Two more decades will meet

500 billion planets in the Milky Way and also many planets in one hundred million other galaxies. In that huge number, it's hard to say that human beings are the only intellectual beings in the universe.

The hypothesis is that humans are standing at the threshold of encounters with intellectual brethren increasingly supported by many astronomers. The amazing results of the ' Kepler ' telescope that are flying in orbit to search for strange planets have shown that modern science can do everything. Next year scientists will launch a satellite into a four-year research program, surveying over 100,000 planetary systems.

If ' Kepler ' could detect planets similar to Earth, the group participating in life search projects on ' strange ' planets (SETI) could steer their radio telescopes around. more distant space is aimed at signals that characterize a developed civilization. Now radio astronomers are forced to listen to the universe near and without specific research goals.

The famous American astronomer Frank Drake, head of SETI, said: ' All inventions in recent years bring us optimism. We absolutely believe that the knowledge gained in the past 20 years allows the discovery of life outside of Earth. It is not excluded, that is the life of intellectual beings '.

Many scientists share Drake's optimism. But many people think more pragmatically, assuming that any organic life is completely unlike life on Earth. Biochemists studying the biosphere rushed to cool hot heads - life on other planets could be made up not on the carbon base as on our planet, but on the basis of other chemical elements. It is possible that alien life has to adapt to survive in conditions that stifle Earth.

' Kepler ' first task is to search for Earth-like planets not only in size but also on surface temperature and many other factors. Perhaps people of those worlds can live at high temperatures like craters, for example?

With an unequivocal view of the existence of life, we will not meet the species of galaxies, just because we don't realize that ' they ' have something similar to our intellect. . Without such false prejudices, how can we be in contact with ' them ', based on a single frame of reference?

But even in the minds of optimists, the answer is still full of skepticism. They argue that if life can exist in very diverse conditions, it means that it is more widespread in the galaxy than we often think. In that case, it is difficult to define the goal clearly but at the same time the chance of identifying it randomly also greatly increases

In order to create a direct contact, those who believe the meeting with aliens can happen soon, say, necessarily find a way to solve the problem. The solution is not right now but when we can afford to study neighbors in the universe.

Hundred years ago, fiction writers described the reunion with aliens. Russia's famous fiction writer Victor Selina commented:

- Fiction writers often tell them to always stand at the forefront of scientific progress and forecast future events. But if there is a coincidence of their forecast with actual science, it can only last a few years or so several decades.

- However, to answer the question of ' when ' (but not ' if ' anymore), there will be a meeting between humans and intellectual beings (not necessarily ' alien '). then competent people are not fictional writers or filmmakers. It is the scientists of the various forms of life that will stand out to introduce us to incredible creatures that are so incredible that the body and logic of ' they ' are completely unlike us. at all.

Even so, the hope that humans are not alone in the universe has never been lost. People are waiting to persevere in a meeting that promises many amazing things.
