Search for Extraterrestrial Intelligence, SETI, and mathematics.

“Exoplanet Kepler 168b An artist’s impression of the rocky, habitable-zone exoplanet Kepler-168b. Credit: NASA Ames/NASA/JPL–Caltech/Tim Pyle (Caltech)”(ScitechDaily, The Nearest Alien Civilization Could Be 33,000 Light-Years Away)

“New research suggests that technological civilizations in the Milky Way are extremely rare, with the closest potentially 33,000 light-years away.” (ScitechDaily, The Nearest Alien Civilization Could Be 33,000 Light-Years Away)

The closest civilization could be about 33000 light-years from Earth. That means it's very unlikely. That aliens make contact with us. 

The Search for Extraterrestrial Intelligence (SETI) tries to map the Universe and find an alien civilization. The closest civilization could be about 33000 light-years from Earth. That calculation is used to calculate the average distance between 33 points. That spreads evenly over the Milky Way-sized disk. Nobody made contact with an alien civilization, at least officially. So. Everything that is written about the aliens. Have hypothetical backgrounds. 

There is a possibility that people really saw the silver-suited small men around some capsules. But those things might be robots. That origin is in the Lockheed-Martin laboratories rather than in outer space. The origin of the aliens and UFOs can be in some. More or less secretive research and development programs that originate in the Pentagon or some other authority, or in some defense industrial platforms. 

But if the next model is true, we should not worry about alien contacts. But if we get in contact, that means that we should be very afraid. The best possible distance to an alien civilization is 23140ly, if we calculate that the Milky Way’s diameter is 150000ly. In that case, there would be 33 intelligent civilizations in the Milky Way. In that purely theoretical model, those civilizations are evenly spread across the Milky Way. I used Gemini AI to calculate the average distance between 33 points on the Milky Way-sized disk. But there is more. About that thing later. 

Telescopes still wait for the signal from other civilizations. The SETI program has given. Lots of data about exoplanets. And has given a new data matrix and mathematical models for. How to separate and analyze weak radio signals. And separate them from the background. This program advanced the network-based calculations that made the large language models (LLMs), or AI, possible. The only thing that SET is not found is an intelligent alien civilization. 

SETI tries to find alien radio signals. It tries to find signs of pollution. And even a visual technosignature. Like cities from exoplanets. Those cities are hard to find, even if they are quite close to us. Those cities can be found by calculating what the luminosity of the planet’s dark side should be. For that, researchers should know what kind of surface the planet has. Then, if the luminosity is higher than it should be. That is the sign of an intelligent civilization. Or it's the sign of the very active volcanism on that planet. 

Another interesting thing is that the city itself doesn’t need atmosphere. There are models that intelligent aliens could create city-sized bases. Those are under the domes. And in that hypothetical model. The locked planet can give a perfect place for that kind of place. The base itself could be on the dark side of the planet. And on the sunny side could be the solar panels that deliver energy to that large base. That hides under pressurized domes on the dark side of the planet. This location protects that thing against the star eruptions. 

Those planets with no atmosphere can be perfect platforms for technically advanced civilizations. There are no original lifeforms on those planets. And that planet’s locked position offers the perfect place for the solar panels that harness energy from the sun. The dark side offers perfect safety for those bases. The residents of those bases can create an artificial atmosphere under those domes. But that thing is only a hypothetical model. About the advanced alien civilizations. 

AI-made impression of an alien base on a planet that has no atmosphere. 

There are models that suggest that there are 33 intelligent civilizations in the Milky Way. That feels very good to find an alien civilization. But if we think that those civilizations are evenly distributed in our galaxy. That means the average distance between those civilizations is 30853 ly. If we calculate that distance using the Milky Way’s diameter of 300,000 ly. 

And if we use the value 15000 ly. for the Milky Way diameter, the average distance between those civilizations would be 23140 ly. Those numbers are taken from Gemini AI, which got the mission. To put 33 points that spread evenly on the Milky Way-sized disk. The system introduced two values for the size of the Milky Way. Those values were 300000 ly and 150 ly. 

That means there is a very small chance of making contact with an alien civilization. The fact is that our radio transmissions do not even reach those civilizations. If we think. Heinrich Hertz's radio experiments in 1886 were the first radio transmissions. Those radio signals are spread to 136 ly. away from Earth. That means the closest possible civilization is far away from that bubble. 

And in that case, we must think that no side effect or disturbance covers those first signals. But if we think. The distance to the closest possible civilization is 23140 ly. And the size. The radio transmission bubble is 136 light-years. That is a ridiculous distance. This means that the alien civilizations are. Lucky for us. A very long distance from us. 

If those hypothetical civilizations sent a signal that arrives tomorrow, that means those signals left. Minimum 23140 years ago. And if we receive that kind of data transmission, that means the alien civilization is very old. And maybe that explains why we don’t get a message. If those aliens that sent their first message to Earth 12140 years ago. If the Milky Way's diameter is calculated to be 150,000 ly. Might follow the protocol of responsible scientists. They might not want to teach us. Everything about their technology. 

They might think that maybe it’s better to let us advance before they take contact, or maybe. Those hypothetical civilizations will not hear us. The reason for that is that our signals don’t reach those civilizations. If those aliens handle the wormhole-based communication, where qubits will transport through the wormholes, that means they don’t hear our signals. 

And there is a possibility. The wormholes allow only for sending the qubits or quantum communication through them. It’s possible that we will never meet another civilization. If we put the 500-year limit for “never”. And even if we put 1000 years, our signals will not yet reach the closest civilization. So, as always, we are alone until we get an answer. That moment will be the biggest thing. In human history. But when that happens? Nobody knows. And after that, we must be prepared for everything. 

Artist’s impression of the surface of the locked exoplanet. That could be Proxima Centauri b

But researchers. And mathematics gives only models. Of the alien civilizations. We don’t know anything about the other civilizations. All information. What we have is actually hypothetical. Researchers think. The Earth is not so unique. As we hope that it is. Latest findings on the planet Mars support the idea that life itself exists. It can be quite common in the universe. But intelligent lifeforms are very rare. There is a possibility. That there is another civilization. Or even many civilizations. But they are meaningless to us. This means that the alien civilization can be so far away that they cannot interact with us. The first contact will be the end of something in human history. That will be the moment. That we fear and we hope. As has been written many times. 

That contact can happen after 1000 years, or it can happen tomorrow. After that, we must be prepared for everything. We don’t know those aliens, or we don’t know anything about their culture. If or when we detect the alien signal, we must carefully think about the next step. If an alien civilization is too advanced, it can simply detonate us by accident. If they create the black hole machines that can transport passengers between stars in seconds. 

That thing can destroy us. If those aliens want to discuss with us, they might want to make the teleportation channel between them and us. If we don’t handle that technology, the black hole can destroy the entire planet. There is a possibility that aliens use too much power in the data transmission, and that can cause a massive solar eruption that destroys Earth. Those are things that can happen if we advance too fast. If aliens give us something. That thing can cause a situation where the system they give causes a very big detonation.

Why is it hard to impose sanctions on Russia?

    Why is it hard to impose sanctions on Russia? 

We always wonder why Trump hesitates to impose sanctions against Russia. The reason for that is extremely complicated. We know that the Russian government has large-scale nuclear weapons that they use as blackmail tools. That is an easy explanation. There is also another problem with Russia, and that problem is China. China is the biggest producer of rare earth metals. In the world. Even if the USA is one of the most powerful and advanced countries in the world. That country is bound in the international, global-scale raw material network. 

And that thing puts the brakes on the U.S. government. The USA has been the most advanced microchip maker on this planet. But the problem is that. This country requires many strategic metals and minerals that are used to make microchips and other technical equipment. This means that if China does not deliver those minerals, the USA’s ability to produce microchips decreases. Another problem is things like oil. Many oil producers in the Middle East are BRICS countries. Those countries want to see Putin as their ally. The reason for that is that those nations are non-democratic, and the activist movement wants to limit weapon sales to those countries. 

Those people know that Putin is not as sharp as Western actors who use those weapons. And Putin can sell things like nuclear weapons technology to those countries whose main source of income is minerals, and especially the oil and gas industry. The U.S military requires oil and gas for its global operations. The nuclear bomber can operate on a global scale using airborne refueling. But the support operators.  Like special forces teams. Need petroleum for their equipment, in case the nuclear bomber must make an emergency landing. Those operators also require a base in the Middle East where they can operate. In those situations. 

Another problem is that Putin thinks that he can try to buy politicians and other people to support his propaganda. People know. That Putin and his regime are willing to make sacrifices to stay in control.  The fact is that those sacrifices don’t touch Putin’s nomenclature. And that is the thing that is a big problem. Another thing is that nobody knows how big a sacrifice Putin is willing to make. Putin is the man who is in command. But he is not the entire regime. There are people in Russia who support his policy. That means changing the leader might not mean that war ends or anything changes in Russia. 

There is a certain cycle. When we think about the freedoms in the Soviet Union and Russia. There are always thaws when new, young leaders take their position. But when leaders turn old. The secret police will start to tighten its grip on society. That means arresting and sending to the GULAG. When the leaders change, the people who served those leaders turn into criminals. In one night. After Stalin’s death, his loyal servants like Beriya and many other people went to prison and were executed. That was the second purge. Those purges followed all other soviet leaders. And they still continued. The idea is that people who served the old regime are useless. And the new leader collects a new regime around him. 

The thing is that the secret police controls the entire society in Russia. If leaders are not pleasing the secret police organization. That person faces a heart attack. As long as the secret police exists, there cannot be big changes in the Russian government. The secret police surrounds all Russian leaders as it surrounded Stalin, Lenin, and the Tsar. That organization is like a state in a state. And those people don’t hesitate to use violence. It is almost certain that the secret police killed the ex. Chairman of the KGB, Yuri Andropov. because the leader of the Communist Party, or literally the General Secretary of the Communist Party of the Soviet Union, wanted to limit the secret police’s power. The KGB probably used salt injection for that case because Andropov’s kidneys were damaged, and that caused death.

Chinese highly automated dark factories.

  Chinese highly automated dark factories. 

Chinese dark factories are so highly automated that they don’t even need light. This is the future of manufacturing. Robots working in complete darkness. Those systems are controlled by the AI. And that makes the assembly process very effective. Human-shaped robots can make almost everything that humans can. 

An advanced machine learning toolkit allows operators. To teach machines new things. very effectively. The system needs only one robot. That can make something, and then that system can scale that new skill over the entire network. That makes robots very effective workers. And maybe those ghost factories are starting to operate in Western cities. Robot factories are interesting. Especially if human-shaped robots work in that factory. 

That is the thing. That makes the AI dangerous. The ability to teach one robot and then scale that thing to all robots makes it possible to teach robot armies very effectively. The same human-shaped robot that can make cars. It can act as a robot soldier. That is one thing that we must realize. The second thing is that kinds of highly automated systems can also make other products than cars. The new stealth systems require ultimate secrecy. And the robot workers are a solution to that problem. 

The robot worker doesn’t call the newspaper. If it makes something that is not public. Another thing is that the robot worker can change its role by pressing a button. Flexible CAD/CAM (Computer-Aided Design/ Computer Aided Manufacturing) platforms that turn the CAD drawings straight to the product. Mean that the system can change the product in minutes. The factory involves 3D printers and machine workers. Those systems can make everything. They have instructions and raw materials. Those factories can make cars, aircraft, and other robots. 

That kind of thing can make many things more effectively than humans. That means those systems are the ultimate competitors for Western factories. They can make products without brakes. And that makes them ultimate operators in the military and civil sectors. The Chinese government, like all other actors, might be interested about the robot factory as a military robot producer. There is a possibility that robot factories are installed on ships. and they can build customized robots or other robot factories if they have enough raw materials. Or the ability to search for raw materials from nature. 

Russia is preparing to test a nuclear-powered cruise missile.

 Russia is preparing to test a nuclear-powered cruise missile. 

Russia is preparing the Novaja Zemlya missile test site for the nuclear-powered 9M730 "Burevestnik" (NATO codename CSS-X-9 “Skyfall”)nuclear-powered cruise missile test. The “Skyfall” missile basically uses similar technology. Which the 1950s’ Project Pluto used. But the technology that "Buresvestnik" uses is more sophisticated. Computers and AI make those systems possible. 

Today, technology is more advanced than in the 1950s. And things like reactor cooling systems are more advanced. Skyfall uses a nuclear reactor. To expand air, which gives the system virtually unlimited operational capacity. The “Skyfall” or “Burevestnik” missile’s nuclear reactor rotates an electric engine that uses blowers and compressors. Launch can happen by using a rocket booster or from a high-speed aircraft. 

The blower makes it possible that the “Buresvestnik” could use regular runways. And it will not need those rocket boosters. Is there a drone version of that missile that can return independently to the base, under development? 

https://www.globalsecurity.org/wmd/world/russia/krnd.htm

Artist's view of Bartini A-57. 

The reported range of that nuclear-powered missile is about 20,000 kilometers. The nuclear-powered ramjet engine can give the system hypersonic speed. And that system will be the deadliest tool. That has been developed after the Cold War. The “Skyfall” is the missile that can operate. With things like Fractional Orbital Bombardment systems, FOBS. The nuclear-powered missiles can also operate as so-called sub-orbital FOBS. 

These are weapon versions of  atmospheric satellites. The operational altitudes of those nuclear-powered missiles can be very low or very high altitudes. They can change their altitudes from the surface to high altitude. The power gives the missile the ability. To make an unlimited number of maneuvers. Those nuclear-powered missiles are hard targets for defense. Damage in the nuclear reactor’s shell delivers nuclear waste to the ground. Another thing is that. The “Skyfall” or “Burevestnik” can be a test platform for the new. And more advanced, and more capable systems. 

If that missile operates as it should, the road will be open to the nuclear-powered versions of the Tu-160 “Blackjack” bombers. And maybe there are plans for nuclear-powered space shuttles that can operate in the atmosphere. As well as in orbit, at least at a low Earth orbiter. Those aircraft can accelerate in Earth's atmosphere. And then jump out to space. The nuclear-powered rocket or ramjet engine can use atmospheric air that it expands by using a nuclear reactor. Then the nuclear-powered system jumps out from the atmosphere. And it starts to use the internal propellant. 

The nuclear reactor can use any propellant that it can expand with its heat. That means. The nuclear-powered aircraft or shuttle can theoretically collect and return samples. From the other planets' atmospheres. Those shuttles can also give an ultimate ASAT and strike capacity to the air force that operates them. Roberto Bartini introduced the idea of a nuclear-powered space shuttle.  Or an amphibious space shuttle. That system is based on cancelled A-57.  That nuclear-powered space plane would use water as an operating platform. The system can fill its propellant tanks with water. 

Then the shuttle rises into the air. And then. The system can use air-breathing nuclear engines in atmospheric flight. Then the system can jump outside the atmosphere. And start to use its internal propellant, which can be water. Or hydrogen and oxygen that the reactor expands. The last case requires the internal electrolytic system, but a nuclear reactor can boost the power of a regular rocket engine.

Programmable DNA can revolutionize material research.

"DNA Moiré Superlattices are the focus of a study now published in Nature Nanotechnology. Credit: University of Stuttgart / 2nd Physics Institute. In a stunning leap forward, scientists have engineered DNA to act as a molecular architect, building intricate moiré superlattices with unprecedented control." (ScitechDaily, These DNA Structures Could Rewrite the Rules of Light, Sound, and Matter)

"By programming twist angles and geometric patterns directly into DNA strands, researchers have created self-assembling nanostructures that could revolutionize everything from optics to quantum materials. These DNA-built lattices form on their own in solution, no manual stacking required, opening doors to materials that guide light, filter spin, or vibrate in precisely tuned ways — all at the nanoscale." (ScitechDaily, These DNA Structures Could Rewrite the Rules of Light, Sound, and Matter)

The DNA can make the self-assembly layers possible. DNA is the thing that can revolutionize R&D technology forever. The DNA can make it possible to create synthetic Moiré superlattices. The ability to make the nano-scale lattices and put them together makes it possible to create nanostructures like nanofibers. The nanofiber is formed from a series of lattices that are a little bit twisted. That means every layer of this structure has a slightly different angle from the last one. And that makes the structure that is the series of angles look like a solid string. 

This thing makes it possible to create structures that are self-assembly. The DNA molecules can control those Moiré superlattices and make them at the right points. That thing can revolutionize sound, light, and matter. Those layers can change their form when some kind of wave hits them. Those layers can also send counter waves to incoming waves. That can make it possible to make weaker echoes from the layer. 

And that makes DNA-controlled nanotechnology possible. The DNA-controlled nanomachine can make more complicated things than the simple nanomachine that operates based on non-organic data storage. The DNA molecule can store lots of information. That molecule can make nanorobots with complicated and versatile operations possible. The self-assembly nanostring can make it possible to create systems that can close blood vessels to the tumors. 

Another way to make nanotechnical, two-component medicines. The idea is that two nanomachines carry two molecules into the wanted cell. The self-assembly molecules can also act as the medicine themselves. The system can create a nanostring that can have a self-assembly mode. When bits of the nanostructure slip into the cell, they start to form larger structures. And then that structure can lock the ion pump open. There can be a molecule in that nanostring that makes the cell remove it through the ion pump. Basically, that means the other side of the molecule is ionic, and another is anionic. 

When that long molecule travels through the ion pump, it will start to hang on that pump. If the nanostring has the nutrient molecule on the other side, it can put the molecule back within the ion pump. Or, the molecule can be so big that it cannot pass the ion pump. But those systems require self-assembly molecules that can travel in the cell. 

When those machines are in the cell, they connect those molecules. And that activates medicines. When we think about things like intelligent bubbles that can destroy cancer cells and bacteria, the problem is simple. How to make those bubbles travel into the wanted cells. One solution can be the slime that makes the DNA travel to the cells. The bubbles that are in that slime will also slip into the cell. And then the ultrasound starts to oscillate them. The idea is that those bubbles will start to multiply. The problem is that those bubbles must vanish when the cell is dead. The answer can be the DNA coffin of whisk. The DNA coffin or harp will travel in the cell. And then that molecule starts to oscillate, making pressure waves in the cell.

The new rotational detonation engine allows the aircraft to fly 19955,87 km/h.

"“It’s Not a Missile—It’s an Engine”: China Reveals 12,400 MPH Propulsion Tech That Can Orbit the Planet in Under 2 Hours" (Rude Baguette, 

The new Chinese engine innovation allows it to fly at a speed of Mach 16. That kind of dual-mode ramjet allows the aircraft to fly at enormous speeds. This kind of technology also advances in both civil and military aviation. The engine model itself is not Chinese. But Chinese made it effective. 

The hypersonic aircraft can revolutionize cargo and passenger flight. The aircraft can travel around the world in about 2 hours. This thing makes hypersonic aircraft very capable for reconnaissance missions. These kinds of systems are effective and powerful tools for those missions. 

And that means every city and point on Earth is under a maximum 2h flight time. This is one of the biggest things about the complicated hypersonic aircraft. The hypersonic missiles are less complicated than hypersonic aircraft that must withstand temperature changes and the stress of the pressure. The hypersonic aircraft can raise rockets to orbital trajectory. 

They can climb to the ballistic jump outside the atmosphere. And then those things can release the satellite carrier rocket. The problem is that those systems are suitable for anti-satellite missions. And that makes hypersonic aircraft more revolutionary than anybody thought. The hypersonic aircraft can also carry hypersonic missiles and hypersonic gliders that they can use for attacking targets all around the world. The hypersonic aircraft can destroy other aircraft by using its sonic cone. The same way hypersonic aircraft’s sonic cones can be used to knock down conventional subsonic cruise missiles. 

“In 2023, General Electric demonstrated a ramjet with rotating detonation combustion. It is a turbine-based combined-cycle engine that incorporates a gas turbine, rotating detonation engine, ramjet, and scramjet.” (Wikipedia, Ramjet)

The key element in the Chinese new innovation is the dual-mode detonation. Or in other words, rotation detonation engine, RDE. That kind of engine system can make it possible to increase the speed and capacity of the Ramjet engine. Normal ramjets have their speed limit about Mach 7. The RDE can raise the speed of the aircraft higher than ever. The hypersonic aircraft must fly at a very high altitude, because that decreases friction. 

The hypersonic aircraft that can operate both air-breathing and internal oxygen can be the new tool for space systems. The ability to fly at high altitude. Change to the rocket engine, and jump out from atmosphere, allows the creation of a space plane that can travel even to the moon. The space plane can be the holy grail to space engineering and space stations. And other things, like nuclear rockets. Those space planes can be even more revolutionary than hypersonic aircraft. The hypersonic plane can act as the model for those more capable systems.

The intelligent pills and nanosubs are coming to the estrade.

Intelligent pills mean systems that deliver medicine only when the body needs it. The system is a microchip-controlled capsule and sensor pack that analyses things like blood sugar and then releases diabetes medicine into the body. That is one of the most conventional uses of the intelligent pills. The intelligent pills can also detect things like the neural system’s animal functions and release medicine to the blood. 

This kind of thing can help to make people survive neurotoxin exposure. The intelligent pills can release atropine into the blood if a person is under nerve gas exposure. Theoretically, all medicines can be released from intelligent capsules. But the system must recognize the threat. And then release the right medicals. 

The intelligent pills can also map the gut and find things like harmful bacteria from the stomach. The most extreme version of the intelligent pills is the nanosubmarine that can swim in the human blood vessels. And then inject the medications into the right cells. That allows the use of new types of medicals like artificial mRNA to fix the cells.  

"Nanosubmarines, or nanosubs, are synthetic microscopic devices that can navigate and perform specific tasks within the human body. Most of the self-propelled devices will be used to detect substances, decontaminate the environment, perform targeted drug delivery, conduct microsurgery and destroy malicious cells. Nanosubmarines use a variety of methods to navigate through the body; currently the preferred method uses the electrochemical properties of molecules. There have been multiple successful tests using this technology to heal mice with inflammatory bowel diseases. The general goal of nanosubmarines is to be able to produce a machine which can sense and respond autonomously, all while being fueled by its environment."  (Wikipedia, Nanosubmarine)

Above: Artist's view in nanosubmarine in veins. 

The main purpose of a nanosubmarine is to navigate the body and perform a specific task. The most speculated task is the treatment and diagnosis of diseases from within the body. This is supported by the task of detecting substances, as most diseases cause a specific type of protein or other molecule to be made in abundance within the bloodstream. Another speculated task is microsurgery. With this technology, doctors will be able to perform surgery on specific locations from within the body..One example of this could be a treatment for cancer. A nanosubmarine could be built to detect specific cancer cells within the body; after locating the cells, the nanosub would be able to kill only the mutated cells and ignore healthy cells. " (Wikipedia, Nanosubmarine)

But intelligent nanotechnical systems can also make it possible. To perform X-ray fluoroscopy. Or ultrasound research in the human body. In that case, the sensors. Those around the body can send signals that allow for mapping injuries from the body. The system can use receivers that are connected to the skin. The system can use ultrasound to make images of tissues and bones to search and report injuries. The internal systems can also observe blood pressure and oxygen level, and nutrient needs. The internal system can send acoustic or electromagnetic signals from inside the body. And that makes it a more effective way to observe tissues. The system allows real-time observation of the blood pressure, blood flow, oxygen and many other things. 

In the most radical visions, those systems are surgically implanted. That kind of system makes it possible to search injuries from the body using a system that is based on surgically implanted sensors. That system can also communicate with receivers that connect this system to BlueTooth and computers and mobile systems. That kind of tool can be effective in everyday work, military operations, and sports. People like astronauts also need a system that can search injuries in real time. The ultrasound- and X-ray systems in the suit can detect injuries and observe the health of the operator.
