Absolute nothing is a fertile field.
If a universe Big Banged ex nihilo once, then it may have happened countless times before. Universes may still be Banging away into existence as you read this, all of them doing so in a direction you can’t point to (with all of this dependent on time having any meaning outside the context of a given universe and in the superspace that contains the hypothetical multiverse). We would perceive but one universe in a vast multiverse — and not much of that one universe, it would seem.
Current estimations hold that our universe is composed of 68.3% dark energy and 26.8 percent dark matter — substance we can neither grab nor perceive makes up most of everything, and apparently we are not a part of it. The normal matter that is accessible to our senses (and of which our senses are composed) presently makes up only 4.9% of our cosmic pie (in a potential superspace bakery).
This is not to suggest that our senses are sensitive to so much as a considerable fraction of that 4.9%, of course. We have a set amount of senses among those available in the animal kingdom, each picking up but a narrow range of a specific type of signal. This data is edited by our subliminal beliefs and values, integrated and finally translated by genetically-hardwired processes. This translation is stored in sensory memory and subsequently and involuntarily recalled by consciousness in working memory. Only then does it become our “immediate” experience.
All we know of the external world derives from what we “remember” regarding what our body experiences. As a consequence, our Here and Now is truly There and Before. Even at our most attentive we have no hope of living in the moment; we are forever riding its coattails. We are all living in the past and no one is ever right where they are standing now.
When your body’s memory of the moment passes by working memory, it might be stored in long term memory, from which consciousness in working memory might summon it through retrieval cues. When long term memory swallows something, however, it seems to in some sense digest it, break it down, dismember it — and so recall always involves creativity on the part of the recollector, as memories must be literally “re-membered.” To some degree one always incorrectly recalls past events and may even go so far as to produce “false memories,” which is to say one recalls events that never even happened in the first place.
Despite this, memory serves as the backbone for our sense of identity and our understanding of the world. Long-term memory suggests the temporal dimension, which is the only way we can make sense of the spatial dimensions suggested by sensory memory. Our reliance upon memory is inescapable. We require it to compile and associate data, scientific or otherwise. If we are honest, all that any of us ever know is memory, and all memory is ultimately false memory.
Even what we accept as imagination and fantasy is dependent upon the ingredients supplied by memory: it is no coincidence that the way in which we experience anything subjectively has analogues to our biological experience. Inner-senses are modeled after our biological senses and for all we know reveal our true consciousness as accurately and completely as our biological senses do with respect to external reality.
We try to make sense out of our external experience and so form worldviews; we try to make sense out of our internal experience and its relation to external experience and so form identity. As a consequence of our worldviews, we tend to conform our experience to them, and so further obscure our sense of reality. As a consequence of our identity, we tend to conform our internal experience in such a way that it reinforces our identifications. In so doing, we further obscure our sense of self. To make matters worse in both cases, this fatal flaw is the law and it is followed without exception: we can do no more, no less, if we have any hope to survive.
