Big Bang or Big Splat?

In contrast, the spatial extent of the Universe could be infinite. If
so, it always has been infinite.

Another question, if I may. If the extent is infinite does
that imply that there are guaranteed to be other regions (an
inifinite number possibly) the size of our visible universe
that have the identical quantum state? I seem to remember a
Scientific American article that asserted this.

Further, does such a universe guarantee regions the size of
our visible universe which exhaust the possible quantum
states of such a region. You know where I'm going, I'm
sure. If this is true then the ultimate anthropic principle
seems to be that we are here seeing what we see simply
because it is possible. The only mystery that would be left
relative to our existence is the infinitude itself that
provides for it.

Further yet, can symmetries be broken differently in
different regions and if so does that say that all possible
tunings, including the fine one we find ourselves in, must
exist somewhere, somewhen?


Thanks,
