Chapter 574: The Possibility of Time Travel
However, apart from a few brief written records, there is no other information to support the events that happened a thousand years ago .
"We don't have a time machine and can't travel back to the past. How can we possibly see what happened a thousand years ago?"
"Of course, theoretically, this is not impossible."
At this time, Xu You suddenly smiled mysteriously and said.
Lin Shi was confused again after hearing Xu You's words, which made Lin Shi scratch his head and ask:
"Teacher, is it even theoretically possible to travel back in time? Isn't this a bit unscientific?"
"It is indeed impossible , but it is definitely possible to travel to the future. Based on the existing knowledge, I already have two ways to travel to the future."
"Oh? Teacher, how can we do this?"
"The first way is to take a spacecraft that travels at or close to the speed of light, fly in space for a period of time, and when you come back, you will have traveled through time. According to the time slowing principle of relativity, your time will be much slower than that of other people on Earth. In this way, when you return, your children may be older than you."
"Teacher, I understand this principle, but with the current level of technology, there is still a huge gap in the ability to create a spacecraft that can reach or approach the speed of light. What is the other way?"
"Another way is to instantly move to a location a thousand light years away. At this point, if we have a very high-precision telescope and look in the direction of the moon without any obstruction, theoretically we can see what the moon will look like in a thousand years."
"But...how can we move to a place a thousand light years away in an instant? Isn't this more difficult to achieve than traveling at the speed of light?"
Xu You smiled gently, picked up a piece of A4 paper and folded it.
While doing this, Xu You said:
"As long as it is proven that wormholes do exist, then this kind of 'teleportation' will become possible. The universe is so vast, there are still many things we don't understand, and these are not unscientific things."
"Wormhole? This is a concept I learned from science fiction magazines when I was a kid. But come to think of it, we are even building space fighters, so it is not impossible to find wormholes. The distant celestial bodies we observe now are actually what they looked like tens of thousands or even hundreds of millions of years ago."
When the two thought of this, they felt an indescribable sense of sublimation in their hearts.
…
Xu You did get some useful information from this conversation with Johnson.
But these have not had any impact on our plans for lunar exploration and aerospace fighters, but have only strengthened our determination to research these technologies.
After many days of research, the "micro-fusion" project has been experimentally confirmed to be able to achieve various theoretical goals.
After completing the research on this core technology, Xu You and Lin Shi returned to Jijing University.
After all, they are both teachers at Jijing University and they can't stay outside all the time.
But returning to school does not mean that their research work is over.
In fact, several technologies related to aerospace fighters still need them to continue researching in the laboratory of Jijing University .
After returning to school, Xu You arranged his work and then picked up Lu Zhiyao to go home together after get off work.
"How is your work going recently?"
"Well, overall it went smoothly, and we basically completed the research within the planned time. Yaoyao, how about you?"
"I've been doing some research on natural philosophy related to aerospace recently. This is also what I did when I was in the Institute of Space Technology. However, I feel that the information I have is not hard enough and cannot support my research topic. I wonder if you have any aerospace-related projects recently? Would it be convenient for me to intern in your laboratory for a while?"
Xu You didn't expect Lu Zhiyao to make such a request, but he was very willing to help Lu Zhiyao with these requests.
"I'll apply to the higher-ups tomorrow. If everything goes well, you can come to my lab for internship. I think there should be no problem at all. You've participated in many large-scale projects before."
The internal secrets that Lu Zhiyao knew were no less than those of many internal scientific researchers. Including the incident involving Huang Sibai, there were only a few dozen people who knew the truth.
"Well, it's okay, let's wait for the result of the application."
Lu Zhiyao was more familiar with these processes and knew that these national secret research projects would not be disclosed to outsiders casually.
After the two returned home, they changed their clothes and washed up, and then began the most exciting part.
Brainwave communication.
This ability is possessed by only two of them in the whole world, and it is also a secret between the two of them.
After a period of improvement on the code, Xu You has added some new code combinations, so that he can communicate with Lu Zhiyao directly in Chinese.
After a round of brain wave exchanges, sweat soon broke out on the foreheads of Xu You and Lu Zhiyao.
After reading the message sent by Xu You, Lu Zhiyao typed out this string of text on her mobile phone and gave it to Xu You for verification.
"Well, Yaoyao, very good. Every word and every punctuation mark is completely correct. The efficiency of our information transmission is very close to the normal communication method."
"Hehe, it's all because of your good guidance." Lu Zhiyao said with a smile.
Xu You was very satisfied with their rate of progress. As long as the two of them practiced more, the speed of information transmission between them would even be faster than normal speaking.
Because of the different principles of information transmission, this method of transmitting information through brain waves is very similar to some communication equipment, which can transmit a large amount of information in a short time.
"Unfortunately, I still haven't mastered the technology to send information through brain waves." Lu Zhiyao said regretfully.
Up to now, Lu Zhiyao can only receive information and is unable to send any information through brain waves.
"It's okay. Being able to receive and translate brainwave information is already amazing. As for how to send information using brainwaves, it's hard for me to explain it clearly. Yaoyao, maybe you will be able to master it someday."
Xu You believed that he was not the only one who could master this ability which was not specially granted by the system.
For example, by performing some simulations in his mind, Xu You can use this ability to a certain extent even before this skill officially appears in the system.
