    From what I understood the noise comes from the "outside" fringes of space, the other direction of where they were trying to get information from the direction of the "big bang" (perhaps just the super-primordial-"quasar" which formed most the the matter in our "known" space).

    Outside the known universe. "Big Bang" direction is IN (indeed the center) of the known universe.

    An infinite length of time could not have transpired prior to THIS moment. Which means that there had to be a period of no time, or stasis, in the past before which nothing else happened. A perfect void is the only way to reconcile the paradox. Therefore ex nihilo becomes the only logical explanation for the origin of all things.

    It's wrong because some of the WIMP theories of dark matter predict that it can interact with itself and decay.

    The term is WEAKLY interacting, not non interacting.

    And for the record?

    plasma is Baryonic matter - it's baryonic matter missing electrons.

    Because you can't fulfill an infinite sequence.

    My usual thought experiment is this:

    God will create the universe after he drinks an infinite number of cups of coffee. How long will it be before God creates the universe?

    The answer, whether it is coffee or femto-seconds is: Never.

    Wow, that shows great imagination.

    Though if God chooses any time, then it would be created anyway.

    Ah.. but you see, you are assuming the infinite amount of time before now had a beginning.
    As long as infinity + 1 is valid an infinite amount of time could have gone by before this moment.

    No I'm not. If it had a beginning there would be no problem.

    If you couldn't see it with the coffee... try this:

    Starting from this moment in time, start traveling back into the past, one second at a time, until you get to the very beginning.

    That's right, you can't get there. In fact, there are an infinite number of "seconds" that you can not reach and never will. Now imagine that we started at one of these "impossible to reach" moments and started traveling forward. We would just as quickly discover that we will never reach "now" going in that direction.

    The only way out of this paradox is to tell me that if we started traveling into the past we would ever reach every single moment back there. Since we would both agree that this is impossible (there is always an n+1 moment out of reach), then we can say the same is true in both directions.


    Cyperium, I appreciate your input but you do not seem to understand what "time" is.

    Yes you can, an infinite amount of seconds later.

    See above.

    I don't think this is how it works.
    It doesn't matter that it took time an infinite amount of seconds to get to this moment, because it's been busy for infinity to get to it.
    By the way, I can prove that time has always been

    That would create a fulfilled infinite series, which is impossible.

    You are basically claiming that traveling into an eternal past would eventually get you through every moment possible. Which would imply an end to the journey. Which would imply a beginning. Which we have stipulated does not exist.

    I hope you will think on this some more, because your grasp of the concepts is not complete.

    You don't want my proof ?

    Anyway, I will think on it some more. I admit I'm not seeing the full picture right now. But I also have a gut feeling that your explanation is not correct. I'll get back to you on this later

    Any time. Debates about the infinite and the infinitesimal are my absolute favorite. And I really enjoy debating with you. It is funny how I absolutely agree with you on some topics and couldn't disagree more on others. Just don't ever take me too seriously.

    I guess it's safe to say that the early universe was indeed, a very noisey and violent place with all of the fireworks going off all the time.

    Ok. You say time had a beginning right ?
    Wouldn't it then be logical to say that time always was ? There was never a time when there was no time.. you follow ?

    So if time has always been that means that the universe has also been forever already. This is not an argument for time being infinite btw.

    Just out of curisity, what is your definition of 'Time'? If we're all talking about 'Time', we need to know what it is that we're all talking about. You know what I mean? By the way, what 'Time is it'? I mean 'Galaxy time', 'Universe time' or 'Big Bang time' or is it 'Universal tme'? I'm getting confused here. O.K Just tell us what 'Time' is. That should do for starters.

    Imagine I slip a sleeping pill into your drink and put you in a room without windows. When you wake up you won't know what time it is, or what day, but you can still tell that time is going by when you move your hand in front of your face.
    In other words, relative time (bit of a pleonasm there

    Darn! I always thought it was the 'Time' it takes to go from one event to another. How could I have been so wrong. I suppose I didn't take the 'Time' to really find out. Joke's on me I guess.

    Time is the time it takes to go from one event to another ? That makes no sense.

    O.K. How much 'time' does it take you to go from your house (one event) to the nearest ATM (the next event)? Maybe 10 minutes? Or in 'Galactic' terms, How long did it take the (1st event) fuse (once God lit it) to burn before it (the second event) actually blewup (the Big Bang)? It get's pretty simple after that.
