All this study does is prove "dark energy" is pervasive. It doesn't prove it's uniform throughout the universe. I suspect that more study will show that it's not a "cosmological constant", but a function of volume and density. The "emptier" space is, the faster it expands. Galaxies and clusters shrink while voids balloon. That would explain the structure of the universe without having to invoke "dark matter" or "inflation", or any of that nonsense.

Present something provable and repeatable and you have yourself a debate. Simply stating something that has been observed and repeatably tested is wrong is largely void of mass, (doesn't carry much weight).

So, they're saying dark matter/energy is a force, such as gravity?
Dark energy is the name given to an unexplained force that is drawing galaxies away from each other, against the pull of gravity

There are many assumptions noted in the article, too; if some are off just a wee bit then more cogitation by the cosmologists will be necessary.
Wouldn't one expect the early universe to expand faster? In the very earliest moments gravity had less time to act. Maybe the greater density counteracted that tendency, but that's for the cosmologists to say.

I don't think it's so difficult to prove. Just build the 30-Tesla field strength super-conductor magnet disk, and spin it. Or do it with a spinning super-conductor plasma, like AlienScientist.com describes. The Dark Energy should be produced (according to Heim theory) from the magnetic field breaking open the (normally closed) extra dimensions of space-time, that Dr. Michio Kaku also speaks of.

Astronomers know dark matter is there by its gravitational effect on the matter that we see, and there are ideas about the kinds of particles it must be made of. By contrast, dark energy remains a complete mystery. The name "dark energy" refers to the fact that some kind of "stuff" must fill the vast reaches of mostly empty space in the Universe in order to be able to make space accelerate in its expansion. In this sense, it is a "field" just like an electric field or a magnetic field, both of which are produced by electromagnetic energy. But this analogy can only be taken so far, because we can readily observe electromagnetic energy via the particle that carries it, the photon. Some astronomers identify dark energy with Einstein's Cosmological Constant. Einstein introduced this constant into his general relativity when he saw that his theory was predicting an expanding universe, which was contrary to the evidence for a static universe that he and other physicists had in the early 20th century. This constant balanced the expansion and made the Universe static. With Edwin Hubble's discovery of the expansion of the Universe, Einstein dismissed his constant. It later became identified with what quantum theory calls the energy of the vacuum.
If galaxies clusters are plasma pinches in vast cosmic fillamentry currents, the natural result is long range attraction and short range repulsive forces. This can explain what is called the great river of galaxies, the great attactor and dark flow, and the very fillamentry structure of the galaxy clusters all without the need for invented forces.
