What is a "simulation hypothesis" that the real world is just a simulation?

The world that we feel is "reality" is actually a simulation "Simulation hypotThe concept of being issued has been issued. An animation movie about what simulation hypotheses are affiliated with celebrities such as Eulon · maskIs Reality Real? The Simulation Argument"Explains it.

Is Reality Real? The Simulation Argument - YouTube


Our brain is impossible to perceive all phenomena occurring in the universe. Therefore, in order to grasp the natural phenomenon in the real world it is necessary to use "concept (concept)".


Advancement in technology will spread the view of the world and also make you realize the difficult problem that can not be resolved.


In the future where technology evolves, it may become possible to simulate the phenomenon of the entire universe.


However, is there a possibility that "it is already there?"


Is not we a creator, a creation product? In other words, "Is not the world in which we live is a world simulated by an alien with advanced civilization?" Is "Simulation hypot"is.


Even if the current understanding of physics is correct, it is impossible to simulate the myriad things in the whole universe.


As a matter of fact it is also true that there is no need to simulate the entire universe. It is enough to say that the discovered "universe" alone.


On the contrary, you do not need to understand everything about the microscopic world such as cells and bacteria. Presence that can be confirmed with a microscope may be sufficient.


There is no need to grasp the structure from the atomic level of the chair legs.


Even if the contents are empty, no problems will arise as long as there is an outline that functions as a leg.


There is no definitive methodology for simulation hypothesis, but let's examine what happens when the world is simulation.


Based on Nick Bostrom's hypothesis, it is based on five assumptions.


Assumption 1: "Consciousness can be simulated"


There is no one who knows exactly what "human consciousness" has.


Let's take a hypothesis that you can create consciousness by simulating the brain.


The structure of the brain is tremendously complicated, and the interaction between synapses is 1 垓 (10 20)) times per second.


When trying to simulate human history at the same time ... ...


For an average of 50 years per person, it is necessary to operate a tremendous number of times as one year (30 million seconds / year) × 50 years × 200 billion people × 1 time / person / second = one person.


It is this number alone with human beings, and if we include all the phenomena in the whole world, it seems impossible to create a computer that can be calculated, but it may be possible ....


Assumption 2: "Advances in technology will not stop soon"


Let's suppose that technological progress that has been continuing so far will continue in the future.


Humans may become existence which can not be distinguished from "God" some day.


It makes it difficult to realize a computer that can handle unlikely numbers ... ...


There is also a hypothesis that this can be realized.


"Matrioshka brainIs a hypothesis of a structure that consists of billions of parts on the star's orbit ... ...


In advanced civilization that Matrioshka brain realizes, the number of human beings is limited.


Furthermore, with the quantum computer, the size of the computer becomes dramatically smaller, and it may become possible to realize a huge amount of calculation in one city.


Assumption 3: "Highly evolved civilization escapes self-destruction"


If civilization evolves certainly certain times, the simulation hypothesis will not be established.


However, looking at outer space, there are countless advanced civilizations created by aliens.


By developing a barrier called "Great Filters" with advanced evolution of civilizations, we will create a world that will not be destroyed by nuclear war, meteorite collision, climate change and black hole creation.


Assumption 4: "Highly developed civilization seeks simulation"


It is difficult to imagine what happens to the evolution of human beings (Post Human), but it is a thought to think that it has the power like God.


Let's think about small ants and birds.


It is interesting that birds think "what is human?", But you will not understand the pleasure of roller coasters or the joy of eating ice cream.


The same goes for Post Human. From God, post - human beings are like ants. It is a silly idea to run a simulation from a scientific interest-oriented perspective.


However, if Post Human wishes to run the simulation for some reason, that possibility is not zero.


Hypothesis 5: "There is a possibility that human beings will live in one of them if there is a large amount of simulation"


There are different kinds of things if there are simulated civilizations.


After all, posthuman will assume that you will have the power of an endless computer.


If you simulate millions of universe, there will be billions of conscious creatures in it.


Conscious things that will live forever mean a thing simulated.


We feel that we live in the real world, but the possibility of being a simulated existence is not zero.


This fact is based on many assumptions that can not be ascertained at the present time.


Therefore, many scientists deny the simulation hypothesis itself.


Nonetheless, we live in the real world, but as we are living in the world of simulation, there is not much difference between us. What we hope is "to live better in that world"


You can survive unless someone inadvertently powers the computer running the simulation.
