When human beings walked out of the earth, they first saw the vast solar system, and in the solar system, in addition to the eight planets, there are countless asteroids and other small celestial bodies. A large number of asteroids enter the inner galaxy from the edge of the solar system, posing a threat to the stability of the inner galaxy. Fortunately, there is a huge Jupiter in front of it. Most of the asteroids are attracted by Jupiter’s gravitational force, or crash on the surface of Jupiter, or Become a moon of Jupiter.
As humans’ cognition of the universe has not improved, we know that there is even more vast interstellar space outside the solar system, but because humans’ technological strength is still very weak, they have no ability to truly go out of the solar system to explore the mysteries of outer space. At this time, people are expecting that celestial bodies outside the solar system can enter the solar system, so that we can learn some secrets of the outer space through this celestial body.
Perhaps the cosmic consciousness has heard the call and expectation of human beings. On October 19, 2017, scientists discovered that a cigar-shaped asteroid entered the solar system from the direction of Lyra. This asteroid is very different from the asteroids we usually see. It is not a sphere, but a long strip, about 400 meters in length and about meters in width, and the color is also very unique, showing red.
Such a unique asteroid enters the solar system from the direction of Lyra at a speed of 26 kilometers per second. This is a very fast speed. Such an “interstellar traveler” came to the solar system and made scientists very excited. The call of mankind has finally been answered. The entry of an external celestial body is of great significance for us to understand the conditions of the solar system.
Although scientists are very much looking forward to this small celestial body, because it enters the solar system too fast, it is destined to be unable to stay in the solar system, and the solar system is just a foothold in its long journey. Scientists gave this “interstellar traveler” a nice name called Oumomo.
Because Omomo’s speed is too fast, human detectors can’t keep up to make close observations, and can only get a rough data through the astronomical telescope. As Omomo keeps getting closer to the earth, we can see its true colors more clearly. When scientists see this long exoplanet at close range, they are all surprised by its uniqueness.
Some scientists even believe that Aomomo may not be a celestial body, but a disguised alien civilization probe. Why is there such a conjecture? First of all, the shape of Oumomo is very special. We have to know that we have not seen such a standard long celestial body in the solar system. Although there are countless asteroids in the solar system, none of them are of this shape.
This long celestial body easily reminds people of the look of a spaceship. You must know that for interstellar voyages in the universe, a long spaceship is more suitable for space exploration than other shapes, and can achieve higher speed and lower resistance. The director of astronomy at Harvard University believes that Omomo may be an “artificially manufactured light sail vehicle.”
Secondly, the speed of Oumamo is also very strange. It entered the solar system at a speed of 26 kilometers per second, and after entering the solar system, its speed has also changed many times. When flying over the earth, its speed is about 58900 mph. . When you are close to the sun, the speed is obviously accelerated, and when you are far away from the sun, the speed will be greatly reduced. We have never seen this kind of celestial body that can accelerate and decelerate. Perhaps only technological creation can do it.
Finally, its solid surface is very peculiar. The color of this interstellar object is reddish, which is clearly different from other asteroids and comets. At present, we don’t know whether the composition of this solid surface is rock or metal. It is very unusual. What’s more unusual is that the interstellar object is very bright and has a reflectivity at least 10 times higher than that of a typical stony asteroid or comet. .
It is precisely because of Omomo’s unusual performance that some scientists speculate that it may be a detector, but it looks like a celestial body. For a powerful interstellar civilization, it is not difficult to make a detector that looks like a celestial body.
Of course, some people have also raised objections to this. If Omomo is a probe of an alien civilization, it will inevitably detect the existence of a civilized planet Earth as it enters the solar system. But why does it pass through the earth? , Did not stop for observation, but just passed quickly?
Many people think that it is because of this kind of thinking that Oumomo is unlikely to be a probe of alien civilization. It should be a special alien celestial body. Only when the celestial body passes by the earth, it will not stay but stay. forward. So when the probes of alien civilization pass the earth, will they stop to observe? It may not be necessary.
Let’s use Voyager 1 as an example. It is an interstellar probe launched by humans in 1977 with the purpose of moving forward outside the solar system. Imagine that if Voyager 1 goes smoothly on its journey, countless years later, it may also enter a galaxy with a living planet.
When Voyager 1 travels through this galaxy, will it stop when it passes by the planet of life? Of course not. The reason is very simple. Voyager 1 has no intelligence and limited energy. When it travels into interstellar space, it has already become a discarded product of mankind. Its faster and faster speed is only accelerated by the gravitational force of various celestial bodies. Brought.
Therefore, no matter how many galaxies and life planets it has passed through, Voyager 1 will only move forward without stopping to observe. In the same way, Aomomo may also be a “discarded product of alien civilization”. It may have set off from the parent planet of alien civilization a long time ago. When it sailed in interstellar space, it had already lost energy and became completely A space junk with no observation capability.
Of course, what is the true identity of Aomomo? At present, opinions are divided, and opinions are not uniform. Some people think that it is just a celestial fragment from a galaxy near the solar system, and there is nothing special about it. Some people also think that it is a disguised spacecraft of an alien civilization. It has already recorded information about the earth when it passes by the earth.
Others believe that it is just a deserted product of an alien civilization, a solar sail. Which statement is correct? Perhaps only the matter of the galaxy can find the answer. To achieve this, the current human technology cannot do it, and we need our technology to go further.
Fortunately, Aumamo will not leave the solar system anytime soon. Although it is very fast and can escape the shackles of the sun’s gravity, it will take at least 7500 years to pass through the Oort Cloud completely at this speed. Therefore, there is still hope for human beings to catch up with it. The speed of human science and technology development is very fast. It only took us about 200 years to achieve our current scientific and technological strength. Then we will give mankind thousands of years of development time to realize the initial interstellar space. Travel may also be promising.
As long as human beings have the initial interstellar travel ability and the speed of sublight flight, then it is very easy to catch up with Aumamo. As long as we can catch up with it and probe it in detail, it may not be difficult to reveal its mystery. If Omomo is really an interstellar probe, then its solid surface is likely to be metal, and it is not an ordinary metal. As long as we can determine that the material composition on its surface is metal, we can basically determine that it is an external Star civilization spacecraft or probe.
