Interesting theory that maybe we are alone in our galaxy

When we are talking about the theory that maybe we are alone in our galaxy, we must say that maybe we are lucky. Because if there would be other technical civilizations around us,  our faith would be destroyed by the attack of aliens. Here I must say, that if I’m honest, I would win everybody in argumentation when we are talking about SETI-program and alien civilizations. I must choose only the distance, what is so huge, that the radio-impulses from the Earth would not reach that point in our lifetime.


So I can say that maybe there is technical civilization in the distance of thousand light years. And that means the signal from Earth and that point would travel thousand years in one way. If the alien would answer immediately, the signal would travel 2000 years before we would get the answer. This means that none of us would live so long, that the signal would influence our life. That is the problem with searching the extraterrestrial intelligence. Our communication is connected with the speed of light, and that means that the message to Alpha Centauri would travel four years in one direction.


And if we would send the probe to that solar system, would the message alone travel eight years. Of course, the trip to that system would take very long time, and the spacecraft would need extreme independent artificial intelligence to accomplish the mission, what should take thousands of years. And this is Alpha Centauri mission, not any trip to some system like Gliese-581, what is 20 light years from Earth. In here I will write the hypothetical civilization what locates in this solar system.  And then the message would travel 20 years to that solar system, and then aliens must first realize, that there would be the message in their radio telescopes and other systems.


Then they must break the message, and what do you think, do they give the answer? If human race would get the message from outer space, I think that I would take tens of years before we could break the code of that message. And then it would take a long time before we would answer to that message, and first, we must collect the information about those hypothetical aliens. We must know if they are hostile or friendly, and it would take a long time. And we have not contacted with aliens, who live in Gliese system. Or maybe NSA hides that material. Who knows the truth. But we are living in the lonely solar system outside the main milky way formation.


That would save us from the interplanetary conflict. When we are talking about SETI-program, we might get contact to another civilization in tomorrow or maybe it would take 1000 years. And the problem is that we don’t even know, where we must look for that alien.


Maybe in someday, we can create an electromagnetic black hole for communicating with probes, what are send in the orbital of other stars. That wormhole would be smaller than the atom, but using this technology in communication, we must know where to send the signal. The probe is little bit different thing than other civilization because we would know where that thing is, and if we will talk about other civilizations, we would not know where they are.


And there are many stars even in our Galaxy. So if we would want to send the targeted message to all of them, would that take very long time, and in this case, we might say only “Hi we are Human race and living on Earth”. This message would not be very long, but there are 250 billion stars in our Galaxy. And sending the message to all of them would take time. There are 31 556 926 (Google straight answer) seconds in one year. So sending the message to 250 billion stars would take extremely long time. And we would not know any other intelligent civilizations than the human race.

NASA:s Kepler-telescope is near end of the fuel, and it can be pointed to some specific solar system for collecting specific data from the specific exoplanet system

NASA:s Kepler mission is coming near its end, because fuel of the telescope is running low, and this means, that this telescope cannot be turned to the targets anymore. Kepler has been found new exoplanets, and it has given information, that maybe there is a habitable planet somewhere in the Universe.


Some people think, that maybe this telescope can be pointed at some point in the universe, where are known exoplanets. This system could be Gliese-581, or some other system, what can be observed from Earth, and this telescope can collect the information of this particular system. Maybe it should be Alpha Centauri, where we're at least founded exoplanets.

But this is only speculation. Kepler telescope has been used to demonstrate low-cost space telescope technology, and it has given very much for science and engineering, and the data what this telescope have been collected, would be analyzed years after its mission have been ended. And this information would be used to selecting targets for James Webb and other very powerful telescopes, what operates outside Pluto trajectory.


James Webb-telescope would represent the brand new design for space telescopes. This telescope has the table, where the telescope optical system stands. This structure allows turn telescope the way, that the guidance rockets would not need use every time when this telescope selects the target. And if those telescopes would send far enough from Earth, the temperature would be very low, what allows use also infrared radiation for making observations for other solar systems.
