zhou noticed her movements and said:

"It doesn't matter, this is what I showed you."

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

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

"Let me see, electromagnetic radiation must be eliminated first. The attenuation rate is too high. It is impossible to get out of the Milky Way under the premise of large-scale broadcast."

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

"Acoustic communication is complete nonsense. No matter what the theory says, vacuum is the Achilles' heel of acoustic communication."

"Weak force communication is currently only in the 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 that many quantum pairs, at least not yet."

"Currently, the only thing that is relatively reliable is gravitational wave broadcasting. However, gravitational wave theory is strongly related to string theory. If you want to think about creating gravitational waves, you must first discover cosmic strings."

"Moreover, the discovery of cosmic strings is only the first step. To construct vibrating strings that can generate enough energy, we need at least degenerate matter--this stuff can only be taken 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 that it must be on the centimeter level, and the energy release must reach more than 50,000 kilograms per second. .”

"Well, if we can really achieve this level, cosmic broadcasting will not be difficult."

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

If the degenerate matter on the neutron star can really be obtained and even processed, then how about broadcasting a hammer?

Humans can explode themselves!

It seems that all roads are blocked.

He sighed and said:

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

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

"Moreover, this shortness is relative to the scale of the universe, and it can reach the scope of the entire galaxy. Isn't it enough?"

"not enough."

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

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

The information must not be distorted and must be transmitted far enough – how is this possible?

Perhaps, setting up relay stations is a more feasible approach, just like the cellular networks deployed by humans on the ground.

But the prerequisite for setting up a relay station is that humans must be able to fly to the edge of the galaxy.

This is another new paradox.

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

Now, his goal has obviously been achieved.

He gently patted Lin Ling's shoulder, and was about to speak to comfort him, but the other party suddenly raised his head, and then said in a surprised tone while Ye Zhou was still in a daze:

"Actually, we can use electromagnetic waves!"

Ye Zhou was stunned for a moment and asked:

"Didn't you say that the propagation distance of electromagnetic waves is not far enough?"

Lin Ling nodded confidently and replied:

"Yeah, definitely not far enough."

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

"Ye Gong, haven't you discovered that electromagnetic waves are beacons on a cosmic scale?"
