    I've just typed up a quick article on the topics of cosmological boundary conditions because I was asked by a non scientist (biblical scholar) about how the Universe began and why scientists feel they are right about the Big Bang.

    Enjoy!

    At present we cannot know how the universe began but just make informed guesses. There are many christians working in astronomy and cosmology but none have yet been able to point to anything and say with proof that that is God's work.

    If a God existed, then he would surely work by natural means since living an infinitely long time, he would have no need to hurry, as in the six day myth. Billions of years would mean nothing to him. Christians believe that he started life off, or even set conditions right for it to start off, which allows them to accept that he then used evolution to eventually bring about Man.

    Thats it, we can only go back to one Planck time after the so called singularity...obviously new theories/models/physics are needed.

    The thing that gets me is the anthropic principle, and then we have the resonant state of carbon which...blows my mind certainly. The grand scheme is so complex, we must be just one of many billions upon billions of Monoverses (spll?).

    Short answer -- nobody has a clue what the initial conditions of the universe were or why they were whatever it is that they were.


    It is quite clear from observed conditions, general relativity, and the empirical support for general relativity that the universe was in a VERY compact form about 13 billion years ago. That is called the big bang. What happened at precisely time 0 is a complete mystery.

    all the possibilites that have been thougt of to date and that are considered worthy of consideration. Those are probably overly inhibitive constraints.

    I have to disagree on that Ophiolite.

    Interesting. So you think the authors have been able to anticipate the full range of intitial conditions, including those that will only become viable upon clarification of other aspects of cosmological theory? That viewpoint does not seem consistent how all science has worked in the past. What makes you think it will work that way in the future?

    Correct me if I am wrong, but we can only have three types of space-time curvature, k=-1, k=0 or k=+1...and the initial conditions work within this set of curvature parameters. What does the CMB say about curvature...that space-time is flat.

    I understand what you are saying, not ruling anything out as yet. But I probably should of outlined that in my article...possibly I might re-write some of it tonight.

    Am in a sense, with ophiolite here. The history of science is littered with
    arrogant assumptions that reason and logic as we understand the concept,
    is the be all and end all. Does it not occur that our intellect is as yet,
    limited. We make up theories to explain what we do not understand, in some
    kind of conviction that we can grasp what is, at this time, beyond explanation,
    and our ability to understand it.
    As for you, Michael, trying to give answers to a man of the cloth, leave you
    with this, a man convinced against his will, is a man of the same opinion still,
    Nokton.

    Michael_Roberts. A few thoughts.

    The problems with the origin of the universe is where did it come from? No answer other than guesswork. Or why it came?

    What "came"? Everything that now exists, but we cannot be sure in what form as we are not quite sure of all that exists.

    What form? A singularity is just a black hole with magical properties. Hawking realised that some years ago and dumped it but many still hang onto it. Could it have appeared gradually over time and over a huge area, which would solve a number of problems like gravity?

    Inflation? Unproven idea used to explain smoothness of the universe but since it would be expanding into literally nothing and with no bias, it would naturally be smooth (like tossing a penny a trillion times. You will end up with virtually 50% heads and 50% tails, with differences iron out).

    Expansion would take place in four physical dimensions, as in a hypersphere since if it was 3D, we could trace it back to a point of origin.

    I take your point Michael,and have a sympathy with it.
    Brane theory was proposed, it has its merits, but it is
    at best, just a theory.
    The point I was trying to make, was this. Mankind, as a
    species, has reached a state of intelligence never seen before
    in an evolution of species on this planet.
    The evolution of intelligence is just that. An ongoing scenario
    where the human mind at any stage thinks it can provide an answer
    to any question that is proposed. Have we not the humility to sometimes
    say, we do not, and cannot, understand.
    Nokton.

    I can't think of anyone (scientist or other individual whose views I respect) who believes that the human mind is able to "provide an answer to any question that is proposed".
    There are many questions which we are unable to answer, but to say that we "cannot" understand implies that we will never have the ability to answer some of them. Given time, and assuming the survival of our species, I find it almost impossible to believe there are any questions we will not be able to answer.

    Hey!

    Apologies for not replying sooner, I have been without the internet for a few days.

    The fact of the matter is, many people will debate what has been presented in my article. Singularities, inflation and the initial conditions.

    What we do know is that the mathematics that describe what we take for granted nowadays (such as the Big Bang) came before they were analytically described to the waiting public. They were formed from Einstein's masterpiece that still hasnt been observationally disprooven. Hawking used this work to forumlate all the possibilities, such as the curvature of space time. The curvatures are assigned three possibilties, 0, inwards, and outwards. The degree to which space curves is not known but still doesnt hinder the mathematics greatly.

    From the CMB we see that space-time is flat, zero curvature. Hence, k=0. This has been observed and mathetically modelled.

    So to answer most people's input, the picture on the initial conditions is pretty well understood. And hence the cosmological model is well in place. Try and displace it, but try to do so via a new comprehensive framework. But currently, one is in place, and many cosmologists and theoretical physicists agree with it.
