Okay, now we're talking.

That isn't parsimony, that's ontological promiscuity of the worst sort.

alicorn&robinZ: i talked about ontological parsimony. you're talking about something else. epistemological parsimony, perhaps? same for mystery. that you can prolong it doesn't mean there's less of it.

cyan: yes, this might be a problem. you sure natural desity is the right measure?

zmdavies: looks very interesting. thanks!

jack: yes, I saw that problem too. That's why I said the theory might be self-defeating. My idea was that even if inflation as a theory is strictly speaking forbidden, it can phenomenologically point in the right direction. I mean, we might be still able to say something like: the "quasi"-observation" or the "quasi"-theory is true.

But what I said isn't the same as saying the theory is self-defeating. The theory is just based on a false premise (that inflation allows for regions of finite space that violate our recorded laws of physics). Inflation says: "Any given of configuration of a region of finite space that does not violate the laws of physics exists infinitely many times." You say: "There are some reasons of finite space where the laws of physics are violated!"

This does not follow!!!

And as I said before, the size of the ordered region, and the amount of order in our region is too great to be justified by the anthropic principle.
