The word 'omniverse' does not represent a recognized concept in mainstream physics.

If The Road to Reality (from which the term omniverse, or "omnium", originally sprung) is not "mainstream", then pray tell what is.

[E]ven if the probability for an event in our universe were 0 that would in no way serve as an impediment to its occurring in the long run.

This is a technical aspect of the discussion, and is not contradictory. The point should be clear if one considers the possibility of flipping 100 heads in a row on a fair two-sided coin. For all intents and purposes, the probability is 0, but that it may happen is not in the least prevented or negated were we to consider an infinite ("long run") flipping of coins. Pretty straightforward and not contradictory.

I can substitute this phrase with "countably infinitely many" and the structure and strength of your arguments would not be changed.

Had I devoted the energy to a full-length discussion of the topic, this probably wouldn't be an issue, but (in general) it should be clear that the number of such worlds (or universes) should be uncountably infinite, not countably infinite. That is, the cardinality would be on the order of Aleph-1, at the very least. And I seriously doubt that had any bearing on prase's original point.

This response is not constructive. Provide references. Also, you changed context from ... without clarifying what you meant by the first phrase, which I cannot parse in a way that makes sense.

I guess you could read on the topic, if you're interested. I've already suggested at least two (namely, Hawking and Penrose). Do I really have to do all the work? I need to eat and making a living.

First, your tone unnecessarily escalates the hostility in this comment thread.

There is no "tone" here. That is a mind-projection fallacy. If anyone liberated of mammalian instinct can read what I say without imputing emotional overtones thereto, then it should be obvious that my points consist in reasoned discourse without torrents of bluster at all. It's almost as if you people wish to say, "yeah, we can see you holding that 9mm, just waiting to bust a cap, and the foam dripping from your mouth". It's really rather cute.

Your last two sentences are interesting, but I'm currently short on time. Grant me that I will return to respond to them later. Thank you.
