    No it had nothing to do with your fetish.

    How many 'multiverses' ( :rolleyes: ) are there?

    A) Doesn't exist and B) its the single worst thing that Star Trek every did with their story lines.

    As this entire concept is hypothetical we might as well go to the extreme because it makes no difference to our reality. I suppose it means that an entire Universe is created every nanomicro plank second as every creature thinks everywhere and then this process is repeated in every created universe every micronano plank second for every new creature as it thinks and makes new universes….rinse and repeat.

    True. But there would be infinitely many such universes.

    Well, since the universes are quanta and are countable, i suppose N-0. (Sorry, no aleph or subscripts on my phone)

    Generally I think people agree. But there is this answer

    Interesting...but, if space itself is "quantized" using the Planck length, even the infinite number of states of position would be countable, wouldn't it?

    I think so. And even for something like energy states or momentum, everything still comes in discrete states. Time is quantized. And they are all limited. But I'm still stewing on it. Does there exist a function space with an infinite number of dimensions? Or is that a purely mathematical concept. I tend to assume the latter.

    But time may be infinite... I remember a lot of integrals said so! :D

    To the poster who was asking about a recent shakeup to the scientific thing I found a part of a video explains that a recent work challenges our theory of string theory.

    Very sloppy and inaccurate! She states that dark energy is the explanation for the universe "slowly expanding". NO! It is thought to be the reason the expansion is accelerating. In fact dark energy is the name applied to whatever reason exists for the observed acceleration.

    The expansion of the universe has been known since Hubble first measured the red shift of distant objects, and the paper by Lemaître in 1927. Until we discovered the acceleration, it was assumed that the expansion was decelerating due to gravity. The expansion was thought to originate with the Big Bang.

    An interesting note: The expansion was assumed to be decelerating but it could have been accelerating. The margin of error in the measurements allowed for both possibilities. But that didn't make sense so we assumed it was slowing down or had stopped. When we were finally able to measure accurately enough to detect the acceleration, they gave the explanation a catch-all name - Dark Energy. We don't know what it is but we see the effect.

    Yes that is a reality seen in much of academia. Sheldrake talked alot about this same thing in The Science Delusion.

    While a biologist, with credentials, he also is educated at Harvard in the history of science, which gives him a view here that most people in science just do not have.

    I just read his book again and not much has dsince his countless astute observations made in that book. People who scoff at this scientist can only do so because they know so little about him. What he has done in the field of biology and his education on the history of science that he is a part of. He got into trouble by simply questioning the dogma present in belief systems, of scientists, many of them.

    No. I posted several links about evidence for a multiverse.

    So scientists have tested it, and found evidence? How would you go about that, outside of the math saying it is possible? The key word here is...possible.

    So what can they do, in technology with this theory? Can it be applied? Has it been applied? Or even tested for that matter? My understanding is that these kind of ideas cannot be tested. Is that not true? And since when?

    Sorry man, I do not use those sources for science info. Got a credible one? Many times these popularizers are not accurate.

    You got a real deal scientist who has at least written on this?

    And the reason that I ask, is I just heard Sean Carroll say, that these ideas cannot be tested. And if they cannot be tested, then that ends it, right there, for me. I am not a scientist, but do trust those that are, what they say on this issue. And from what I can tell, all of them say what Carroll just said a couple weeks ago.

    The multiverse has as much evidence and makes as much sense as this video:

    Yes, theoretically mathematically.

    Unless time and space were truly infinite.

    There is a little problem. Where does that choice actually come from? If everything were completely deterministic, with known cause and effect, then everything should be completely predictable, no probabilities.

    That outside influence that seems to affect probabilities appears to be the "quantum vacuum", the unpredictable nature of space itself with tiny fluctuations.
    Since probability results in superpositions, it might be reasonable to assume that the fluctuations of space exist in superpositions as well.

    I know that may sound strange, how can the space around us exist in undecided superpositions when we are existing in it.
    Well here's something else to consider: Waves of light can still exist in superpositions even when they pass through a transparent medium like a glass prism (it is believed, I'm not sure there has actually been a specific single-photon experiment carried out to verify this). The critical factor is the degree of interaction. So long as the degree of interaction is low, the wave-particle can still maintain its undecided state.

    There is another theory as well. That is that time may not be just a one-way street. In that case, rather than just continually branching off into infinite possibilities, those possibilities might ultimately coalesce back into fewer probabilities. A form of coherence.
    Take two probabilities, two things that could have happened but ended up having the exact same outcome. You wouldn't know which of the two had actually happened. In fact there could be a strong inherent tendency for the "multiverse" to remain coherent into just one form.

    All you have to do is check the source of the article. :rolleyes: Unless you have a journal subscription... Do you really expect to be hand fed?

    Two physicists won the Nobel prize for demonstrating the existence of an electron in two places at once. This from 12 years ago.

    This quotes the abstract from the paper published in the journal Science
    http://science.sciencemag.org/content/272/5265/

    This paper rules out the last possible prosaic explanation for the cold spot indicating a parallel universe

    But it isn't. So what's the point?
