There are many problems to search for extraterrestrial life forms.

If extraterrestrial lifeform is primitive like algae or bacteria researchers must search for the products of those organisms' metabolism. And the biggest problem is that exoplanets that can host life are very far away.

Researchers have no information on what kind of creatures they should search for. Or what those primitive aliens are eating. Without any bacteria, samples are very hard to make any kind of model that those researchers must search for. 

And for those models, the researchers must use terrestrial bacteria as the model. So when we are thinking of those hypothetical bacteria as organisms that lived billions of years on some planet those organisms would be fully adapted to their home planet. 

In some scenarios in the deep oceans of some exoplanets live organisms with the capacity to make oxygen by using electric cells and electrolysis. But even if those extraterrestrial fishes seem like fish they don't have any other connections with fishes on Earth. Except both of those organisms are living in the water. 

There is a possibility that some extraterrestrial aliens have green or red skin. That makes their skin photosynthetic. The green skin means the alien species would have chlorophyll in its skin cells. And red skin means that the alien has the same molecule. That makes purple photosynthetic bacteria photosynthetic. 


******************************************************************

There is the possibility that we already have alien transmissions. But we cannot separate the data from cosmic background noise. 

That is one of the most interesting scenarios of the SETI program. Things like BLC-1 and Wow! signals are interesting. And the problem is that they happened only once. 

But the fact is that use of hydrogen's alpha line frequency is ineffective for data communication. In that frequency, the cosmic background noise disturbs information. And at least high-speed encoded data transmission is very difficult by using the hydrogen line's frequency. 

***********************************************************

But when we are searching for an intelligent alien civilization. We must understand that the search for those aliens is a very difficult mission. Even if aliens use radio transmissions for communication by using synthetic radio frequencies searching for those aliens is extremely difficult. 

And the reason for that is that radio astronomers have no permission to listen to those frequencies. Listening to synthetic radio frequencies is prohibited because of data security. This thing is one of the biggest problems in the SETI program. The synthetic radio frequencies are allowing better change for everyday data transmission than hydrogen's alpha emission line. 

But for some reason, we just expect that hypothetical aliens are keeping contact with each other by using hydrogen lines in communication. That thing causes very bad disturbance for those radio transmissions. Of course, aliens must use the numeric system that we know that we can even separate the alien transmission from the background noise. 

There is the possibility that we have alien messages but we cannot recognize them. So we cannot separate that purpose information from background noise. And the reason for that is we have no key to alien data transmission. But there is no confirmation for that allegation. And that is only a hypothesis.

Where are aliens hiding?

   

 Where are aliens hiding?



Above: fictional space cruiser from "Star Wars" movie

Are there other technical advanced civilizations near us?


Are there other technical advanced civilizations near us? That is one of the biggest questions we ever faced. There are no official contacts with aliens and the rest are purely hypothetical thoughts and models. 

But there is the possibility that SETI (Search for Extraterrestrial Intelligence) will make contact tomorrow. Or maybe it takes thousands of years for taking confirmed signals from the other civilizations. 

Tools like the James Webb telescope and quantum computers are the most powerful tools ever been used for that kind of mission. The James Webb telescope can find the Earth-size planets orbiting other stars. But the main role in the SETI program plays radio telescopes. The requirement for making contact is that also aliens are using similar technology with us. 

We don't even know if the aliens have radio telescopes? And what frequencies they are listening to. Getting that information requires contact with aliens. And without that information is very hard to make contact. There are no confirmed alien signals so everything we write and talk about intelligent alien civilizations is purely hypothetical and theoretical discussions. 


What if advanced civilizations use unmanned automatic operating probes. Which are controlled by very advanced AI for interstellar missions? 


The answer is that nobody knows. Officially there is no evidence of intelligent alien civilizations. But there are many forms of how those civilizations can exist near us. One of the possibilities is that there could be probes that other civilizations sent. But this is only a theory or theoretical model of how to travel to stars. At first, there would send robots to find out suitable locations. 

The thing is that if aliens use robots that are controlled by artificial intelligence, they must not worry about flight times and other kinds of problems. The journey between stars could take even millenniums. 

And those probes would send data to their senders. That thing requires technology that makes craft able to fix itself. The problem is that the sender can forget those probes if there is some kind of internal problem like the war on their planet. 


Why the Wow!-signal(captured, August 15, 1977) and BLC-1 (captured, December 18, 2019) signals are unique?

The origin of BLC-1 (Breakthrough Listen Candidate 1) Remains a mystery. Things like broken computers are seeming good, but the problem is why those things that are causing that kind of things are not happening before. 

Same way, why have some high-energetic particle impacts with radio waves from Proxima Centauri haven't cause that kind of signal before? Or if the source of those signals is alien transmitting, why do those transmissions not repeat? The same thing that thing supports both theories. Why do those signals BLC-1 and Wow! are unique? 

Both natural and alien source theories can explain that thing. But there is some extraordinary in the structures of comets. That is mentioned as the source of the Wow!-signal from 1977. If the comets are the source of that signal there is the possibility that there was some kind of unique layer in those comets. 


Technical advances aren't forming without intelligence and motivation. 


The creature can be very intelligent. But that thing doesn't mean that it makes technical equipment. For creating new technical equipment. Intelligence requires motivation, tools, and knowledge on how to make something.

If that intelligence doesn't have the needed information the intelligence can ask that thing from something. or it can start to search answers for testing ad study the suitable solutions for making a new car or interstellar spacecraft. 


Three major things are dominating the R&D (research and development processes. 


1) Level of intelligence


2) Information that intelligence uses for the project. This part includes skills and systems what the project requires. 


3) And motivation. There must be time and other resources for completing the project. 

The thing is that intelligence is not the same thing with technical advances. Intelligence makes technical advances possible. But research and development (R&D) don't happen without motivation. 

The thing is that the lack of information means that there is a lack of stimulus. And creature requires stimulus for creating new solutions. Outcoming information creates motivation for creating new technology. 

If there is no motivation or will to get knowledge about something. When we think of that intelligence and advances are the same things. 

We are wrong about that thing. Intelligence makes it possible to create technical advances. But that requires motivation and will to get knowledge of how to make technical solutions. In the case that we want to make contact with civilization by using radio telescopes. That civilization must also have radio telescopes. 

When we write about possibilities to communicate with other civilizations we should rather say. "Communicate with other technical advanced civilizations". That communication requires that the civilization has similar communication equipment with us. And the thing is that even if that hypothetical civilization has the radio communication equipment. 

That thing doesn't mean the hypothetical civilization uses similar radio telescopes that we use. The thing is that without contact we cannot know how to communicate with aliens. And without that knowledge, we cannot make contact. There are a couple of promising signals and the only problem is that they are not repeating. The same thing that makes them promising makes them also uncertain. 

If the source of those signals would be a star these signals like Wow! and the 2019 signal from Proxima Centauri known as BLC-1 (Breakthrough Listen Candidate 1)would be a star they should be repeating. But because those signals were unique. That thing also supports the origin of those signals in chemical or electrochemical reactions. But it's also evidence against "natural source". The question is why that reaction happens only once?

The source of BLC-1 has been explained as the plasma impact or some other type of high-energetic particle impact that could disturb radio signals. But again the question is why that signal ever happened again? And why have similar things are not seen before? There is given also an exploration that a broken computer can give that signal. But the question is why that kind of effect has not been seen before?

The solar system itself is inhabited. But the thing is that there is the possibility that some kind of probe could send that signal. But is the position of the probe at Proxima Centauri. Or is it manmade and closer than we think? The fact is that nobody knows what caused that signal that was received in Parkes observatory on 18 December 2019. 

If the source of the Wow!-signal was in comets why did those comets send those signals only once? Was there some unique layer of material that sent that 72 seconds radio transmission to the Big Ear telescope in Ohio sate university? 

That thing means that their source could be some kind of reaction in AREA-51 or some other research plant. And they were formed. When some exotic materials are stressed. By using electromagnetic radiation. If aliens send those signals why they don't repeat them? So the source of those signals is unknown. 

Maybe in the case of the Wow! signal it was some kind of comet, but why do other comets not make similar effects. And why do those comets send that kind of signal only once? That is the thing why the source of those strange signals is unknown.

Could the iron ore use as the antenna for radio telescopes?


Could the iron ore use as the antenna for radio telescopes?

Is it possible to transform the Rocky Mountains and Appalachian mountains iron ore the natural antennas for radio telescopes?


Could iron ore act as the natural antenna for radio-telescopes, and the answer is that in the iron ore is the same iron with the radio antennas. So if we would benefit natural deposits of iron ore, we must just check, that the radio waves are touching the ore, and then we must connect the amplifier system to the iron ore.

There is one little but a very interesting coincidence with the form of Big Ear(1) telescope and the terrain form of the United States of America. The mountain areas of the USA are like the antennas of the "Big Ear" telescope.

And sometimes has been introduced ideas, that the iron ore of the Rocky Mountains and Appalachian mountains can be used as the natural antenna for radio telescopes, which means that there is possible to create "Bigger Ear" telescope. That means that the amplifier of the radio telescopes can be connected to the iron ore, which will transform mountains into the bigger version of the "Big Ear" telescope.

The "Wow!" signal( 2), and why the magnetic fields, what radio signal passes are making it very difficult to determine the origin of that signal?


The main reason, why the "Wow!" signal is really hard to analyze is that the signal is unique. That means that only the "Big Ear" has noticed that thing. This famous signal has been caused thoughts that what if the system would be out of the electricity just at that time? And another thing, what makes this case lucky is that "Big Ear" is the fixed system. The telescope is two fixed antennas, and that allowed to catch the signal. If the telescope would be aimed, and the aiming point of the telescope would be different, there would be no "Wow!" signal.

And there is claiming that somebody has asked did humanoids or whatever those creatures are known about the error in program code?  Maybe that thing was a joke, but it's quite a creepy version of humor. 


This "joke" is quite bad, but if the humanoids would know the error, that the computer couldn't determine the antenna what will catch the signals, and they would predict that there is an update brings, they could expect that the telescope was out of use. And then they would send that message.

The calculation of the point, where the famous signal came should not be very difficult. The reason for missing coordinates is that the computer programmer, who has made the program, what is used to isolate the signal didn't determine, which antenna caught that signal. So the thing that must be done is just calculate the point, where the message is coming for both antenna, and then the optical telescopes can turn to those points, and observe is there some kind of star, where that signal can come from.

And in this case, we must realize, that the location and direction of the signal could be impossible to determine, even we could determine the point, where the signal is coming. The black holes can turn the direction of the radio waves, and that would make possible, that the signal would come originally from a different direction, what the "Big Ear" would detect. Another problem is the "Radio maser emission", what means that when the radio signal faces another radio source what will transfer energy to it, would that make the effect, what is called as "virtual transistor".

So that means that the outcoming radiowaves are acting like radio amplifier. This makes impossible to determine the original transmitting energy. We can see the same effect if the signal travels through the magnetic fields or the bursts of pulsars, that radiowaves can increase the power of the signal, which means that it can come from a very long distance like from another galaxy, and maybe the origin of that signal remains a mystery forever.
