    That is like what might happen if our expanding universe is merely an expanding arena in a greater universe. When two similar expanding arenas intersect and overlap, there would be a gravitational effect in the overlap space like what is described in the article as "dark flow".

    My view of cosmology would be that when two expanding arenas overlap, the gravitational attraction between the galaxies in the overlap would lead to future big crunches.

    These are just ideas appropriate to this OP for discussion.

    So if there is another Universe out there and we're being drawn towards or into it, we should be able to head out towards the boundary and ultimately enter this unverse, leaving our own behind....

    Ask God. He might know what it is.

    Here's a curious note. We keep talking about this thing which we call "dark matter" and "dark energy". Could it be that those things are actually outside our universe and inside a bigger "universe"? Maybe our measurements show that there are other universes out there, and the collective mass and energies of ALL universes are represented by those "dark" variables with our visible ones! :itold:

    I speculate that dark energy accounts for how and why galaxies are moving away from each other. Dark matter cannot be directly observed because it gives off no radiation but it has mass and lingers within and around galaxies. They are two different things that affect every arena if there are multiple arenas as I speculate.

    The effect of another arena similar to our own expanding observable arena could account for the “dark flow” that you mentioned in your OP, i.e. dark flow effectively describes the effect on our arena if another arena were to come in contact with ours via an overlap during expansion.

    Multiple arenas, all part of a greater universe in 3-D space would have little direct effect on our arena except when arenas intersect, assuming that the cosmological principle holds true throughout the greater universe. By this I mean that if the greater universe looks essentially the same in all directions on a large scale, i.e. is homogeneous and isotropic, then where ever you look on a grand scale, there could be arenas in various stages of expansion, collapse, and overlap with other arenas.

    Speculation on top of speculation on top of speculation is fine fodder for free thoughts.

    Posts moved.

    You are the moderator. I think moving just my posts which were responsive to the originator and the OP is biased, but your status as moderator apparently lets you decide between speculation and over speculation.

    This is the thread in the Cosmology forum to which D H felt that I was being over speculative in my responses. He should have moved the OP here so my posts didn't appear out of context.

    Welcome to cosmology.

    Why? Cosmology IS part of that forum, right?

    D H has acted as if he is in the pocket of Prometheus and Alphanumeric in his dealings with me and has shown he will bow to their suggestions in place of thoughtful moderation. Will he continue to show favoritism and overlook bad habits by his favorites while coming down too quick on his favorite targets by employing “shoot from the hip” moderation?

    But you started this thread and asked for ideas. Do you have no opinion about the ideas that I posted that were found to be too speculative for a cosmology discussion at SciForums? Or can D H simply move posts he doesn’t agree with out of cosmology so they can’t be part of a discussion and by so doing chase people away from honest discussion?

    Has anyone given you a better answer to your OP than I did? Or did you want the standard answer, “We don’t know and you are not allowed to talk about it in Cosmology.”?

    The following link addresses what I was talking about. It was brought up by Kashlinsky before I mentioned it. I just took his observations and thought about what could cause the effect. D H knows better though and so again my ideas about cosmology have been deleted from his Cosmology forum. It used to be “our” Cosmology forum but moderation is being applied to keep me from discussion my ideas there. Someone is threatened by my ideas. Who though?

    http://www.newscientist.com/article/mg20126921.900-dark-flow-proof-of-another-universe.html

    Dark flow: Proof of another universe?

    Out of bounds

    So what is behind the dark flow? It can't be caused by dark matter, Kashlinsky says, because all the dark matter in the universe wouldn't produce enough gravity. It can't be dark energy, either, because dark energy is spread evenly throughout space. That, leaves only one possible explanation, he concludes: something lurking beyond the cosmic horizon is to blame.

    Before the findings were published in October in The Astrophysical Journal Letters (vol 686, p L49), Kashlinsky knew how heretical his idea would seem. "We sat on this for over a year checking everything," he says. "It's not what we expected or even wanted to find, so we were sceptical for a long time. But ultimately it's what's in the data."

    No one knows exactly what might lurk over the horizon or indeed how large the cosmos is (see "Just how big is the universe?") But Kashlinsky suspects it is a remnant of the chaotic state that existed just a fraction of a second after the beginning of time, before a phenomenon known as inflation took hold.
