I Is the following a smaller version of dark energy?

    'Black holes banish matter into cosmic voids'
    http://www.spacedaily.com/reports/Black_holes_banish_matter_into_cosmic_voids_999.html

    "But Haider's team also found that a surprising fraction of normal matter - 20% - is likely to be have been transported into the voids. The culprit appears to be the supermassive black holes found in the centres of galaxies. Some of the matter falling towards the holes is converted into energy.

    This energy is delivered to the surrounding gas, and leads to large outflows of matter, which stretch for hundreds of thousands of light years from the black holes, reaching far beyond the extent of their host galaxies."

    No. It's just a movement of matter. It has nothing to do with dark energy.

    I don't see any link between that work and dark energy.

    Edit: @phinds beat me to it. Good dog!

    It's not just a movement of matter. The matter converts to energy. The energy then propagates through the black hole polar jet. The energy pushes the particles of matter, the gas, it encounters. It's not the same matter throughout the process. There is a conversion of matter to energy. The energy then pushes other particles of matter far beyond the extent of the host galaxy.

    Yes, and this has nothing to do with "dark energy", which is related to the expansion of the universe.

    If a black hole creates energy which pushes the particles of matter, the gas, far beyond the extent of the host galaxy could a Universal black hole be doing the same thing on a larger scale?

    The black hole doesn't create energy as much as matter gets converted into energy, which is no different than what happens in a nuclear reaction.

    No "universal black hole" has been observed, and the result of such a black hole expelling matter would be quite different from the observed expansion of the universe.

    Why would it be much different? What if there is no such thing as a great attractor (https://en.wikipedia.org/wiki/Great_Attractor)

    What if the Milky Way is getting pushed instead of pulled?

    "The survey also confirmed earlier theories that the Milky Way galaxy is in fact being pulled towards a much more massive cluster of galaxies near the Shapley Supercluster, which lies beyond the Great Attractor.[6]"

    You really would do well to read some basic cosmology before asking more question here. You would likely find that most of the questions you have now don't even make sense and would be cleared up quickly by reading the basics and you would be able to ask better focused questions that are not speculation.

    What doesn't make sense? A black hole emits energy into its polar jet which causes an outflow of the matter it runs into. This is exactly what is occurring at the Universal level. There is directionality to matter moving through the Universe. That's why the Great Attractor is theorized in the first place. Our Milky Way is theorized to be getting 'pulled' by something beyond the Great Attractor.

    What if everything is getting pushed instead of pulled, just like what is occurring in the polar jet of a black hole?

    It is an outflow of matter out of the galaxy. The matter is still there. All the energy is still there as well, everything just gets redistributed a bit. For the expansion of the universe on a large scale this is completelty irrelevant. And there is no push of any sort.
    Only on small scales. Well, "small" compared to the overall size of the observable universe.

    It's not the same matter that falls toward the black hole that is part of the outflow that extends far beyond the extent of the galaxy. The matter converts to energy. This energy then propagates through the polar jet. When this energy encounters particles of matter, the gas, it pushes the particles of matter.

    There is still directionality to matter moving through the Universe that requires an explanation. The notion of a "great attractor" and something beyond the "great attractor" pulling on the Milky Way are hypothesized in an attempt to explain this directionality. I'm suggesting the 'stuff' being hypothesized in order to explain the directionality is incorrect and an outflow from a Universal black hole also explains the directionality. A Universal black hole that is emitting energy into a Universal polar jet at relativistic speeds explains why the superclusters are accelerating away from each another.

    That does not matter at all. It is matter.
    No. The energy has been there before. It is just a conversion between different types of energy.
    This is a tiny local flow compared to the overall scale of the observable universe.
    There is absolutely nothing discussed in this thread which would in any way lead to a coordinated motion of anything. "A universal black hole" does not make sense at all.

    Anyway, if you want to suggest new things, physicsforums is the wrong place. We discuss established science only - things that appear in peer-reviewed literature. If you think you found something new, publish it, then we can discuss it. Otherwise we cannot. I closed this thread. Feel free to send me a message if that idea is published somewhere.
