Thanks for that. Well, we've got the name sorted at least, other stuff may take a bit longer I suspect!

It may well be he was introduced with Saul Perlmuter and I assumed he was also at Berkley

Please forgive my spelling but the name given verbally on a CMB discussion was Anthony Bagheri. It discussed bubble universe formation and suggested there was CMB imprints.of early collisions with other bubble universes shortly after the inflation phase. These appeared a circular areas on the map.

In the CMB WMap there are circular areas which according to one astrophysicists view accords with other 'bubbles' forming and splitting off. Sorry I cannot recall his name but could find it, he is at Berkley anyway.

There are some indications in the CMB map that our universe was one of 'many' that could have formed and undergone subsequent inflation. This would seem probable from a non-uniqueness point of view. So I wondered if thinking had progressed on basic issues taking this into account. Such as...

Thanks for clearing that up ' its the field that fills space..' so many even quite scientific articles have said its the Higgs bosons that fill space, and that it creates an effect like moving through treacle etc - suely its only accelaration that is affected?

Yes we know the inflation factor is much weaker than any other attraction even gravity and therefore, despite a small effect gravity holds systems more or less in Newtonian motion. What I struggle to conceptualize is how this spacial/distance inflation plays out as you move from intergalactic to...

I don't want to reinvigorate the arguments above but from a non-specialist viewpoint the question 'expanding into what' (and I really do appreciate the geometric nature of this and am comfortable with the extra space/space itself answer, I sort of prefer inflation) is the usual question, but...

I'm sorry for time wasting, must have crossed in the 'post'! I'm going through his referenced articles

I've no trouble conceptualizing the expansion but I was trying to give a more visual backcloth to my question. Which is; does the 'space' somehow 'flow' around and through the bound structure/object in the course of its expansion, or is something much more weird happening. Even the word flow...

Yes, perhaps I should have used a more 3D analogy like the rising of bread dough, where here you could imagine a cubic lattice (L1) of side say 2cm embedded within the dough ball. As the dough expands through and around, the lattice would remain at 2cm due to the connecting rods. And if you...

I need some clarification on this. I understood that the 'fabric' of space is expanding - like the 2D baloon suface etc, but in bound systems like galaxies or planets (or us!) the attractive forces easily overcome expansion. The accelration due to expansion is a very small fraction of the...

Marcus I was intrigued by the SA article dealing with models of space-time, and ending with speculation on a possible fractal/size dependent dimensionality to space-time you referenced in your reply (hopefully still above). To save me wading through lots of stuff have you any references for more...

-------------------------------------------------------------------------------- Thanks 'Billsaltlake' and 'phyzguy' for the reference below, it takes care of most of my question (for now!) 'http://www.mpa-garching.mpg.de/galform/millennium/0504097.pdf'

As I said I'm rambling ahead of the evidence with a few unfinished thought trains and need to go back to some of the research cited above to get a better grasp of the issues.
