Goose feather snow drifted outside the window, and the occasional sparse sound of firecrackers and fireworks made this winter seem less silent. The layer of mist steaming on the glass shows that the heating effect in the house is good.

"Freshly baked leek meat dumplings~"

Mom trotted out of the kitchen with two plates of steaming dumplings laughing.

Dad picked up the chopsticks on the table and couldn't wait to try his wife's handiwork. When he saw his son, who was in a daze, he shook it in front of his eyes with chopsticks. "Son, what do you think? Are you still worried about finding a job? ”

However, Ding Beihai looked at his father with a blank expression.

"Haha, actually, I have already found a good errand for you!" Dad pretended to smile mysteriously, "An old buddy of mine told me that the Environmental Protection Bureau is short of people right now!" Let me tell you, environmental protection is very popular now! And my old guy is in a very high position inside, if my old Ding's son goes to apply for the Environmental Protection Bureau, maybe he can go through the back door for us! ”

Mom took off her apron, carefully hung it on the chair handle, and sat down as well. "Yes, yes, this job earns a lot of money, and it's close to commuting back and forth every day, and my mother agrees!"

Ding Beihai was unmoved. With one hand on his cheek, he looked at the fragrant dumplings on the table, without the slightest appetite. He replied with some annoyance: "How many times have I said it, you can't understand my ambition at all!" I want to build a time travel machine for the benefit of the future of the entire human race, how can I stay on such a broken civil servant? This is not only a waste of my life, but also a blasphemy and irresponsibility for the future development of mankind! ”

"Oh, I said Beihai, you have to see the reality clearly!" Dad put down his chopsticks, his expression and tone became serious, "Mom and Dad do understand your ideals and dreams!" But it's not just a matter of paying lip service. Scientific research requires not only a lot of basic knowledge, but also funding, connections, and collaborators. You see you still haven't written a word, why is the 9-to-5 job bad? ”

"The bird's ambition?" Ding Beihai threw his chopsticks and walked into his room.

The old couple sighed as they watched the door of the small bedroom slam shut.

"Now that this kid is older, he can't take care of it."

"Well, forget it, maybe he's right."

……

Ding Beihai came to the front of the building of the School of Physics of Huaxia University.

Looking at the trees on both sides of the research building, he silently recalled the night when he published his graduation thesis a few months ago.

It was a summer evening, and the sun had just set. In the 10,000-person auditorium of Huaxia University, 10,000 seats were full.

"Hello teachers, students, I am a graduate student majoring in astrophysics in the School of Physics, Ding Beihai." Ding Beihai was wearing a graduate student robe and a square hat, young, handsome and energetic, "My research topic is the practice and application of time shuttle, and the following is my defense. As we all know, in many science fiction novels and science fiction movies, the shadow of time travel is often seen, but as of now, human beings have not touched the edge of time travel. Ding Beihai talked endlessly, but the professors, lecturers, and classmates below all looked at him with frightened eyes. However, Ding Beihai didn't notice anything, and still spoke to himself, "And after my research and calculation, I found that the Einstein-Rosen bridge theory (that is, the black hole-wormhole-white hole theory) is completely feasible, so it is completely possible for human beings to travel in time and space!" ”

"It's complete nonsense!" Off the field, Ding Beihai's mentor, Sir Eddington from England, reprimanded his student loudly under the gaze of all the mentors, all the students, and even all the open media, "Time and space travel has long been recognized as a fallacy, just like a perpetual motion machine, why are you still continuing to study?" Don't you take the words of my guru to heart? ”

Ding Beihai stared at the mentor who looked like an angry leopard, his body hid behind the podium, and his legs were trembling at this time, obviously frightened. He trembled and put the speech on the stage, and carefully explained: "Einstein and Hawking have said that time and space are like a stretched plain cloth, and every mass celestial body will produce a pressure hole when placed on it, and this ......"

"Still obsessed!" Sir Eddington scolded and strode onto the podium. He came to Ding Beihai angrily, copied Ding Beihai's carefully prepared paper on "Time Shuttle and Practical Application", and tore it to shreds in front of everyone. Before leaving the scene in anger, he turned around and scolded angrily without saying a word: "It's too naïve, the surface generates space-time pressure, isn't it based on the fact that both the plain cloth and the celestial body are subject to gravity from the same direction?" What is the difference between using the gravitational pull emitted by a star to explain why gravity is prevalent in space-time and grabbing one's own hair and lifting oneself? ”

Ding Beihai pursed his lips, picked up the smashed paper manuscript on the ground, and walked off the podium, leaving a lost back.

……

Ding Beihai shook his head helplessly, shook off these thoughts, and returned to reality again.

This defeat did not defeat him completely, and he did not give up. In the history of physics and astronomy, Chandrasekhar, who proposed that white dwarfs could continue to collapse into neutron stars, is almost identical to his experience. However, the insistence of the strong Lasaka gave Ding Beihai inexplicable support.

Ding Beihai still firmly believes in the correctness of his theory, but his mentor's thinking is too old-fashioned and has no spirit of questioning, not only does he not admit his discovery, but even opposes it for a time.

However, this time Ding Beihai returned to Huaxia University in the hope of convincing several other tutors in the School of Physics, even if only one of them could accept his own topic! Then his research can be regarded as the beginning of the real sense!

But in the subsequent encounters again and again, Ding Beihai gradually lost confidence.

He bowed his head to the door of the last tutor's office and stood quietly. But when he looked up and saw the four big words "Believe in the Truth" posted on the door, he still mustered up the courage to knock on Professor Fairman's door.
