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. 



“Electron microscopy revealed chain structures resembling living organisms in meteorite fragment ALH84001” (Wikipedia, Allan Hills 84001)


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. 



The Artist’s impression of an alien city. 

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.

Is reality exists?

  Is reality exists? 


Does the subjective experience make reality more or less exists? In some models, reality forms in the future, and at the point where we and time flow crossing, reality turns things that we can observe. Everything that we see happens in past. The time that photons take to travel from 200 meters away is minimum. But even in that kinds of cases, we see things that happen in the past. Things like fog and other disturbances affect information even in a short moment. 

The information that we get is not identical. The position and other things between two observers affect their way see things. Different experiences also affect people's feelings. And those things affect the way to see a thing. When two people are standing near some object and another of them has a strong negative experience connected with that object, that person sees it differently than the person whose experiences are neutral. 


Reality is a subjective experience. 


Reality is one of the things that we don't know. We know that something exists. Things like electrons are well-known things. But we cannot see that thing. We read those things from the net and books. 

Things like our personal experiences are modeling our relationship with reality. When we see something we cannot be sure, does some other actor got the same feelings about it? All our senses participate in forming of reality that we sense. But there are different ways to see things. 

In some models, reality is an illusion. That is formed in our brains. We know that absolute reality does not exist The position and senses of the observer determine how we see reality. And the ability to communicate between observers also limits sharing of information. If we are not telling everything to another person something is missing. 

So how can we say that another person feels and sees things the same way as we see them? And even the best description cannot transmit the entirety of our feelings to another observer. Full entirety means that we can transmit also things how we feel about those things. Sense of touch and sense of taste is hard to describe. That means we cannot feel and taste everything the same way. 


The AI can answer questions. But it doesn't realize what it answers. 


That thing makes AI problematic. If we ask for something kinetic or absolute from the AI that thing can tell many things about that thing. Kinetic things are like the technical details of Formula 1. The AI can tell colors and engine horsepower. But things like opinions, for example, which one is better, chicken or vegetable hamburger, or do you like heavy metal or classical music cause problems to AI. The reason for that is that AI doesn't have an opinion. 

The AI can say that it cannot tell opinions. But the problem is that the AI follows algorithms. Algorithms are program codes that describe how the AI must act in certain situations. So if the AI doesn't recognize the question about opinions it can start to find the answer from the net, by using certain parameters. And one parameter can be which pizza or which music gender is higher in order or listen to list. 

So the situation is similar as we will ask people which is the best hamburger, and then we can say that the best hamburger is the hamburger that is the most often bought. In that case, we can make elections and vote on many things, but that thing doesn't tell anything about our personal opinions about that question. 

The fact is that the AI cannot detect if the information is false. If somebody hijacks the sensors that the AI uses that thing means that AI cannot detect data coming from the camera or some other source like a high-resolution screen. 


There is no true or false data. There is only data. 


When we handle data. We must realize that our brain doesn't know if data is true or false. The thing is that data itself is just data. That means our brains and consciousness don't automatically suspect data is false or true. These kinds of processes are the result of training. 

When we see the object created by using a hologram machine, we can say that the object exists. It exists as a hologram. In that case, we have no responsibility if we describe the object as reality. If somebody introduces a hologram as a real object. And we cannot touch it. We have the right to believe that object is real. 




There are two images in this text. I took those images in the same place and the same place. The focus in those images is adjusted differently, and that makes those images different looking. The purpose of those images is to demonstrate how the difference in senses affects how we see reality. 




Lots of existence is out of our ability to observe it. 


An object is a reality in the form of a hologram. As I just wrote. But then we must realize that the reality. What we see is only a small part of our existence. We see only a shell of material. Nobody has ever seen the nucleus of the atom without extremely advanced systems. Same way as we see only a small part of icebergs. We see only a small part of the electromagnetic spectrum. 

So that means there are lots of things that we can never observe without equipment like infrared or X-ray telescopes. Every year we find another part of reality. Reality does not exist in absolute form. We know that we see something, and the same way things, like insects, see something. But then we must ask: does the insect realize what it sees? 

In the insect's brains is two modes: hit or run. If an insect sees something it recognizes the object. If the object is food or a partner the insect goes near it. And if an insect sees something else it escapes. But in our brains is many other possibilities. Reality is something interesting to us. We might see many things, but because we don't always react outsiders cannot see, what we see. And another thing is outsiders cannot see how our brains modify things that senses bring to the cortex. 



Plato's cave is an example of selective information. 


Plato's cave is an example of selective information. Or brains are always selective because their capacity is limited. And they select things that they store. Everything that happens to the carrier of those brains happens just to that individual. 

This is the thing that makes every experience unique. If we see that some other person falls we cannot feel that thing in our own body. That's why we always react differently to things that happen to somebody else than we react to things that happen to us. This is why all experiences are somehow subjective. 

Reality is always subjective. If we would spend our entire life in some room and VR (Virtual Reality) masks are on our faces, and we ever go outside. We can think that reality is what we see on those screens. If we spend all our lives in one room, we can think that everything is like in that room. That room is our entire world. 

We can make that room a virtual reality without any VR systems. If we ever can go outside and we cannot see anybody else than some servants, all the information that we can get depends on what those people are telling us. 

The fact is that this is a high-tech version of Plato's cave. In that model, somebody controls everything that we see. The Internet could be the big Plato's cave if we just search for information that pleases us. If somebody covers the entire planet by using screens that allow that actor to deny that there are no other things in the universe except that planet. 

The thing is that even the biggest of Plato's caves are. Places where people get subjective information. People who use the internet are easy to blame for that thing. But even if we travel to distant countries we can select the information we want to see and feel. We can go to some country and then sit in a taxi or tourist bus and spend all time in a hotel. Would we get the right or diverse information about the country?

Could there have been UFOs in Earth's orbit in the 1950s?

Aligned, Multiple-Transient Events in the First Palomar Sky Survey could be artificial objects. Or. They could also be some light reflection...
