Alien civilizations again and again.

  Alien civilizations again and again.

There is a possibility that NASA’s Perseverance rover found some kind of bacterial remnants on Mars. There was an ocean in the northern hemisphere. Then the planet froze, lost its atmosphere. And then the UV radiation destroyed the water. The reason for that can be the lack of a magnetic field. It’s possible that the chaotic magma structure explains that thing. When Mars faced its last catastrophe, the impact could break its core. And that caused the loss of the magnetic field. 

And then to aliens. 

This discussion begins every autumn. Are we alone in the Universe? The answer is this: until aliens call, we are alone. The only fact that we have is that nobody answered. Or nobody made contact outside Earth. Or there are no confirmed alien technosignals. This means that we might be alone in our galaxy, or there can be one or more other civilizations. And maybe some civilizations are already destroyed, because they failed the ultimate test. That failure can be the civil war. 

Or it can be an overestimation of one's own technical skills. In some models. Pre-Kadashev-scale civilization can test things like an antimatter rocket. And then there will be some leak in the capsule. That causes annihilation that can destroy the entire planet, in this case. The civilization that reaches the Kardashev-scale 1 starts to build an antimatter rocket that can give them access to the entire solar system. Then there is a leak in the antimatter capsule. But then. We must realize a couple of things.

When we talk about aliens. First, intelligent aliens are different from techno-aliens and primitive life forms. A water planet can host lifeforms. Those lifeforms will not be intelligent. Those lifeforms can be something that lives in their seas. Those creatures could be some kind of bacteria. Or algae. Another thing is intelligence. Without a certain type of atmosphere, that alien race cannot make fire, and they require that skill to  melt metals. There is a possibility that the first humans melted metals in volcanoes or lava. But this method uses a natural heat source. It is not as simple a method for melting metals as using fire. 

As the fire that those aliens can make using matches or friction. Intelligence doesn’t mean that a creature turns technical. Or it can form a technical civilization. If the star that they orbit is too heavy and too bright. That makes the star too short-lived for the creature to form anything technical. Also, it's possible that the black holes or some nova or supernova explosion near the civilization’s own star sterilizes their planet, or there is a possibility. that their own planet is metal-poor. That means there are no metals. There are millions or even billions of things that can go wrong before civilization can fly to the stars. 

The planet can travel too close to Sagittarius A, and near the center of galaxies, the radiation can destroy those planets. There is a so-called habitable area in a galaxy. And at that zone, stars are mature enough that planetary systems can form around them. Those planets must be solid, and their trajectories must be stable enough. There must not be a large number of roving pieces. Those pieces can destroy the planet and its lifeforms.

And that civilization requires the will to make technical things. Without motivation, those creatures will never fly to space or stars. Or without the need, evolution will not favor things like intelligence. Without catastrophes, the creatures will not rise out of the oceans. They will not require brains or high-level intelligence. 

The locked planets around K-type stars might not be suitable for lifeforms. But those locked planets can offer a place for a technically advanced civilization. To make its stand. That thing means that a locked planet offers unlimited solar power to that civilization or its base. Those creatures can use protective suits and live under domes that help them to protect themselves against those red dwarfs' flares. That kind of case requires. The red dwarf is quite close to the alien solar system, or orbits it. Sometimes we should ask what our technology looks like. If we had a red dwarf at the same distance as Proxima Centauri orbits Alpha Centauri. 

The fact is that Earth is the only planet with confirmed lifeforms. But it’s possible. That there was some kind of microscopic life on Mars. Before that planet froze, lost its atmosphere, and the UV radiation destroyed water molecules. 

There are some stones that support the Martian lifeforms.  Their problem is that they were found on Earth. The Allan Hills 84001 (ALH84001) meteorite from the South Pole involves structures. That could confirm life on Mars. But the problem is that those bacteria-shaped structures can have an origin on Earth. The South Pole is not cold enough. That it could keep that meteorite sterile. There is a possibility that those. Probably lifeforms that left their markings on the shell of Allan Hills 84001. It can come from Earth. Maybe those primitive creatures felt the heat of that meteorite. And traveled to it. Those strange forms look like primitive creatures. Like rod-shaped cyanobacteria or small tubeworms.

The question of life in the cosmos is more complicated than we even thought. NASA’s Perseverance Mars vehicle found promising structures on Mars that look like bacteria or their remnants. The thing is that. Those forms in stones look like bacteria, or their remnants. But that doesn’t make them bacteria. But as we know. Perseverance found a sign that could be the first sign. Or strong evidence of life on another planet.

So they might not prove anything. In one way or another. The problem is that even those things can be some kind of bacteria. They can arrive from the Earth, with some meteorites or with probes that are not properly disinfected. 

The biggest problem with alien hunting is that nobody has officially seen aliens. There is no confirmed alien DNA. Or confirmed alien cells. This means researchers cannot even know. What they should try to find. Searching for an alien civilization is not searching for a needle in a haystack. It's more difficult. There are as many variables that make models for techno civilizations, or their location is impossible to determine. The techno civilization can be something other than we think it is. Even if those civilizations use microwave ovens, we might not detect those signals. Or maybe we don’t separate those signals from natural microwave signals. We don’t even know if they use radio as data transmission. Or maybe those other civilizations do not exist. 

Existence is a remarkable thing for those civilizations. The civilization that doesn’t answer does not exist. And maybe we don’t want that answer. There is always a possibility that those civilizations are too far away that us cannot hear their radio signals. Another thing is that we are between the Milky Way’s spiral structure. That means we might be a cosmic Eastern island. And maybe we are lucky.

Are we already found alien life?

"Small part of the Cydonia region, taken by the Viking 1 orbiter and released by NASA/JPL on July 25, 1976". (Wikipedia/https://en.wikipedia.org/wiki/Cydonia_(Mars))

Some researchers suggest that maybe we already found alien life or evidence of even intelligent lifeforms. But we judged them false too quickly. And then, if the falsification happens too fast, it's hard to change the testimony. But the fact is that the evidence of the suspected ancient Matian lifeforms is not found very often. 

And that is evidence that supports and denies the hypothesis about ancient primitive lifeforms on the red planet. The suspected bacteria fossils on a meteorite found in Antarctica look like cyanobacteria. So their origin can be on Earth. 

Somebody says that we already found evidence of intelligent life. In some theories, the "face of Mars" are created by nanomachines that can imitate things that they see. And some other people think that the famous image that is found in Wikipedia is from some underwater platform. 

Image 2) "Electron microscopy revealed chain structures resembling living organisms in meteorite fragment ALH84001" (Wikipedia/Allan Hills 84001) ALH84001 means Allan Hills 84001)

When we think about the Viking experiments in the 1970s there were some incoherences in samples that Viking landers analyzed during their operational time. That thing caused suspicion that there could be some primitive lifeforms on Mars. But then all those pieces of evidence were falsified. And after that, there has been some kind of discussions about the messages or signals captured by the SETI program. 

There was evidence that are against and supporting the theory that those BLC 1 and Wow!-signals were artificial. And the best thing that supports that theory is that those signals happened only once. The BLC 1 came from the direction of Proxima Centauri, but the origin of that signal is unknown. 

The Proxima Centauri's direction doesn't mean that signal comes from Proxima Centauri. There is also a yellow, sun-type star in another direction where the "Wow! signal could" come. The distance to that star is over 3000 ly. 

But why we are overcritical? Why is all evidence that are supporting life on other planets denied? The thing is that some people are thinking that "little green men" are a joke. We always forget that genetic engineering can make it possible that even humans can have green skin. Green skin can have chlorophyll in its cells.

And that allows the skin of the creature can create the same sugars as vegetables. So are the "little green men" some kind of joke? The thing is that genetic engineering can hybridize vegetables and humans. And that thing causes interesting thoughts in my mind.

Why hasn't ET phoned yet?

The big silence: why don't ET phone us?

Could aliens believe that our planet is in civil war? Or are they using some radio frequencies that we cannot hear? 

Element 116 or (Livermorium) hypothesis

Why don't aliens make contact with us? If an alien civilization uses synthetic, ultra-heavy radioactive elements like element 116 (Livermorium) as crystals in their radios oscillation circuits. That makes them able to communicate longer distances without interference. That model makes it hard to hear those radio signals. 

Because their transmitter's oscillation circuits cannot make our receiving circuits oscillate we cannot see alien transmissions. The super-heavy synthetic elements make it possible to communicate over longer distances. 

But those super heavy elements create different frequencies than we use in our radio systems. That makes it hard to see those hypothetical alien signals. 

If we think about alien communication. We should realize that their communication is meant for themselves. Not for us. 

There is a possibility that alien civilizations use neutron balls or some extremely heavy and short-living isotopes like element 116 (Livermorium) as the oscillation crystals in their radio systems. Element 116's existence is less than a second. 

Sometimes it's planned to use in some ultra-secured communication. The use of synthetic isotopes makes it possible to create synthetic radio frequencies that are less vulnerable to interference. But using that kind of synthetic isotope requires that the system dilate time. 

Could aliens believe that our planet is in civil war?

There are writings on the net, where somebody tried to explain cosmic silence. Why doesn't ET contact us? And there is one aspect that nobody mentioned. The aspect is that maybe aliens think that our planet is at civil war. 

When we think about the SETI program and alien civilizations we have one thing that we should keep in mind. Being civilization the aliens must reach Kardachev level 1. That means the alien must solve their internal problems. And that is the end of states in the form we know them. 

So only if aliens are living in a giant planet-size state that they could conquer their solar system. If we think that civilization lives on a planet that orbits a yellow star the solar system is huge. If they want to make bases on other planets that require lots of resources.  And that means aliens must have economical and political support for that kind of project. 

If aliens are forming a homogeneous civilization. There are no national states they might see that our planet is in civil war. In that hypothesis, the key element is that the aliens don't want to choose their side because they are afraid that they rise dictators in power. So they want that we solve our problems before they show themselves. 

This is one aspect of the SETI- program. We know that there are billions and billions of galaxies in the universe. If we seriously think that we are alone even in our galaxy, we are a little bit too lucky. The question is: why we cannot see alien civilizations? One of the answers could be that those civilizations use some other method for communicating than radio waves. 

Radio signals from another civilization are the best way to see technically advanced civilizations. But the problem is that the SETI doesn't find those radio signals. The answer to that question could be that cosmic radio sources like neutron stars and radio galaxies cover those signals. Or maybe aliens use frequencies that are impossible to hear from Earth.
