Hubble Images Solve Galactic Filament Mystery
NY Times ^ | August 21, 2008 | KENNETH CHANG

A tangle of spidery filaments stretches outward from the giant elliptical galaxy NGC 1275 as if they were dendrites of an intergalactic nerve cell.

NGC 1275, located 235 million light-years from Earth near the center of a clump of galaxies known as the Perseus cluster, has posed a puzzle: How have these filaments, which are made of gas much cooler than the surrounding intergalactic cloud, persisted for perhaps 100 million years? Why haven’t they warmed, dissipated or collapsed to form stars?

Images taken by the Hubble Space Telescope, with 10 times the resolution of earlier photographs, reveal that the filaments, about 1,500 light-years wide and hundreds of thousands of light-years long, are themselves made of finer threads – smaller structures about 200 light-years wide and 20,000 light-years long. The cold gas is pushed out by waves of radiation emanating from the giant black hole at the center of the galaxy. Small is relative, of course. Each thread contains as much mass as one million Suns...

They "solved" the mystery of what keeps the larger filamental strands cohesive... by finding smaller filament strands inside them.

BULL PUCKY!

That doesn't solve it, it just refines the mystery even further!

Perhaps if they considered a force 39 orders of magnitude stronger than gravity, they might start to get a clue as to what keeps the strands together.

I think that is what their letter said. Not sure how you get “magnetic fields in the threads” without a flowing electic current.


Letter
Nature 454, 968-970 (21 August 2008) | doi:10.1038/nature07169; Received 3 March 2008; Accepted 10 June 2008

Magnetic support of the optical emission line filaments in NGC 1275The giant elliptical galaxy NGC 1275, at the centre of the Perseus cluster, is surrounded by a well-known giant nebulosity of emission-line filaments1, 2, which are plausibly in excess of 108 years old3. The filaments are dragged out from the centre of the galaxy by radio-emitting ‘bubbles’ rising buoyantly in the hot intracluster gas4, before later falling back. They act as markers of the feedback process by which energy is transferred from the central massive black hole to the surrounding gas. The mechanism by which the filaments are stabilized against tidal shear and dissipation into the surrounding extremely hot (4 107 K) gas has been unclear. Here we report observations that resolve thread-like structures in the filaments. Some threads extend over 6 kpc, yet are only 70 pc wide. We conclude that magnetic fields in the threads, in pressure balance with the surrounding gas, stabilize the filaments, so allowing a large mass of cold gas to accumulate and delay star formation.

Black holes emanate waves of radiation? Hawking "evaporation" sure, but black holes are radiation suction points, not radiation emanation points.

Black holes do emit radiation. It’s called Hawking radiation after its discoverer. Apparently, it is produced by the rotation of the black hole or some such method.

Thanks for the quotation from the Nature letter.

Orthodox Cosmologists have yet to make that leap from the existence of magnetic fields to what causes magnetic fields. It is the flowing electrons that make them possible. They are not a static condition absent the presence of magnetized materials. It is surprising how often cosmologists are willing to assume "magnetic fields" as a way of explaining something they have not been able to understand, yet still shy away from allowing for flowing electricity causing those magnetic fields.

Gee! Maybe we don’t need “Dark Matter” after all! ;-)

We are still not sure about the energy emanations around black holes. It’s like for fusion, when the resulting product actualy loses mass and emanates resulting energy but yet gains density and keeps apparent original particle integrity in the said compressed biparticle core.

A siamese type fusion does require less skin and works with shared subparticles/organs despite being two distinct entities. Blackhole thermodynamics could warrant such algebraic losses.

As to what keeps the filaments together, I think they’d support string theory, a sort of longitudinal blackhole and refurling of the universe from 2 dimention to 1 instead of zero as in the case of a black hole. It could help understand the duality of light. It has wave characteristics that makes it unparticle like, and, that is, it is not possible to go 90 degrees from itself except in particle form, a sort of pseudodimentionality

These folkes assume it’s an emanation. Did they verify the direction of travel of the particles along these filaments. Some parts behind could go towards it, like in the case of tornado or hurricane walls showing a downpoor at the sides but up suction at the center.

“Black holes emanate waves of radiation? Hawking “evaporation” sure, but black holes are radiation suction points, not radiation emanation points.”

The black hole itself isn’t radiating, it’s the material falling in from the surrounding area. This material typically forms an “accretion ring” at the equator (spin axis), and since it’s falling all the way to where the gravity is strong enough for the escape velocity to be nearly speed of light, the material is going almost the speed of light when it hits the other matter in the accretion ring. That causes intense heating in the ring, which is what powers quasars (at least that’s the leading theory and I believe it;). The reason the black hole at the center of our galaxy is “quiet” right now is there is no material left in the vicinity to fall in. It most likely used to be a quasar.

Hawking radiation is a quantum effect that gets much stronger as the mass of the hole gets smaller. It’s intensity relates to the strength of the tidal forces near the event horizon. Large black holes like those at the centers of almost(?) all galaxies produce very little Hawking radiation.

In zero gravity atmospheric patterns are nonexisting. The universe displays strange patterns implying the existence of huge masses or forces.

If that is the photo, then to me, it doesn’t look like a filament. It looks like you are sighting across a surface.

I heard that 1 pound of dark matter weighs over 10,000 pounds.

well, in a way that's exactly what they are.

My aha moment came when I realized that matter is just higher frequencies of the Electro Magnetic field.

When Feynman casually mentioned that if you had two grains of sand, one completely positively charged and the other completely negatively charged, thirty meters apart. There would be a force of three million tons between the two.

Keep up the posts Swordmaker, I greatly appreciate them and my altered thinking : )
