The power of spin

(PhysOrg.com) -- Supermasssive black holes - objects with masses of millions or billions of suns - are found at the nuclei of dramatic galaxies like quasars where they are responsible for some of the most spectacular phenomena in the cosmos.

Their environments can, for example, generate narrow jets of particles that can travel across thousands of light-years of space at nearly the . These outflows, discovered at radio wavelengths, are thought to be powered by matter accreting onto a hot disk around the black hole. The physical processes that drive these jets and cause them to radiate are among the important outstanding problems of modern .

One of the primary mechanisms thought to drive the outflows is matter accreting onto the vicinity of the black hole, during the course of which radiative and mechanical processes power the jets. But can spin, and a single can store as much energy as our Milky Way galaxy has radiated over its lifetime, or even more. CfA astronomers Brian McNamara, Paul Nulsen, and a colleague compare examine this vast energy source to see whether it might also be able to power such jets.

The scientists examined clusters of bright galaxies with active black holes in them. They considered the amounts of molecular gas available in these clusters for accretion onto the nuclear black holes, and compared the results to their model of spin-powered jets. They conclude that a spin-based scenario is consistent with the observations, although not necessarily better than accretion model. Although further clarification of the role each plays probably needs to wait until additional data can be obtained from new radio facilities, the new results show that spin is indeed an option that astronomers need to consider.

No, it is the power of neutron repulsion that is being observed.

Neutron repulsion is explained in this video:

A thought that occurs to me (and maybe hopelessly outdated, please indicate if it is).
Could there be a maximum of energy and mass) to what a BH can store, i.e. a ciritcal mass. Could this be a new big bang because of the enourmous amount of energy.
The bigger the BH, the larger the event horizon etc. But in time-space, it is a "well" (gravity well). How much would it take to make a bubble of its own in this time-space (as a drop of water falls in a puddle, it path is clear, creating a "well" and afterwards a "bubble" under water). Im not hinting to pathways to other dimensions but at storing energy and the effects of it.
Looking forward to hearing other thoughts.

Thecis,

Neutron repulsion probably prevents the formation of Black Holes.

But neutron repulsion also causes fragmentation (fission) of heavy nuclei and massive neutron stars.

That is probably why the universe seems to be fragmenting.

Omatumr,

At this moment there is more data to support the theory of black holes than there is of neutron repulsion. Perhaps (if that is easier) we can make this a thought experiment with the parameter that BH do exist.
What would your professional opinion be about my ideas as explained as above.

With kind regards,
Thecis

btw, just a thought. If neutron repulsion is so strong that it can withstand the pull of gravity, why do atoms exist then. One can see the that large atom(core)s do become instabile but if the repulsion is so strong, this should also be observed with with atoms such as carbon, oxygen, nitrogen, etc
