You mean spent 22 years in Florida dodging paying your bills and the 
law. Finally you had to skip the state so as not to ever pay up.

Sure he did. All those lefties like you LOVE free government money to 
steal. Florida is full of Dems bilking Medicare for stuff they say 
people got but never did. I'm sure you were in on that one!

I know what you mean Comrade, A black drug using school boy can hardly 
walk around one of your Jewish owned gated communities attacking people 
without having someone defend themselves. I noticed you are white and 
Democrat and hence are racist and hate blacks. Democrats have done a 
good job destroying the black community with their lies.

Obviously you are of the HVAC school of facts. Facts are Dems are all 
FOR slavery. GOPers took your slaves away. Dems INVENTED Jim Crow. Dems 
FOUNDED the KLAN. Dems opposed, the vote for women. Dems Robbed entire 
country of all gold. And that is FACT.

The Trump return that came out showed that Trump paid taxes for that 
year. YOu Dimocrats just tell lie after lie. I've never seen such 
dishonest people. YOu conspiracy theory "returners" are just howling at 
the moon. You got nothing. Like all Dimocrats you've spend your whole 
life mooching off others and still are living that way. The only way 
there are 4500 pictures of Grey Cloud out there is if you stole the 
copies. You obviously would never PAY $450 at 10 cents a copy EVER. 
You'd steal them instead. I'm still waiting to buy one of your M&M 
filters. When is it ready?

Bert is up in his high horse again. Let me knock his halo a bit. When Bert's wife got senile, instead of caring for her, Bert shipped her off to a nursing home that smells like old person pee.
She begged him to sign her out but Bert didn't want any part of dealing with her. She was old.

So, matter becomes jets when it falls into
a Black Hole. 
And light just gets spun so fast that it can't get out.
That's what becomes the accretion disc.

BZZZZZT! Wrong, try again. Why not do at least a little reading about these things, rather than just make crap up as you go along? these references may not be perfect, but they are much farther along the road than your own pathetic speculations...

Why are you so unwilling or unable to learn?  If matter falls into a black
hole, it can't get out, not as a jet or anything else (ignoring trivial
Hawking radiation).  The jets come from the inner accretion disk, not
the hole itself.

>And light just gets spun so fast that it can't get out.
>That's what becomes the accretion disc.

That's really stupid, even for you.  Accretion disks are just matter
spiraling into the black hole.  The extreme gravity heats and compresses
the matter to extreme temperatures.

And you know this how?
And how does this accretion disc matter
get accelerated to .9c?
Please explain.

Do you not understand the conversion of
 potential to kinetic energy?

Which is which? They saw a star orbit
more and more rapidly around a BH,
and then it shredded,
and then jets formed as soon as it shredded.
Where is the potential and where does it
convert?

Unlike you, astronomers have models of how they believe the universe works.
These models either directly or through computer simulations, show what
should happen given certain initial conditions.  These models predict
acceretion disks around black holes, which are very violent places with
extreme temperatures.

These models and simulations, including the effects of GR and powerful magnetic
fields, then go on to predict that some of the (extreme) kinetic energy of
plasma in the disk expels some of the matter from the disk violently
(~90% of c) at right angles to the disk.  And what we observe seems to match
those predictions quite well.

You don't know the difference between potential and kinetic energy? Sheesh.

Pick up a rock and hold it high. It took energy for you to do that.  If
energy is conserved, where did it go? The rock now has potential energy,
it has energy that can do something.  Now let go of the rock. It starts
to fall, to move faster. The motion is kinetic energy.  As it smashes into
your foot, the kinetic energy becomes work it takes to smash your toes. :-)

A star nearish a black hole. It has potential energy that can be released
by falling toward the hole. As it falls toward the hole (not directly but
in some sort of decaying orbit) some of that energy becomes kinetic energy
in the form of the velocity of the star.  The star orbits faster as it gets
closer to the hole.  Like the moon, it takes a month to orbit the earth
but the much closer ISS takes only about 90 minutes to do so.

Separately, go look up "Roche Limit".  As something that is held together
by gravity only (such as the star) gets too close to something more massive,
tidal forces start to tear it apart. You say "shreds".  Doesn't have to be
a black hole, think of the rings of Saturn which may have been from a moon
within Saturn's Roche Limit that got shredded.  (Or at least the Roche Limit
prevents the rings from forming into a new moon).

A star too close to the black hole is tidally disrupted and it, too, forms
rings around it.  Those rings are called an accretion disk.
As the matter in the accretion disk gets squeezed and heated, the jets
form as some of the matter is expelled from it and forms jets.

What is "lame" about that "ending"?

(not that you ever answer why you think something is wrong or whatever,
so I don't expect an answer to what is "lame" or why)

Anyway, laws of physics don't care what you think is "lame" or not.  If
the intense gravitation, magnetic fields and heating cause jets of matter,
there will be jets of matter, regardless of what one insignificant
creature on a distant planet considers "lame".

Are spiral galaxies the ones with accretion disc? Does the BH with the strongest gravity force have the biggest disc? How fast does this disc spin? Does it spin in the same direction as the BH?What is the distance it orbits from the BH? I have a thought that the disc is very magnetic,and has a great plasma electric field .Much like the surface of a star.Good reasoning tells me this is realty.TreBert
