Many worlds theory, many interpretations?

At Discover Magazine’s blog, “Cosmic Variance,” “Sean” asks “Are Many Worlds and the Multiverse the Same Idea?” (2011/05/26) ,

When physicists are asked about “parallel worlds” or ideas along those lines, they have to be careful to distinguish among different interpretations of that idea. There is the “multiverse” of inflationary cosmology, the “many worlds” or “branches of the wave function” of quantum mechanics, and “parallel branes” of string theory. Increasingly, however, people are wondering whether the first two concepts might actually represent the same underlying idea. (I think the branes are still a truly distinct notion.)At first blush it seems crazy — or at least that was my own initial reaction. When cosmologists talk about “the multiverse,” it’s a slightly poetic term. We really just mean different regions of spacetime, far away so that we can’t observe them, but nevertheless still part of what one might reasonably want to call “the universe.” In inflationary cosmology, however, these different regions can be relatively self-contained — “pocket universes,” as Alan Guth calls them. When you combine this with string theory, the emergent local laws of physics in the different pocket universes can be very different; they can have different particles, different forces, even different numbers of dimensions. So there is a good reason to think about them as separate universes, even if they’re all part of the same underlying spacetime.

Yes, he’s the Sean Carroll who wrote “No God Needed: CalTech physicist responds to Uncommon Descent’s questions,” shortly to become our fifth most-read post.

  1. Frankly, Sean, that’s a scary thought.

    I mean, the “reality” of the wavefunction was the reason for Everett’s “Many Worlds” hypothesis, where we wanted to somehow connect the math to the physics, connect the equations to reality. Everett accomplished this by assuming that the wavefunction *was* reality, but that there were many many realities going on. This is a metaphysical answer to the question “What has QM to do with Reality?”

    In contrast, the multiverse argument is that there necessarily exist all these multiverses, because there necessarily exist QM fluctuations that necessarily cause baby Big Bangs. At no point have we invoked a metaphysical question about “What is reality?” but instead have argued that everything is demanded by the physics. Supposedly, without any metaphysical theory of QM, the multiverses just sort of pop-out of the equations.

    Now admittedly, there’s a few more questionable assumptions in the multiverse theory, but none of them are quite the same as the QM conundrum where we have the math but not the physics. You might even say the multiverse is the opposite problem where we have the physics but not the math.

    So to claim they are the same thing, is to claim that multiverses come about by thinking deeply about the meaning of QM. My multiverse is not your multiverse, and my multiverse trumps your multiverse.

    Frankly, I find this very scary, because it says that metaphysics is indistinguishable from physics, that human consciousness can create many worlds, and Mary Baker Eddy was right. The man with the most powerful thought wins, let us call him the “superman”. Then what comes next, the super race?

  2. Everett’s “Many Worlds” hypothesis is falsified. First, the reason why Everett’s “Many Worlds” hypothesis was postulated in the first place was this,,,

    Quantum mechanics
    Excerpt: The Everett many-worlds interpretation, formulated in 1956, holds that all the possibilities described by quantum theory simultaneously occur in a multiverse composed of mostly independent parallel universes.[39] This is not accomplished by introducing some new axiom to quantum mechanics, but on the contrary by removing the axiom of the collapse of the wave packet:
    http://en.wikipedia.org/wiki/Quantum_mechanics

    ,,,Thus instead of dealing honestly with the clear Theistic implications presented by quantum wave collapse,,,

    ,,,the materialistic philosophy was forced into ‘unparsimonious’ quasi-infinite parallel universes,,,

    ,,yet quantum wave collapse is now shown to be instantaneous and universal for each unique point of observation in the universe,,,

    Wheeler’s Classic Delayed Choice Experiment:
    Excerpt: Now, for many billions of years the photon is in transit in region 3. Yet we can choose (many billions of years later) which experimental set up to employ – the single wide-focus, or the two narrowly focused instruments. We have chosen whether to know which side of the galaxy the photon passed by (by choosing whether to use the two-telescope set up or not, which are the instruments that would give us the information about which side of the galaxy the photon passed). We have delayed this choice until a time long after the particles “have passed by one side of the galaxy, or the other side of the galaxy, or both sides of the galaxy,” so to speak. Yet, it seems paradoxically that our later choice of whether to obtain this information determines which side of the galaxy the light passed, so to speak, billions of years ago. So it seems that time has nothing to do with effects of quantum mechanics. And, indeed, the original thought experiment was not based on any analysis of how particles evolve and behave over time – it was based on the mathematics. This is what the mathematics predicted for a result, and this is exactly the result obtained in the laboratory.

    ,,,Thus not only does Many-Worlds not have any empirical support in the first place, many worlds has in fact ignored advances in the double slit experiment that have extended the double slits veracity, and clarity, of clearly demonstrating that universal quantum wave collapse is a real event;

    ,,,Moreover,, this following experiment made quantum wave collapse much more ‘personal’,,,

    “It was not possible to formulate the laws (of quantum theory) in a fully consistent way without reference to consciousness.” Eugene Wigner (1902 -1995) from his collection of essays “Symmetries and Reflections – Scientific Essays”; Eugene Wigner laid the foundation for the theory of symmetries in quantum mechanics, for which he received the Nobel Prize in Physics in 1963.
    http://eugene-wigner.co.tv/

    Here is the key experiment that led Wigner to his Nobel Prize winning work on quantum symmetries:

    Eugene Wigner
    Excerpt: To express this basic experience in a more direct way: the world does not have a privileged center, there is no absolute rest, preferred direction, unique origin of calendar time, even left and right seem to be rather symmetric. The interference of electrons, photons, neutrons has indicated that the state of a particle can be described by a vector possessing a certain number of components. As the observer is replaced by another observer (working elsewhere, looking at a different direction, using another clock, perhaps being left-handed), the state of the very same particle is described by another vector, obtained from the previous vector by multiplying it with a matrix. This matrix transfers from one observer to another.
    http://www.reak.bme.hu/Wigner_.....io/wb1.htm

    i.e. In the experiment the ‘world’ (i.e. the universe) does not have a ‘privileged center’. Yet strangely, the conscious observer does exhibit a ‘privileged center’. This is since the ‘matrix’, which determines which vector will be used to describe the particle in the experiment, is ‘observer-centric’ in its origination! Thus explaining Wigner’s dramatic statement, “It was not possible to formulate the laws (of quantum theory) in a fully consistent way without reference to consciousness.”

    ,,, As well, Many Worlds suffers from the, ‘dissolving into absurdity’, problem that the multiverse scenario does;,,,

  3. As to Sean Carrol’s quote here:

    ‘When cosmologists talk about “the multiverse,” it’s a slightly poetic term. We really just mean different regions of spacetime, far away so that we can’t observe them, but nevertheless still part of what one might reasonably want to call “the universe.”‘

    (By this comment, ‘different regions of spacetime’, I take Carrol to mean different regions of the temporal spacetime of General Relativity)

    Yet, despite the materialists not having any evidence for ‘different regions of spacetime’, Theists actually do have evidence for ‘higher dimensions of space and time,,

    The weight of mass becomes infinite at the speed of light, thus mass will never go the speed of light. Yet, mass would disappear from our sight if it could go the speed of light, because, from our non-speed of light perspective, distance in direction of travel will shrink to zero for the mass going the speed of light. Whereas conversely, if mass could travel at the speed of light, its size will stay the same while all other frames of reference not traveling the speed of light will disappear from its sight.

    Moreover time, as we understand it, would come to a complete stop at the speed of light. To grasp the whole ‘time coming to a complete stop at the speed of light’ concept a little more easily, imagine moving away from the face of a clock at the speed of light. Would not the hands on the clock stay stationary as you moved away from the face of the clock at the speed of light? Moving away from the face of a clock at the speed of light happens to be the same ‘thought experiment’ that gave Einstein his breakthrough insight into e=mc2.

    ,,,Yet, even though light has this ‘eternal’ attribute in regards to our temporal framework of time, for us to hypothetically travel at the speed of light, in this universe, will still only get us to first base as far as quantum entanglement, or teleportation, is concerned.

    That is to say, traveling at the speed of light will only get us to the place where time, as we understand it, comes to complete stop for light, i.e. gets us to the eternal, ‘past and future folding into now’, framework of time. This higher dimension, ‘eternal’, inference for the time framework of light is warranted because light is not ‘frozen within time’ yet it is shown that time, as we understand it, does not pass for light.

    “I’ve just developed a new theory of eternity.”
    Albert Einstein – The Einstein Factor – Reader’s Digest

    “The laws of relativity have changed timeless existence from a theological claim to a physical reality. Light, you see, is outside of time, a fact of nature proven in thousands of experiments at hundreds of universities. I don’t pretend to know how tomorrow can exist simultaneously with today and yesterday. But at the speed of light they actually and rigorously do. Time does not pass.”
    Richard Swenson – More Than Meets The Eye, Chpt. 12

    It is very interesting to note that this strange higher dimensional, eternal, framework for time, found in special relativity, finds corroboration in Near Death Experience testimonies:

    ‘In the ‘spirit world,,, instantly, there was no sense of time. See, everything on earth is related to time. You got up this morning, you are going to go to bed tonight. Something is new, it will get old. Something is born, it’s going to die. Everything on the physical plane is relative to time, but everything in the spiritual plane is relative to eternity. Instantly I was in total consciousness and awareness of eternity, and you and I as we live in this earth cannot even comprehend it, because everything that we have here is filled within the veil of the temporal life. In the spirit life that is more real than anything else and it is awesome. Eternity as a concept is awesome. There is no such thing as time. I knew that whatever happened was going to go on and on.’
    Mickey Robinson – Near Death Experience testimony

    ‘When you die, you enter eternity. It feels like you were always there, and you will always be there. You realize that existence on Earth is only just a brief instant.’
    Dr. Ken Ring – has extensively studied Near Death Experiences

    It is also very interesting to point out that the ‘light at the end of the tunnel’, reported in many Near Death Experiences(NDEs), is also corroborated by Special Relativity when considering the optical effects for traveling at the speed of light. Please compare the similarity of the optical effect, noted at the 3:22 minute mark of the following video, when the 3-Dimensional world ‘folds and collapses’ into a tunnel shape around the direction of travel as an observer moves towards the ‘higher dimension’ of the speed of light, with the ‘light at the end of the tunnel’ reported in very many Near Death Experiences:

    The NDE and the Tunnel – Kevin Williams’ research conclusions
    Excerpt: I started to move toward the light. The way I moved, the physics, was completely different than it is here on Earth. It was something I had never felt before and never felt since. It was a whole different sensation of motion. I obviously wasn’t walking or skipping or crawling. I was not floating. I was flowing. I was flowing toward the light. I was accelerating and I knew I was accelerating, but then again, I didn’t really feel the acceleration. I just knew I was accelerating toward the light. Again, the physics was different – the physics of motion of time, space, travel. It was completely different in that tunnel, than it is here on Earth. I came out into the light and when I came out into the light, I realized that I was in heaven.(Barbara Springer)

    Also, hypothetically traveling at the speed of light in this universe would be instantaneous travel for the person going at the speed of light. This is because time does not pass for them, yet, and this is a very big ‘yet’ to take note of; this ‘timeless’ travel is still not instantaneous and transcendent to our temporal framework of time, i.e. Speed of light travel, to our temporal frame of reference, is still not completely transcendent of our framework since light appears to take time to travel from our perspective. Yet, in quantum teleportation of information, the ‘time not passing’, i.e. ‘eternal’, framework is not only achieved in the speed of light framework/dimension, but is also ‘instantaneously’ achieved in our temporal framework. That is to say, the instantaneous teleportation/travel of information is instantaneous to both the temporal and speed of light frameworks, not just the speed of light framework. Information teleportation/travel is not limited by time, nor space, in any way, shape or form, in any frame of reference, as light is seemingly limited to us. Thus ‘pure transcendent information’ is shown to be timeless (eternal) and completely transcendent of all material frameworks. Moreover, concluding from all lines of evidence we have now examined; transcendent, eternal, infinite information is indeed real and the framework in which ‘It’ resides is the primary reality (highest dimension) that can exist, (in so far as our limited perception of a primary reality, highest dimension, can be discerned).

    “An illusion can never go faster than the speed limit of reality”
    Akiane – Child Prodigy

    Logic also dictates ‘a decision’ must have been made, by the ‘transcendent, eternal, infinite information’ from the primary timeless (eternal) reality ‘It’ inhabits, in order to purposely create a temporal reality with highly specified, irreducible complex, parameters from a infinite set of possibilities in the proper sequential order. Thus this infinite transcendent information, which is the primary reality of our reality, is shown to be alive by yet another line of evidence besides the necessity for a ‘first mover’ to explain quantum wave collapse.

    As a side light to this, leading quantum physicist Anton Zeilinger has followed in John Archibald Wheeler’s footsteps (1911-2008) by insisting reality, at its most foundational level, is ‘information’.

    “It from bit symbolizes the idea that every item of the physical world has at bottom – at a very deep bottom, in most instances – an immaterial source and explanation; that which we call reality arises in the last analysis from the posing of yes-no questions and the registering of equipment-evoked responses; in short, that things physical are information-theoretic in origin.” John Archibald Wheeler

    Why the Quantum? It from Bit? A Participatory Universe?
    Excerpt: In conclusion, it may very well be said that information is the irreducible kernel from which everything else flows. Thence the question why nature appears quantized is simply a consequence of the fact that information itself is quantized by necessity. It might even be fair to observe that the concept that information is fundamental is very old knowledge of humanity, witness for example the beginning of gospel according to John: “In the beginning was the Word.” Anton Zeilinger – a leading expert in quantum teleportation:
