Today is Mother Earth's Day.

Today 22.4.2023, we celebrate the day of the only known habitable planet, our home Earth. The fact is this, even if there would be billions of species in space we are only humans in the universe. Other intelligent species might look similar to us. But they also not be humans. There could be billions of habitable planets in the universe, but still today, we have no technology to reach those planets. That means we must awake to handle things like pollution and global warming. The problem is that we have the knowledge to handle those things. 

But we need the willingness to handle those problems. We know that our route will take us to doom. We have specialists who say that carbon emissions are one of the biggest reasons for that climate change. But then something is missing. Nobody even thinks about change. 

The main question what would we expect about alien encounters and artificial intelligence? The general AI is one type of alien organism. And the description for the alien is the intelligent, non-human species. So humans also can create aliens by using genetic engineering. Or humans also can create another intelligent species simply by using computer code. What would we want from that creature? 

If we ask something about the biggest problem on Earth, the AI would say that climate warming that caused by humans. The reason for that problem is the overuse of fossil fuels that release carbon into the atmosphere. And then the system might suggest a decrease in fossil fuel use. Maybe we would cut that AI off because we don't want to hear the answer. The main problem with Earth is humans. Overpopulation and other things are the worst things that we are facing.

When we are talking about things like remote work, those things would help to decrease carbon emissions. And they would keep streets open. But there are leaders, and some other people, who resist remote work because in those cases the person will not work 8 hours effectively. The main problem is that new things always cause some kind of friction. And that is one of the reasons for the resistance to those kinds of ideas. 

"Man is wolf to man." Most of the reasons why humans are dying at a young age are caused by other human actions. Or more commonly, the man's behaviors. Things like violence but more often bad lifestyle like smoking, drinking alcohol, and eating too much fat causes health problems. So the man is a wolf to himself rather than other men. Of course, there are wars on Earth where people are dying. But the most common way to die is the use of alcohol and an unhealthy lifestyle. 

When we are making things like AI that are very impressive, we don't renew systems that produce electricity. The production of the base energy is the problem. That system keeps the Western civilization rolling. And all Western systems require electricity. Without electricity, all nice computers and computer-based algorithms are a pile of sand. 

Time dilation and interstellar travel

 I will not handle cryonics, genetic engineering, or transhumanism in this text. Those things require their essays. 

Many times before researchers wrote about the possibility that interstellar astronauts will protect themselves against aging by covering their spacecraft using ion whirl that travels with the speed of light. There is one big problem with this kind of travel. 

The universe expands all the time. And that means the energy level of the universe will decrease. The time dilation by using the ion whirl or Tipler cylinder is based on the idea that the system freezes the energy level of the craft at a certain level. That means the difference between energy levels in the spacecraft and its environment increase. 

That means when the system removes the rotating whirl, energy will start to travel out from the spacecraft, into its environment with a higher speed. And that means that in this model the aging of the particles is very fast. So the problem is that the energy level of the craft must rise so high that it will not be destroyed when time dilation ends. 

So every time, when the craft removes that cylinder it must make some kind of preparation. The energy level of the craft must decrease very slowly. Or the free energy released from the material destroys it. 

"Interior view, showing alternating land and window segments" (Wikipedia/O'Neill cylinder)

The craft would use unmanned probes even if it would carry a crew before it enters the other solar systems. The preparation for that process would be very long-term. And that means the craft will not remove that cylinder or time-dilating system without a good reason. Whenever it removes that ion whirl or stops the rotation of the Tipler cylinder its material turns older.

In many visions, the futuristic interstellar spacecraft would be the combination of the O'Neill and Tipler cylinders. The O'Neill cylinder is the giant artificial world where are the plantations and other things. And Tipler cylinder is a fast-rotating shell or ion whirl that causes time dilation in the O'neill cylinder. 

The craft can have two or more shells. The shell operates AI-controlled probes. And the shells that are forming time dilation in the manned capsule.

Those things would be very large-scale projects. And that means they will be possible in the distant future. In some visions, the high-power magnetic fields or electrons that turn those electrons into miniature black holes can keep this kind of structure in one piece.

The problem is that those crews will not return. But there is one way that can make this kind of system return to home even if the journey takes thousands of years. That thing is the time machine. In that model, the energy level of the craft will rise to the level that it will start to travel back in time. So otherwise saying, inside the craft will form a black hole. That energy level should be so high that it pushes craft into the fourth dimension.

The first contact with an alien civilization is most likely the contact with the AI-driven probes.

Even if aliens would have photosynthesis in their skins, they might send AI-driven probes, before they will go to some new solar system. 

The AI-driven probes are most likely the first contact that we get with the Aliens. Futurologists created this model of the first contact. And they used our space programs as the model. In this kind of model, the machines go first. Maybe someday in the distant future, those travelers sent by humans. And they can make contact with primitive aliens. 

And they search for suitable worlds to colonize. Even if aliens use wormholes in space travel that system requires that they will open wormholes to the solar system. And if there is nothing in some solar system they will not send manned crafts. 

Even if the space travelers manned spacecraft is the giant artificial world like the O'Neill cylinder where time stopped by using a whirl of ions that is around them. Or the crew will be in hypothermic sleep that kind of traveler will send the unmanned probe before the system makes decisions about stopping the ion whirl or waking up the crew.

If there is nothing those kinds of maneuvers are risking the missions. In the models of the interstellar missions of humans, the first thing that travels to Proxima Centauri is an unmanned probe. That kind of system is controlled by highly sophisticated artificial intelligence. And maybe someday we will make that mission. 

But there is another possibility. In that case, the OI (Organoid intelligence) can control spacecraft. That kind of system is the computers. That is connected with living, cloned neurons. Theoretically, if that system has the right type of laboratories, it could create a copy of any living organism by using genetic engineering. 

It just requires the DNA sample of the targeted species. And then the system can use highly advanced nanotechnology for those kinds of missions. 

In some models, the aliens could use at least electromagnetic wormholes to shoot the aliens into the wanted planet. The system will generate an extremely high-power laser ray. And then it will send miniature spacecraft in that laser ray that denies its aging. In that craft, the alien can travel in the form of stored DNA. Or there is the possibility that the morula-level embryos stored in those spacecraft that are smaller than peas.

In that model there must be a robot base, waiting for those embryos that could travel even thousands of years. There the organoid intelligence operating robots will grow and manipulate genomes so that those first colonists can survive in that distant world. 

In those miniature spacecraft could be alien DNA and the nanotechnology that makes the craft connect that DNA to some local species. There could also be some kind of system that is transferring required data to those hybrid creatures. 

The cosmic seeds are the theory that the life or origins of life are traveling in space. If we think about alien intelligence, the seeds of life can be miniature spacecraft where is alien DNA stored in them. Then those pea-size or smaller spacecraft inject that DNA into wanted cells. And there the nanotechnology will connect the alien DNA to the right points of the wanted DNA. These kinds of theoretical systems are interesting. And maybe humans use them somewhere in the future.
