    Hi guys I m new to his forums o I hope I post this in the right place.

    I have a questions about the 11 dimension. As I saw some documentaries about M theory, it seems our universe was created by colision in the 11 dimension. So I was wondering how does it looks like. At the begining of big bang, there was Helium and Hydrogen that comes from Protons and Neutrons and they are created from Gluons and Quarks right ? So how far can we track the procces back ? What caused the colision that created big bang ? Is there also Dark Energy and Dark Matter, or its just in our universe ?

    Welcome to PF;
    M-Theory needs to predict everything that we know now - so it would look like just what we already see. Beyond that it is not really clear what you could mean.

    Wikipedia has a good introduction to the Big Bang theory ... also on the size of the Universe and the visible Universe. But you may mean: "are there any particles more fundamental to hadrons than the quarks and gluons 'inside' quarks and gluons"?

    Hmm then myabe a better question is ;

    What you need to create a big bang and how can you aquire that ?

    Yike!

    That's a highly speculative area and afaik there are only guesses.
    eg. you could maybe spawn a new Universe off this one if you can sufficiently bend the space-time. iirc that needs exotic matter ... I don't think the initial conditions for starting a Universe is something that you "acquire".

    A working GUT would help :)

    A big bang from the collision of branes is a braneworld M-theory model. However, since M-theory is still incomplete such models are more like guesses. The best one can do is try to answer your questions in a given framework.

    In the context of M-theory, in 11-dimensions, there are only a few "ingredients" at one's disposal to create quarks, leptons, dark matter, etc. As far as branes, one only has the two-dimensional M2-brane and five-dimensional M5-brane. By wrapping and/or intersecting these branes one can create objects that behave like electrons, quarks and dark matter in lower dimensions.

    There is no established understanding of what, precisely, caused the big bang. As mentioned in this thread, several candidate theories offer proposals, like brane collisions and bounces, but few if any of these models offer unique and definitive predictions that could be subject to scientific validation.

    There is no empirical evidence that there are any dimensions other than the 3 space and 1 time that we know about. Right now, the others are a mathematical device used by string therory. They MAY turn out to be real but they may not.

    Sounds like you want a forum about god, not an actual science forum such as this one. I object to your religious blather.

    Oh, English is not your native language, so "blather" might no be familiar to you. It means talking on and on and not making any sense.

    I add to this one : Even if there is more and more people on our planet and eventualy we will colonise the space with other spieces, who are certaiinly simliar since they had planet, evolution, social structure, music and the most important imagination and individual uniquenes, the universe will simply one day die out no matter what we do, even if we will be able to create new planets or stars, we will run out of material, our stars will die etc.. You cant create something from nothing, only if we are able to trigger another big bang and move there to contnue reproduce to infinite and beyond XD.

    Lets say we will be able to make sustainable enviroment with countinuesly triggering new big bangs to have place for our reproduction, we might even manage to keep people alive forever, BUT that inst a matter, becasue many many generations have already died does it mean they numbers in making larger volume of combinations had disapeard ? Ofcourse new people born so new numbers come along, but if we look at our universe it doesnt fall back in volume of combinations, right the oposite when a star dies something new is created etc etc, Even black holes adds new force to the combinations, nothing disapers the volume is simply only increasing.

    I DONT CARE about god lol... I care about his work.

    Do you think that the number of interaction in space is increasing or decreasing or is it stable ?

    Do you really mean to claim that you know the reason for existence?

    Not clear what you mean by "volume of combinations" ... we certainly see a lot of repetition of form on different scales - fractals and all. The total combinations are only going to be limited by the total energy in the Universe.

    What problem? Limited possibilities? Who says it's a problem?
    But life is limited by the same rules limiting the Universe
    No - actually our bodies are made of a subset of what the Universe contains ... we are made of the kind of particles found in stars.
    Of course not.

    nothing
    Which is to say, "nothing" - unless you can define your terms more closely...
    That remains to be seen ... but if the Sould is to be characterized as that which supplies emaginings, intellect, and so on - how is it different from "mind"? You appear to be expounding on the mind-body problem ... how can the materialism of empirical science account for the mind etc.

    We are working on it.

    Being able to imagine anything is not the same thing as having an infinite imagination. However, abstract concepts can be as big as we like without existing. It remains to be seen if the physical underpinnings of the human imagination can encompass an infinite potential to imagine.
    No you are thinking about mortality - we are also limited by being human ...
    Yes, I'm sure we can all imagine many fasle and untrue things. The trick is to tell which ones are worth imagining.
    Oh no - first an argument from complexity, then argument from the existence of the soul, now from first cause?

    But only "if" ... OTOH: if the Giant Spaghetti Monster is a perfection and cause of everything then we realy cant surpass this principle, because if we could it would mean we are more then GSM. We cant surpass him.
    ... see? I can make empty statements too.

    Well it lacks any empirical validity. On top of that - it contains assumptions that are simply not true in fact - like human bodies containing more types of particles than the rest of the Universe.

    Put in religious/creationist terms, human science is an attempt to understand creation in terms of itself ... as such, possible divine origins are not considered. We are confident in this because so many things humans used to think, in their error, to have only a divine explanation have turned out to also have one entirely within the Laws of Creation - which you'd think of as Gods Laws.

    To a religious person, it is often useful to think of science as an attempt to distinguish and study natural phenomena ...

    ... as a science forum, these metaphysical questions don't really belong here.

    Question has no meaning.
    I think your original question has been answered - if you have different questions, it will work better if you start a new thread.
    It will also help if you define your terms.

    This is a science forum. If you are going to posit a supernatural being, you have to justify it. Can you?

    I agree with the body think I made a bad example here ...

    No I dont know if its the truth LOOOOOL !!!! ( jesus told me yesterday ?) I just speculate can I But nevermind my "mess" has been deleted anyway so I think I should visit some other forums where people can "test their imagination".

    No there is no supernatural, everithink comes from something so I m sure physics will find an answer how to create something out of nothing to abadon this false concept.
