Why alien civilizations do not come to Earth

Why is Stephen Hawking already trying to stop China's Eye in the Sky system from sending out messages of exploration to the universe?

What are the unknown secrets of the mysterious universe?

Do aliens exist in the endless universe, as rumored on the Internet?

Stephen Hawking has repeatedly warned humans not to try to contact extraterrestrial civilizations and has been urging China not to send information to the universe when the Chinese Eye in the Sky was first built, lest it be discovered and destroyed by a terrifying alien civilization.

But a famous Harvard professor in the United States has made a statement that the birth of the solar system in the infinite universe would have been billions of years later than other galaxies, and if there were advanced civilizations in other galaxies, then our Earth would have been discovered long ago, and today we have not received any reply from alien civilizations.

Perhaps hundreds of millions of years ago when there was no sign of life on Earth, an alien civilization had already discovered us. In the vast universe, Earth, as one of the eight planets in our solar system, has developed science, civilization, and life-form structure to date, but none of this is a special existence in the universe.

In the mysterious and unknown universe, there are many unknown things that we humans have not been able to explore, Hawking as a famous British physicist and cosmologist, in the field of astronomy and geography for the world to bring a very shocking impact.

As a famous British physicist and cosmologist, Hawking has made a great impact on the world in the field of astronomy and geography. During his lifetime, he was extremely passionate about exploring extraterrestrial life and believed that the unknown mysterious alien civilization would most likely put the Earth in danger, and the boundless universe has made human beings feel very curious.

Voyager 1

To know whether there are creatures like us in this vast universe, Voyager 1 was launched in 1977 to explore the unknown creatures in the universe. Humans want to get in touch with extraterrestrial civilizations by transmitting radio, but even though the speed of radio has reached the speed of light propagation rate, in the infinite universe still seems to be very slow, and the infinite increase in the propagation distance, the radio signal will also be damaged and weakened.

The scientists' analysis speculates that even if other information has the existence of extraterrestrial civilizations, that can receive the signals we transmit tens of thousands of light years later, their technological development must not be a level with the Earth. In short, as the distance increases, the signal becomes weaker and weaker. Aliens who can receive weak signals tens of thousands of light years later must be technologically advanced.

According to the conclusions reached by astronomers in the last hundred years of exploration of the universe, no signs of life have been found on other planets in the solar system so far, and only humans on Earth are the only intelligent life forms that exist in the solar system. If extraterrestrial civilizations exist in the vast universe, they must be from planets outside the solar system.

Today, humans have not been able to master the technology to cross the solar system, but those far higher than the Earth's civilization of extraterrestrial beings can easily enter the solar system, which will be an unprecedented catastrophe for the Earth.

Is the rumor that humans have been living under the surveillance of aliens true or false?

Why don't humans go to the universe to explore unknown secrets? What are the difficulties behind this issue?

Is mankind as insignificant as a mole in the face of alien civilizations?

Some astronomy experts say that the 29 alien civilizations observed in the universe are well placed to easily observe the vital signs of the Earth and detect the wireless signals sent from the Earth. If there is life in these 29 extraterrestrial civilizations and a high level of civilization, then it is very likely that these 29 extraterrestrial civilizations have been observing humans for thousands of years.

As the saying goes, there is a world beyond man, and there is a more infinite world beyond the vast universe that we know continuously. Human detection of unknown creatures, issued Voyager I, has been flying in the universe for 44 years, the distance flown is as high as 22.8 billion kilometers, is the farthest human probe issued from Earth, but even so, it still failed to fly out of the solar system.

According to astronomical experts guess, Voyager 1 will take about 300 years to reach the edge of the solar system children, who want to cross the edge of the solar system will take at least 30,000 years.

Although the probe can fly in outer space for a long time, in contrast, the very short life span of humans is unable to complete hundreds of years of flight.

Such a long flight time is an obstacle that no human can cross. Since humans can not leave the Earth, it is also difficult for alien civilizations to leave their planet to go to distant alien planets. Nevertheless, there are still many people who are still worried that their every move is under the surveillance of aliens. In the vast universe, the galaxy has been in existence for 13.6 billion years, and our planet has existed for 4.5 billion years, but the life span of humans is only a few hundred years, compared with the life span of these planets in the billions, how insignificant humans seem.

Stephen Hawking has always believed that extraterrestrial civilizations are very powerful, and in 1964 Soviet astronomers proposed an extraterrestrial civilization level, divided into three levels of alien civilizations, the higher the level, means more power, but the human civilization level is only 0.7, a civilization can not reach the Earth is very backward.

Stephen Hawking also believes that alien civilizations are more advanced than human civilization, and astronomical experts have long given the statement that the infinite universe is like a dark vortex, in which there are too many unknown civilizations, living here must be treated with care, if once discovered by a more advanced civilization, then will certainly suffer an unprecedented blow.

Therefore, while satisfying their curiosity, humans should also pay attention to the sense of prevention. Nowadays we think we have a higher civilization and confidently send detection signals to the universe, alien civilizations see us as ants, and simply do not want to pay attention, just like the ants living on Earth.

Maybe they also have their civilization and have sent signals to humans that they think are advanced, but we not only do not understand but also do not care, it is just an ant that does not exist in our eyes. Perhaps the current human race is also just non-existent in the eyes of the alien civilization.
