Why must we search for other extraterrestrial civilizations?

At the beginning of this text, I must say that not all alien life forms are probably intelligent. Most of the alien life forms that we can imagine or predict are bacteria. There is a possibility. That some bacteria or viruses can survive interstellar travel. That means their genetic material remains in a condition that it can transfer into the cells of Earth organisms. 

A virus is a protein package. There is genetic material. And that thing can survive in the freezing cold of interstellar travel. The gamma- or X-ray bursts can destroy that genetic material. But otherwise. The space between stars is very stable. It freezes genetic material almost forever. 

There are no certain observations about the alien civilizations. So, we have no confirmed observations about those still hypothetical aliens. But when do we detect them? We don’t know. But. That can happen tomorrow, or it can happen after 1000 years. 

But then, to the intelligent lifeforms. Why should we continue the Search For Extraterrestrial Intelligence (SETI) program? Because there are billions of stars in our galaxy. And there are billions of galaxies in the universe. Somewhere there must be alien civilizations. And the SETI program ends in the day, when we see that civilization. 

Here I must say one thing. Even if SETI finds another civilization. That doesn’t mean that we make contact with that civilization. This is one of the things that people must realize. But. Confirming the existence of another civilization is very difficult. 

There are a couple of so-called breakthrough listen candidate signals. Those signals are. So-called Wow! and the Alpha Centauri signals. Those signals are unique, and we don’t know how long they lasted. We know only the part of those signals that the radio telescopes captured. And that is one of the things that we must realize. The thing is that those signals happened only once. Supporting the model that they were synthetic. 

If we think that the origin of those signals is in a natural source, that means they should repeat.  But. There is a possibility. that their origin was in the reactions as the Gamma-ray burst traveled through the plasma of some star’s flares. There is a possibility that a very rare natural effect causes those signals. But. As we know. The universe is a strange place. And. It's possible that the fast energy pulse travels through plasma fields. But as we know, we must only guess how long those signals lasted. And because there are no other similar signals, we must only guess whether they are synthetic or not. 

So, why have aliens not contacted us yet? The reason for that can be that they don’t detect us. Even if we send microwaves. And radio signals all around us, we must realize that. Those signals traveled for less than 200 years. 200 light-years is quite a short distance in the scale of the Universe. 

And when we look around us, and look at things like the closest stars, we can see that we are surrounded by young stars. Sirius is the brightest star in the northern sky. Sirius is a binary star system, and the brighter component of that system is only 230 million years old. Sirius B is a white dwarf. That was once a Sun-like star. Components of that star are formed in different places and at different times. And once in history, gravity locked those stars together. If Sirius B had some kind of planetary system, Sirius A would destroy it. 

Things like mature red dwarfs can also be more suitable harbours for life than we think. A red dwarf can exist as a star far longer than the Sun. If we think that the Sun will stay. As a yellow star for about 7-10 billion years. The red dwarf can exist as a star for about 11 trillion years. The young red dwarf has a hyperactive period. Just like other young stars. Then, after the hyperactive period, the red dwarf’s planets can turn into the harbours of life. That period starts later than in the Sun-type stars.  

But it takes longer. The fact is that most of the red dwarfs near our solar system are young. The age of Proxima Centauri is about the same as the Sun's. And Wolf 359 is about 0,1-1,9 Gyr( Gigayear(10^9, or Billions of years)). The third remarkable red dwarf, Barnard’s star, is about 10 Gyr. This can explain why there are no civilizations near us. The only star system that is the same age as our sun is the Alpha Centauri system. Those stars (Alpha Centauri A, B, and Proxima Centauri) are all about the same age as the Sun. 

Another thing is that. The alien civilization might not hear us. The universe is full of radio sources. But the thing is that. We don’t know what those aliens look like, how they communicate, or where they are. We don’t know anything about their culture. And we certainly hope that we detect them before they detect us. The third thing that we can hope for is that the alien civilization is not as destructive as we are. But. If we someday detect an intelligent civilization, we must carefully think. About our next step. We must realize that those aliens can be hostile. But when do we detect them? As I wrote many times. That can happen tomorrow or after 1000 years.

Writings about things, what are actually opinions. (Fermi's paradox and Drake equation)

https://gamesandtehories.blogspot.com/ 

Kimmo Huosionmaa

There are people, who do not understand one thing when we are writing something, we have the right to tell our opinion about that. And one of the things, what seems to cause very strong feelings are writings about SETI (Search for Extraterrestrial Intelligence) and aliens. Writings about those things are actually opinions. When we are writing about some kind of extraterrestrial civilizations, we are always facing the Fermi's paradox and Drake equation where that physician or astronomer calculated his famous formula, that if the known habitable civilizations are the division with the known planets, we could get the percent of planets, where are civilizations.


When we are thinking about Drake's formula, we must ask why this man didn't make it more simple to understand.  The number of known civilization in time when Drake wrote his formula was one. And the number of known planets was nine because Pluto was a planet at that time. So the Fermi paradox and Drake's formula should go was in that time 1/9*100. Now this formula goes that the number is very much lower than in Drake's time. And the Fermi's paradox is always connected with Drake's formula. In the real life, Drake's formula is more complicated than this formula, what I wrote here.

And in this case we are facing the truth, that everything when we are thinking about that paradox we are facing that we are writing about opinions of that formula. When we are discussing with the doctor of philosophy about that thing, we must realize that this person would always win us, by claiming that we would find another civilization after 100 years. Every time when we are talking about extraterrestrial intelligence, we are talking about our own opinions about that question. We always forget that extraterrestrial life form could be some kind of vegetable. Even if the planet is covered by vegetables and forests, that would not actually mean, that there would be animals at all, and this is the very interesting thing.


When we are thinking about aliens or some intelligent life form, we are forgetting that the "alien" can be created by the human by connecting the genomes of animals to human DNA, and that makes possible to create alien in the terrestrial laboratories. Aliens are the very interesting object for discussions, but when we are thinking about the shape of those strange forms, we might think about the person, who thinks with the different way than other persons.



So in this case, we might think the alien some kind of individualist, or something, what we could ever imagine. When we are thinking about reptilian hybrids, we could face the creature, what would be easy to follow. If that creature makes the things in some secret organization, that thing would ever give any information to unauthorized organizations. And it would not officially exist, what makes it easy to control. In this case, the scientist would create the creature for making secret missions for the governments or private corporations.

Interesting theory that maybe we are alone in our galaxy

(Picture 1)

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.

The problems of SETI-program

Kimmo Huosionmaa

SETI (Search for Extraterrestrial Intelligence) program is one of the most dangerous programs in our planet. Even if we haven't get contact or signal from extraterrestrial intelligence, the telescopes might get it in next night. Or they can get contact beyond 1000 years. Some people think that waiting for a contact is like waiting for a train or something like that. SETI program is not so simple because we can't know when the first message is coming.

Or does it come in our lifetime? When we are talking about that project. If we will get the signal from other civilization, but we might ever take contact to those civilizations. They might be so far there, that we ever can't message together because the civilization might be in Andromeda galaxy. That proves the existence of alien civilization, but that doesn't mean that this civilization has ever meanings for us. That civilization would be so far, that even if they jump in their UFO:s right now, our sun would be turned a red giant before they arrive.

Problems of SETI program is that if we will get contact to other civilization, we might get under attack. But if we use the right technology we can hide our existence from aliens. We can cover our entire planet holograms, what makes humanoids to believe that our civilization does not exist. And of course, radio telescopes might use as a gigantic ECM-system, what makes our planet seem like there will not find any interesting. The system will be sent back waves to humanoids transmission, that they can’t see our planet's surface with radar and they can’t get repulses in their telescopes.  

That radiation makes the radio waves or their echoes weak, that they can’t go back to the transmitter. Or otherwise the signals what will be sent back to humanoids would be so powerful that they would think that this will be gigantic super earth, there will be no life forms exist. But this scenario is pure fiction if published information is true.

But everybody knows that federal authorities are not talking true all the time. SETI is one of the most complicated missions on Earth science community. If you want to investigate extraterrestrial civilizations you have nothing where to start. There is not even one single message what is proven that is coming from another star. If somebody believes extraterrestrial intelligence, that does not mean that he or she believes little green men, or why that person wouldn't believe that some people might have green skin. There is one great “if" in those scenarios.

If somebody has put the genetic what causes photosynthesis in the flora to human DNA, that will make the human skin transformation to green. But what kind of technology that speculative humanoid civilization might have. They might have the technology to create “wormholes", but the problem with wormhole travel is that that kind of stuff will need two black holes, what will put resonate to same frequency, and after that those black holes must be separated and another will pull to the place, where that civilization wants to travel. That will take very long time for that civilization, and success of that project can see until the trip is done. That’s why aliens must be sure that there is something interesting.

Otherwise, the trip is made for nothing. And it can take even thousands of years. But there is always artist’s freedom to use imagination about other civilizations. They might have gigantic Dyson spheres, where could be floating “island” in the middle of that colossal ship, what might be the size of a planet. That island would be in the area, where is not gravitation field, and that area might use for production, what needs absolute zero-gravity condition. There might be nano-technological and biotechnological research areas, where they create nano-robots and other that kind of stuff.
