yor_on, all physicists are constantly looking for a best "paradigm" of things (especially for what they like less, of course) but to do so, we first have to understand well "where we are" or we can't get anywhere. Don't you agree?

[yor_on (OP)]

Of course, you are correct. We all need a ground from where to build. Still there I am, wanting to know it all instantly. It's just that I really would like to understand what differs vacuum, photons, particles, 'dead matter' , life. It's like a chain, but then again, that may just be me seeing a 'causality chain'. In fact we build our definitions on expecting just that.

It's like Occam's razor, we learn how to interpret this world from the moment we are born and one of the things we take for given is that there always will be a causality chain, because that is how we experience time. The glass fall, and therefore breaks into pieces:) but that's mostly what I see as archetypes, they don't guarantee anything about spacetime, but it's still the clearest definitions we have of what spacetime is.
A beer to much here?
