The metaverse is an ultimate tool for many things.

The metaverse is the next generation of the Internet. We can call that thing "Internet 5.0". The metaverse is like a platform where people can operate using virtual reality or regular screens. In the SciFi novel "Neuromancer" from 1984 author William Gibson predicted the metaverse. And in the most interesting visions, the neuro implanted microchips like Neuralinks allow people to click themselves to the metaverse by using the neuro implant that can communicate with cell phones or WLAN. 

There is also the possibility that the nanotechnological system called "Intelligent dust" makes it possible that the person must only put those extremely small microsensors on the head. 

The term: intelligent dust means an extremely small microchip-sensor combination that seems like dust.  And then those microchips can communicate straight with the cerebral cortex. Or they can communicate with extremely small flexible machines that swim in neural channels.

R&D staff can put those very small microchips in the tattoo colors where they can operate without disturbing the user. The metaverse could be like some kind of house or even a virtual city. When a person looks for something the user must just go to the right house. And find the right room. In that model, all information on the Internet is stored in databases, and the user sees entrances to those databases as houses. 

Each of those virtual houses involves sorted information. And those virtual houses are like main topics. There are words astronomy, AI, and all other search words. And then the user must just ask something. The AI-based search engine can transport the person to the right house and the right house. 

In some versions, the user interface acts like the library. When a person takes some book-looking object in their hand the system asks if the wanted information in that book. And then the virtual system transports the person to the right virtual house. 

But there is possible that users can walk in that virtual world. That hiking and hanging on virtual streets could be the next-generation version of the random search. The idea for that interface is "stolen" from "Second Life" and many computer games. The idea is that if the person searches for information about things like quasars the system transports the person to the room where is all data about quasars. Or miniature robots that operate in the human body can send their information to those virtual rooms. 

Each room in those virtual houses might have a certain purpose. There could be rooms, where operators can have access to robots that make anything that their masters want. The thing is that the human-looking robot can make many things. The new skill requires that the robot's memory is stored in a new database. Or the remote controller of the robot will change. 

The miniature robots can manipulate neurons. And that makes a new accuracy for the BCI (Brain computer interface).

The MEVs (micro-endovascular probes) are systems. That can make Neuralink implants old-fashioned.

The MEV probes are ultra-flexible miniature systems that can swim in neural channels. The MEV probes are easy to install; only one injection is needed. And those probes can observe how neurons are operating. The MEVs can make chains in the neural channel, and they can communicate with cell phones through the skin. Those systems can also cooperate with neuro-implanted microchips. Neuro-implanted microchips can communicate with microchips that can be installed in hats or helmets. The EEG sensors don't require any surgical operations, but those sensor- or interactive systems that can make two-way communication between neurons and computers can be surgically installed on the skull below the skin.

If we think that a neuro-implanted microchip is the sensor that is under the skin, on the skull, installing this type of electrode is not very difficult. The MEVs can replace the electrodes that are surgically installed in the brain. And in that system, the MEVs can form the chains that can conduct the electric signals from implanted microchips precisely to certain brain lobes. The difference between those nanotechnical structures and normal electrodes is that medical staff can inject those miniature robots into the neural channel. And that makes their installation easier. The MEVs can also give an electric shock precisely at the right point in the neural structure. Those systems can manipulate the activity of neurons. And that thing makes it possible to manipulate the Brain's perception of time.

"Champalimaud Research’s Learning Lab has provided significant evidence of how the brain’s internal clockwork guides behavior. Their study manipulated neural activity patterns in rats, warping their perception of time duration. This research not only challenges conventional understanding of time measurement but also has potential therapeutic implications for diseases like Parkinson’s and Huntington’s, and for robotics and learning algorithms." (ScitechDaily.com/Scientists Discover a Way To Manipulate the Brain’s Perception of Time)

First-time researchers manipulated the brain's perception of time.

The activity of neurons determines how we perceive time. The thing that determines how we observe time is how often our brain, or our brain's visual center, saves data to memory. This is the reason why routes that we haven't used before feel longer than routes that we already know. On well-known routes, our brain must not come into contact with memory cells as often as on new routes. So if the brain saves information often, that makes time move slower.

The reason why the brain can adjust how many images in a unit of time, it emits into consciousness is that. It makes the work of these neurons lighter.

Consciousness is in the cerebral cortex. And humans also require that brain area for thinking. Because the brain must not let all information reach consciousness, it makes its work lighter. That thing also releases the cells of the cerebral cortex for some other work. In this text, consciousness is handled along with memory. Consciousness is the thing that plays a big role in memory. But even if the information doesn't reach consciousness, the brain will not store it in memory cells.

And the reason for that is that when the brain often saves something in memory, it handles many more images than in cases where it doesn't save things. So if researchers can manipulate this process, they can create a situation where a person's brain will start to store more images than normal. If the brain stores many images in certain time units, it creates a situation where our eyesight acts like a camera that laboratories use for observing very fast reactions. That kind of ability can make the work of surgeons and military operators safer. And that process can be used as a model for AI-based robots.

The shape of the brain means more than neuro connectivity.

Well, we might say that the brain is in its entirety. Another thing is that all things in the brain have some kind of purpose. The shape of the brain and, especially, the folding of the brain shell are extremely important things. Those folds are expanding the brain's surface areas. And the brain shell has a primary role in the thinking process. The surface area of the brain determines how large the cerebral cortex is. And in a large cerebral cortex, there are a large number of neurons. But as I just wrote, the brain is in its entirety.

"Researchers have discovered that the shape of a person’s brain significantly impacts thought, feeling, and behavior, overturning the prevailing emphasis on complex neuronal connectivity. Utilizing MRI scans and the principle of eigenmodes, they found that brain function is closely linked to its geometric properties, much like how the shape of a musical instrument determines its sound, offering new avenues for exploring brain function and disease". (ScitechDaily.com/Century-Old Paradigm Overturned – Brain Shape Matters More Than Neural Connectivity)

The main things that affect the brain's ability to solve problems are:

1) Folding of the brain

2) Number of neurons

3) Number of neural connections

4) The information that the brain can get from outside

There could be some yet unknown things that affect the brain's ability to process information. As an example, we know that neurons interact with macrophages. Some parts of that interaction are connected to immune reactions. But there might be other purposes for that interaction.

We know that some phobias, like the fear of spiders and snakes, are programmed into our DNA. That leads to the idea that the macrophages can also save the memory blocks of the memory cells. The thing that supports this theorem is that the brain's electric activity increases just before death. 

And after death, a second, very strong EEG storm travels through the brain. The thing is sometimes compared with a micro support person who takes data to Storage. When death comes, the "system operator" saves the memories. And then, after excites, the system checks that all databases are removed correctly.

Thinking is a term that refers to the brain's data-handling process. That process means having the ability to connect memories with fresh observations. If there is no data in memory blocks, there is nothing that the brain can modify. The outside data source is the thing that brings information to the brain. And without that source, the brain has no information. Every skill a human has depends on information stored in the brain. Without information, there is no skill.

The sensory-motor brain shells are only one part of the brain. A thinking process is an event where information travels vertically and horizontally through the brain. When the brain begins the thinking process, it starts signal processing at many points at the same time. That thing makes the brain extremely effective. And quantum computers are using the same method in their operations. 

The reason why the human brain seems slow is that our brain can retake control of the data-handling process. That means humans are harder to entice and trap than bugs. In a bug's brain, nervous signals travel in one direction. And if a bug smells something that feels like food, it acts like a missile. That smell will attract bugs to the food or traps. The human brain analyzes situations all the time. And that's why humans are harder to cheat.

Could Saturn's icy moon Enceladus host life?

 Could Saturn's icy moon Enceladus host life? Researchers found phosphorus in icy geyser eruptions. And that means there is a change. That there are lifeforms in the oceans of that icy moon. 

The conditions on that icy moon are different from Earth. Temperature is lower, but water is liquid. And that means the living organisms can look similar to Earth. But they are far away. From the organisms that we see on our home planet. One of the reasons why we might not see other lifeforms is that their metabolism is so slow, that we cannot see those products. 

The major mistake in discussions about things like hypothetical silicon-based lifeforms is that people always say that lifeform is "made" of pure silicon. Even humans are not "made" pure carbon. All known lifeforms forming of complicated chemical compounds. So there are also many other elements than just carbon in our body. And that means the oversimplified model of life is this: Life requires only liquid water, ammonia, and some other chemical compounds.

The ice grains are generated from the global ocean under the ice layer that is a few kilometers thick. Credit: NASA/JPL-Caltech/SSI/Kevin M. Gill" (ScitechDaily.com/Saturn’s Icy Moon Enceladus: Study Proves Existence of Key Element for Life in the Outer Solar System)

In some hypothetical evolutionary environmental models, ammonia can act in a similar role to water in the chemical processes of life. Ammonia is liquid on a lower temperature scale. And that means there is the possibility that some primitive, but why not advanced aliens could base that thing on. Could aliens with ammonia-based metabolism turn intelligent? 

That's a good question. Intelligence is not the same thing as culture and technically advanced civilization. The main problem with aliens that metabolism base is in ammonia is that the temperature on those planets must be far lower than on Earth. So that causes problems to make fire. And also ammonia-based aliens are far more vulnerable to changes in temperature than organisms that metabolism base is in water. 

Things like hypothetical silicon-based aliens might look like sand bites controlled by DNA or RNA. But the problem to model those extremely rare or extraordinary lifeforms is that we always make one mistake. We think that those organisms are "made" of pure silicon. We should think that those lifeforms are formed of chemical compounds that involve more than one element. 

Even if those silicone-based aliens can move, they might also be far slower than carbon-based aliens. Otherwise, we might not always remember that even humans are not "made" of pure carbon. The silicon-based chemical compounds like silicone used in building sites are soft, and that means they could be fast.  But otherwise, things like trees are not moving at all. 

So those lifeforms can be in static positions. And they might exhange genetic material by growing fibers. The hypothetical silicone-based lifeforms are different from what we are. So even if evolution chooses the "carbon road" on Earth. There is the possibility that in some other place, evolution chooses another track.

Is math real or not? Or are virtual things real or not?

Mathematics plays a vital role in many everyday actions. Things like Pi and trigonometry are in a vital role in geometry used to measure things like houses. And mathematics is used to create quantum decimal numbers. That is used in modern data encryption. 

People sometimes say that mathematics is a virtual thing. So that means math is not real. Another thing is that the world is full of things that are not real or that we must not follow. But leaving those things unattended causes serious situations. Same way as in math. We can say that things like lawbooks are virtual things. Laws are "only" written texts. But breaking them can cause serious consequences. 

Things like traffic lights base are that people follow those orders like red lights "voluntarily". And there are strict rules about what people must do when they see red light. Of course, people can continue driving when they see that stop sign. But if the police see that thing, it causes punishment. And another thing is that driving against red light causes accidents. The question is is the law real or not? 

There is no natural force that makes people follow the laws. But then we must realize that following the law is always better, than following some instincts. Humans made lawbooks. That means the law is a virtual and artificial thing that people must follow. The law itself affects nothing, but authorities that enforce the law are a thing that affects people. 

Sometimes people have discussions about topics like this. Is mathematics a real thing or not? Mathematics follows certain rules. And all mathematical formulas must be solved by following certain rules. We know that 1+1=2. But we also can write on paper that 1+1=300, but that is not right. 

The reason for that is we didn't follow the rules of mathematics. Sometimes computers make mistakes because one of their gates has some kind of overvoltage. And they calculate that 1+1=3. That was the case when people realized how important error detection is. But then we must ask another question from ourselves. That question goes like this. Should we handle everything that affects us as the real thing? 

Math plays a vital role in modern mass encryption.

Mathematical formulas like Riemann's conjecture and Shor's algorithms are not topics in so-called everyday discussions. But those things are playing a vital role in data security. And they are the most used algorithms in everyday cryptology. Without those algorithms, we don't have things like GSM-network. The encryption in messages makes it possible that the devices can filter away information that doesn't mean to it.

 So the encryption allows the device to select only data packages that are for it. And that increases the operational range of things like encoded radio-control devices and allows to use of multiple systems in the same frequency. Also, the same algorithms protect things like online payments. But as I wrote earlier. Encryption is much more than only protecting some messages from outsiders. 

A digital twin of the computer program or otherways saying backup of source code can use to detect attempts to inject non-wanted code into the user interface. 

Active data security means that the system makes a backup using the confirmed code. Then the system protects the digital twin. Then the system compiles that "digital twin" with the application's source code that operates in the user interface. If there are changes between those codes that means the program is corrupted. Or somebody tries to inject non-wanted or non-authorized code into the system. 

But then we must ask, are virtual things real?

We can ask, are things that affect us real? Things like computer programs are quite similar thing as mathematics. Computer programs are only text on computer screens. But those things interact with other things. And without those codes the computers are useless. We can say that all computer programs are similar to machines. 

They don't do anything else than things that are encoded in them. So the computer program is like some kind of steam machine. It makes only things that programmers authorize it to make. All errors and damages that computer programs make. Are made by humans. 

The term digital twin means the virtual model of physical things. Those digital twins are used in some kinds of simulations. But then we can think of the case that the computer program makes a backup copy of itself. Could we say that the backup copy is also a digital twin? That backup is the twin of the virtual thing. The system can use that "twin" to observe code. And if the system compiles those codes with each other it can see does somebody try to change the code or slip malware in the system.
