Virtual Universe {\&} Its Interface to Physical Universe

This paper postulates a virtual universe and compares and contrasts its properties to that of our known physical universe. A particular attention is paid to the interface between the two and challenges for transition from one to the other. Also discussed is the relationship of the virtual universe to such entities and concepts as dark matter, black holes, time travel, speed of light, mass, gravity just to name just a few. The paper also discusses interface between us physical beings and temporary virtual beings and eventually ultra beings. It also tangentially discusses relationship between body, brain, mind of physical beings with that of virtual and ultra beings. The paper also discusses why virtual beings do not have the same limitations and capabilities as we do. The past, present, elsewhere and potential of physical and virtual universes is compared. Finally possible pathways to discovery of TOE (Theory of Everything) is hypothesized.
