Imagine taking a walk on the beach. There are thousands of little stones on the ground. They are all different. Still, when you look from a distance, you can see that all of these are stones. Millions of stones created naturally. Then something in the distance draws your attention. Something that looks different than others. It is both brighter and very different in shape. Something thin long. Is this a naturally formed stone or an artificially produced object?
There is such a thing that has disturbed scientists for about 1.5 years. An unusual stone or object they encounter on the coast of space. It all started in Hawaii. There is an observatory on the top of the Haleakala volcano rising 3000 meters above sea level. One of the works of the PAN-STARRS telescope in the observatory is to detect celestial bodies passing by the earth. Such a celestial body was detected on October 19, 2017. But days after it was closest to the world. Because this object was moving very fast. It was moving so fast that it couldn’t be from our solar system. It was the first time that an interstellar celestial body was detected. This object, which is unknown where it came from and where it went, was called “Oumuamua”. In Hawaiian, this word means “Explorer, ambassador or pioneer unit”.
This object, initially considered a comet, was reclassified a week later as an asteroid. However, it was also said that it may be an artificial object, not a natural one, due to some features that have never been observed so far. Moreover, it is not conspiracy theorists who say this. Avi Loeb, a professor of theoretical physics at Harvard University, based on Oumuamua’s “strange acceleration” in a scientific article he published about this object. expression to He gave the place: “This object may be a fully functional alien spaceship sent around the world by deliberately civilization.”
Science Fiction writer Arthur C. Clarke wrote a novel called “Meeting with Rama” in 1973. In this novel, which took place in 2131, astronomers discover a mysterious celestial body and classify it as an asteroid. But by looking at the movements of this object, which they call Rama, they realize that it has an unusual orbit. So it came from outside the solar system. They send a spaceship for a closer look, and it turns out that the shape of Rama is like a cylinder from the photos that the ship sent. On top of it, they realize that this is a spaceship.
Due to the similarity between the mysterious figure found and this story, some have called this celestial body Rama. However, we were unable to take a picture of this object, as we could not send a spaceship for inspection. For about 1.5 months, we only have observations made with different telescopes of the world. According to these, we know that it is close to metal in red color and completes its rotation in 7.5 – 8 hours. Based on the change in its brightness, it was concluded that it should be like a bar measuring approximately 80 meters by 800 meters. In other words, it was thought that it might be covered with carbon-rich substances due to its Red color like a cylinder. One of the most surprising features of scientists was that it gradually increased its speed. We can see this kind of movement in comets in our solar system. As a result of the heating of the substances with sunlight, a gas outlet occurs and this leads to a rocket effect. The tail we see is this gas outlet. However, there has never been such a gas outlet in Oumuamua. Could it be a comet without a tail? Oh, no. That’s why they decided to call it an asteroid. But asteroids can’t change their speed either. In addition, their brightness varies no more than 1 to 3, not 1 to 10. Already, comets usually come from the OORT cloud, and the asteroids come from the asteroid belt between Mars and Jupiter, and these two sources are part of our solar system, and therefore their speed is compatible. The found object moves very fast in a hyperbolic orbit and gradually increases its speed. Scientists say there may be one more thing that can lead to this strange acceleration. A sail of 0.3 meters thin, 20 meters in diameter.
New released in November 2018 Accordingone article to, “solar radiation pressure” may be the reason for acceleration. If this celestial body is not natural but artificial, it may be using some kind of sail to accelerate using this pressure. Our civilization in projects such as IKAROS and Starshot As we can see , he managed to design such sails. Because this is one of the most suitable technologies to be used in interplanetary or interstellar transportation.
So there is a pen-like object coming from outside our solar system, and this object, which is already very fast, is increasing its speed gradually. According to this article, this may be due to a paper-like sail in front of him. A pencil drawn in front of the paper!
Scientists who wrote this article do not find it speculative for two reasons. First, if we exist and can imagine such technologies, why not others? Second, we estimate that at least a quarter of the star systems in the Milky Way Galaxy are a Earth-like planet. So there is the possibility of life on billions of planets. Although one of these planets has completely lost the creatures currently in it, it may have sent such spacecraft all over the galaxy in time. As we sent the Voyager 1 and Voyager 2 vehicles.
The biggest feature of the vehicles we send is to send the data they find back to us via radio signals. If Oumuamua is such a means of discovery, it must also be communicating with its home in some way. Indeed, the “Breakthrough Listen” project, which explores the forms of extraterrestrial life, immediately started listening to this object. But he couldn’t hear anything. This strange object was completely silent. Either it communicates in a quantum world method that we don’t know yet, or there’s no need to force it, it’s not a spacecraft.
Today we have completely lost track of this object. Most scientists believe that it is a very exceptional object, but natural. However, it has not been scientifically proven that it is not artificial.
“Regardless, we believe it is a natural object. But we cannot prove that it is not artificial. ”
What everyone has an idea of is that it is the first and only object we can observe from outside our solar system. In this sense, he really is a pioneer like his name. It is a very different stone than the stones we see while walking on the beach. What would he do if the person walking on the beach was not a us but a cave man who lived thousands of years ago and saw such a different stone? For example, if he found a cell phone with a dead battery. Would it classify it as a stone different from other stones but still? Or would he have imagined it as a stone-made tool of a tribe that he had never thought of, according to his own technology. Whatever he does, there is no way to tell the man what kind of technological product a cell phone really is. If we encounter a more advanced civilization than us one day, we will either not notice it or try to describe it according to our own technologies. Most likely we will never be able to fully understand what it really is. Nevertheless, even the idea of finding a bottle with a message while strolling on the beach is enough to excite people.
