Do you believe in the existence of aliens? Have you ever seen a flying object (UFO)? Have you ever wondered if aliens are behind everything on Earth?
These questions may make many people curious and may also frighten many people. After all, we still know too much about the universe, and we still know too little about extraterrestrial life.
However, some scientists believe that aliens are not only real, but also secretly affecting the development of Earth. They even suspect that the solar system is a "petri dish" created by aliens for experimentation, and we are their "guinea pigs".
Doesn't that sound ridiculous? However, scientists are not making up their minds, but there is some evidence and reasons to support their views. Below, we take a look at how they came to this conclusion and what "anomalies" they found in the solar system.
Three "anomalies" in the solar system
First of all, we need to know that the solar system is a celestial system composed of a star (the sun) and eight planets (Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune) and many asteroids, comets, moons, etc. This system is not unique in the universe, there are many other similar star systems.
So, what's so special about the solar system? Why do scientists think it's being manipulated by aliens?
The answer lies in three "anomalies" in the solar system, which make the solar system very different from other star systems and make the Earth a very suitable place for the existence and development of life.
Anomaly one: water on Earth
We all know that water is the source of life, and without water there is no life. No living thing on Earth is separated from water, and most life on Earth originated in the oceans. The ocean is the cradle of all life on Earth.
So, where does the water on Earth come from? Why is there no water on other planets?
This was the first anomaly that scientists found. According to their exploration and research on other planets in the solar system (such as Mars, Venus, etc.), there is basically no liquid water on these planets. Therefore, they all look very barren and dry.
But the Earth is different, the area of the ocean on the earth accounts for about 70%, and the ocean also contains a lot of salt and minerals. These substances have played an important role in the formation and evolution of life.
It stands to reason that all planets in the solar system should be subject to the same or similar conditions and influences during their formation and evolution. But why is it that only the Earth can have such abundant and unique water resources?
Scientists have come up with different hypotheses, but none of them have received conclusive evidence and explanations. Some people say that the "dirty snowball" in the universe, that is, the comet, is brought by the comet, because the earth should have been surrounded by meteor showers after its birth, so there is so much water. But in that case, why haven't other planets been brought with water by meteor showers?
Some people say that this water should be brought by the earth, because the earth contains a lot of hydrogen and oxygen when it is formed, and these two elements will form water under high temperature and pressure. But in that case, why don't other planets form water?
In short, water on Earth is a big mystery and a lot of luck. Without water, there would be no life on Earth and no us.
Anomaly two: the position and distribution of the planets
Second, we'll look at the location and distribution of the planets in the solar system. This is also the second anomaly that scientists have found.
We all know that the planets in the solar system orbit the sun, and the closer the planet to the sun orbits faster, the farther away from the sun orbits slower. This is due to the gravitational action of the Sun on the planets.
So, what effect does the distance of the planets from the sun have on life?
The answer is very important. Because the distance from the sun determines the temperature and light on the planet. If you get too close to the sun, the planet will overheat, the water will evaporate, and the climate will be extreme. If you are too far from the sun, the planet will be too cold, the water will freeze, and the climate will be cold.
Therefore, for life to exist and develop, planets must be within a moderate distance, called the habitable zone. Planets in the habitable zone are neither overheated nor too cold, and maintain the right temperature and light for water and life.
So, which planets in the solar system are in the habitable zone?
The answer is that there is only one Earth. Other planets are either too close or too far away for life.
That's weird. Why is only the Earth in its sweet spot? Why are other planets deviating from the habitable zone?
Scientists have also proposed different hypotheses, but none of them have received conclusive evidence and explanations. Some say that the orbits of various planets changed due to huge collisions and disturbances in the early solar system. But in that case, why is only the Earth stable?
Some say that it is due to the important gravitational effect of giant gas planets such as Jupiter on other planets, affecting their orbits and motions. But in that case, why aren't giant gas planets such as Jupiter affected themselves?
In short, the location and distribution of the earth is also a big mystery and a great luck. Without such a location and distribution, there would be no suitable temperature and light on Earth, and there would be no us.
Anomaly three: Oort cloud
Next, we'll look at a mysterious structure in the outer solar system, the Oort Cloud. This is also the third anomaly discovered by scientists.
We all know that planets and asteroids in the solar system orbit in a flat disk-like region, which is the protoplanetary disk. A protoplanetary disk is a huge cloud of gas and dust formed by the rotation and collapse of the protosolar nebula during the formation of the solar system. In the protoplanetary disk, material gradually condensed into celestial bodies of various sizes, eventually forming the solar system we see today.
So, what is the Oort Cloud? And how did it come about?
The Oort Cloud is a theoretical globular cloud consisting mainly of icy planetatoplanets that are believed to orbit the Sun at a distance of about 100,000 astronomical units (2 light-years). This distance is very far, thousands of times farther than the farthest planet, Neptune, and even half the distance between the Sun and the nearest star, Proxima Centauri.
There is no direct observational evidence for the existence of the Oort Cloud, but scientists have deduced its existence based on studies of comets. Comets are small bodies of ice, dust, and rocks that, as they approach the Sun, are subjected to solar radiation and wind to form a bright tail. Comets can be divided into two categories: short-period comets and long-period comets. Short-period comets have periods of less than 200 years, and they come mainly from the Kuiper Belt and discrete disks, both of which are located outside of Neptune's orbit. Long-period comets have periods greater than 200 years, even millions of years, and they mainly come from the Oort Cloud.
Scientists believe that the planetesinos in the Oort Cloud were all originally formed close to the sun, but early in the solar system, due to the gravitational pull of giant planets such as Jupiter and Saturn, they were thrown out of the protoplanetary disk and into highly elliptical or parabolic orbits. These orbits make them very far from the Sun at aphelion and very close to the Sun at perihelion. At aphelion , they are affected by the gravity of nearby stars and the Milky Way, causing them to gradually form a spherical distribution. At perihelion , they are perturbed by the gravitational pull of planets in the inner Solar System , making it possible for them to enter the inner Solar System and become observed comets.
There may be trillions (1012) of planetesines in the Oort Cloud, with a total mass about five times the mass of Earth. They are tens of millions of kilometers apart, so collisions are rare. They are mainly composed of solid volatiles such as water ice, ammonia, methane, etc., so they are also called "dirty snowballs". Some planetesinatures may also contain rock or metal components, similar to asteroids.
The Oort Cloud is the outermost layer of the structure of the Solar System and the edge of the Sun's gravitational sphere of influence. It is a relic of the formation of the solar system and the cradle of comets. Its existence reveals to us the origin and evolution of the solar system, and also shows us the mystery and beauty of the universe.
epilogue
Through the above introduction, we can see that there are many surprising and magical phenomena and structures in the solar system. They not only give us a deeper understanding of the solar system, but also give us more imagination of extraterrestrial life.
Water on Earth, the location and distribution of planets, and the Oort cloud, these are three "anomalies" in the solar system and three important conditions for the existence and development of life on Earth. Without these "anomalies," there would be no life-friendly factors such as water, temperature, sunlight, and comets on Earth, and there would be no us.
So, how do these "anomalies" come about? Are they natural accidents, or are they intentional designs? Are there aliens hidden behind them? Are aliens really manipulating the Earth and the solar system?
These questions may never be answered, or they may one day be revealed. But in any case, we should be thankful for these "anomalies" because they give us life, wisdom, and exploration.
