a zero independent reality
What is written here, on this site, is difficult to understand in the classical sense. Meaning, there is such a thing as a pre-amble state, a current state and a post state of any given object (assuming an object is an individual thing).
In a classical way, we see the universe that contains a past, one we can view to a point of creation by "looking back" and a present state one we can view here, which follows into a state that can be predicted at some later time, a predictable location down a confined path. This is classic causality. State 1, is affected by something at state 2 which classically gives us state 3, predictably.
This site explains (sometimes ad nauseam), that there is no such thing as independence, that division and convergence is creation and they are continuously congruent (happening now). For our classical way, there is an observer (that somehow has nothing really to do with the a phenomena) and a phenomenal observation. The defining characteristics stem entirely from locality (a difference of a space). We observe classical entropy of effect as it spreads out across a space. A droplet of water into a pool of still water, spreads out in a wave that dissolves into stillness under a certain state of the entirety of the system understood by the observer. This dissemination of energy is the general, classical experience.
In our water droplet example, we witness the trajectory of causality. This is the experience of being, there is not another sort of thing happening. There is no underlying phenomena casually causing stuff to happen. But, there is, of this phenomenality, a duality where the droplet never happened to touch the still water, which we can imagine occurring that includes "other phenomena" impacting such an event, like a short breeze pushing the droplet away from the pool, to another different surface. That "other external phenomena" exists in tangent with any other phenomena, including the entropy of the wave collapse.
The Big Bang is a phenomenal way which we try to understand as a kick off of time and space. One that we, as humans experiencing causally, and happen to be lucky enough to fit into this window of opportunity to experience. Meaning, an end of time will inevitably make it utterly impossible to ever experience (the duality of a past/future). Yet, where we actually exist, eternally, is now. A moment without another, always full of causal potential, identified by the imagined and the real, experienced through separation as space. This duality pervasive across all spaces at all times, this now, imbued by a past, as a narrative to a future.
