Chapter 340 Goodbye, 1850! (5)
"."
Look at the light curtain in front of you.
Xu Yun's heart suddenly twitched hard!
If it is said that Gauss's calculation process is likely to have the possibility of some errors and omissions, leading to misjudgments in the final results.
Then the emergence of the halo prompt is undoubtedly an affirmation from the rule level:
They really found the mysterious Planet X!
Or rather.
PlanetNine!
And this light curtain that appeared in front of him also meant that Xu Yun could raise his hands to the sky and shout, "My mission is completed!"
But at this moment.
But he had no intention of doing so.
After all
The countdown that keeps jumping reminds him of one thing all the time——
He can stay in the copy, or in the time of 1851, as 'Luo Feng'
Not much left.
Wheat, Laotang, Aveline, Faraday, Gauss, Riemann, Kirchhoff, Ax.
In four hours, we will say goodbye to him forever.
Fortunately, Xu Yun has experienced the separation of dungeons in 1100 years, and is already somewhat prepared for this kind of separation.
In addition, most of his acquaintances are here tonight, so four hours is enough to do something.
Therefore, Xu Yun forced himself to calm down and turned his attention to Planet X in front of him again.
After all, there are still many aspects of Planet X that have not been dealt with.
He thought for a moment, raised his head, and said to Gauss:
"Professor Gauss, I think the name God King is quite good - but there are many God Kings in Europe. Which one do you plan to use as its alias?"
Readers who have done European gods in a previous life should know this.
In ancient European mythology.
There are six figures in total who are called 'god-kings', half of them each from Greek and Norse mythology.
The three generations of god-kings in Greek mythology are:
Ouranos, Cronus and Zeus.
Cronus is the youngest son of Uranus, and Zeus is the youngest son of Cronus.
Ouranos was the first god to rule the universe and was later overthrown by Cronus.
Cronus was the second god to rule the universe, and was later overthrown by Zeus, who became the third god to rule the universe.
True father is kind and son is filial.
The three generations of god-kings in Nordic mythology are:
Bree, Bol, Odin.
As of 1851.
Ouranos was nicknamed Uranus.
Cronus is the name of Saturn.
Zeus is the name of Jupiter.
Therefore, the only candidates left for Gauss to give another name to the god-king are the three generations of god-kings from Nordic mythology.
Of course.
It’s not impossible to name it after the height of Gauss. After all, Gauss is considered the God King in the world of mathematics, but that would be the star of Gauss
"Alias"
After hearing Xu Yun's words, Gauss just thought for a moment and quickly gave the answer:
"Just call it Odin."
When Xu Yun heard this, his pupils shrank imperceptibly.
Is this a coincidence?
Mentioned earlier.
The later BSC supercomputer that deduced the general formula of ring celestial bodies was also called Odin
Then Xu Yun coughed lightly and tried to make his expression look normal.
Continue to ask Gauss:
"Professor Gauss, can you let me see the observation records of King God?"
Gauss nodded, picked up a stack of thin documents from the console, and handed them to Xu Yun:
"Of more than 25,000 images, only these seven can vaguely find traces of the God King."
Xu Yun took it and put it in his palm to read.
The folded document that Gauss handed him has been temporarily revised into a simple booklet. A red circle has been drawn on a certain position on each page. A particularly small light can be vaguely seen in the red circle. point.
At the same time, Gauss was supplementing the explanation of the screening principle:
"After we deduced the trajectory of King God through the planet's orbit and other data, we used the true approximation angle to infer its theoretical position."
"That is, where it should appear on a certain day of the month, and which observatory will theoretically record it, and then look for the observation records of that day."
"It's just that King God is too far away from the earth, and it is very difficult to observe it even with the Schmidt telescope."
"At the same time, it is impossible for the observatory to just happen to photograph that star area on the corresponding day, so it is not easy to search. In the end, only these seven images were found."
Xu Yun nodded with understanding.
Mentioned earlier.
There is an empirical formula for the aperture of the telescope, which can easily calculate the limit magnitude ml of the telescope.
The formula is ml=2.1+5lgD.
where D is the diameter of the telescope in millimeters, and lg is the logarithm.
For example, Sedna's apparent magnitude is +18.9. As long as you find the right location, you can find it later with a 9.25-inch Schmidt-Cassegrain telescope and CCD camera.
The brightness of King God must be lower than that of Sedna, but the diameter of the telescopes at observatories in various places in 1851 was far beyond the equipment of ordinary astronomy enthusiasts in later generations.
At the same time, 200 astronomical units are converted into light years, which is equal to about 0.00316.
It is said that it is in orbit outside the solar system, but in fact it is near the checkpoint at the highway intersection.
Coupled with the principle of Schmidt telescope, no matter how far away the King of God is, it is not difficult to simply see it.
Still the same sentence.
It's easy to simply see a star, but because it's stationary, it's hard to tell whether it's a star or a planet.
The topic returns to its original place.
Although now with the assistance of the Schmidt telescope, the observation capabilities of major observatories have been greatly improved.
But the problem is that the recording method of the observatory these days is relatively primitive, and the camera can only be attached to the main mirror of the telescope to focus and take pictures.
If the camera shakes slightly or encounters other interference, the captured images will be blurry.
In addition, the universe is so vast that each observatory can only take three or four photos per day.
Therefore, when the viewing distance is enlarged, they can capture very little content - specifically, you can take out your mobile phone, adjust the focus to the maximum and then try taking a picture of the sky. Three or four pictures can only cover a very small area. an area.
To put it bluntly, this is using the exhaustive method to draw a lottery.
Therefore, when Gauss and others were looking for observation records corresponding to the date, the above situation occurred:
For example, what he needed were photos from the southwest on June 23, but the records taken by the observatory were from the northeast.
But if you don't zoom in on the overall picture, you can't see the King of Gods - this is equivalent to observing with the naked eye.
So get through it.
Gauss and the others only found seven photos, which was only seven more than the fishing guy's manuscript.
Then, under the guidance of Gauss, Xu Yun came to the Tatara telescope.
"Ascending Node Longitude 67.223"
"Orbital eccentricity 0.38273747"
Xu Yun started to slowly adjust the telescope according to the relevant data given by Gauss.
The finderscope still locks the star area, and adjusts the image in the center of the main mirror to the center of the finderscope's crosshairs as much as possible. .
Wait until the optical axes of the two lens tubes are parallel.
Xu Yun turned the tripod and made the final focus.
About five minutes passed.
In Xu Yun's field of vision, a tiny but vaguely bright dot appeared.
And the same as Pluto.
There is almost no interference from other celestial bodies around this small dot. Just like the God King Odin in Norse mythology, he is sitting alone at the other end of the galaxy, looking at this land in the ice and snow.
Look at the little dots in your field of vision.
Xu Yun frowned again.
He has observed Sedna and Eris many times. Judging from Xu Yun's experience, the visual magnitude of God King is probably around +25.
Maybe even closer to +26.
The higher the apparent magnitude, the harder it is to see, and the negative magnitude is as bright as Saitama's bald head.
For example, the apparent magnitude of the Sun is -26.7.
The SN1006 supernova explosion that Lao Su saw originally had an apparent magnitude of about -7.5.
The limiting visual magnitude that non-space telescopes can see is about 25 to 26, and Hubble's limiting visual magnitude is 30.
But on the other hand.
A considerable part of the limit visual magnitude of non-space telescopes is affected by atmospheric pollution.
The pollution here does not refer to industrial pollution in a certain area, but to the overall industrial pollution level of mankind for hundreds of years.
Therefore, in 1851, it was normal for Xu Yun to use the Tatara telescope to see celestial objects of visual magnitude +26.
+26ah.
Think of this.
Xu Yun's little heart suddenly started beating loudly again.
According to his original guess.
If the mysterious Planet
Of course.
The calculation here does not refer to Gauss in 1850, but to the theoretical value calculated by later simulated orbital equations.
At the same time.
There is another ratio between the diameter of the planet and the albedo of the planet, which can determine the apparent magnitude.
The maximum albedo is 1, and the minimum can be as small as the limit, but generally the minimum is a few percent.
Therefore, even if calculated based on the albedo of Eris, Sedna, etc., the visual magnitude of God King should not be too low.
And now its properties violate this ‘common sense’.
Think of this.
A word suddenly appeared in Xu Yun's mind:
Faint celestial body.
Faint objects refer to stars that are close to or exceed 30 visual magnitudes.
These celestial bodies also formed some dim galaxies in the universe, called dim galaxies.
Most of these dim galaxies were the first to form in the universe
First generation galaxies.
Among the more representative ones are Segue-1, BootesI, TucanaII, UrsaMajorI, etc., all around the Milky Way.
These galaxies are all over 13 billion years old, and the current known age of the universe is 13.82 billion years old.
These galaxies are also supported by a later argument called the ‘cold dark matter’ model, which is the framework system of non-baryon dark matter.
Such as axions and so on.
However, the large-scale axion verification experiment at the end of 2020 finally obtained zero results, which means that even if axions exist, they are more difficult to detect than predicted in the past. Therefore, many scholars now have little confidence in the existence of axions.
And if this god king is a dim celestial body
Although its age cannot be compared with other faint celestial bodies, is it possible that it can record some other ancient information?
After all
The distance between God and King is really too far.
Generally speaking.
Initially all stars formed from a pre-star nebula that pulled matter in.
The outer regions remain cold, where amorphous silicates, carbon-based compounds and ice accumulate.
Once the prestellar nebula forms a protostar and then a mature star, this outer material moves in and begins to form clumps.
over time.
These clusters begin to interact, merge, migrate, and potentially pop up another cluster.
These clusters are planets.
But if the planet is extremely far away.
Some information from earlier periods may not enter the standard orbits of the eight planets, but will be 'adsorbed' to the King of Gods.
The observation methods of later generations may be different from those of 1850. If there is a dim star or quasi-dimmish star in the solar system
Almost in just a few seconds, Xu Yun made a decision:
The existence of the God King must be reported as soon as possible after returning to the dungeon!
As for how it will be handled or whether it will be 'shared', this is not something he can guess or decide.
But as we all know, rabbits are very vindictive.
For example, the eagles successfully landed on the moon in 1969, but it was not until 1978 that they sent us a piece of lunar soil.
At that time, Academician Ouyang Ziyuan was still at the Institute of Geochemistry. One day, he suddenly received a call from the institute, saying that the institute was organizing a research team to study moon rocks and asked him to return to the institute quickly.
Academician Ouyang got on his bicycle and rode back to the institute. Before he could catch his breath, he saw the piece of moon rock placed in the middle of the hall.
That piece of moon rock looked really big. At that time, Academician Ouyang had already begun to imagine how many pieces the stone could be divided into and what experiments would be done on each piece...
After careful study, I discovered that the eagle was not that generous after all:
They used a convex lens to make a glass cover and placed it outside the moon rock, so it seemed to be magnified many times.
How big is this moon rock actually?
1g.
Well, 1 gram.
And even this 1 gram of moon rock was not used for research at that time. It was divided into two halves, one half of 0.5 grams, and it is still on display in the Yanjing Planetarium (yes, we also followed the example of the eagle and put a piece on the stone) Magnifying glass, if you are interested, you can take a look if you have the opportunity).
Similar 'friendly actions' have happened countless times even in the astronomical field.
What is more recent is the data from the New Horizons spacecraft that flew by Pluto. Now the eagle is still covering it tightly and only shows it to a few dogs at home.
Therefore, Xu Yun was sure that his superiors would give him the same gift in return.
Reciprocity is a courtesy.
Although the rabbit looks pink and tender on the outside, it is black when cut into pieces
And just when Xu Yun was in high spirits.
Bang——
Suddenly there was a dull loud sound in his ears.
Xu Yun subconsciously turned his head and looked in the direction of the sound.
I only see this moment.
Not far from his side, Prince Albert's side.
The stressed-out man named Wilshere Kennedy who he had seen earlier in the parking lot, who looked very happy, was now lying on the ground, with a pool of blood flowing out near his head.
A few seconds later.
A male voice with at least the key of C3 suddenly sounded, resounding throughout the open space:
"No, there are assassins!!!! Protect Your Majesty quickly!!!!"
As soon as this statement came out.
There was an extremely brief silence in the clearing.
In less than half a second, the silence turned into a series of frightened shouts:
"Gun! There is a gun!!!"
"Run quickly——"
"Yeah"
Bang bang bang——
While talking.
Several more gunshots rang out around them, and people fell to the ground one after another.
Maybe it's because we live in peaceful times.
It wasn't until the second gunshot that Xu Yun recovered from his shock.
After coming back to his senses.
The first thought that appeared in his mind was.
How is this possible?
How could there be gunshots in Cambridge University tonight?
firearms.
This is a very charming weapon, but its development process is also very tortuous.
The first generation of firearms was called a gun.
Everyone is familiar with this stuff. It existed in the Song Dynasty and reached its peak in the Ming Dynasty.
In addition to bows and arrows, the cavalrymen of the late Ming Dynasty loved three-eyed muskets the most.
As of the 1960s, some local militias even continued to be equipped with firecrackers.
Its disadvantage is that it can only be fired almost once in actual combat, and its shooting accuracy is very low.
The advantage is that it can continue to be used as an iron rod after being beaten.
After the musket came the matchlock, and then the flintlock musket from the 16th to 17th centuries.
By the end of the 19th century, the prototype of modern firearms was born:
That is a combination of breech-loading gun + polygonal rifling + smokeless powder + conical warhead.
But just like in later generations, countries have different levels of weapons development and rarely share technology.
At the end of the nineteenth century, the development levels of firearms in various countries were also different.
Take Britain in 1851 as an example.
Polygonal rifling would not appear until 1854, so muzzleloaders and even flintlock muskets are currently commonly used in Britain.
The most elite troops are equipped with a weapon called the 'Mine Rifle'.
This gun has a caliber of 17.83mm, a barrel length of 990mm, four riflings, and a twist rate of 1:78.
The barrel is fixed to the full-length walnut stock by three bolts. The bottom plate of the stock is made of brass and the total length is 1397mm.
Although this kind of firearm has a certain degree of lethality, its firing accuracy and range are both big problems.
For example, its theoretical range is 183 meters, but its effective range is only about 100 meters.
This value is roughly the distance from the auditorium to the analysis machine shed.
In other words, the shooter's location must be within the venue.
But the problem is
Prince Albert's appearance at the experiment site today was not an impromptu event, but a pre-arranged itinerary - firstly, to support Xu Yun, and secondly, because Prince Albert is the president of Cambridge University, so he is in love. Yu Li cannot be absent.
So before starting the experiment.
All guests' vehicles must pass through a joint inspection by Cambridge University rangers and royal guards before they can be put into the campus.
In this case.
So much gunfire in the bowels of Trinity College?
Are you kidding me?
However, no matter how many questions Xu Yun had in his mind, there was a situation that was clearly before him:
The joke came true.
Seeing that the situation around him was getting more and more chaotic, he could only hear the sound of gunfire but could not see the enemy.
Xu Yun quickly protected Gauss and shouted to those around him:
"Mr. Thomson, you are optimistic about wheat!"
"Classmate Airy, take Mr. Airy with us!"
"Classmate Riemann, Mr. Faraday leaves it to you!"
"Everyone hide in the auditorium together, hurry up!"
Finished.
Xu Yun protected Gauss with one hand, and subconsciously prepared to pull Aveline with the other hand:
"Also Aveline, we...eh? Aveline?!"
Xu Yun's left hand scratched randomly in the air a few times, but couldn't catch anything.
He turned his head in surprise.
I only saw my left hand side
Empty. (End of chapter)
