Into Unscientific Chapter 340

  Chapter 340 Goodbye, 1850! (five)

  Looking at the light curtain in front of him.

  Xu Yun's heart suddenly thumped violently!

  If it is said that Gaussian calculation process may still have some possibility of errors and omissions, resulting in misjudgment of the final result.

  Then the emergence of the halo prompt is undoubtedly an affirmation from the rule level:

   They really found the mysterious planet X!

   Or rather.

   Planet Nine!

   And the light curtain that appeared in front of him also represented that Xu Yun could raise his hands to the sky and shout "I'm done with the mission".

   But at this moment.

  He didn't have the slightest intention to do so.

after all

  The jumping countdown reminds him of one thing all the time—

  He can stay in the dungeon as 'Luo Feng', or in 1851

   is running out.

  Wheat, Lao Tang, Aveline, Faraday, Gauss, Riemann, Kirchhoff, Axe.

   After four hours, I will bid farewell to him forever.

   Fortunately, Xu Yun has experienced the separation of dungeons in 1100 years, and he is already prepared for this kind of separation.

  In addition to the fact that his acquaintances are basically on the scene tonight, four hours is enough to do some things.

  So Xu Yun forced himself to calm down, and turned his attention to Planet X in front of him again.

   After all, Planet X still has a lot of links to deal with.

  I saw him thinking for a moment, raised his head, and said to Gauss:

   "Professor Gauss, I think the name God King is pretty good—but there are a lot of God Kings in Europe. Which one do you plan to use as its alias?"

  Readers who have done European gods in their previous life should know.

   In ancient European mythology.

  There are a total of six characters known as the "God King" level, and the Greek and Nordic myths are divided into half.

  The three generations of god-kings in Greek mythology are:

   Uranus, Cronus and Zeus.

   Among them, Cronus is the youngest son of Uranus, and Zeus is the youngest son of Cronus.

  Uranus was the first **** to rule the universe, and was later overthrown by Cronus.

  Cronus was the second **** to rule the universe, and was later overthrown by Zeus, and Zeus became the third **** to rule the universe.

  True, loving father and filial son.

  The three generations of god-kings in Nordic mythology are:

   Bully, Paul, Odin.

   Ended in 1851.

  Uranus was given the alias of Uranus.

  Cronus is the name of Saturn.

  Zeus is the name of Jupiter.

  Therefore, there are only three generations of god-kings in Norse mythology left for Gauss to be aliased.

Of course.

   It is not impossible to name Gauss after Gauss. After all, Gauss can be regarded as the king of mathematics, but then he will become the king of Gauss

   "Alias"

   Hearing Xu Yun's words, Gauss thought for a while, and quickly gave the answer:

   "Let's call it Odin."

  Hearing this, Xu Yun's pupils shrank imperceptibly.

Is this a coincidence?

   Mentioned earlier.

  The supercomputer of the general formula of ring system celestial bodies derived by the later BSC is also called Odin

   Then Xu Yun coughed lightly, trying to make his expression look normal.

   Continue to ask Gauss:

   "Professor Gauss, can you let me see the observation records of God King?"

  Gauss nodded, picked up a stack of thin documents from the operating table, and handed them to Xu Yun:

   "Of the more than 25,000 images, only these seven images can vaguely find the traces of God King."

  Xu Yun took it along with the opportunity, and looked at it in the palm of his hand.

The folded document that Gauss gave him has been temporarily revised into a simple booklet. A red circle is drawn on a certain position on each page, and a particularly small light can be vaguely seen inside the red circle. point.

   At the same time, Gauss is supplementing the explanation of the screening principle:

   "After we deduced the trajectory of Neptune through planetary orbits and other data, we deduced its theoretical position using the true approximation angle."

   "That is, where it should appear on a certain date on a certain month, which observatory will theoretically record it, and then go to find the observation records of that day."

   "It's just that Shenwang is too far away from the earth, and even the Schmidt telescope is very difficult to observe."

   "At the same time, it is impossible for the observatory to take pictures of that star area on the corresponding day so coincidentally, so it is not easy to search, and in the end we can only find these seven images."

  Xu Yun nodded in 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.

  This formula is ml=2.1+5lgD.

   Among them, D is the value of the aperture of the telescope in millimeters, and lg is the logarithm.

  For example, the apparent magnitude of Sedna is +18.9. As long as you find the right position, later generations can find it with a 9.25-inch Schmidt-Cassegrain telescope and a CCD camera.

  The brightness of Neptune must be lower than that of Sedna, but in 1851, the caliber of telescopes in various observatories was far from comparable to that of ordinary astronomers 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 the orbit outside the solar system, but it is actually near the checkpoint at the highway intersection.

  Combined with the principle assistance of the Schmidt telescope, no matter how far the distance of Neptune is, it is not difficult to simply want to see it.

Again.

   It is very easy to simply see a star, but because it is still, it is difficult for you to tell whether it is a star or a planet.

  The topic returns to the 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 is relatively primitive these days, and the camera can only be attached to the main mirror of the telescope to focus and shoot.

   If the camera shakes slightly or encounters other disturbances, the captured image will be blurred.

  Combined with the vastness and boundlessness of the universe, each observatory can only take three or four photos every day.

Therefore, in the case of zooming in on the viewing distance, there is very little content they can capture—specifically, you can take out your mobile phone, adjust the focal length to the maximum, and then try to take pictures of the sky. Three or four shots can only cover very small areas an area.

   To put it bluntly, this is using the exhaustive method to draw a lottery.

  So when Gauss and others were looking for the observation records of the corresponding date, the above situation appeared:

  For example, what he needs is a photo from the southwest on June 23, but the record taken by the observatory is from the northeast.

   If you don't zoom in on the panoramic picture, you won't be able to see God King—this is equivalent to observing with the naked eye.

   So one pass down.

  Gauss and the others only found seven photos, seven more than the fisherman's manuscript.

   Then, under the guidance of Gauss, Xu Yun came to the side of the Duodoluo telescope.

   "Ascending node longitude 67.223"

   "Orbit eccentricity 0.38273747"

  Xu Yun started to adjust the telescope slowly according to the relevant data given by Gauss.

  The finderscope is still locked to the star area, and the image in the center of the main mirror is adjusted to the center of the crosshairs of the finderscope as much as possible. .

   Wait until the optical axes of the two lens tubes are parallel.

  Xu Yun turned the tripod for the final focus.

  After about five minutes or so.

  In Xu Yun's field of vision, a faint but faintly bright dot appeared.

   And the same as Pluto.

  There is almost no interference from other celestial bodies around this small point, just like Odin, the **** king of Norse mythology, sitting alone at the other end of the galaxy, looking at the land in the snow and ice.

   Look at the dot in the field of vision.

  Xu Yun frowned again.

  He has observed Sedna and Eris many times, judging from Xu Yun's experience, the apparent magnitude of Shenwang 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 big bald head.

  For example, the apparent magnitude of the sun is -26.7.

  The SN1006 supernova explosion that Lao Su saw at the beginning had an apparent magnitude of around -7.5.

  The limit star magnitude that can be seen by non-space telescopes is about 25 to 26 magnitudes, and the limit star magnitude of Hubble is 30.

   But on the other hand.

  The limit apparent magnitude of non-space telescopes is largely affected by atmospheric pollution.

  The pollution here does not refer to the industrial pollution in a certain area, but the pollution level of the overall human industry for hundreds of years.

   Therefore, in 1851, it was normal for Xu Yun to be able to see celestial objects with an apparent magnitude of around +26 with the help of the Dodoluo telescope.

  +26 ah.

  Think here.

  Xu Yun's little heart suddenly started beating again.

  According to his original guess.

   Even if the mysterious X-planet, Shenwang, really exists, its apparent magnitude will probably not be lower than +20—because the diameter of Shenwang can be calculated in advance, it must be several times that of the earth.

Of course.

  The calculation here does not refer to Gauss in 1850, but the theoretical value calculated by the simulated orbital equation in later generations.

   At the same time.

   There is also a 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 lowest is a few percent.

   Therefore, even if it is calculated according to the albedo of Eris, Sedna, etc., the apparent magnitude of Shenwang should not be too low.

   And right now its nature violates this 'common sense'.

  Think here.

  A word suddenly appeared in Xu Yun's mind:

   Dim celestial body.

  Dim celestial objects refer to stars close to or over 30 magnitude.

  These celestial bodies also form some dark galaxies in the universe, called dim galaxies.

  And most of these dim galaxies are the earliest formed in the universe

  Generation 1 galaxy.

   Among them, Segue-1, BootesI, TucanaII, and UrsaMajorI are more representative, all of which are around the Milky Way.

  The age of these galaxies is more than 13 billion years old, and the age of the known universe is 13.82 billion years old.

  These galaxies are also the argument support of a model called "cold dark matter" in later generations, that is, the frame 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 got zero results, which means that even if axions exist, they are more difficult to detect than predicted in the past. Therefore, quite a few scholars now have no confidence in the existence of axions.

   And if this **** king planet is a dim celestial body

  It is true that its age cannot be compared with other dim celestial bodies, but is it possible for it to record other ancient information?

after all

  The distance of God King is too far.

  Generally speaking.

  Initially all stars formed from a pre-star forming nebula that drew matter into it.

  The outer regions are still cold, where amorphous silicates, carbon-based compounds, and ice all collect.

  Once the prestellar nebula forms a protostar and then a mature star, this outer layer comes in and starts to form clumps.

Over time.

   These clusters begin to interact, merge, migrate, and potentially pop another cluster.

   These clusters are the planets.

   But if the planet is extremely far away.

   Some information from earlier periods may not enter the standard orbit of the eight major planets, but will be 'adsorbed' on Shenwang.

  The observation methods of later generations may be different from those in 1850, if there is a faint star or a faint star in the solar system

  In just a few seconds, Xu Yun made a decision:

  The existence of the king of gods must be reported as soon as possible after returning to the copy!

   As for how the above will handle it or whether it will be 'shared', this is not something he can guess or decide.

   It's just that rabbits are known to hold grudges.

   Like 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 immediately.

  Academician Ouyang got on his bicycle and rode back to the institute. Before he could catch his breath, he saw the moon rock in the middle of the hall.

   That moon rock looked really big. Academician Ouyang had already started to imagine how many pieces this rock could be divided into, and what experiment each piece could do...

   As a result, after careful study, it was discovered that the eagle is not so generous at all:

  They made a glass cover with a convex lens and put it outside the moon rock, so it looks magnified many times.

  How big is this moon rock actually?

1 g.

   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 imitated the eagle and put a piece on the rock. Magnifying glass, if you are interested, you can take a look if you have the opportunity).

  Similar 'friendly acts' have happened countless times even in the field of astronomy.

  Recently, there is also the data of the "New Horizons" flying over Pluto. Now the eagle is still tightly covered, and only a few dogs at home can see it.

   Therefore, Xu Yun is sure that his superiors will give the same gift in return.

   Reciprocity.

   Don't look at the pink and tender appearance of the rabbit, it's all black when cut open

   And just when Xu Yun's mood was soaring.

  Boom—

  Suddenly there was a dull loud noise in his ear.

  Xu Yun subconsciously turned his head and looked in the direction of the voice.

  I saw this moment.

   Not far from him, Prince Albert's side.

  The stressful old man named Wilshere Kennedy whom he had seen in the parking lot earlier, who looked very happy, was now lying on the ground with a pool of blood flowing out near his head.

   After a few seconds.

  A male voice with at least C3 key suddenly sounded, resounding through the open space:

   "No, there are assassins!!! Hurry up and protect His Majesty!!"

  As soon as this remark came out.

   There was an extremely brief silence in the open space.

   In less than half a second, the silence turned into horrified shouts:

   "Guns! There are guns!!"

   "Run—"

   "Yeah baa"

   bang bang bang—

   Between speaking.

   There were several gunshots around, and people fell to the ground one after another.

  Maybe it's because we live in a peaceful age.

   It wasn't until the second gunshot that Xu Yun recovered from his astonishment.

   After regaining consciousness.

  The first thought that popped into his head was.

how can that be?

  How could there be gunshots in Cambridge University tonight?

   Firearms.

   This is a very charming weapon, but the development process is also very tortuous.

  The first generation of firearms is called firearms.

   Everyone is familiar with this thing. It existed in the Song Dynasty and flourished in the Ming Dynasty.

  In addition to bows and arrows, the cavalry in the late Ming Dynasty liked the three-eyed blunderbuss most.

   As of the 1960s, some local militias even continued to be equipped with firecrackers.

  His disadvantage is that it can only be fired almost once in actual combat, and the shooting accuracy is very low.

  The advantage is that it can continue to be used as an iron rod after the fight.

  Following the musket were the arquebus, and then the flintlock from the 16th to the 17th centuries.

  By the end of the nineteenth century, the prototype of modern firearms was born:

   That is the combination of breech-loading gun + polygonal rifling + smokeless powder + conical warhead.

  But just like the development of weapons in various countries in later generations has different levels and rarely shares technology.

   At the end of the nineteenth century, the development level of firearms in various countries was also different.

  Take Britain in 1851 as an example.

  Polygonal rifling will not appear until 1854, so muzzle rifles or even flintlock guns are commonly used in Britain at present.

  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 rifling lines, and a twist ratio of 1:78.

  The barrel is fixed on the full-length walnut wood **** by three bolts. The bottom plate of the buttstock is made of brass, with a total length of 1397mm.

  Although this kind of firearm has a certain 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 almost the distance from the auditorium to the analysis machine shed.

  That is to say, the location of the shooter must be within the field.

  But the problem is

Prince Albert's appearance at the experiment site today was not a temporary idea, but a pre-arranged itinerary—one was to support Xu Yun, and the other was that Prince Albert was the principal of Cambridge University. Reason cannot be absent.

   So before the experiment started.

  All guest vehicles must pass through a joint inspection checkpoint by Cambridge University rangers and royal guards before they can be put into the campus.

In this situation.

  There were so many gunshots in the hinterland of Trinity College?

  Are you kidding me?

  However, no matter how many doubts Xu Yun had in his mind, there was a real situation in front of him at this moment:

   The joke came true.

  Seeing that the surrounding situation is getting more and more chaotic, you can only hear gunshots but cannot see the enemy.

  Xu Yun hurriedly protected Gauss, and at the same time shouted to the surroundings:

   "Mr. Thomson, you are optimistic about wheat!"

   "Student Airy, you bring Mr. Airy with us!"

   "Student Riemann, Mr. Faraday gave it to you!"

   "Everyone hide in the auditorium together, hurry up!"

   Finished speaking.

  Xu Yun protects Gauss with one hand, and subconsciously prepares to pull Aveline with the other hand:

   "Also Avelyn, we. Huh? Avelyn?!"

   Xu Yun's left hand scratched the air a few times, but nothing was caught.

  He turned his head in astonishment.

  I saw my left hand side

   Empty.
