    From your link:

    'The universe’s greatest game of spot the difference goes on. The next hotly anticipated experiment is over at ALPHA, where CERN scientists are studying the effect of gravity of antimatter – trying to answer the question of whether antimatter might fall ‘up’."


    (Boldface mine.)

    This could explain why "angels" "fly".

    What I read is that those measurements showed that the "magnetic moment" is the same, nothing more. There is no doubt that there is asymmetry, there IS a preference for matter (and we even know the ratio). The only question is why.

    Every time I hear that question, I think, well, maybe it [antimatter] didn't exist yet.

    Not to say I have a clue - way out of my league - but the question always pops into my head.

    Another interesting thought. If the universe was at one "time" an 11-dimensional hyper-surface that collapsed into the 3+1, as mentioned, how do we know the change all occurred in one event? Perhaps it occurred step wise. What's more, since the universe is assumed to be infinite in this model, then it seems unlikely that the process is one way. Perhaps the universe oscillates or simply switches between different states having different dimensions and different fundamental forces. This would seem to be more consistent in a universe thought to be infinite. So who knows? Maybe next week we will wake up and have four spatial dimensions and none of the appliances work. :D

    You need to get off of this idea that the universe was 11 dimensions and then it collapsed into 3.

    The universe still IS 11 dimensional, and that's just a minimum. There might be more dimensions.

    That comes from String Theory. I didn't pull this out of thin air. :rolleyes:

    The other 7 dimensions manifest as the fundamental forces - so goes the hypothesis.

    Also, we do not have 11 spatial dimensions. We have 3, and 1 temporal dimension. That's what we mean by 4 dimensions or 3+1. The others are at this point purely mathematical concepts.

    String theory says that the universe has 10 spatial dimensions, three of them expanded into macroscopic size and six remaining small. So it is more accurate to say that the universe expanded into the 3+1 dimensions, rather than collapsed. Why three dimensions expanded, and not some other number? Some scientists speculate that it is because 3-dimensional space is the only space where a string can tie into a knot.

    The universe exists because God was liberal instead of a conservative loner, and God doesn’t want conservatives who are worse than Hitler to put them in cattle cars for orderly disposal, even when “liberals” are by definition open-minded to banging for nothing.

    which would mean you not responsible for past actions, only future actions

    Whoa... very true. The philosophical implications are staggering.

    There's not really a consensus on this, but the latest research suggests that 5 of those extra dimensions curled up and 1 is actually super large. But, yeah, it's interesting stuff. Out of the different candidates for a theory of everything I'd hedge bets towards superstring/m theory being the closest to reality.

    Well yes, of course it could be that we don't know which particles existed during the early Universe, or at least that's what this article has me thinking:

    After series of experiments, scientists conclude that 'the universe should not actually exist'

    Not only do we not know why it exist, but you also don't know what happens when you die.
    Two mysteries for ya.

    So have I several times, one being out of body, ever had one of those?

    Yes, I've had out of body experiences when I was younger, but not recently.

    I have too, my last and only OBE was in 1984. Also why I know there is a spirit world and the universe is connected to it.

    I comfortably live with both mysteries since I have arrived at plausible answers to both, albeit without proof but sufficient evidence for my purposes.

    It was created and/or appeared so I could experience a failing and painful body. How is that for an egocentric and narcissistic answer?

    You paraphrase Moi.

    It is Moi's Universe.
    No Moi, No Universe.
    Questions.


    Being Matter o fact does not make me egocentric or narcissistic.
    Truth Happens.
