Professor Qu also has a platform computer in his hand, and while operating the tablet, he said, "Academician Shen, please consult the document number A107. ”

Shen Qi clicked on the A107 file, and a large number of radio astronomy maps and related data were displayed in front of him, which came from FAST.

The powerful FAST accurately gives the spectrum of H2CO veins and H2CO absorption lines in the massive star-forming region, and the peak flow of the veins and absorption lines reveals the star formation and chemical evolution in the Milky Way to a certain extent, and provides necessary data support for the study of the large-scale structure of the Milky Way.

Professor Qu's team has completed the Doppler calibration, and the values in the spectral line mode parameter table have been densely brushed for more than a dozen pages.

This seems to be the prototype of a paper draft, and at the end of document A107, the eyes of Professor Qu's team are locked on the cantilever of Perseus.

More precisely, a nebula on the cantilevered arm of Perseus.

"A major discovery!" Shen Qi patted his thigh violently, and he asked Professor Qu, "When was this nebula discovered?"

"In February of this year, this nebula was detected for the first time by FAST. "We were surprised to find that its hydrogen abundance is much higher than that of conventional supernova remnants, which is not an order of magnitude at all." It is shaped like a butterfly with outstretched wings, and we will call it the Butterfly Nebula for the time being. ”

The Butterfly Nebula is more than 6,000 light-years away from the Earth, and the data in front of Shen Qi's eyes actually describes the state of the Butterfly Nebula more than 6,000 years ago.

As for Professor Qu's doubts, he didn't need to spend a long time to explain to Shen Qi.

There are pictures and truths, and Shen Qi can see the clues by looking at the atlas and data.

Floating in the vast dark void, the Butterfly Nebula is theorized to be a remnant nebula left over from a stellar explosion.

Through years of research, human scientists have established a mature system of astrophysical theories, in which the outer gas of dead stars will be blown away, and the core will collapse into tiny, dense neutron spheres and black holes that swallow everything.

However, the interior of the Butterfly Nebula has not been detected for neutron spheres or black holes.

Shen Qi fell into deep thought, why is this?

Professor Qu tentatively put forward his opinion: "Academician Shen, do you think it is possible that there is a large amount of dark matter inside the Butterfly Nebula? This is the only reasonable explanation we can think of. ”

Shen Qi's body shook slightly, but he did not reply immediately.

Shen Qi once predicted in the "Physical Framework Model", also known as the "Shen Qi Conjecture", that there is no dark matter in the universe.

Shen Qi also said in public that let's not spend too much energy on dark matter, it's better to pay more attention to antimatter research.

What the hell is dark matter? Some say it's a particle that hasn't been discovered yet, others say it's a projection from a higher dimension.

Stubborn physicists build huge tanks underground, hoping that dark matter will suddenly collide with the visible matter one day. They were desperate to witness the first glimmer of light from the collision of the shadows.

Unfortunately, dark matter never appeared.

Now, Professor Qu has enumerated detailed and credible FAST observations, and through reasonable logical deduction, predicted the presence of dark matter in the Perseus Cantilever Butterfly Nebula, which is located more than 6,000 light-years away.

was really predicted by Professor Qu, and Professor Qu was instantly upgraded to Big Guy Qu.

And Shen Qi will be mercilessly slapped in the face.

Of course, if dark matter does exist at the Butterfly Nebula, it will take a long time to detect it. Even if humans had built a light-speed spaceship or light-speed probe, it would have taken more than 6,000 years to fly to the Butterfly Nebula. It will take more than 6,000 years to transmit information back to Earth.

It takes more than 10,000 years to get a slap in the face, and who can live that long.

Shen Qi returned the tablet to Professor Qu: "Professor Qu, I need all the raw data. ”

Professor Qu nodded: "No problem, the original data has been copied and prepared for Academician Shen." ”

Shen Qi smiled and slapped Professor Qu's chest: "Okay, you old Qu, you have long guessed that I will be panicked, right?"

Professor Qu waved his hand again and again: "No, no, no, there is absolutely no such thought! Until Academician Shen answers our doubts, we will not disclose any information related to the Butterfly Nebula." ”

"I don't know when I can give a conclusion, you can't interrupt your research plan because of me, Lao Qu, what should your research group do, I suggest that you immediately publish an academic report on FAST's detection of the Butterfly Nebula, this is your hard work and achievements for many years, I heard that you don't go home for the New Year?"

"During the Chinese New Year, we take turns to go home, and we have to leave a few people to stick to FAST. ”

"Lao Qu, you just post an article and truthfully report the real data you have observed. We are scientists, we are ordinary people, we make mistakes as human beings, and my views are not necessarily correct. ”

"Thank you, Academician Shen, for your understanding and support. Professor Qu sincerely shook hands with Shen Qi, and he felt Shen Qi's personality charm.

Some people are very concerned about reputation, and you're going to slap me in the face, right?

Shen Qi was different, even if his theory was questioned, he smiled faintly and calmly.

Two days later, Shen Qi's father and daughter returned to the capital.

After this trip, Shen Nuofei and his father were closely connected, in the past, it was his mother who bathed Nofi, and now Nofei took the initiative to ask his father to bathe her.

After the May Day holiday, Shen Qi returned to work.

Shen Qi sat alone in the office, took a few deep breaths, and then entered a meditative state.

All kinds of information are surging in Shen Qi's mind, complete, fragmented, mathematical unification, four fundamental forces, physical framework model, Riemann conjecture, Hodge conjecture, N-S equation, P vs. NP, BSD, quantum entanglement, earthquake prediction, butterfly nebula, dark matter, antimatter, imaginary matter......

Things that have been experienced personally, things that have not been experienced but can be predicted, things that are difficult to foresee are purely YY's fantasies, present, future, real, ethereal, Shen Qi thought of a lot.

Human footsteps can never catch up with imagination, but imagination surpasses too much footsteps and is often considered unrealistic delusion.

Any imagination cannot arise in a vacuum, it always has an origin.

The reason why Professor Qu speculated about the existence of dark matter thousands of light-years away is because he makes a logically reasonable assumption based on the current situation.

How to answer Professor Qu's doubts?

It was impossible for Shen Qi to fly to the Butterfly Nebula to collect data in person.

How's that to be?

Shen Qi took a pen and wrote two words on the white paper: cause and effect.

After thinking about it, Shen Qi added a few more words, and the content on the white paper became: an operational model of cause and effect.

In fact, Shen Qi had this idea for a long time, and it was not because of a conversation with Professor Qu that the idea of the causal law model was born.

Can an operational causality model explain the singular features of the Butterfly Nebula?

Shen Qi felt that it should be possible.

Shen Qi took his daughter on a trip to FAST and met Professor Qu by accident, and it is inevitable to establish an operational model of cause and effect, which may be a kind of cause and effect.

In fact, Shen Qi had already played causal prediction many years ago, he predicted four earthquake points, guessed two correctly, and two coordinate points have been calm so far.

At this moment, Shen Qi suddenly realized, ten years, a whole ten years, I finally figured out a neglected but vital problem......
