question 2: why is the technology of aliens so much more advanced than that of the earth? It has been proved that there are no aliens in the solar system.
In the vast expanse of space, there are countless stars, among which the closest star to the sun is called proxima centauri, which is located in Alpha Centauri (scientific name: Alpha Centauri C), only 4.22 light years away from the sun, equivalent to 39,923.3 billion kilometers. If you travel to proxima centauri by the fastest spaceship, it will take you 17, years to go back and forth. It is conceivable that the universe is vast, even though it is near by.
At the present level of science and technology, it is impossible for us to reach proxima centauri. If there are aliens in neighboring galaxies who can reach the earth, from this point of view, the level of science and technology of the aliens is many times greater than that of human beings. Man has only been to the moon at present, and Mars is only in the plan.
However, at present, aliens only exist in science fiction works. Not to mention the discovery of aliens, only a few hundred planets outside the solar system have been discovered so far. There's no sign of aliens at all.
question 3: how advanced can the technology of aliens be? First of all, aliens are not sure. How can we know how advanced they are? Even if there are aliens, it's a top secret file.
Question 4: Why are people on earth at the bottom of genes? How many aliens are better than us in science and technology? Aliens will jump into wormholes in an instant by UFOs, and then start to calculate with calculators (ignoring the arrival of time and distance). As for how much better than us, scientists still don't know. I hope to adopt it! ! ~ ~ ~ Einstein's potential is only 7%. If human potential is fully realized, what other superpowers might be gained? Hawking thinks that aliens are more advanced than us. < P > Should human beings let alien civilizations discover the existence of the earth? Scientists have different views on this issue. Some scientists believe that if hostile aliens know about our existence, we will face the threat of alien invasion, leading to the destruction of the earth. In their view, if aliens master the technology that can travel through space and fly to the earth, their military technology will far exceed that of human beings, and any resistance of human beings will be ineffective.
Hawking, a famous physicist, warned that aliens may come to the earth to plunder resources. He pointed out that human beings should take all possible measures to avoid contact with aliens. Hawking said: "aliens may be far more advanced than humans, so that we don't want to contact them." If aliens come to the earth, the result will be like Columbus landing in America, and we will suffer bad luck like the Native Americans at that time. "
question 5: alien technology is really not much more advanced than the earth. there is no empirical evidence so far, and we really don't know. Maybe some are more advanced than the earth, and some are behind it.
Question 6: How high is the technology of aliens? I think so: If aliens can come to the earth from several light years away, it means that their technology level has far surpassed that of us. Because it took us more than 3 years for the space probe launched by human beings to fly to the edge of the solar system. But there is no conclusive evidence to prove that aliens have visited the earth!
Question 7: Why are aliens more technologically advanced than earthlings in most sci-fi works? There are two categories of sci-fi novels: one is martial arts novels, mainly fighting+love+justice, and the background uses sci-fi future. This category mainly aims at satisfying the readers' obscenity. Very little rationality. The other is the science fiction novel, which mainly evolves the hypothetical facts of the unknown future of human beings, and this part is not necessarily related to the presence or absence of aliens.
So, you are watching a sci-fi martial arts erotic drama, and the alien is just a clown, so don't think too much about rationality.
question 8: does the advanced science and technology in the United States come from aliens? it is not reliable to believe this. American science and technology were not advanced from the beginning. After entering the 2th century, the United States has become the richest country in the world, but it still lags far behind Britain, France and Germany in science and technology. At this time, there were two world wars, and a large number of scientists had to go to the United States to make a living, especially before World War II. Since 1933, Hitler has persecuted Jews and political enemies at home. So a large number of professors and engineers from various universities fled to the United States (for example, Einstein, a professor at the University of Berlin), and nearly 1, people were qualified as "senior talents". At that time, the total number of professors from various universities in the United States was so much, not to mention that compared with Europe, the quality of local scientists in the United States was generally poor. In addition, there are some scientific and technological personnel who fled from civil strife in Russia (such as Sikorsky), and Enrico Fermi who fled from fascist Italy to the United States.
After World War II, Germany's position as the world's science capital plummeted, and the United States became the world's science and technology center.
The scientific and technological research in modern America depends on the doctoral graduates trained by various universities in the United States. China's Tsinghua University, Peking University, China University of Science and Technology, and India's Indian Institute of Technology provide a large number of talents for American science and technology every year.
