    This may or may not be relocated to Trash, I'm just flexing my imagination muscles here.

    From what I understand, M-theory proposes that spacetime has 11 dimensions, of which only 4 constitute our Universe (3 space and 1 time).

    I was thinking about how earthquakes happen, two tectonic plates rub against each other, building up pressure until that built-up pressure is released as a (potentially quite violent) tremor.

    Could something similar have happened within spacetime where "friction" (for lack of a better word) between a few of the 11 dimensions built up pressure that was eventually released in a tremor that we refer to as the Big Bang, a sort of "versequake"? Three of these 11 dimensions became distended into what became "our" Universe where the remaining dimensions in our region of spacetime retained their contracted state?

    If this idea (not even a hypothesis at this stage) has any merit, could it then be plausible that other spacial Universes could arise from other areas of friction-tremor-distension regions of spacetime, albeit not necessarily with 3 spacial dimensions?

    Not an unreasonable Idea. I don't have any clue about how we would prove it though. There is a general problem with testing the prevasive normal conditions of the universe. The multiple other dimensions are a bit like that. They are part of what "just is".
    But ... the paleoentoigist Tiellard de Chardin, looking at the march of evolution over time, preposed the "law of complexity-conciousness". His point being, as I understand it, that the laws of thermo dynamics ought to have just resulted in a homogeneous uniformly distributed universe, but did not. He theorised that there was needed another operating condition to explain reality. Something that drove reality toward everincreasing complexity and conciousness.
    This force or law of existence is so prevasive that we can't separate it from any part of existence so as to test for it. The way we can move something and observe it moving or heat something and observe it cooling.

    Deacon, its as plausabile of a definition as any other I have heard trying to tie together m-theroy with the singularity event of our universe.

    Issues however, would be testing & prooving it. Best case secnario i see, is having a working mathamatical model. Worth persuing if you have the ability to do so.

    Thanks for the "vote of confidence"

    Unfortunately I know even less about mathematics than I do about physics, so I wouldn't even know where to begin constructing a model for such an idea.

    In connexion with your musing, you might find the ekpyrotic universe idea of interest.

    Probably your best course of action is throw it out on the web, perhaps a science related forum & hope someone "big" notices it worthy enough to run with it.

    That is kind of what I'm hoping for.

    One thing that could maybe come from this idea is the inflationary period could be the equivalent of a "versequake" aftershock*, and the amount of energy/matter in our Universe could be a direct result of the magnitude of the quake, following E=mc2.

    *If there was a discrete period of time between the Big Bang and the start of Inflation (I'm not sure if that is a definite theory or not,) otherwise perhaps instead of an instantaneous Big Bang, the versequake lasted about 10-33 seconds in duration - the same length of time as the Inflationary period.

    But then again, I may be stretching the analogy to breaking point.

    I probably should have put this in the personal theories subforum.

    Could I get it relocated please?

    I do see many similarities between my idea and the Ekpyrotic Universe hypothesis, which I guess in a way is encouraging (it means I'm not a complete crackpot... yet).

    In the Ekpyrotic scenario, are both the branes considered to have three dimensions, or just the one in which our Universe resides? What of the other brane, does that have another Universe of its own?

    Would both branes have to be perfectly parallel to each other to account for a single instantaneous "big bang" as opposed to an ongoing one?

    The Branes take 5 dimensions, but I am not up on M-Theory enough to tell you about it.
    It would be better if somebody more familiar with it explained it because I would likely get it wrong and cause confusion.

    M theory and string theory are complete speculation. Actually, the degrees of freedom are so huge, that its impossible not to find infinite M theories that describe our universe.

    Why not 37 dimentions? Or maybe more kinky 69 :P ? 13 is too unlucky!
    Why not a million? ....Lets not be shy and just shove infinite dimentions in there, it will sure cover our backs that way.

    I don't think that's completely true.

    There has to be a lot of valid mathematics involved for M & String theories to be considered reasonable hypotheses.

    I'm not an expert on these theories, but I agree with your comments about post 13.
    Also I believe the word is "dimensions" and not "dimentions" which has been used twice.

    Or letís just say this universe is being fueled by an infinite supply of dimensions and the consumption rate creates mass, gravity, space, and time.

    It wouldn't, YangYin just makes up gibberish which he sprinkles on word salad.

    What are we talking about when we say Branes or singularities? What is a dimension? Does it take energy for dimensions to exist? Do collapsing or expanding dimensions create cause and effect? If so a three dimensional collapse in a sea of infinite foam of three dimensional spheres could be a starting point. One collapsing sphere pulls on surrounding spheres and they disconnect and begin to collapse pulling on surrounding spheres and so on. Like throwing a stone in a still pond only each ring created creates a three dimensional collapse. If dimensions contain energy this system would have the ability to build upon itself through collapse and expansion and would continue until all was put back as three dimensional spheres of foam in an infinite state.
