I used the earth as an example of how escape velocity decreases with distance from the surface.
I looked up Meng Su and found this: http://www.cfa.harva...2/pr201216.html
Where it starts to explain how the jets and bubles formed. The line: "The jets were produced when plasma squirted out from the galactic center, following a corkscrew-like magnetic field that kept it tightly focused"
is not talking about the black hole itself.
The infalling matter from the accretion disk heats up as it is subjected to frictional heating. Near the black hole it is hot enough to emit x-rays.
The co-aurthor of the article Douglas Finkbeiner of the CfA goes on to say: "The central accretion disk can warp as it spirals in toward the black hole, under the influence of the black hole's spin," and then:
"The magnetic field embedded in the disk therefore accelerates the jet material along the spin axis of the black hole, which may not be aligned with the Milky Way."
While this is currently the most accepted theory (more here: http://en.wikipedia....elativistic_jet) it still all happens outside the event horizon of the black hole.
Matter will still fall into the black hole, but before it does some of it escapes via these jets.
As for the bubbles (from the article above):
"The gamma-ray bubbles likely were created by a "wind" of hot matter blowing outward from the black hole's accretion disk. As a result, they are much broader than the narrow jets.
Both the jets and bubbles are powered by inverse Compton scattering. In that process, electrons moving near the speed of light collide with low-energy light,
such as radio or infrared photons. The collision increases the energy of the photons into the gamma-ray part of the electromagnetic spectrum. "
The actual article: http://arxiv.org/abs/1205.5852
observed galactic jets:
If by "how can the same galaxy suck in light, matter, & energy from both sides of the galaxy at the same time"
You mean the black hole at the center of the galaxy can suck in stuff at the same time as spewing out jets, that's explained above
and "and what happens to the material that is sucked in?"
Apart from adding to the black holes mass, I don't think anyone knows.
so to recap:
The jets are caused by the magnetic field of the accretion disc accelerating matter along the black holes rotational axis outside the event horizon.
Really? Here is what your source said: "Although accretion onto supermassive black holes in other galaxies is seen to produce powerful jets in X-ray and radio, no convincing detection has ever been made of a kpc-scale jet in the Milky Way. The recently discovered pair of 10 kpc tall gamma-ray bubbles in our Galaxy may be a sign of earlier jet activity from the central black hole."
Well, friend, one can't get any more 'central' than that. But in addition to this you have an even bigger problem because it is not just the area within the event horizon that you have to worry about.
Quote: "Rotating black holes are surrounded by a region of spacetime in which it is impossible to stand still, called the ergosphere. This is the result of a process known as frame-dragging
; general relativity predicts that any rotating mass will tend to slightly "drag" along the spacetime immediately surrounding it. Any object near the rotating mass will tend to start moving in the direction of rotation. For a rotating black hole, this effect becomes so strong near the event horizon that an object would have to move faster than the speed of light in the opposite direction to just stand still."
No matter how you cut it, light jets of energy and/or mass escaping from all of this is impossible. Yet there it is
. So how could the same forces pulling in the light/energy/matter inside of the black hole with an irresistible force drag the very same kind of light/matter/energy in the opposite direction to the tune of 27 million light years....in BOTH directions; all from a black hole (plus the ergosphere effect) from which nothing can escape? And...we are talking about more than a mere 8 million mile diameter event horizon.
The reason our physics isn't working in such anomalies is because God Almiighty is making it happen. It is caused by something beyond the natural and He has made it obvious.
Another thing: about your fourth source; quote: "What could be causing this flaring? "We do not know for sure yet," says Madrid, adding that there are two broad possibilities."
You left that little quote out. But also: "One is that material flowing down the jet is ramming into a cloud of dust or gas at the location of HST-1 and glowing. The other argues that the magnetic field lines that keep the jet focused in a beam may get squeezed together."
In other words, they don't know. Why didn't you tell us that? If I did such a thing as a creationist I would be accused of 'quote mining'. That's the way it usually goes.
But also, you said, "You mean the black hole at the center of the galaxy can suck in stuff at the same time as spewing out jets, that's explained above."
No, it wasn't. Quote them. And then explain to us why you believe them.
Lastly, "and what happens to the material that is sucked in?"
Apart from adding to the black holes mass, I don't think anyone knows."
So, you don't know what happens to all that matter after it is sucked in (from both directions!) while your comrades are honest enough to admit they don't know why the same kind of matter is shot out in the opposite direction and yet you are certain on this point
?Prove that the light jets originate outside the ergosphere....and then tell us how there is such a field of energy so far from the central core of the galaxy that can justify such a well directed double jet stream of light/matter.
But worst of all is what the scientists at MIT said about this: "Scientists can't pin down the process responsible for the bright radiation coming from
Sagittarius A*, but suggest it could be a powerful jet of particles accelerated by magnetic fields around the black hole, or radiation pouring out of an accretion disk of matter funneling into the black hole.
In other words they don't know either.
The quote with this picture says, "disk of material spiraling INTO black hole." Into? How can the light/matter be spiraling into
and out from
the black hole at the same time? You should be saying to yourself, "Houston, we've got a problem."
