If there would be only a single electrically charged particle in the entire universe so it cannot express its charge in interactions, then it cannot be charged itself, so charge –or any property, for that matter– is something which lives within particle interactions, something a particle cannot privately own. If in a universe which creates itself out of nothing, without any outside intervention, particles, particle properties must be as much the cause as the effect of their interactions, then their communication must be instantaneous. This only is possible if the constant of nature called ‘the speed of light’ doesn’t refer to a velocity but to a property of spacetime: if we don’t live in a universe where it is the same time, where time passes at the same pace everywhere (in empty space, far from masses), which lives in a time continuum not of its own making –where there is a universal ‘now,’ but in a universe which, as it only exists as seen from within, creates all time inside of it so time must be observed to pass at a slower pace at larger distances. In such universe the communication between particles –and hence the transmission of light– is instant: not over any space distance but over any spacetime distance. Like a particle cannot be charged itself if there is no other charge; if by definition there is nothing outside the universe, nothing relative to which it can be said to exist, nothing to interact with to express its existence, relative to which its properties and state can be specified, quantified, then a self-creating universe cannot have particular properties nor be in some particular state as a whole as ‘seen’ from without nor as seen from within. As it only exists as seen from within, as it creates all time inside of it so time cannot be observed to pass at the same pace at all distances, past, present and future are relative, observer dependent notions. This study investigates how the universe might create itself out of nothing, without any outside intervention.
