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.

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.

Dream of 15 min. towns. Can we make everything in 15 minutes?

Everybody knows the dream of 15 min. towns. In those towns, every service is 15 minutes trip away from home. But can we escalate that dream? Could 15 minutes city or 15 minutes urban area involve the idea that every service will happen in 15 minutes?

How realistic this model that everything happens in 15 minutes is? And could the most modern technology turn the global environment into 15 minutes entirety, where people can reach everything on Earth in 15 minutes? 

That means we would go to the doctor in 15 minutes. We are waiting for the doctor for 15 minutes. And then we spent 15 minutes in the examination room. After the doctor, we go to the drugstore in 15 minutes and after 15 minutes. We have medicines in our hands. Could that thing be possible someday? We can call that vision the 15 minutes society. Everything happens in 15 minutes. 

When we are building taller buildings. The reason for that is that price of land is high in urban areas. And we can make hybrid solutions for an environment where people are living in smaller areas. And shopping centers are connected to houses where people are living. That makes the use of time more effective. 

And when those complexes are ready that solution decreases emissions. But the problem is that people might not ever go outside. And in the most extreme dystopic visions, those shopping-center-home hydrides are turning to independent states. 

Maybe shopping centers are the service centers of tomorrow. And if the robots are making physical products people can work in the same building where they live and go shopping. There could also be things like public services like doctors. But of course, this kind of advancement means that people have fewer contacts with the outside world than ever before. 

If we have the internet. We can click ourselves to another side of the Earth. Of course, we are not physically in there. But we can use VR screens that are giving us a real-looking vision of the environment. But the problem is that we are selecting information. We must not read things that do not please us. And that means we are missing the information that can be vital.

But can we travel physically around the world in 15 minutes? Or travel to any place on Earth in less than an hour? 

When we think about things like hypersonic aircraft and hyperloop trains those things might transport us to any point on the Earth by using hypersonic transportation. New hypersonic systems use hydrogen fuel so they are not causing emissions. And the hypersonic VTOL (Vertical Take-Off and Landing) aircraft can take people to any location on the Earth in less than an hour. 

But the "magnet loop" train could be a more powerful and faster transportation system than any other transporter invented before. The magnet loop is a particle accelerator that transports the train inside the vacuum tube. 

The system uses magnetic levitation. And also magnets are pulling the train in that tube. Because there is a vacuum in the tube there is no friction. And that allows rising the speed of that system to be highly hypersonic. That kind of system can make it possible to make a new type of transportation that is faster than any atmospheric system before it.

If the source of gravitational waves is solved someday, that opens incredible opportunities.

Gravitational waves are wave movements like light or radio waves. That wave movement is hard to detect. Because a gravitational wave is quite a weak effect. But if researchers can create synthetic gravitational waves someday. That opens incredible opportunities. That makes it possible to create the tractor ray that can move at least a single atom. And that thing makes a revolution for nanotechnology. 

The synthetic gravitational waves can make it possible to create the gravitational rocket engine. The gravitational rocket uses the gravitation waves fro create thrust. But the requirement for those systems is the ability to make synthetic gravitational waves. 

The source of the gravitational waves is interesting. The thing about gravitational waves is that those things are some kind of wave movement that travels around the universe. The wave movement doesn't form from emptiness. And the source of the gravitational wave is interesting because if that source is known. That allows the creation of synthetic gravitational waves. 

There are two possibilities where the gravitational waves are forming. 

1) They are forming of the oscillation of the yet-unknown particles. 

2) They can form when the electromagnetic radiation impacts other electromagnetic radiation. So the impacting wave movements can be the source of the gravitational waves. 

The researchers have used pulsars for detecting the gravitational waves. The gravitational waves are affecting to radiation of pulsars.  And the question is what part of the supermassive black holes is forming those waves that are extremely hard to detect. 

If the source of the gravitational waves is in the wave movement that surrounds the event horizon. That thing would make it possible to copy those conditions to the laboratory. The thing is that the gravitational waves are forming whenever the particles are impacting. 

But normally, those waves are too weak to detect. And only black holes can send the visible gravitational waves constantly. 

Sometimes researchers introduced. That gravitational waves source would be in gluons between quarks in the protons and neutrons. That means the gluons or the gluon channels between the quarks would oscillate like the guitar language. And that wave movement would be the thing called a gravitational wave. 

The theory goes like this gluons, the transportation particles of the strong nuclear force would form the channel between quarks, and in those channels or between quarks is the electromagnetic vacuum. That electromagnetic vacuum causes that "quantum vacuum" will suck the quarks together.  If the source of the gravitational waves is the electromagnetic field or channel between quarks. There is the possibility that someday those channels can create in laboratory conditions. 

So maybe someday we could create the free quarks that can be stabilized. And maybe researchers can create the stable quark superposition someday. But when we are thinking about gravitational waves. If the source of those things will recognize. That thing would make it possible to create the "gravitation laser". The gravitational laser would be the real-life tractor ray. But the great question is, how strong that thing could be? 

The gravitation laser or coherent gravitational wave would make it possible to move single atoms on the layer. But for creating that kind of thing the researchers should find the source of gravitational waves. 

The synthetic gravitational waves are the thing that makes it possible to create the gravitation engine. The gravitational rocket system uses gravitational waves for creating movement. But those scenarios are far away in the future,
