Simulating Reality

Simulated reality is the skeptical hypothesis that reality could be simulated—perhaps by computer simulation—to a degree indistinguishable from "true" reality. It could contain conscious minds which may or may not be fully aware that they are living inside a simulation.

This is quite different from the current, technologically achievable concept of virtual reality. Virtual reality is easily distinguished from the experience of actuality; participants are never in doubt about the nature of what they experience. Simulated reality, by contrast, would be hard or impossible to separate from "true" reality.

There has been much debate over this topic, ranging from philosophical discourse to practical applications in computing.

In a virtual-people simulation, every inhabitant is a native of the simulated world. They do not have a "real" body in the external reality of the physical world. Instead, each is a fully simulated entity, possessing an appropriate level of consciousness that is implemented using the simulation's own logic (i.e. using its own physics). As such, they could be downloaded from one simulation to another, or even archived and resurrected at a later time. It is also possible that a simulated entity could be moved out of the simulation entirely by means of mind transfer into a synthetic body.

Simulators (Fill in the gaps)

Do the names Sim City. The Sims, MS Flight Simulator mean anything to you? Well, they are all popular video games that simulate reality. In Sim City, for example, players have to build 1)........... city that looks and functions1 much like a real one. with houses, shops
and factories.

However, we 2)........... only use computer simulations for fun. 3)...........are many things that we cannot study or test in real life because it would be too difficult or dangerous. Computer simulations make such study and testing possible. In the past, for example, pilot training used to be very dangerous. Nowadays, pilots can practise their skills before they enter the cockpit 4)........... using flight simulators. Engineers 5)...........use computer simulations to design and test new products before people start using them. They can identify2 dangerous faults in cars and buildings, for instance, and therefore save lives.

With the help of computer simulations we can develop new things without putting people's lives at risk during real life testing. They not only provide us with entertainment, but also play an important role in our future.
