Is the solar system really a "laboratory" for aliens? Not long ago, NASA scientists in the United States claimed that "there is an unknown abnormal gravitational wall at the edge of the solar system", which once again triggered speculation that the solar system may be a "laboratory" or "zoo" of extraterrestrial advanced civilizations.
In fact, Tesla, a tech wizard, had a prediction a hundred years ago: there is a huge protective shield in the outer periphery of the solar system, which is an insurmountable obstacle for human beings.
These two are so similar that they have to be thought about and taken seriously.
First, let's look at the peculiarities of the solar system. In the universe, Earth is the only planet known to have life, at least as we know it. The existence of life requires many specific conditions, such as water, suitable temperature, chemical elements, etc., which are not common in the universe. Thus, the solar system became a shining pearl in the universe that may have attracted the attention of aliens.
In addition, many phenomena within the solar system are also puzzling. For example, the existence of the Moon plays an important role in the evolution and stability of life on Earth, but its origin remains a mystery to this day. Some scientists believe that the Moon may have been a "device" placed by aliens to observe the Earth. This view, while quite controversial, is also a logical hypothesis.
Perhaps, the extraterrestrial advanced civilization is doing some experiments and needs to observe the changes in human society on a regular basis, so there are often some UFOs on the earth, which can be explained. Extraterrestrial super civilizations have built this "protective shield" for the solar system, which not only prevents life in the solar system from being interfered with and threatened by external interference, but also prevents humans in the solar system from "escaping" from the solar system.
In the infinite universe, the solar system is like a tiny speck of dust, but it is unique in our hearts because it is our home. Therefore, it is not surprising that any anomalous changes in the solar system, or just a little speculation, will cause great curiosity and even uneasiness.
