Into Unscientific

Ah Li Lie.

As the mantra of a certain Shinigami elementary school student.

For people like Xu Yun, these three words almost have a deterrent effect similar to "dao friends, please stay."

And if on the basis of this word, the speaker is limited to wheat, then its deterrent effect will be even greater.

Almost at the moment of hearing this sentence.

Xu Yun's relaxed expression suddenly froze, and a bad premonition emerged in his heart.

Then he turned his head mechanically and looked at the simple wooden shed where the sound came from.

Only at this moment.

Mai Mai was standing in front of a wooden table in the shed, and the unproven Fu Qing Wu Wei Xu Bo Tai Shang Ci Huang Da Dao Jun was frowning, looking at a few black and white photos on the table with a puzzled expression.

at the same time.

A few steps away from Wheat, Riemann, who was packing up Gauss's manuscript, seemed to have noticed the abnormality of Wheat.

So he put down the manuscript in his hand, walked to Mai Mai, and the two started talking like this.

Wheat first raised a photo in his hand, then pointed to the observation record on the table and said something.

soon.

Riemann's expression gradually became serious.

After a while.

Riemann made a waiting gesture to Mai, walked quickly to the side of Gauss who was not far away, whispered a few words, and brought his teacher back to the shed.

See this situation.

Suddenly Xu Yun couldn't stand still, and hurriedly walked into the shed.

When he entered the shed, Mai just finished talking to Gauss about something.

I saw Gauss propping his hands on the edge of the table, leaning forward slightly, observing something.

Seeing this, Xu Yun didn't make a sound to bother him, but nodded slightly to Mai Mai and Riemann, and then quietly stood aside and waited.

At this time, Gauss was concentrating on looking at the table, and did not notice Xu Yun's appearance at all.

After looking at the photos for a while.

He moved some of them to the front, took out a pair of magnifying glasses from his chest, and started to observe more carefully.

After more than ten minutes.

Gauss frowned and straightened up from the table.

I saw the prince of mathematics pressing his thumb on his cheek, and his index finger gently touching his chin, with a deeply puzzled tone:

"Strange, what's going on with this Erlente thing?"

But as he spoke, he noticed Xu Yun beside him, and his eyes lit up immediately:

"Hey, classmate Luo Feng, when did you come?"

"Not long after I arrived, I was chatting with Mr. Airy in front of me."

Xu Yun answered his question hastily, then pointed to the photo on the table and asked:

"Mr. Gauss, this is."

Gauss pondered for a moment, picked up a photo from the table, and said to Xu Yun:

"Student Luo Feng, look at this."

Xu Yun took the photo and looked at it seriously.

Ten seconds passed.

He raised his head again, with a more bewildered expression on his face:

"Mr. Goss, is there something wrong with this photo?"

Gauss gave him the number 2963 for this photo, which was taken in 1843 by the Roman Observatory in Italy.

Pluto's position is on the upper right side of the picture, and there are no other celestial bodies around it.

In Xu Yun's opinion.

In addition to the black and white background, the accuracy and field of view of this photo are perfect. It can be said to be the standard template for Pluto's early records.

But look at Gauss' expression.

Something seems wrong with this photo?

Then Gauss glanced at him, handed his magnifying glass to Xu Yun, and said:

"You look again with a magnifying glass, and pay attention to the upper left of Pluto."

Xu Yun took the magnifying glass and looked at it again.

This time, he finally found some subtle abnormalities:

At the upper left of Pluto's point of light, there is a tiny bulge!

This bulge occupies about 1/5 of the area of ​​the light spot, and it is almost impossible to distinguish without looking carefully.

The opposite is the upper right corner of Pluto, where it is a smooth arc.

See this situation.

Xu Yun's heart skipped a beat, and that bad thought became clearer.

Gauss did not notice Xu Yun's stiff expression, but pointed to the photo, and asked:

"Well, did you see it?"

Xu Yun could only nod his head, think for a moment, and said to Gauss:

"Professor Gauss, is it possible that the aperture of the camera is abnormal when shooting?"

"After all, there is pixel difference in this kind of image after zooming in. It doesn't seem to explain anything, right?"

Gauss shook his head decisively when he heard the words, pointed to the other images on the table and said:

"You're wrong, classmate Luo Feng, it's not just this photo that has abnormal protrusions."

"According to Maxwell's observations, there are at least eight photographs where this anomaly can be observed, and they are generally concentrated between 1840-1845."

When Xu Yun heard this, the hand holding the photo shook slightly.

Then he laughed dryly, looked at Gauss, and said:

"So Professor Gauss, what do you mean?"

Gauss picked up a photo casually, stared at it for a few seconds, and then said slowly:

"If I'm not mistaken, the anomaly on the image may be a companion star of Conan's star—note, it's a companion star, not a satellite."

"And estimate from the image. Its diameter may not be much smaller than Conan Star."

Hearing this, Xu Yun looked at his eyes, his nose, his mouth, and his heart, with a calm expression on his face.

But at this moment, there was a storm in his heart.

Mom!

Something big happened!

mentioned earlier.

The solar system beyond Neptune can be further divided into the Kuiper belt and the Oort cloud zone from near to far.

The celestial bodies in this part of the region are called trans-Neptunian celestial bodies because their positions or orbits exceed the range of Neptune's orbit.

Among them, Pluto is the standard template of trans-Neptunian objects.

Its average distance from the earth is close to 40 astronomical units, its apogee is about 7.376 billion kilometers, and its perigee is about 4.437 billion kilometers.

At the same time, the time required for Pluto to orbit the sun is also the longest among all planets:

It takes about 248 Earth years for one revolution, and six more Earth days for one rotation.

That's why Xu Yun is quite depressed sometimes - he said that the daily updates are 30,000, but he didn't say it was an Earth day. If calculated according to Pluto, his update volume is beyond the standard.

If we use the 243 earth days of Venus to calculate

Ahem, let’s get down to business.

all in all.

Under such distance conditions, the image recorded by the camera is very blurry.

It is very difficult to observe with the naked eye, let alone see its outline.

But—here comes the point, there is one exception.

That is the planetary opposition phase.

Some old color critics may read this word separately, but in fact, it refers to a special astronomical phenomenon.

The so-called opposition of stars.

It refers to an astronomical phenomenon in which it moves roughly in a straight line with the earth and the sun during its revolution around the sun, and the earth is just between the sun and the stars.

The star is at its brightest when it is at opposition, and this is generally the best time to observe it.

For example, two days after readers read this chapter, that is, July 20, 2022, is the moment of Pluto's opposition to the sun.

A few days before and after the 20th, stay until the sun goes down every day.

Pluto will then rise above the eastern horizon and be visible almost all night long.

Of course.

This still refers to the astronomical telescope.

We all know that the orbits of planets in our system are all ellipses.

Among them, Pluto is the outermost planet in the solar system, and its average revolution speed is only about 4.7 km/s.

The earth is relatively inner, with an average revolution speed of 30 km/s.

So almost every once in a while, Pluto will be overtaken by the earth, passively forming a phenomenon of opposition to the sun.

And it just so happens.

On September 15, 1843, it was an opposition node of Pluto, and it was the brightest one in a hundred years.

Another piece of knowledge.

That is before the invention of the radio telescope in 1937, the core factors that determine the observation effect are only the aperture of the telescope and the material of the lens.

For example, Tombaugh, the discoverer of Pluto in 1930.

The astronomical telescope he used was only 42 inches, or 1066.8 millimeters, which was much smaller than the "Totara" in the open space now.

After all, the Lowell Observatory where Tombaugh works is a private observatory after all.

Although the founder Lowell Thiela is rich, it is still not enough compared to the Greenwich Observatory.

The reason why Tombaugh was able to discover Pluto is largely due to good luck-Lowell's original purpose was actually to find life on Mars.

If compared horizontally.

The Naga telescope used by Tombaugh in 1930 was not even ranked in the top ten in Europe in 1850.

The actual ranking is about 13-15, which is about the same as the treasure of the town hall of Muchachus Rock Observatory.

Even more critical is.

Pluto is the only known dwarf planet with an enveloping atmosphere.

When Pluto is at its perihelion.

The atmosphere would be in a gaseous state.

And when Pluto is at its aphelion.

The gases in the atmosphere condense due to the low temperature and fall like snowflakes.

So in photos, its image feedback will be infinitely close to the concept of 'realism'.

Therefore, under the blessing of the above reasons.

Before and after Pluto opposition in 1843, some photos were taken, which can be called the clearest Pluto photos of this era.

Magnify these photos with a magnifying glass, and you can barely see a small bump, which is a satellite of Pluto

Charon.

Of course.

The reason why Xu Yun's hands trembled was not the simple fact that Gauss discovered the 'Conan Star' satellite, but because

"Strange."

I saw Gauss scratching his hair a little irritably, and said inexplicably:

"Conan's angular diameter is 0.065"-0.115", and its oblateness is less than 1%, which means that its rotation axis inclination will be very, very large."

"In this case, it can have a companion star, then this companion star will be tidally locked first, and secondly, its diameter can never be so small - its ratio to Conan's star is at least higher than that of the earth and the moon big."

"But in this way, the center of mass of Conan's star must be outside the star, so there is a problem with the deviation parameter we calculated before."

"What has actually happened."

Gauss's brows were tightly knit into a ball, his fingers tapped regularly on the table, his expression was dignified and puzzled.

According to his previous calculations.

There is a high probability that there will be satellites around Conan Star, and there may be a lot of them. After all, this is a very common thing in the universe.

Even if it is such an unlucky person as the earth, there is a moon to accompany it.

But the presence of a companion star is surprising.

The concept of a companion star is relatively common in stellar systems, such as binary star systems, three-star systems, etc. - the famous three-body system is a three-star system, and the prototype is Nanmen II.

The companion star of the sun has not yet been discovered. The previous scientific speculation about the companion star of the sun is on the other side of the sun, but this guess has been denied now.

At present, the relatively marketable one is called the Nemesis hypothesis, also known as the dark companion star hypothesis-if you can’t remember it, you can divide it into Neme+sis, ahem.

This hypothesis has been proposed for several years, and it holds that the sun has a red dwarf-like companion that exists near the Oort cloud.

The perihelion point is one light-year, and the aphelion point is three light-years.

This hypothesis can explain the periodic mass extinction of the earth, but recently there is a lot of meteorite evidence that the impact of meteorites on the earth is not periodic, so the acceptance of this hypothesis is still not high.

Of course.

Compared with stars, it is not uncommon for planets to have companion stars.

For example, in the HD158259 star system, there is a planet with five companion stars.

But the question is where is the distance of Conan star:

If the companion star is small, it is unlikely to be captured by a black and white camera anyway.

Only when the volume reaches a certain scale—for example, the diameter is one-third or even one-half of the host star—can it be recorded.

But once the companion star reaches this magnitude.

Then its ascending node longitude is at least above 200, and its orbital inclination cannot be lower than 0.050.

Thus.

A new problem arises:

With the existence of such a huge star, why is the value they calculated before correct?

for example.

There is a piece of sand in front of you, and it is known that a certain 50-jin iron ball fell from the sky.

You determined its landing speed through derivation, and calculated the impact of sand resistance, and finally determined that the iron ball would stop one meter below the ground.

Then you took the shovel and dug a meter into the ground.

Sure enough, you successfully found the iron ball.

Everything seems to be fine, we can open the champagne, right?

But when you weighed it, you suddenly discovered that this iron ball is not fifty catties, but tmd is seventy catties!

The landing speed remains the same, and the resistance of the sand remains the same.

According to the calculation of 1/2MV, it is obviously impossible for the 70-jin iron ball and the 50-jin iron ball to stagnate in one area.

But the actual result is over there:

It just appeared one meter below the ground, and there was only a few millimeters of error at most.

And unlike examples, the position of the planets is not deceptive, it just hangs there.

So thinking about it, there is only one possibility left:

Some unknown force reduced the kinetic energy of the iron ball to the order of fifty catties after it hit the ground.

Then Gauss thought of something again, and saw him pick up the paper and pen again, and quickly calculated on the table.

After more than ten minutes.

Gauss took a deep breath, his expression thoughtful:

"Sure enough, whether it is Conan alone or the influence of the companion star, there are still some problems with the orbit of Uranus."

Think here.

He turned his head involuntarily, looked at Xu Yun solemnly, and said:

"Student Luo Feng, do you think there is such a possibility?"

"It is somewhere farther away, in the depths of the starry sky as far away as possible."

"There is also a huge, undiscovered planet exerting a gravitational pull on Conan and its companion star"

I heard this.

Xu Yun's pupils shrank suddenly!

really.

Accidents still happen.

A few seconds passed.

He took a deep breath and did not answer Gauss's question.

Instead, he took the ax out of his body, stuffed it into his mouth, and began to chew.

Um.

Fortunately, I was resourceful, so I found a pastry shop and ordered an ax-shaped bread, which tasted pretty good.
