Is Dark Energy A Larger Version Of The Energy Found In The Following Article?

'Black holes banish matter into cosmic voids'

"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."

 

At the scale of our Universe could the energy described above be what is referred to as dark energy? Could a Universal black hole be powering a Universal polar jet we exist in?

Cool article! :thumbs_up

 

To people who keep up with astronomy, it’s not surprising, but it’s good to see work being done to add galactic jets into computer simulations like the Illustris project.

 

At the scale of our Universe could the energy described above be what is referred to as dark energy?

No.

 

The energy referred to in the spacedaily article is ordinary mechanical energy due to the heating of gas near supermassive black holes, which is not fundamentally different than the hearing of gas within the cylinder of an ordinary internal combustion motor.

 

Dark energy is an ad-hock energy used to explain cosmic expansion. Where ordinary mechanical energy affects bodies in space, dark energy affects space itself.

 

Could a Universal black hole be powering a Universal polar jet we exist in?

No.

 

We have pretty good maps of the universe. Central black holes producing jets – active galactic nuclei – are very bright in distinct EM ranges. One big enough to be deemed “universal” – that is, much bigger than any other – would be hard to miss, and hasn’t been seen.

That's not what the article is referring to. As matter falls toward the supermassive black hole it converts to energy. This energy then flows through the galactic lobe. When this energy encounters the particles of matter, the gas, it pushes them.

The article is not just referring to a jet. It is referring to all of the gas being pushed far beyond the extent of the host galaxy. At the scale of the Universe the Universal black hole is outside of our visible Universe. The CMBR is more likely associated with an ongoing process than a 'bang'.
