question about "jets" from the center of galaxy's?

Question

Ok, I was told on another question that these jets are plasma from the accreation disk around the theorized black hole at the center. If thats true then why does it shoot out at such force? Shouldnt it be sucked in like everything else?

This is based on the 3rd answer...

Ok, so if the black hole were a basketaball and the surrounding stars were tennis balls. the T-balls would be rotating round the B-ball and then behind the T-ball followes other matter that would be like sand particles. Then when the T-ball is finally sucked in the sand has nothing to be attracted to anymore and since it was spinning so fast. Its then shot out at great speed?

Answer 1

Ok, this may take some time. Let's go back and review. In the beginning of the scientific universe, there were large areas of gas and matter kinda drifting around. As these clumps started to collide and grow larger, the core area began to become more and more dense. When these areas finally collapsed, they created black holes and quasars around these black holes. These black holes fed on their quasars like a huge vacuum machine. This suction led to an acceleration of particles in a circular fashion. This continued until the black hole completely consumed the quasar. When the quasar was gone, the black hole was unable to feed on local matter anymore. The circulation, however, is still going. This circulation compresses and glows brighter, obscuring the black hole from view. When some particles in this compressed disk reach the force needed to escape the gravitational pull of other objects it shoots out at near the speed of light. Imagine it this way . . . you have a pillow case and in this pillow case is a toaster, an object of mass. You start spinning this toaster and pillow case over your head. Your hands and the foce you're using to swing the pillow case and toaster are similar to the forces of the black hole and the pillow is acting as the hole's quasar. When you release the pillow, you have demonstrated the black hole's consumption of the quasar. For a period of time (remember scale here) the toaster will stay in orbit around you. On earth, it's a fraction of a second and a short distance, but in the big picture, its billions of years and in terms of lightyears. When the toaster finally leaves orbit, it and some of the matter that's attached to it will leave at a high rate of acceleration. That's why. Even though the force of the black hole is powerful enough to suck it in, the rotational force and the object's distance from the black hole are enough to keep it from being drawn into the black hole. I hope this helps.

Answer 2

The theory of blackholes is stupid, and the theory about why jets we can plainly see escaping these supposed blackholes is even dumber still. Gravity is not its own unique force, acting independently of all the other forces we know of. There is a single unifying force that holds matter together and it's the electromagnetic force.

What are these massive jets that we see, then? The same thing as static electricity, only on a galactic scale. Our entire galaxy is spinning around its axis, with the energy flowing in one side of the disc and flying out the other in a jet every once in a while when the attraction is so great. It is the same force that pulls our DNA and double-helix galaxies into the shape that they are in. What makes our planet rotate on its axis, and orbit the Sun?

Well our planet has a massive magnetic field, the Sun has an even bigger magnetic field, and when the solar "wind" comes flowing in like the bunch of charged particles that it is, we get big glowing rings on our poles called auroras. Everything is electromagnetics.

Answer 3

The jets are generated by the accretion disk, they do NOT begin inside of the event horizon. Bipolar jets or outflows are evident in pretty much every accretion process in astrophysics from protostars to white dwarfs in binary systems to blackholes. There is some indication that supernovas generate bipolar outflows (some explanations for some classes of gamma ray bursts are cosmological distance supernova with their poles oriented directly at us).

The precise mechanics for creating bipolar outflows is not well understood in ANY of these phenomena. Some leading hypotheses have to do with massive reconnection events in magnetic fields in the superhot-superdense plasmas in accretion disks as driving the episodic "bullets" in some jets. Keep in mind that the support for magnetic events driving solar flares and solar Coronal Mass Ejections is pretty strong, so this is not a big stretch.

I found a recent review article on galactic jets (aka AGN, Active Galatic Nuclei) http://adsabs.harvard.edu/cgi-bin/nph-bib_query?bibcode=2006MmSAI..77..598K&db_key=AST&data_type=HTML&format=&high=4498c914a228895 This is important because I have been out of touch with this stuff for a good 8 years now.

I can read the associated pdf, but my company might have an online subscription (and you might not). Still, give it a try. Section 4 in particular. You will need to look up a lot of words and acronyms, but you might be able to muddle through.

My quick read says that we still don't know, but the current thinking according to this guy is that the outflow originates via winds and is accelerated by magnetic events.

Answer 4

via fact the earth is the middle of our universe the Milky way is the galaxy on the middle. even though, each and every observer is likewise on the middle of the universe. So if somebody else asked this question from a miles off galaxy, to them, that galaxy could be on the middle.

Answer 5

feel_good is wrong.
>>>>>>>
Material in the accretion disk slowly spirals inward as it loses energy due to friction - the huge gravitational tides near the black hole are excellent at ripping apart this material and heating it to high temperatures. The inner disks of supermassive black holes reach thousands of degrees Kelvin (similar to the temperatures at the surface of a hot star), while smaller black holes can heat their disks to millions of degrees, where they emit in the x-ray part of the spectrum.

Black holes, therefore, are some of the brightest objects around. Quasars can be detected out near the edge of the visible universe, where they shine with the light of trillions of Sun, while microquasars in our own galaxy can easily be hundreds of thousands of times brighter than the Sun, even though they are typically only ten times as massive.

Answer 6

Think of it this way, you suck down an egg, you jet out some gas.

Answer 7

Plasma doesn't have enough mass to be affected by the gravity
