Well, what "that" were you referring to when you said "And my thinking was such a state cannot exist in that it would violate the concept of entropy"? That's the same "that" I am talking about.

Anyway, while there's an interesting philosophical question of what maximum entropy is, in it's physical form, there's no actual hard facts pointing to maximum entropy spontaneously giving birth to a universe, order.

Our universe being but a pocket in a metaverse is an interesting thought, but it's more of a mathemathical play. If you care, there's an even more interesting theory of our universe being a low-energy pocket of a-forever-expanding-high-vacuum-energy-inflating-metaverse. As far as the math goes, it makes somewhat more sense than assuming the universe being a pocket in a maximum-entryopy-metaverse, but it's still about as real as tachyons (which also work out mathemathically, but have pretty much 0 resemblence to reality).

To wind back quite a lot, it's interesting to regard maximum entropy as being identical to maximum order. How comes? Order got to do with symmetry. You can have, let's say, translational symmetry, rotational symmetry, mirroring symmetry. The more rotational axes or translational vectors you have, the more order generally is there. But a state of maximum entropy has all the symmetries there are, the set of translational vectors is infinite, same as rotational axes and angles.

That's not very substantial though. For starters, talking about entropy in terms of order or chaos doesn't really hold. In physics, entropy goes woth the number of microscopic scales corresponding to the same macroscopic state, or rather to the same macroscopic energy.

Back to the big bang, the universe being an island in a vast world of maximum entropy is but a theory. A nice one, sure, but the universe may just as well be, well the universe. As in "all there is". Not that long ago, an anomaly in the CMB was theorized to be another bubble universe (all in the context of the M-theory, here synonymous with string theory, which by itself is under scrutiny as it seems to be impossible to combine with our reality) but that's all rather unproven, more in the realm of "Well, sure, this may be the case, but let's go with Occam's Razor first".

In other words, a universe in a state of maximum entropy spontaneously giving birth to a pocket universe isn't exactly impossible according to modern physics, but so is technically time travel (which just requires some exotic stuff with negative mass). In other words, not exactly the most likely of explanations.

What is definitely possible, are quantum fluctiations. Those are not only possible, but unavoidable. They however are rather locally confined, both in space and time. Tip: There's an interesting theory going on right now, the holographic principle. It's about using QCD on a 3D surface of a 4D spacetime (i.e. our universe) which by the merit of entropy (read: Thermodynamics) creates space-time curvature (read: General relativity). From what I get, this is still in it's infancy but it's a somewhat likely candidate for the theory of everything. Since it combines general relativity and quantum field theory (the 2 right but conflicting, yet both proven experimentally to exhaustion) using thermodynamics as a glue, that may be something.
