Hi Karl.. those thoughts were with me before I understood that fractals even were on the table. The various propositions put simply for the Universe are all difficult to entertain. I certainly would prefer to be able to think the Universe is say (as I once thought from something I read) has an approximate size of 65 billion light years.. a humans brain can mange that even though it has absolutely no idea how big that is..infinite by any humans comprehension.. however the point comes where one can say well lets say it is 65 billion light years big, diameter and 13 .5 billion years old..at this point I find myself saying ..did we have "nothing" before and there are answers that can manage the age somewaht better than the next point..as big as it is being finite it must therefore exist in something..which we can only assess as nothing... nothing is my problem.. if you see what I mean..I can not envisage a sea of nothing it does not make sence to me.. do we get the the edge of our finite Universe where the earliest photon races before us into a void, into nothing thereby converting it to space... I draw a distinction as must be between nothing and empty space..I can accept empty space thats easy but to accept nothing that is another matter..my brain rejects the posibility.. that is all I am on about.. as hard as I find to accept that the Universe may be infinite find it just as difficult to accept we reach a fence line between space and nothing.. even if you call it empty space or nothing than ones mind, at least mine, then requires a boundary to be set for it.. and again we come up with infinite..
Going smaller is perhaps easier is some respects but wow which even one you go for it is difficult to imagine.
AND my curse is that so much of my time is bound up in this kind of thought.. its like the proverbial dog chasing its tail..or the chicken and the egg proposition...for me at least.
Even if we move to the multi Universe my mind drifts to well do they sit in a sae of nothing finally.. even string theory with trillions of Universes at their disposal if all laid end to end I still see a point where they will or will not end.
Sorry to be brief but I am expecting a visitor I dont want to get caught half way thru this..but now its complete although probably contains many an error try to read past them.
So I dont focus on one proposition or the other as either leaves a situation that a human mind can not manage I feel.
Best wishes
alex
