Progress of science and search for eternity
Until fifty years ago, no one knew enough of the state of the cosmos to speak of the existence of Earth-like planets. If it was written about it, it was only in science-fiction novels, and in a way very far from reality. Tales of green men reigned, aliens with weird looks and aliens threatening our civilization. Most people took these stories as a fantasy that was unscientific.
Since the second half of the twentieth century, thanks to new telescopes placed in space, there has been a breakthrough in knowledge about the structure of the universe. This was mainly due to the astrophysics. The significant development of quantum physics also made a significant contribution to the understanding of energy changes in the cosmos. The world of science has suddenly received sufficient tools to make us realize that the universe once arose and that it is an unimaginable space made up of billions of galaxies accompanied by dark matter and dark energy. Larger and larger new generation telescopes and space probes have enabled scientists to explore the universe deeper. In the late twentieth century, the Kepler telescope was sent into space, which caused a rapid influx of data on the state of outer space. The global arms race, which also began to embrace space, had an impact on the progress of knowledge. There began a flood of discoveries of millions, even billions of planets, called exoplanets, or Earth-like. Along with these discoveries, there were many speculations about the possibilities of living in space.
As a result of these discoveries and intensive analysis of their results, scientists realized that we are almost invisible pollen in space, even on the scale of the galaxy known as the Milky Way. It was especially it who became the object of large-scale observation and research. It resulted in understanding many things that we had not known before. Today we know that the Milky Way itself may have eleven billion exoplanets associated with two hundred billion stars. Taking into account the so-called red dwarfs, i.e. stars much lower in brightness than the ordinary star, the number of planets that can be classified as exoplanets has increased to thirty-three billion, a number that exceeds any previous image of space. Even if these data are approximate, their enormity is shocking. The "reserves" of space appear to be inorganic. This fact makes many people reflect on the importance of the existence of the structure of the cosmos.
The problem of the existence of other extraterrestrial civilizations has become the subject of essenceism in the search for the possibility of repairing our civilization. Currently, some scientists are of the opinion that if somewhere in the universe there would be a civilization of intelligent beings, then probably people similar to us should live there. The course of evolution based on the laws of physics, chemistry and biology, the widespread operation of which has been noticed as a result of studies of gases and minerals found in the universe, would make those civilizations similar to ours. For example, fish living in the waters of other planets would be the same as ours. The same is true of all nature, including humans.
As a result of these discoveries, there is a desire to get into a rocket carrying a suitable spacecraft and investigate whether there is a civilization similar to ours somewhere in the cosmos. It is the closest object in our galaxy that promises some hopes for finding life is a group of stars and planets called Kepler 62. However, I would like to inform you that a trip there by the most modern spacecraft would take 200,000 years, which is much longer than the known duration of the mainstream of our civilization. Let's forget about this type of travel and be content with the information that reaches us at the speed of light.
For now, it is worth noting that the probability of intelligent life somewhere in the universe is quite real and that there may be many such places. The calculus of probability shows that only in our galaxy can there be planets on which intelligent beings could live. That is why science so intensively studies the cosmos, using the best equipment and the knowledge of the most talented astronomers. If we add to this the study of the state of energy and matter in hadron colliders, we can hope that soon we will better understand the processes that influenced the formation of the cosmos. It is about knowing the moment of its creation, up to the moment of the appearance of an intelligent being, which is a man. I would like to add that the above analysis of the state of the cosmos is aimed at finding out the answer to the question of whether the universe was created by itself or whether it has its creator. Therefore, I hope that the world will soon circulate the information that not only are we not alone in the universe, but also that we have discovered the secret of its creation.
