The Cheering Principle for Virtual Reality Generators Rendering Each Other
For physical computers stimulating each other, it is possible to build a universal computer. It follows that if a universal image generator were toll by a universal computer, the resulting machine would be a universal virtual reality generator. This leads to a stronger version of the curing principle, the chuering principle. The set of all behaviours and responses of one object exactly mirrors the set of all behaviors and responses of all other physically possible objects and processes. So this is the basis of quantum computation. If you have a theory of physics, then you can program it in,. you can model te rest of physical reality.
