Where's your evidence that jets are coming from black holes, rather than 
from their vicinity?

Black holes are a theoretical construct. The theory says that they don't 
radiate. An object that radiates cannot be a black hole. Calling it a 
black hole makes as much sense as calling a dry depression a puddle 
without water.

Faced with strong evidence that some object is a black hole, but with 
heat coming from its direction, the most likely explanation is that the 
heat is coming from something between us and the black hole.

As for the beams - the thing about them is that they look bright when 
they're pointed at you, and dim, or invisible, when they're not. So a 
beam can be of constant strength, but still appear to vary.

Logical thinking on display.  I like that. 

There is generally a dearth of it in here.

Or.
The ‘theoretical construct’ is based on a wrong interpretation of gravity, and there ARE no black holes.
There are, instead, these vortices at the centers of galaxies that are simply spinning Space, where Space is understood NOT to be empty but rather composed of smaller and smaller versions of matter.

the 'theoretical construct' is in depth complicated mathematics mostly
completed about 1976.

your "smaller versions" of matter may be what a neutron star is composed of.


event horizon is that pesky (-1)^(0.5)  problem.

Your evidence? Standard gravity works VERY well, there's no need to change
anything other than someday connecting it to quantum theory (a holy grail of
physics for a long time).

>and there ARE no black holes.

Again evidence? GR predicts them, there are many observations of things that
really cannot be anything other than black holes, in particular SGR A*.

Babbling nonsense. How can nothing spin?

So not "spinning space" but your mythical smaller levels. Of course no
evidencevwhatsoever for any smaller (or larger) levels of anything.  It's
nothingvmore than a Little Phama induced hallucination or something.

_Sgr_ A*.  “Sgr” is the abbreviation for the constellation “Sagittarius”,
and those abbreviations are at most written in CamelCase (like “UMa” for
«Ursa Maior» “the Great Bear”, containing the asterism “the Big Dipper”).

such as matter spinning around the black hole

these were called Quasars in the past, the beams are redirected
matter/energy sprayed out the ends of s spinning black hole, none of
that matter/energy went into the black hole, just gathered up near the
surface and spun on out the ends.

How? Magnetic fields can be very strong in one place and weak
somewhere else. Think of the nearest hospital with a MRI machine.
Magnetic field there is strong, magnetic field at your house not so much.

And what's wrong with hot things being near the black hole? Especially
if the hole's gravity is what's doing the heating, as stuff starts to fall
in?

>Where's your evidence that heat is coming from a black hole? "

>When it walks like a duck

That's your evidence? Walking ducks? Science would want observations of
where the heat is coming from.

They TheThem had just started sharing information regards newly
discovered objects that were spewing jet streams, in opposite
directions, from unknown what in deep deeper deepest space. It was
early in the 1980s. Your eyes and ears and...

Well, one can't have, or one doesn't need any theory until something

Its stars,and other matter that is being moved faster and faster by getting to close to black holes gravity.Keep in mind these objects are accelerating in and they too are gaining more weight(gravity force) All that enters the event horizon has now reached the structure inside a black hole.The event horizen is constantly enlarging because there is no inner space.Bert
