Yu Ze said euphemistically: "Director Wan, if there is a dwarf planet that intrudes from outside the solar system, how likely is this?" ”

"Huh?"

Wan Ronglong laughed at this question: "This possibility is too small and too small......"

"Is that not a possibility?"

Yu Ze still insisted on asking.

"It's not that this possibility doesn't exist, it's like if you're walking down the street, you're worried about being hit by a car, but are you worried about being killed by a shark falling from the sky?"

Wan Ronglong said with a smile: "The probability that is too low on the macro level is equivalent to non-existence." ”

Seeing that Wan Ronglong didn't care, such an attitude is actually understandable, the probability of a wandering dwarf planet breaking into the solar system is really similar to being stoned to death by a shark falling from the sky.

Yu Ze pointed to the white paper: "Director Wan, I have a request, can you calculate, if there is such a mass dwarf planet, if it falls into the sun, will it have any impact on the ecological circle on the earth?" ”

"Huh?"

Wan Ronglong looked down at the two rows of data on the white paper, shook his head and said, "No need to calculate, with a dwarf planet of this mass falling into the sun, no matter what, the earth's ecosystem will collapse." ”

Asking an astronomer this kind of question is like teaching an elementary school math problem in math.

Yu Ze nodded, the paper had been written very clearly, and the reason why he asked was not to confirm it again, but to lead to the next topic.

"Director Wan, let me assume again, if there is such a dwarf planet that is more than 115 astronomical units away from the earth, can we observe it now?"

Yu Ze asked again.

Wan Ronglong frowned, he didn't know why Yu Ze made so many assumptions, he was afraid that he would not have the patience to answer if he was another person, he was very busy.

But in the face of Yu Ze, a special talent, he also had to maintain considerable patience.

"No, more than a hundred astronomical units is too far away."

"Doesn't the Hubble telescope work either?"

"Haha, no, how to say it, the minimum resolution angle of the Hubble telescope is about 0.000000254rad, so if you want to distinguish stars 115 astronomical units away, the minimum resolution distance is 4369 kilometers."

Wan Ronglong calculated slightly, "According to the diameter of this dwarf planet you gave, it is far from reaching this resolution distance, and you have not given a specific star-seeking angle and ICRS." ”

"And what about the Webb Space Telescope? Can I find it? ”

Yu Ze asked again.

Wan Ronglong was surprised by Yu Ze's question and pondered: "The Webb Space Telescope is different from the Hubble Telescope, and its detection instrument is mainly an infrared camera...... Let me calculate the relevant probe wavelengths. ”

This calculation method is not difficult, according to the relevant formula of the Rayleigh criterion diffraction resolution limit, after knowing the aperture of the telescope and the detection wavelength, the minimum resolution of the detected celestial object can be calculated.

"If you use the near-infrared camera of the Webb telescope, it can provide a spatial resolution of 60 milliarcseconds, and at 115 astronomical units, the theoretical minimum resolution limit is 1937.44 kilometers."

Wan Ronglong quickly calculated the result: "The dwarf planet you provided is 2,500 kilometers in diameter, so it can be found by chance, but on the telescope, it can only image one point." ”

"I see, so if you find this point, can you calculate its size?"

Yu Ze continued to ask.

"Well, it was difficult in the past, but if there is infrared detection by the Webb telescope, and then the occultation method is used, it may be possible."

Wan Ronglong felt that Yu Ze's whimsical idea was very interesting, and quipped: "Actually, there is no need to be in such a hurry, since this dwarf planet is rampage in the solar system, when it enters the gravitational range of Pluto, it will inevitably perturbate the orbit of Pluto and even Neptune, and it will be easy to find out at that time." ”

"Then it's too late."

Yu Ze said.

Only then did Wan Ronglong notice that Yu Ze's face was very serious, and he didn't look like a joke. Since the acquaintance of this strange young man, all kinds of scientific common sense have been broken, so much so that the domestic physics community has wailed.

Originally, no matter how bizarre the physical phenomenon is, the physics community can study it with curiosity and composure, which may be something they are happy to see.

The reason why Yu Ze's special function makes them wail is that the special function does not follow the common sense of physics.

This is not a materialism that should be recognized and studied because there is a phenomenon, and the premise of materialism is that the phenomenon can be studied by scientific methods and tools, but what if it cannot?

For example, a paranormal phenomenon is like a super difficult mathematical problem, and mathematicians all over the world can't find a solution even if they cut their heads, but mathematicians admit that this is a mathematical problem, and the solution and argument can be found in theory.

And Yu Ze's special function seems to be a super difficult mathematical problem, but after a little research, mathematicians all over the world found that the essence has nothing to do with mathematics, and it is impossible for any mathematical tool to solve it, and it is impossible to solve it in the future, because this essentially violates 1+1 equals 2, it is like 1+1 equals 3, and it equals 4, and two numbers appear out of thin air.

Therefore, the institute is currently in such troubles, they seem to have found some rules, and after careful study, it seems that they have not found anything, and they are all in the air and cannot reproduce.

And research that cannot be reproduced is scientifically fatal, even if the fact of Yu Ze is here.

In the words of materials scientists, it is like developing a piece of room temperature superconducting material, anyone can prove that this room temperature superconducting material is real, but no one can reproduce the experiment, this is not a cheat!

In Wan Ronglong's perception of Yu Ze, this young man is very polite, very modest, has a good character, and occasionally can joke humorously, I really haven't seen him so serious.

"Ahem, Xiaoyu, your idea is very interesting, but in the end it's just an idea, you can't take it seriously."

Wan Ronglong coughed.

Yu Ze asked rhetorically: "Director Wan, do you believe in my special function?" ”

"Huh?"

Is there anyone who doesn't believe it now?

Wan Ronglong heard the other meanings in Yu Ze's mouth, and his face gradually became solemn: "Comrade Xiaoyu, why did you have such an idea?" ”

"Director Wan, I would like to know, can you ask NASA to conduct a search based on the data I provided, and determine whether there is a possibility of a wandering dwarf planet breaking into the solar system?"

As soon as Yu Ze said this, Wan Ronglong almost jumped up from his chair.

He stared at Yu Ze, his narrow eyes hiding some kind of consideration, "Comrade Xiao Yu, what you mean by this is to tell me euphemistically that an unrecorded dwarf planet has entered the solar system?" ”

"Yes."

Yu Ze looked directly at Wan Ronglong and did not avoid it: "A dwarf planet with a diameter of about 2,500 kilometers, estimated to be 115 astronomical units away from the sun, is breaking into the solar system at a speed of 120 kilometers per second, and it is likely to go straight to the sun." ”
