It's an x-ray source.
Big deal.

You Black Hole zombies! Really!

And *where* does gravity come from, Dorothy?
The wicked witch of the East?

Physics FAQ
How does the gravity get out of the black hole?
http://edu-observatory.org/physics-faq/Relativity/BlackHoles/black_gravity.html

First part of the above reads:

"How does the gravity get out of the black hole?
Purely in terms of general relativity, there is no problem here. The
gravity doesn't have to get out of the black hole..snip"

That's as far as I read.
How does gravity "go" anywhere?
And if it is "going", what is it that's "going"?
Gravitons?
Waves?
Has anyone seen any of these?
Is it these that these gentlemen are talking about?
We're not even sure how fast the effects of
gravity travel, given the hypothetical happening of
a planet appearing where there wasn't one before, how
fast would planets X lightyears away take to feel it,
etc., etc.
We essentially know *nothing* about how gravity is produced
by atoms or what it is.
So, when these gentlemen say:
"How does the gravity get out of the black hole?
Purely in terms of general relativity, there is no problem here. The
gravity doesn't have to get out of the black hole, snip ",
They don't have clue number one about what it
is they're trying to get out of that black hole,
or how fast it's coming, or *anything* about it.

All Cyngus is is a big pair of binaries where one is
dying and spiralling in, why does it have to be a BH?

A bit of self education, John, wouldn't hurt you. Why play games?
Why not learn something about black holes?

Multitasking, Sam. Multitasking. Plus, sometimes killing Nazis
outweighs learning about black holes.

Plus there is a really low limit to how much you can learn about black
holes with no background in mathematics or physics.

I have university calculus, physics, and chemistry to 3rd year level.

Wow, all the way to "3rd year level". What the *** does that mean?

Does that mean you flunked out when you got to the 'really hard'
physics like E&M or quantum mechanics?

I have interest in Science since 1962 special interests
Friday science in Grade 7.
I watched when gravity was disproven by galactic
rotation curves.

Oh yes, gravity stopped existing the moment people noticed galaxies
weren't rotating to spec. Did gravity start working again when people
discovered the actual existence of dark matter, or have you not heard
of that yet?

I watched when someone said, "Duh, maybe there's
some kinda dark matter pulling them thar stars around.

I puked.

Touchy.

The stuff you are 'learning' contains
no logic, no common sense- you are told time and
time again: "This sounds really crazy but...........".

Well, guess what.
Physics today with its BHs, DMs, DE.....................
is good old BS.

Apparently you have not heard about how dark matter was verified
recently by weak gravitational lensing. Something is there!

Apparently you have not heard of the *massive* body of data supporting
the existence of black holes - or something with those properties.

Apparently you don't know jack *** about physics. Getting all the way
to "3rd year physics" in the 1960s does not mean you know what is
happening in 2006.


There is no such thing as a
black hole created by gravitational collapse.

You flunked out of university [why only 3rd year, if you didn't?] yet
you think you know more than the physicists. Neat.

The centers of galaxies are there because they
were formed in special conditions and are spacetime vortices
that turn spacetime inside out, changing the virtual
pairs into plasma, which becomes radiating stars.
The radiating stars orbit the vortex until they radiate
all their spin away and fall back in to repeat the process.

Which of course makes less sense than black holes.


What you are 'learning' is disinformation.

Only in your mind.
