Abstract
Theories such as causal sets and causal dynamic triangulation teach us that, the world we live in, composed by the causal sets. It is shown that, an information probability type can be attributed to born probability of the timid children in the causal set, but, due to the causal structure of the theory, the probability can be replaced by the topos truth values, and in consequence, the probability will be appeared as an emergent and non-fundamental concept. Accordingly, we introduce three generalized principles, called contextuality, equivalence, and absolute cause and probable effects. Based on the generalized contextuality principle, an eternal non-causal universe exists. The creation of observer-dependent causal (worlds) sets (called collapse of events) is the result of the interaction between the concisions observers and the universe which can be explained mathematically through introducing a pyramidal operator. Using the metric of conscious observers and the Green function of causal sets, we show how one can define the pyramidal operator. Based on this vision, time and time evolution are emergent and non-fundamental concepts. Also, the transition between the eternal universe and non-eternal worlds or between parallel worlds only occurs when the observer's consciousness changes. It can be assumed that the essence of observers (or facts) is enteral and preserved under the transition between the universe and the born worlds or between parallel born worlds, and as a result, it provided an appropriate answer to some philosophical ambiguities.
