Of course my view of space/time is biased toward there not being any beginning of it because I do not believe it exists in the first place, space yes, distance between points yes, movement within a constant present yes, but not time as it affects anything of its own existance/properties.
As far as the universe being a void with other properties/energy before anything existed as it does now, I believe this does happen to large sections of the universe in what could be explained as big bangs, but that they do not include all the matter of the universe, are a local although huge event, the universe is simply to large (endless) and the matter to spead out for this to be the case, of couse this is assuming that these are the properties of the universe much as it is assumed in other theories that the big bang was all inclusive, that space is limited to the outer reaches of its explosive force, and that space/time is a product of it.
As far as something being percieved but not having mass/properties, the way I see it, these particals do have mass/properties although so small we cannot measure them, unlike nothingness, which cannot be percieved because it has no properties. I probably am not making much sense either, but in my mind it is perfectly possible.
