What's an Simulated Universe? The Simulated Universe argument suggests that the universe we live in is a complex simulation that is the actual universe. Every aspect of life, including animals as well as plants and bacteria are included in the simulation. This extends beyond Earth. It is believed that all planets asteroids, comets galaxies, stars as well as black holes and the nebula also are in the simulation. Actually, the whole Universe is a model running within a highly sophisticated computer system created by an intelligent species that lives in a cosmic parent. In this essay I present an overview on the Simulated Universe argument and explain the reasons why philosophers believe there is a strong chance that we are in the form of a simulation. I will then go over the kind of evidence will be required to determine whether we actually exist in the simulation. Then, I will discuss two points of opposition to the argument, before concluding that, while intriguing however, we must reject any Simulated Universe argument. It's a Possibility The possibility of living in a simulation of the universe an idea that is derived from the notion that there is a possibility for computers to mimic everything that functions as the computer. Computers can simulate any mechanistic system which follows the rules of a Unimuda Sorong set of pre-defined rules. Since it is true that the Universe is a rules-based system that is operating according to the finite physical law that can be understood and comprehend, it is logical that it could be recreated by computers. The advocates in the Simulated Universe argument suggest that the event it's feasible that we imagine the universe, then it's probable that we are in a simulation of the universe. Why do they believe this notion? It is because those who support the Simulated Universe argument suppose that the moment it becomes feasible to construct this kind of simulation, then we'll likely create one in the near future, provided that our human desires and preferences remain the same as they are today (Bostrom 2001: pg 9). They also argue it is likely that any animal species which develops within the simulation could develop its individual Simulated Universe. It is possible to build their own simulations since they exist and they exist within an imaginary universe. There is a possibility to keep this creation of universes for as long as you want with each universe producing intelligent species that construct the simulations of their own. In the present, with the nearly endless number of universes with children there is a greater chance that we are as a part of one of billions of different simulations than the single parent universe. This is especially evident when we think about the possibility that in these universes could exist multiple worlds with intelligent lifeforms, all of which are developing their own versions of reality. How does it all work? When you view computers running in a virtual universe, it's not necessarily an option to turn on a TV monitor or computer screen to see the universe from afar. It is not a computer that contains virtual reality-based creations of individuals living in their universe. It's not like playing games like "The Sims" or "Second Life". There aren't any graphics in the game. From the outside what you see is numbers. All you see is numbers. A complex manipulations of numbers. Like any software the numbers are created via the hardware of the computer. They are saved in permanent storage devices, like Hard-drives. Then, they are then transferred into RAM for processing by Central Processing Units (CPUs). The numbers of the simulation program are the physical laws of the universe. The numbers also represent the energy and matter in the universe. While the program runs the numbers are altered by the rules of the program, which are algorithms that represent the physical laws. The manipulation results in various numbers that remain controlled by the rules of the program. Numerous data structures made of numbers are shifted around in the memory of computers as it interacts with different data structures. As the universe that is simulated grows the structures get more complicated, but the rules which govern their operation remain unchanging and constant. Therefore, from the design perspective, the universe simulated is nothing more than complex data structures. For the creatures who reside within the simulation universe, it's all real. They sit in their windows and admire stunning sunsets. They wander around the yard and take in the scent of fresh-cut grass. They can look at the stars in their skies and think about traveling to other planets. For the people living in the simulation universe, everything is tangible and solid. Like in the actual universe it's everything is reducible into numbers, rules and. It is vital to realize that the computer isn't modeling each subatomic particle that exists that exists in our universe. In his 2001 paper, Nick Bostrom points out that it is not feasible running a model to this amount of depth. The simulation only needs to simulate local events to an extremely high degree of detail. Galaxies and distant objects are able to have compressed representations since we don't see them sufficiently well to discern each atom (Bostrom 2001: pg 4). This is an idea we could further explore. It is possible that the whole universe and local phenomena is compressed in some manner. The simulation might appear to be "interpreted" by its inhabitants as being comprised of subatomic particles and atoms however, in reality it's quite different. If we take a look at contemporary physical science, we can realize it is possible to make this a possible possibility. Think about the indeterminacy principle that is used in quantum Physics. A person cannot observe the speed and location of a particle at the same time. In addition, it appears subatomic particles do not have a precise position or velocity until the observation is taken. This is due to the fact that subatomic particles are not present in the same way that we have come to experience at the macro scale. Because we don't directly experience subatomic particles, we can say the existence of subatomic particles is a reflection of a reality to which we do not have direct access. In a simulation Universe, that reality may appear in the form of data arrays, which represent energy and matter.
