There is a possibility that our physical reality is virtual in the sense that it was created already in the form of a simulation or it is a manifestation of an interaction with another level of reality or mechanism. If this is the case, then there may be only a limited material horizon and any extensions of it are created on demand.
If we are living in a computer simulation, as Nick Bostrom has argued is a possibility, maybe this is not just an ancestor simulation but an interactive computer game. In this game, some of its creators, or participants, assume various roles, such as country leaders or scientists who make remarkable discoveries, and some even cause conflict and wars. Maybe the main objective is entertainment or it may be something else we do not understand and in this context some fundamental questions arise.
