Seeing that the audience's attention was almost attracted, Chen Muwu dropped a bombshell that had been prepared for a long time. He pointed out that according to the theory of relativity, this kind of time travel can not only go to the future, but also go back to the past.
Sure enough, as soon as he finished his remarks, it caused quite a stir in the audience.
The few time-travel stories in ancient China are all inseparable from the "one day in the sky, one year on the earth" approach. Basically, they encountered some kind of opportunity and stayed for a period of time in a space where time passed extremely slowly. , after coming out of this space, returning to the original world again, only to find that hundreds of years have passed, which is the so-called going to the future.
But no one has ever thought that people can go back to the past.
Let me ask, who can live his whole life without a few regretful things?
In the face of regret, the Analects of Confucius borrowed from the words of Chu Kuangren: "You can't admonish those who have gone by, but you can still pursue those who have come."
Zhuang Xin in "Warring States Policy" advised King Xiang of Chu: "It is not too late to look after the dog when you see the rabbit; it is not too late to repair the dead sheep";
Even the former high-spirited young man Wang Bo lamented in the "Preface to Prince Teng's Pavilion": "The east corner has passed, and it is not too late to mulberry trees."
These philosophical words basically say that regret is already in the past tense. Since people cannot go back to the past, they can only look forward.
For thousands of years, this philosophy of regret has been deeply rooted in people's hearts.
But now Mr. Chen Muwu on the stage suddenly said that under certain conditions, people can go back to the past. How can we prevent other thoughts from arising in people's hearts?
Immediately afterwards, Chen Muwu, who had just finished drawing the pie, poured cold water on the newly enthusiastic audience.
He pointed to the cylinder previously drawn on the blackboard and told everyone that this kind of return to the past is theoretically possible, but it only needs to meet many specific conditions, such as enough energy, fast enough speed, etc. The current level of human science and technology is not enough to achieve this.
Just one or two sentences on boring theoretical knowledge is enough. If he talks too much, the audience will not like to hear it, and he will easily show timidity on stage.
Fortunately, Chen Muwu's control over the field was very good. He then asked the audience a question that basically had nothing to do with physics.
"Perhaps in our history, there have been several people who traveled back to the past through time from later generations. In order not to cause trouble for themselves, they did not reveal their identities, but we can still detect it from their actions. Some clues. Please think about it, are there any ancients in your memory who meet the requirements?"
This question made the noisy discussion in the audience even louder.
Even Mr. Lu Xun closed his eyes and frowned slightly, as if he was carefully searching his knowledge reserves.
After a long while, the audience still had no results from the discussion, so someone shouted from the audience: "Mr. Chen, we really can't think of such a person, why don't you give me an example!"
Chen Muwu cited Yuan Tiangang, Li Chunfeng, Shao Kangjie and Liu Bowen as examples, saying that they were able to write "Tui Bei Tu", "Plum Blossom Poems" and "Shaobing Song" probably not because of their magical calculations, but because they came from The future, so we can know the development of future generations.
He stopped here and did not dare to speak too absolutely.
Chen Muwu was very afraid that if he talked about this and got out of hand, he would be given the title of a "scientific stickman" and be attacked by a group of truly knowledgeable people.
Especially the fellow with a mustache in the audience, you should change the topic quickly before he frowns.
He didn't want such a classic curse word to be circulated on the Internet for future generations, which came from an article criticizing him in "The Complete Works of Lu Xun".
But the more mysterious he is, the more people in the audience think what he says makes sense.
Just one week after Chen Muwu's last lecture, there will be a debate between science and metaphysics in the academic world. Famous scholars have come out one after another, and both sides insist on their own opinions and refuse to give in to each other.
This debate was the first collision between the materialism that had just emerged in the country and the idealism that was deeply rooted in the hearts of the people. It lasted for two or three years without a winner.
People are already keen on these prophecies, and now that they have the "scientific explanation" made by Chen Muwu, they are even more convinced of them.
Chen Muwu's lecture had completely deviated from the track of physics, but the effect was surprisingly good, because he raised the next question for the audience to think about.
If humans finally built a time machine that could travel between the past, present and future conveniently and quickly, where would you most like to go? Why?
Where to go?
Definitely a step back in time.
What can you do if you go back in time?
Of course, it is to avoid regrets in advance!
Otherwise, why would there be a large number of time-travel and rebirth articles (including this article) in later Internet articles, but there are only one or two tenths of the science fiction articles describing the future world?
Of course, the situation is very different now, because before Chen Muwu’s lecture, people never knew that there was a theory that could support humans returning to the past, so there were more science fiction novels about going to the future.
Liang Qichao wrote "The Future of New China" in 1902, which predicted sixty years later, and the owner of Bihe Pavilion also wrote "New Era" in 1908, which imagined the country's situation in 1999.
Among them, the most classic one should be a fantasy novel titled "China Forty Years After the Founding of the Constitution" written in 1910 by Lu Shi'e, a novelist from Wuhan.
The general content of the book is that a man from the Qing Dynasty traveled to Baihai in the 43rd year of Xuantong (i.e. 1951) in a daze after drinking.
In Baihai at that time, the concession had long been taken back, trains were connected from Beijing to Shanghai, buildings were lined up in rows, people walked on the wide road, and a large iron bridge was built across the Huangpu River to Pudong on the other side. In order to facilitate visits to the "exposition" held in Pudong at that time, a cross-river tunnel was built, a subway was built, and so on.
In addition to errors in time and estimates of the lifespan of the Qing Dynasty, his novel's predictions about future generations are so accurate that many people believe that the author Lu Shi'e is actually a time traveler.
Chen Muwu's words aroused deep thinking in the audience.
This person is none other than Zhang Xinyuan, the reporter from "Yi Shi Bao".
Even though his real name is not famous, it is because he also has a well-known pen name called "Hate Water".
Zhang Henshui was not yet famous at this time. He only worked as a small editor under Cheng Shewo of Beijing's "Yi Shi Bao" and occasionally went out to run news.
Knowing that American Minister Shulman was going to attend a lecture at Beida University, he also came to the lecture today. Unexpectedly, he saw Chen Muwu standing on the stage.
When old friends met, not only Chen Muwu was startled, but Zhang Henshui was also stunned.
Isn't this the same person who went to the editorial office several times and submitted "The Legend of the Condor Heroes"?
Although he said that he was showing off for someone else and that the real author of the novel was Ms. Yao Fulan, after reading the novel, Zhang Henshui became increasingly convinced that this book could not have been written by a woman.
Now I see Chen Muwu talking about the hottest and most popular science on the podium of Bei Grand Auditorium, which further confirms Zhang Henshui's judgment.
No wonder he used a pseudonym to submit the article. It turned out to be to avoid exposing his identity and fearing embarrassment!
