In my story, I have a machine that you can connect to using electrodes. It allows one to enter a small virtual reality room where everything from gravity and electromagnetism, down to the atoms and quarks of each molecule - everything is simulated. This means that people can practice fighting exactly as though one were in real-life, but without possibility of death or injury.
What technology is needed to create a "perfect" simulation of the world in a small space?
Specifically, what kind of computational ability would such a device need in order to achieve this?
For this question, small space can be defined as a room about 10 x 20 sq meters and about 3 meters in height.
The simulation must be able to:
- Have objects such as apples, weapons, etc.
- Everything must be simulated in such a way that what happens in the virtual reality would happen in real-life if repeated or replicated.
- It must replicate the user's superpowers - even if the user doesn't know everything about how they work
Assume that in my story, scientists have discovered the theory of everything and that it closely resembles everything we know about in the real world. (ie approach this question as if one were to simulate everything already known or theorized about our current universe)
For this story element, I'm considering having a person with a unique superpower that can touch a machine or device to make it increase its performance by hundreds or even thousands of times. Would this help explain an immense computational capability?
EDIT Clarification: Not imposing limits on this machine/technology is precisely the point of the question. The machine in my story is used to help people practice and understand their superpowers. Since superpowers vary dramatically, it needs to be as precise as possible to ensure the power will work the same way inside and outside of the machine. Otherwise, someone that can turn hydrogen atoms into gold atoms in the machine might actually turn hydrogen atoms into boron atoms in real life.
