Review
Almost every once in a while, the discussion of extraterrestrial civilizations will come back, setting off a hot discussion in human society, and the opportunity is the emergence of some mysterious objects, such as the development of astronomical observation technology in the last century, and the UFOs in the sky have also received more attention.
At the same time that the official can not give an explanation, the folk speculation about the alien civilization was once very loud, but because of the lack of iron evidence, so over time people will gradually forget these things, and in 2017, the appearance of a new skyline object has once again aroused the attention of the whole people, it is Ou Momo.
OuMuamua
The name Oumuamua was named by the International Astronomical Union, which originally meant a scout or messenger, which also gave a mysterious color to the existence of this celestial body, and Itoa was first captured by our instruments in October 2017.
According to the information given by the observation equipment, the diameter of this celestial body should be more than one hundred meters, from the appearance of a cigar, the length of about 400 meters, in the imaging as solid matter, the trajectory of the movement at that time is also very eye-catching, 26 kilometers of wonderful speed, almost can be said to rush into the solar system, this is also the first time so far, human beings have found that objects outside the solar system into our galaxy.
Theoretically, each galaxy itself has a relatively stable operating system, the most important driving force is the gravitational action between various celestial bodies, after billions of years of running-in and adaptation, has basically formed a very mature structure, can ensure its own a relatively independent existence.
This independence means that it will not be easily affected by extraterrestrial factors, which is also the premise that the earth can give birth to life and have a safe development environment, but the emergence of Oumuma has broken the tranquility that has been maintained for billions of years, and it is like an uninvited guest, forcibly knocking on the door of the solar system and entering the space where we live.
Of course, at present, it has not yet collided with any celestial body in the solar system, and when it entered the solar system, the direction did not change much, basically maintaining a perpendicular angle with the ecliptic plane, but the speed of operation was constantly accelerating, and after leaving the perihelion, the speed had increased to 40 kilometers per second.
Although we tried to predict the path after it by the trajectory of the first half, the final comparison showed that there was a large deviation between the actual trajectory of Oumuamua and our prediction.
That is to say, there are factors that are not yet mastered by astronomy, and in addition to the action of gravity, there are other external forces that determine the operation of this celestial body.
By October 2018, It has been a full year since Oumomo entered the solar system, at this time it has gone between Jupiter and Saturn on the other side, our equipment can no longer continue to observe, the calculation results predict that in about 4 years, Oumuamua will cross the orbit of Neptune, if there is no other situation, it is also an inevitable result of its departure from the solar system.
Alien civilizations
From the appearance of Aumimo to its departure, the most confusing thing for us is its trajectory, as far as the existing level of astrophysics is concerned, no matter what the source is, no matter how big or small, as long as the basic information is mastered, it should not be difficult to calculate the trajectory of an extraterrestrial object, but Aomomo has broken our prediction and run on another trajectory with a great error, which undoubtedly challenges our science.
There are only two reasons behind this, one is that Oumuamua has revealed a factor that we have not yet discovered, which can have a significant impact on the trajectory of celestial bodies in specific scenarios.
The other is the possibility that we dare not believe, but do not dare to completely deny, that is, the existence of extraterrestrial civilizations, and the more we analyze their trajectory, we tend to believe in the truth of this possibility.
As we mentioned above, the angle at which Oumuamua enters the solar system is basically perpendicular to the ecliptic plane, and there is almost no major change in the first half, but when it arrives near Jupiter from the orbit of Mercury, it takes a 90-degree turn, as if it suddenly encountered an obstacle here and was bounced out, and the first half and the second half were strangely symmetrical.
Even if there is something non-gravitational action outside of our cognition, it is not so obvious that it has not been captured by us, and the whole process looks more like a deliberate design, specifically using the gravitational force of the solar system to achieve the expected purpose of flight.
But from the appearance, Oumuamua is indeed just a rocky celestial body, and it is really difficult to associate with what spaceships and alien civilizations, of course, some views believe that this may be some kind of disguise, after all, Oumuamua and the various immortal bodies that have appeared before are indeed very different, and the shape alone is impressive.
The celestial bodies in the universe, regardless of their size, are almost all spherical or nearly spherical, but Oumuamua is presented as a long strip, and from all angles, it does not look like fragments that have fallen off from somewhere, but more like the alien spacecraft and manned rockets we see in science fiction works.
In addition, the change in the speed of Aomomo is also very strange, especially in the second half of the process of leaving the solar system, it began to accelerate abnormally, if it is a celestial body in its natural state, after such a long period of energy consumption, if not slowed down, at least at the original level, and it can obtain new power, it is really incredible.
epilogue
As far as the existing data is concerned, if a reasonable explanation for these anomalies can be found, we should be able to dispel the speculation that Oumuamua is an alien civilization, but if not, then it may become another big mystery in the history of astronomy.
