How objects exist?
There are the following interpretations and explanations of existence: • An object exist if its reference has been created by its space • An object exists if it is used or is visible by other objects In fact these two definitions are equivalent if we suppose that creation of an object reference means that it is stored somewhere, for example, by the space where it exists. That is, it is the space that always knows where its objects are or if the space forgets about its object then it does not exist anymore. Thus the object existence is equivalent to its reference existence somewhere in the space. In other words, if somebody remembers an object then it exists. Since objects take different forms and are normally distributed in space (and time as a part of space) it is always difficult to precisely specify what an object is and if it really exists. For example, storing photographs of died people makes them actually alive.
