But can we begin to tentatively assume that the observable universe may well be part of an (dynamic) infinite structure?That (the infinite part) has pretty much been the assumption all along, and all this latest finding only shows that it is flat to more zeros than had previously been measured. Any positively curved space would imply a finite volume just like Earth's surface is positively curved and thus has finite area despite the limited extent of the visible part of it. There's no edge. You can travel indefinitely and never get to a boundary, and yet the area is finite.
So while the assumption has always been an infinite universe, they've never really been able to put sufficient nails in the finite-volume model. This is just one more nail in that coffin. The finite models don't explain anything better than the infinite models.
I don't know what you mean by dynamic. Yes, the state at a given time is different than a state at a different time, but the 'state' isn't the structure, the latter being the whole of spacetime with time as part of the structure, so the structure itself isn't something that changes, and is thus questionably describable as 'dynamic'.
A bit like Einstein and the invariance of the speed of light.He was careful never to posit that. The premise is the invariance of any local measurement of the speed of light. The latter statement is an empirical one, and the former is not, and he never committed to the metaphysical assertion in his theories.
