Dark matter, dark energy…and now, dark flow

800px-Big_bangIf this doesn’t boggle your mind, your mind is un-boggleable (Via Space.com):

Patches of matter in the universe seem to be moving at very high speeds and in a uniform direction that can’t be explained by any of the known gravitational forces in the observable universe. Astronomers are calling the phenomenon “dark flow.” The stuff that’s pulling this matter must be outside the observable universe, researchers conclude.


A theory called inflation posits that the universe we see is just a small bubble of space-time that got rapidly expanded after the Big Bang. There could be other parts of the cosmos beyond this bubble that we cannot see. In these regions, space-time might be very different, and likely doesn’t contain stars and galaxies (which only formed because of the particular density pattern of mass in our bubble). It could include giant, massive structures much larger than anything in our own observable universe. These structures are what researchers suspect are tugging on the galaxy clusters, causing the dark flow.

“The structures responsible for this motion have been pushed so far away by inflation, I would guesstimate they may be hundreds of billions of light years away, that we cannot see even with the deepest telescopes because the light emitted there could not have reached us in the age of the universe,” Kashlinsky said in a telephone interview. “Most likely to create such a coherent flow they would have to be some very strange structures, maybe some warped space time. But this is just pure speculation.”

Even though I was a teenager in the 1970s, I don’t say this very often, but…far OUT!

And I mean that literally.

  1. Colour me boggled…

    Also, one Banker to another Banker circa 2005:

    lolz. Finance humour.

  2. Shoot up in two shotgun in space from two different places in the same area. Shotguns the distance is perhaps a hundred meters and the shot from the same region the same time as 10 kilometers away, after which they will continue to divergence and journeyed quite the same direction. Part of haule, however, goes a different direction, even if all shot to continue their journey away from the same area from where they were shot at moving!

    If the second shotgun shot yet haulinsa slightly faster circulation, and perhaps a bit later, so avot.

    Now, just think of a galaxy shell a set of galaksy stars were born only because the area where the shot come from the same region.

    Shotgun illustrate the huge energy mergers which are the shot came, but so that they do not drive their own power, but only the pushing of force based on the fact that energy turns into a normal high density of less energy when the gunpowder explodes noticeably!

    A change of power in the high density of less energy, when the gunpowder explodes noticeably?

    If so, why should space to expand, although the energy is expanding noticeably mode, which does not change?
