    Universe Tugged by Mysterious 'Dark Flow'
    Larry O'Hanlon, Discovery News

    Sept. 25, 2008 -- Astronomers have stumbled upon an unexplained two-million-mile-per-hour sideways shift in the universe toward a colossal, unseen, unknown gravity source beyond the horizon of the observable universe."

    What do you think this is!?

    I think someone flushed the galactic toilet.

    I made a thread about this a few months ago or something. I think James R and a few others who were quite knowledgeable spoke about them. Sorry for my being a 12 year old at the time and being incoherent, though :\.

    If our universe collided with a neighbor universe in higher dimensional continuum would this impact cause destruction in one particular region or would it effect all our universe at the same time?

    The universe gets more interesting every day! =)

    You are 13 ?

    Hi Psyclon. The same topic is discussed here. However the answer to your question would require speculation and my habit of piling speculation upon speculation has caused D H to have to move my posts to never-never land and my threads to Pseudoscience, and rightfully so.

    Since we have no evidence of "higher dimensional continua" and we can't detect them what makes you think there'd be any effect?

    I’m going to answer Psyclon's question and I am thinking that it is OK to do so here because I don’t think it is too speculative to discuss a collision of universes in a forum dedicated to Cosmology. If I’m wrong then D H will move my post or the thread. If he moves the tread I would suggest Pseudoscience and if he moves just my post as he did on this thread previously, I would ask him to make a note here this time pointing to where ever he moves this post. But that is only a request and he is the moderator and therefore he decides and I accept.
    A scenario where two "universes" collide is speculative, but we don't need to pile the speculations to the point that we invoke a "higher dimensional continuum". Such a collision could occur in plain old 3-D space if our observable universe is only a tiny patch of space in a greater universe that is characterized by similar expanding universes. There is little evidence of even that scenario but it could explain "dark flow" mentioned in the OP.

    So avoiding the reference to other dimensions, if our expanding arena were to collide with another expanding arena in 3-D space, the two arenas would intersect and overlap. The space involved in the overlap would be lens shaped and would contain galaxies and galaxy groups from both arenas. In that lens shaped space the galaxy groups from each arena would interrupt the expansion momentum of the galaxy groups in the other arena and a swirling and mixing of galactic material would occur.

    The galactic material in the overlap would begin to collapse or rotate around a new center of gravity due to their mutual gravitational attraction. This collapse would be progressive across both arenas as the overlap progresses. So IMHO, the effect of the collision of two universes, which I refer to as separate arenas, would not effect the entire arenas at the same time, but the effect would occur over the time period related to the relative momentum of the two intersecting arenas and the portion of the arenas that get caught up in the overlap.

    The collision could be head on in which case eventually both arenas would be substantially effected, or the collision could be a passing glance in which case it is possible that a substantial portion of each arena would move on away from the collision leaving behind a swirling patch of galactic material rotating around a new center of gravity.
