If the earth is not a special existence in the universe, then human civilization will not appear lonely. Moreover, Milky Way is also relatively lively in scientists' predictions, and the Decree formula seems to be able to prove that the earth is just a drop in the ocean in the universe.
So what exactly does this formula reveal? Can it prove that Earth civilization is perhaps not the only way to nurture life?
Astronomical Exploration
's exploration of life, humans have been puzzled by this since civilization, and it has been recorded in the ancient Greek civilization more than 3,000 years ago.
The ancients' exploration of astronomy has never stopped. Although the history of human beings' aerospace history has only been a hundred years, this seems insignificant on the scale of the universe history.
But this century of time can help us further explore the development of cosmic civilization.
So after we had a large amount of detection data, we further had more doubts. For example, will the earth be just a special existence in the universe?
. Does humans live on the earth have a single form of life? If not, how far is the alien civilization from us? Can their way of existence be discovered by humans in modern times?
If the earth is a special existence in the universe, will our special status disappear one day as the universe expands, or will it continue to be like this? So, how likely is the planet like Earth exist in the universe?
As humans further explore astronomy further strengthened, we slowly discovered a truth: the earth seems insignificant in the solar system, but the solar system seems too small in the Milky Way.
and all this is endless, because there are galaxy clusters above the Milky Way, and then there is Virgo galaxy clusters on it.
and so on, we don't seem to detect the maximum astronomical level.
Moreover, the number of stars in the universe exceeds human imagination, and the detectors launched by humans have not yet walked out of the solar system, let alone entered interstellar space .
But during the long-term space exploration process of humans, we have 12 astronauts landed on the moon one after another.
Therefore, we have more confidence in the exploration of each planet. Perhaps one day in the future, human beings will be able to enter interstellar space earlier.
, but this journey has left us with a lot of work. Another problem facing mankind is whether there are still miracles like life on other planets?
Life Forms
Scientists have made countless bold guesses about this issue.
and even famous international physicists like Hawking Einstein, they all nodded frequently to this, believes that the earth cannot be the only and special existence in the universe. Planets like Earth, or forms like life, will not exist alone.
However, looking within the solar system, humans have not been able to detect mutual friends in the same home through technology. So we can only hope outside the solar system, but the cosmic space that humans can detect at present is only based on the earth as the core point.
: How prosperous is the depths of the universe, and where is the margin? Will it enter a compressed state after expansion? All these issues still need to be left for time.
But what is surprising is that humans have developed a large number of radio telescopes. We can use these tools to receive various information from the depths of the universe. Although humans have not received any signals about aliens until now, more astronomers are not sure that Earth civilization is the loneliest existence in the universe.
Because more people still believe that human beings will not be the only intelligent civilization in the universe. Even among various cosmic civilizations, we may still have a lot of room for evolution, but under this assumption, many scientists have provided theoretical support.
960, scientists from the United States Frank Drake proposed the famous Drake formula based on this hypothesis. In short, he believes that the number of civilizations that may communicate with us in the Milky Way is the result of multiplication of the number of stars in the Milky Way, the ratio of stars to planets, the number of -type geography in each planet system , the proportion of life evolution habitable planets, the probability of high-quality organisms, the probability that high-quality life can communicate, and the proportion of scientific and technological civilization in the life cycle of planet .
Drake formula
Seen this way, the Drake formula seems to make some sense. It covers all the possibilities that can also nurture civilization or life in other forms besides the earth. However, the factors involved in this formula are too huge, so it also contains a lot of estimation value.
For example, if we only use today's technological level, we still cannot detect the number of stars in the Milky Way.
scientists are currently predicting through estimates that the number of stars in the Milky Way is about 400 billion. As for how many of them are, scientists can only shake their heads and cannot give an objective and specific value.
Therefore, many problems are only available for humans to estimate.
But a pity, mathematical formulas can only be multiplied by various numerical values to obtain a specific range. In this way, humans can only maintain assumptions and conjectures in various detections of astronomy. An attitude like
may help us detect more useful astronomical information, but at present, the scientific and technological level we have is still very heavy to leave to humans.
For example, what are the numbers of stars and planets in the Milky Way? Can we make a preliminary estimate of the Drake formula based on the approximate interval range?
Once many scientists conducted a large number of explorations through this formula, and finally concluded that humans are not the only and special civilization in the universe, and cosmic civilizations like us are actually not uncommon. Even humans can prove that the earth's civilization may be even more ordinary than we imagined through this formula.
In other words, in the depths of the universe, smart civilizations that are more advanced than the earth's civilization are not only very common, but only human research has found that the number is at least 20.
In this way, life on earth may really not be the only one in the universe. Perhaps humans do not seem particularly lonely in the universe. But as far as Drake's formula is concerned, its estimation effect is more significant.
Perhaps only in the future, our technological level will become more and more developed, and we can further verify the various hypotheses about the universe with data. Perhaps that day we can uncover more mysteries.
