Both cases, says physicist Brian Greene, are possibilities, but if the latter is true, so is another posit: There are only so many ways matter can arrange itself within that infinite universe. Eventually, matter has to repeat itself and arrange itself in similar ways. So if the universe is infinitely large, it is also home to infinite parallel universes.
Does that sound confusing? Try this:
Think of the universe like a deck of cards.
"Now, if you shuffle that deck, there's just so many orderings that can happen," Greene says. "If you shuffle that deck enough times, the orders will have to repeat. Similarly, with an infinite universe and only a finite number of complexions of matter, the way in which matter arranges itself has to repeat."

In a two-dimensional representation of the brane-inflation scenario, two nearby branes, each itself inflating, are drawn together and annihilate, creating a mass of subatomic particles and energy that eventually coalesces into our universe, driven to expand by the tremendous release of energy from the annihilation. Theory predicts that the process created huge cosmic strings that exist in dimensions outside our three that might be observed by new gravity-wave detectors.
http://www.news.cornell.edu/stories/March06/Tye.brane.ws.html
"Imagine little flat people living on the surface of a piece of paper. Just the surface: their world is not even as thick as the paper, with no vertical dimension at all. Stick a pencil through the paper and all they would see is a circle, a two-dimensional cross section. Fold the paper or roll it up, and they wouldn't know the difference.
Now you're ready for brane-world theory, which proposes that our three-dimensional universe lies inside higher spatial dimensions, and we are no more aware of them than those flat people are of our third dimension. Since a membrane separating two spaces is a handy example of a two-dimensional object in three-dimensional space, theorists started referring to a plane as a 2-brane. By analogy, we live in a 3-brane. (Although we have four dimensions if you count time, as physicists do.)
Brane-world theory is a subset of string theory, which proposes that quarks, electrons and other elementary particles are not really tiny spheres, but actually tiny strings. They don't look like strings to us because we see only three dimensions, and strings exist in many more -- 10 or maybe 11. We're just seeing a three-dimensional cross section."

Brian Greene is one of the easiest string theorists to understand, but this line of thinking still does not explain how our particular universe, with its coherence among the micro (quantum), meso , and macro scales and its finely tuned cosmic values came to be. String theory definitely has a few promising notions going for it including hyperdimensionality and the vibrational nature the fabric of reality. But these theories in no way can be considered a true theory of everything, since they only try to comprehend true nature of reality in a limited physical sense. Some new conception of field theory and information is needed. If pondering about the metavere/ multiverse interests you, please check out the work of Dr. Ervin Laszlo ( I can send you two of his ebooks for free if you want). He has come up with the Connectivity Hypothesis and is author of more than 60 books. His theory boils down to the role information plays in the dynamic and evolving relationship between the cosmic plenum (usually misnamed the quantum vacuum) existing is a non-vector, scalar, potential, and virtual state, giving rise (literally in-forming) to all fields of known existence of a vectorial nature from the quantum field to gravitational, electromagnetic, spinor, tensor, the strong and weak fields, and the torsion field to name a few. He implies that a new information field underlying all of reality is capable of explaining all phenomena of coherence (non-local) connections. There is a feedback loop in which information is conserved and transferred from the virtual cosmic plenum to manifest reality and back. Each time the new reality is generated it is capable of fine tuning itself according to what information from the past version of itself had been fed back in to the plenum. So this framework can explain how our universe came to rise with the capability of creating sentience and all its splendors. All of this occurs in a holographic nature (think of Bohm's implicate order). One must also adopt the cyclic model of creation within the larger framework of the metaverse.
So, for a second, imagine the universe as an evolving, learning entity (simply put but not simple, a coherent quantum information processor). Within the framework of the metaverse, there lies the potentiality of any possible universe to give rise. Once one universe rises as a flux of probability within the cosmic plenum and manifests to physical reality, it will live its life (estimated to be one trillion years) with its selected cosmic constants of a particular value (some combinations like that of our current universe will allow formation of matter, and thus us). Upon its death (whether in the crunch or freeze), all possible information from that system will have been given to the cosmic plenum ... acting as a first draft. Then a new probabilistic fluctuation occurs within the plenum/ vacuum, allowing for the manifestation of a new universe, building off of what the previous version of itself had learned. It is truly in-formed by the metaverse. As the universe manifestation cycles continue on, the probability of a universe arising with its cosmic constants so finely tuned that it can give rise to matter and an observable, biologically friendly universe increases with the number of cyclic lifetimes. So there is a learning curve. And since this process is the phenomena of creation, it is observable at any scale of reality from the quantum, biological and ecological, to cosmic proportions. His theory helps to really expand on biology and evolution, working in conjuction with Rupert Sheldrake morphic fields and the work of Bruce Lipton and Mae-Won Hoe. Well, I hope this made sense to somebody.Here is Ervin Laszlo's website, http://ervinlaszlo.com/ and if anybody is interested in these types of materials, I have a huge library of ebooks I am willing to share.

I know of no 'explanation' of how matter come into 'being' ---'being' being the term given existence itself. There are only two possibilities ---matter ALWAYS existed and that is forever beyond either mathematics or philosophy to 'explain'; and 2) matter came into existence from utter 'nothingness' and that is, likewise, beyond anything existent to explain. As the emperor Augustus was fond of saying: "Words fail me". Not only words but numbers fail us.

I agree that the human mind, even with mathematics, is not capable of understanding "all that is", but that does not hinder us from understanding many of its physical processes.This is an explanation of how matter can come from a virtual state to a real state of physicality based in the transfer of scalar informational waveforms to a vectorial, observable state. Nothing is created, but only observed and brought into physical realization. This cosmic plenum had already been experimentally observed since the 1950s, an undebatable fact. All i read about is this type of material, and of the hundreds of books I have read so far, Ervin Laszlo has the most comprehensive and well documented theory. Check out the connectivity hypothesis. Its a 120 page paper, and
I'l share it if you want. - 1 year ago

echelgreen:
Understanding 'many' is not the same as understanding 'all'. Secondly, no one really knows what it means for matter to '....come from a virtual state to a real state'. Anyone claiming that they understand it doesn't really understand it. The sentence "Nothing is created, but only observed and brought into physical realization" moreover implies in the phrase 'nothing is created', that everything that is always was! And if that is the case, no one can explain that either. All we can do is label objects or processes of which we can be sure exist empirically. But we are forever unable to explain 'nothingness' with 'something' and words --being 'somehing' --are only meaningful to the extent that they represent things that are already known to exist.

In no way do I disagree with you. I am just putting forward someone's hypothesis to explain the emergent phenomena of coherence within an information driven cosmos. In no way do I believe that science and mathematics will ever be able to explain everything. I am just offering a model that has practical applications to the real world. And when I mentioned the realization of a a physical state from a virtual, a polarization between scalar potential and physical fields ... this has been empirically demonstrated and a nobel prize won for it. Energy was successfully extracted from this cosmic plenum I speak of. It has influence of physical processes. The full extent of this is definitely far from understood and I agree, that it might never be fully comprehended as well. Bottom line, I am completely aware of the limitation of rational knowledge through the scientific method. It is only meant to explain a small sliver of total reality. But this physical plenum of nothingness, teeming in virtual probabilistic states does have an observable effect on physical reality, literally in-forming it. That is the only point I was trying to make. It is an indirect knowledge of this plenum.

Indeed, I hope I did not state the case too strongly. Obviously --we are both on the same side of the equation here. I suppose it just demonstrates the difficulty that 'humankind' has always had with respect to 'nothingness' and 'ultimate origins'. The mind boggles and, as Augustus said 'words fail me'! He is not alone. On this issue --words as well as equations fail everyone.

He made some good points in his interview on TCR about a larger perspective, as the current conception of the universe being only part of a larger continuum.

Greene blew Colbert's mind with the idea that there might even be a parallel universe where Taco Bell actually serves beef in their food. He even gave Stephen a great pickup line with "You are a bag of particles governed by the laws of physics"

The way Greene explains it joins Julian Barbour's theory on the non-existence of time.
http://discovermagazine.com/2000/dec/cover
A very interesting article. Excerpt:
That sounds reasonable, as it should, coming from a thoughtful gentleman like Barbour. But the next part of his argument— the crux of his view— is much harder to swallow: Every possible configuration of the universe, past, present, and future, exists separately and eternally. We don't live in a single universe that passes through time. Instead, we— or many slightly different versions of ourselves— simultaneously inhabit a multitude of static, everlasting tableaux that include everything in the universe at any given moment. Barbour calls each of these possible still-life configurations a "Now." Every Now is a complete, self-contained, timeless, unchanging universe. We mistakenly perceive the Nows as fleeting, when in fact each one persists forever. Because the word universe seems too small to encompass all possible Nows, Barbour coined a new word for it: Platonia. The name honors the ancient Greek philosopher who argued that reality is composed of eternal and changeless forms, even though the physical world we perceive through our senses appears to be in constant flux.
Before allowing himself to be interrupted by the stream of questions he knows will come, Barbour continues to press his point. He likens his view of reality to a strip of movie film. Each frame captures one possible Now, which may include blades of grass, clouds in a blue sky, Julian Barbour, a baffled Discover writer, and distant galaxies. But nothing moves or changes in any one frame. And the frames— the past and future— don't disappear after they pass in front of the lens.

Right on. I share the exact same view. I propose it is our consciousness that acts as the projector, choosing which slide, or "Now" so to choose. But the film is being read at one frame per 5.39124 x10^-44 seconds (the Planck time). In our current state of consciousness we just string these "now's" together in a fairly linear way to make sense of our chosen reality. And the term Platonia is sweet. I am definitely adding that one to my standard vocabulary.

In a parallel universe we are all less skeptical and have no political differences. The bad news is we have nothing to talk about ;)

Shortly after the discovery of Andromeda galaxy n the early 1900s, 'Galaxies' were often called 'Island Universes'. They were, rather, cloudy, spiral-shaped objects not unlike our own Milky Way and far beyond it. The man who is credited with changing our view of the universe is the American astronomer Edwin Hubble. Utilizing what was then the new 100 inch (diameter of the reflecting mirror) telescope on Mt. Wilson in CA, he photographed the 'great nebula' in the constellation Andromeda. His historic images revealed that Andromeda was not a nebula but a galaxy and not unlike our own Milky Way. By definition and according to what we know of our own universe we should not expect to see another universe. The question is whether our own universe is 'closed' i.e, light does not escape it but instead finds its way back to its origin; ergo: if the Starship Enterprise continued indefinitely upon a straight path, it would find its way back to its point of departure due to the curvature of space-time itself. If such curvature of space-time is the defining characteristic, then we may never expect to see another 'universe'.

Back in the late sixties when I was living in Cambridge (England) I had a South African friend named Roger Clegg who was studying mathematics. He at that time created quite a stir when he came up with a mathematical equation which proved the existence of a parallel universe. I don't know what has become of him, I left Cambridge shortly after that.
