With the continuous development of the brain interface technology，Virtual reality areas may usher in another major change。The brain machine interface can be read preliminary、Analysis、Output the signal and idea of ​​the human brain，In the future, you may gradually enter information to the brain、Knowledge and even emotion、Memory, etc.。Input technology of the brain interface，Can be lower at a lower cost、The effect is more realistic、A more immersion feeling，Let people enter the virtual environment or "shuttle" virtual reality。Existing philosophical reflection on brain interface，Multi -hearted relationship、Discussion on free will and ethical specifications。But，In recent years, the practice of digital social exchanges in human beings has become increasingly "reality" to "virtual" trend，We haven't made it clear what the goal of this development is，and what can we pursue。This article thinks，Metaphysics of Science with the help of scientific metaphysics，Examine the borders of the virtual world in the background of the brain interface，It is an inspiring job worthy of development。

Science metaphysics is a cross -area involving metaphysics and scientific philosophy，It responds to the problem of the advancement of the cutting -edge progress and basic research in science and the problem of going to school，At the same time, I also borrowed the foundation of the question and the ideological resources of the question and the ideological resources of the science。As one of the core parts of scientific philosophy，Scientific metaphysics depends on the overall grasp and detailed investigation of scientific research results。Compared to traditional metaphysics，Its argument is not limited to daily or historical experience and abstract speculation; compared to branch science philosophy，The specific object of its attention (such as basic particles、Gravity、Gene、mental state, etc.) More bottom and abstraction。The topic of scientific metaphysics includes natural categories、Natural Law、Cause and effect、tendency、Anti -facts、Restore and acting、Entrying、Realism and Anti -Realism、Heart relationship、The most basic concept or nature of time and space。

Bet365 lotto review Following the upsurge of the birth of the second half of the 20th century，Virtual reality today、Artificial Intelligence、Blockchain、Brain -machine interfaces and other technologies have a situation of integration and penetration，Related topics have received close attention from philosophers。This technology trend may bring fundamental changes to human survival status，Many of the situations that have not been considered or unimaginable will open a new problem domain for all directions of philosophy。especially，If we analyze the virtual world construction in the background of the brain interface from the perspective of science and school,，Many of the unsteady levels contained in it may be revealed。

　　"Fake True" and "Extraordinary"

Vision of the effect of "virtual reality" effect on virtual reality，Generally presents two trends。One is the difference between users or players as much as possible in the virtual world and experience in the real world，can be called "fake truth" type。The other is to allow users to experience the surreal (Surreal) experience that is very different from the real world，Including physical、Physiology、Psychological and other feelings、external environmental status, etc.，It can be called "extraordinary" type。Of course，In specific design，Both do not reprimand，This division is just to highlight the differences of two ideas。For the former，Although the current virtual reality wearable equipment can be experienced in the visual experience、Hearing experience and partial touch、The olfactory experience is constantly approaching the truth，But there is a distance from the fake chaos。To be a fine smell、Snow and touch experience and other experiences are as realistic as possible，Existing sensing technology、Platform computing power and data transmission capacity are far from enough。If you preset neuromatism position，It is believed that the human spirit and conscious activity can be completely attributed to the change of brain physics，Then you can consider using the input brain interface technology to "irrigate" the brain from the outside directly from the outside，instead of applying stimuli for users' sensory organs。This may make the overall cost lower，Impression and real sense is stronger。And "extraordinary" type，Existing technical conditions are more difficult to meet their requirements，The design of only in principle bet365 Play online games is facing difficult difficulties，Therefore, the development and application of brain interface technology cannot be separated。

Existing relevant cases，Most of them make players or users enter a set of established virtual scenarios for a long time，Feel "Time and Space Cross"，Perform game operations such as item control。These scenes rely on the designer's pre -set，User's experience、Operation and interactive behavior controlled throughout the process，All "accidents" and "thrilling" are just illustrations，The physical changes produced are also limited to the scope of safety。

If you want to obtain an extraordinary experience with less restrictions and greater freedom，First of all, it should be clear: What should I "surpass"? What is "separated"?。Take a simple example: Can users experience weightlessness in the virtual world? On the surface of the earth，Obviously it is impossible to "block" the geland of the earth by wearing equipment。Even relying on the highly developed brain -machine interface technology to "instill" a sense of weight or other surreal experience，We must also know: under those state，What reaction of its brain neuron tissue "corresponding"，Otherwise, what can you enter the user's mind、Is it possible to confirm whether it is lost or other desired feelings?，It is difficult to predict whether the user’s physiological and mental level is in the hidden health hazard。

In the process of trying to build a virtual world，The brain machine interface has irreplaceable importance。From the perspective of the status quo，Although the development of this technology has achieved a lot of breakthroughs，But I am reading accurately、Output brain information，or effectively enter information to the brain，Can't be satisfactory。In terms of input signal，"Cranial Magnetic Stimulation" or "Cranial DC Stimulation" can adjust the excitement or suppression of specific brain areas by applying electromagnetic field directly，But at present, you can only implant some simple visual images in the human brain。When people actually face various complex situations，A complicated reaction and experience that many scientists have not understood in depth。Effective input and output of these complex signals，All will be a huge challenge to the brain interface technology。Simulation or regulating the specific changes of a single neuron cell，Follow the complex combination and dynamic coordination of tens of billions of brain neurons，It is a completely different bet365 best casino games level of operation。As a result，Although the information processing ability of human sensory information is limited，But the human perception ability itself is constantly developing，As long as people's understanding of things in the world is constantly expanding，So it is difficult to assert that the changes in micro or macro between the virtual world and the real world in principle beyond the recognition ability。This is a problem that is difficult to achieve in the "brain in the cylinder" that is "fake and true".。

　The essence of natural law

Some optimistic ideas think，In fact, it is not necessary to be confirmed to pursue virtual and reality，We may wish to try the free construction of the real world: the constraints of natural laws such as physical laws in reality can be broken，Let the user's consciousness perceive "the sky entering the earth or turning over the sea" in the virtual world。but，If you want to realize this imagination，The first thing to ask is: whether a person can or what level can control the law of the virtual world，Make it not "crash"、Logic collapse、flaws? Can the virtual world freely violate all natural laws that belong to the real world?，Can designers and builders "legislative" arbitrarily "legislation"? This derived from a typical scientific metaphysical problem: Will natural laws change?，But in fact, it is inseparable from philosophical analysis and clarification: What is natural law? Is there really a "law" itself?，It is still an objective to the subject of the cognitive subject、Is it necessary?

Like many basic concepts of school and school，People also have a lot of controversy about the law of nature。Some people think，Natural laws in science cannot be decomposed again、The original concept of restored; some people think，There is no concept of causality if there is a natural law; some people think，No natural law exists，should be symmetrical、Mechanism、Model, etc. to replace its role in natural sciences。Scientists pay attention to the classification and change of nature things，and use various rules and mechanisms summarized to explain various changes。From the perspective of the scientific philosophy of different positions，The objectivity of this law or mechanism is not self -explanatory。In view of the many huge changes in the history of science，In many fields of disciplines, it was once regarded as a deserved ontology commitment that it has encountered major changes，Therefore, although people Bet365 lotto review summarize in scientific exploration and engineering practice and repeatedly use various laws，It is not the same as the nature of nature.，and must follow them changes、Development。From the perspective of anti -realists，Natural law is just a summary of the rules in the experience phenomena，or some practical and effective interpretation system。People will inevitably have many blind spots and misunderstandings in the real world，The currently recognized scientific theory may even be modified or subverted possibilities。

Taking physics as an example，A profound contradiction between physicists face the general theory of relativity and quantum mechanics，Try to construct many theoretical models to resolve，I hope to integrate the two。Current，A variety of gravitational theories that try to surpass the general theory of relativity are designed，Each model of each theory is used to describe various possible universe under specific conditions。Although detailed analysis can exclude many error settings，but enough complete、The theoretical solution that can withstand the test has not yet been found。For quantum mechanics，The long -term dispute of interpretation of the problem indicates that the definition of the ontology and the law is quite confused，Each interpretation of the preset real picture is very different，If you want to achieve coordination with the theory of gravity，The results brought by different interpretations and modifications will show different differences at Planck standard。So many ideas，In basic physical assumptions、Mathematics characteristics、Experimental predictions, there are more or less differences，Therefore, in the case of insufficient evidence，It is not easy to predict who would win。In addition to high -energy physics full of conjecture and confusion，Material Science、Biology、Medicine、Geology、Information science and other fields all have hanging and unreasonable、The problem of impact on the foundation of the subject。People have achieved unprecedented achievements in modern natural sciences，But in the face of more difficult difficulties，Many existing attempts are still unknown。This situation may have indicated the arrival of the new scientific revolution in a sense。

　"Natural Law" in the virtual world

Human's existing cognition of natural laws，Foreign accuracy、Self -Trust、Unified ideal state，There are a lot of unknown laws to be recognized。People Bet365 lotto review can't know what they have not realized their existence。If the human brain cognition can reach a considerable degree，and the current cognitive ability is very far from the upper limit，So，Material phenomenon under the "natural law" under the "natural law" of users in the virtual world in the virtual world，Or it can cause users' corresponding feedback、Recognition。If the virtual world is set, it is very fine、The change of the complex "natural law"，So although it may produce changes that cannot be distinguished by the limits of human sensory ability，But it is likely to cause some changes within the scope of human resolution，Otherwise, the meaning of these settings will be lost -this is exactly the user can compare with the real world、Make a distinction、Place of judgment。For example，If professional natural scientists enter the set virtual environment to experience and explore，They will recognize the problems and flaws in it faster。If you want to make the "natural law" change，reaches the effect of "natural realism"，The builder/controller does not operate directly from the physical level (such as shielding gravity, etc.)，Enter the corresponding signal for the user’s brain neurons tissue，It must also achieve the "natural law" and the user's physical、Physiology、Coordination between the corresponding changes in psychological reactions，Therefore, you need to consider the coordination and stability of all the "natural laws" of the new model。

From this see，Cognition of the laws of real and natural is quite shallow，It is impossible for us to create enough realistic、The trusted world of "fake truth"，It is even impossible to create a reasonable "extraordinary" virtual world。The construction of the virtual world cannot be achieved overnight。At the current stage，We can only be like the overhead map presented by video games，Let the user get local in the surreal situation、Limited、Unreal experience。In fact，Many existing interactive virtual applications，Not only is it not to create a whole set of "natural laws" in advance to dominate the operation of the virtual world，Instead, it is just hand -designed in advance、Arrange each possible scene。This makes different scenes have different "natural laws"，Different virtual objects and action bodies also follow different physical rules。other，Disclosure of the physical law of the virtual world and the physical law of real time space，It is easy Bet365 lotto review to cause players or users to make an accidental operation of "unsatisfactory" and make the virtual object "burst"，It may even cause logic collapse in the entire system。

No matter how virtual reality technology is closely combined with technologies such as brain machine interfaces in the future, it has made rapid progress，No matter what the appearance of the virtual world construct of "falsehood" or "extraordinary" style，This is destined to be a comprehensive technology arena and a test field for human social structure。Technical Engineering Experts and Philosophers The interrogation of the boundary between the brain interface and the virtual world of the brain machine，Perhaps it also helps to clarify the outline of the real world where humans are located。This article is selected to analyze from the perspective of natural law，It's just one of the many problems of scientific metaphysics，This article is selected to analyze from the perspective of natural law，to grasp it for people、Development virtual world brings more revelation。
