Damn it all, I've got weeds in my garden to worry about, and now this....

No kidding!
Sounds like some kind of Multiverse land grab. Wonder if that scifi story line has been used before? :) |

Uncertainty may make you uncomfortable. Certainty makes you ridiculous.

| Maybe someone can enlighten me as to how this supports "multiverses" in any way, shape or form. All I see is mass flowing towards other mass(which happens to be out of our field of view) Still it is pretty cool that we can get SOME information from beyond the proverbial wall. |

Very funny. Praise Zeus that their snatched up from the dryer. If they were snatched before the wash they'd be sent back for their smell or before the dryer we would also be loosing water, not just single socks to,,, eh,,, somewhere. Isn't it so cool how all the universe and universes work so well together? Someday I'll get to sail there without crew.  SS |

Interesting!
The article stated that the gravitational influence extends to within "2.5 billion light-years from Earth."
I realize billions of light years is a staggering distance but 2.5 billion light years from Earth is a lot closer than the edge of the known Universe at approximately 13 billion light years. So if there are structures outside the view of the observable Universe tugging at matter 10.5 billion light years within the known Universe, that's a powerful influence! It seems that such a thing would have been detected long ago. |
Diversity, independence, innovation and imagination are progressive concepts ultimately alien to the conservative mind.

It doesn't. It's just bad science reporting. |

I think it's even more than that. The age of the universe is ~13 billion years. While nothing can travel faster than the speed of light (as far as we know), the space through which the light has traveled has expanded itself, so the distance that these objects is currently more like 46 billion light years away -- that is the boundary of the observable universe (in each direction). |

@BigPapaSmurf -- I really don't like the word multiverse, just because we haven't observed it, or even if "different universes" were separated by some sort of barrier, shouldn't mean, in my estimation, that it's "not in the universe." I would just replace that word here with "objects we haven't observed."
I don't find the suggestion that it could be caused by something outside of the visible universe to be overly speculative to merely consider (the article did say it was a controversial suggestion as it certainly isn't scientifically justified at this moment). It's just something that could explain the flow. Certainly it's possible that something in the underlying assumptions is mistaken. There definitely are things wrong with our understanding of physics that very well could sneak into our reasoning and lead to bad results here as elsewhere. |

No one is saying that stuff outside the visible universe isnt influencing us, the problem lies in the misuse/misunderstood term "visible universe". The VU is a sun centered golfball inside a basketball sized universe. The multiverse idea would be like a rack of basketballs.
Edit:I dont think it is even speculative, from our current understanding of gravity and the basic distribution of matter, "Dark Flow" is a certainty. |
