Accretion Disc Same as a Spiral Galaxy??????
Just ran onto this little paper on BH accretion. It's a strong corrolary
to the MHD/ reverse-EMF "shear" mechanism suggested earlier. The accelerating inflows _have to be_ electric plasmas by dint of superheating. As such, they must generate enormous magnetic structures powering the MHD mechanism which drives the jets - http://cfa-www.harvard.edu/cfa/tad/e...tracts/35.html oc |

Accretion Disc Same as a Spiral Galaxy??????
Thanks oc I'm looking for gravity creating an EM force in accretion
disks to show gravity creates the electromagnetic force in the microscopic realm. This is what Einstien was trying to achieve. We have to remember he did not like blackholes,and that is why he missed the boat. He spent his last 35 years,and did not realize he needed a strong gravity forge in the micro realm to align particles to have a N and S poles,and keep the alignment. It is parrel lines of force that make a force greater. My theory is really starting to gel together. Bert |

My theory is really starting to gel together. =A0 =A0 Bert, all field theories are founded on the premise that space is functionally void or 'nothing'. That's why they've been unable to unify gravity and the strong force, and resort to complex mathematical constructs involving "eleven dimensions" and such. But if gravity is simply recognized for exactly _what it appears to be and behaves as_ , namely the flow of the spatial medium itself, unification becomes glaringly obvoius and requires no math whatsoever to convey in concept. When there's a spin component to the flow, the natural bipolarity of black holes' gravity and the proton's strong force becomes obvious, with clear-cut 'N' and 'S' polarities. That, in a nutshell, is the unification of gravity in the macro realm with magnetism and the strong force in the micro realm (under Wolter's CBB model, that is). That covers three of his Four Forces. The one remaining, electric flow, shows how the 90-degree relationship of electric flow in a conductor to the proton's N-S strong force is the basis of electromagnetism. But that's another chapter. oc |

Accretion Disc Same as a Spiral Galaxy??????
'Lo ya'll --
Bill, what you describe as the bipolar input to a black hole also makes me think of a nebula as it collapses to form a star and stellar system... It occurs to me that the collapsing cloud of gas and dust would leave behind huge amounts of scattered bits of matter and gas that would stretch out in all directions from the collapsing nebula. As the nebula collapses, it is believed to spin faster and faster. When the spin is fast enough (at some point *before* the collapsed nebula becomes a fusor, a star) an accretion disk forms at the equator. Within this accretion disk the dust begins to come together to form larger and larger discreet planets. Now, what about all that other matter that stretches out in all directions as well as the directions off the equator? The two possibilities seem to be (1) that it remains there for awhile with nothing to motivate it to come together to form anything, and then eventually, when the cloud fuses to become a star, it's blown away by the brand new stellar wind. and (2) perhaps this material is swallowed back into the quick-spinning nebula at the poles, drawn by the tremendous gravity of the newly formed (but not yet fused) spinning protostar? This second possibility would solve a problem i've been having with the amount of mass that it takes to make several huge planets at various distances from a forming star. I've never been able to picture the matter in an accretion disk to be enough to form all those planets. Yet... if matter from directions *other than* the accretion disk is sucked in at the poles of the spinning nebula, while matter continues to leave the nebula via the accretion disk, this might be enough mass to justify all the planets and other objects we have circling our Sun today? happy days and... starry starry nights! -- We move very very slow...

Nyet!! Nix!! No, Paine. Bipolar accretion would apply _only_ to black holes, not to 'normal' stellar bodies, protostars etc. The inbound material from the accretion disk falls _onto_ the star pretty much as the mainstream model depicts. Up to and including neutron stars, the infall goes 'onto' the star. 'Normal' objects having very high spin rates, such as the recently-discussed millisecond pulsar, would show the barest beginnings of gravitic bipolarity and the infall's beginning to favor the poles. The spin rate of BHs would be orders of magnitude higher, making them into full-fledged gravitic dipoles. The BH core of a Seyfert galaxy would be a good illustration of gravitic bipolarity. oc |

Painius, just to expound a bit more on gravitic bipolarity and how it's
rooted in the simplest of grade-school physics.. the Earth itself, due to its rotation, gravitates _slightly_ less strongly at its equator than at the poles. The difference is slight but measurable. The linear velocity at the equator is a tad over 1000 mph. Now ('thought experiment') picture the entire mass of the Earth collapsed to a pea-sized BH. Due to conservation of angular momentum, the equatorial velocity is now vectored onto the radius of a pea. What happens to the spin-rate? It goes astronomically high. With the equator now violently repellant to entry, by what route can the BH possibly gravitate (and accrete matter) except thru its poles? oc |
