WAG Trash (from Galactic distribution of heavy elements)

The center of galaxies, and along the spiral arms, have more heavy elements than the outer and less dense regions because there are more giant stars packed closer together near the center of the galaxy that go supernova and scatter their heavy elements around.  Earth is in the galactic habitable zone because it is far enough away from the center of the galaxy with the deadly radiation but still close enough to populated regions to get enough heavy elements from supernovas.

That is so very True our SMBH in the milky Way Sgr A does have much Iron "Blue part" around it a Iron Nebula about 5 by 5 ly of it on cross section.

Yep. Nothing in there about an "iron nebula" (whatever that means) or even "blue". 

But it does (not surprisingly) confirm the presence of iron (and other elements).

Look at the picture, that is what Astronomers have to do, do you see the huge nebula or cloud of iron gas? "X-Ray lines""The Blue purple" not "Red purple"

I see an image showing where Xrays are emitted from.

Nothing to do with iron; almost any element will emit xrays if it's hot enough.

Citation needed. The fact there there is some iron (and other elements) present does not make it a cloud of "iron gas".

A nebula (Latin for "cloud" or "fog";^[2] pl. nebulae, nebulæ, or nebulas) is an interstellar cloud of dust, hydrogen, helium and other ionized gases. Originally, nebula was a name for any diffuse astronomical object

They complain that you used words "iron" and "gas".. not that you used word "nebula"..

Iron to become gas.. wow.. it must be really high temperature..

Duh. And please start providing source for your quotes and images. I might have to annoy the moderators by reporting every case where you post unreferenced material.

Still no evidence it is a "cloud of iron gas" (which is not the same as a could containing a number of elements including some iron).

Not in stellar terms.

The iron in the sun is a vapour.

 

[Vmedvil]

It is near a SMBH of course it is plasma or gas, calculate what the gravity must be near a rotating 31.6 R_☉ SMBH is.

In any case, here is the Newtonian way to calculate that for me being lazy.

F_g = GM₁M₂/R² 

M₁ = M_{mass BH} + (E_{Angular BH}/C²) 

E_angular = (1/2)Iω²

Note convert to meters and kilograms.

M_{mass BH} = (4.31 ± 0.38) × 10⁶M_☉ 

ω = 46 km/s

Oh, so it is a big huge massive ball of solid Iron Right next to a SMBH, okay Strange, I would have never guessed.

Why would you say something as stupid as that?

[Vmedvil]

Oh, where then it is Liquid Iron next to a SMBH, gotcha it cannot be gas remember.

Do you not get the point that the presence of iron does not make it a cloud of iron?

It is like claiming the sun is made of iron because the spectral lines of iron can be seen.

Fine, a "Nebula that is at-least partially Iron or contains some amount of Iron" on the east side which is atleast 5 ly by 5 ly of Iron Spectral lines.

Oh, that's an interesting result. Thanks for letting us know about it.

Where I wanted to fix this its spin is 230 Ghz if you want a more exact angular velocity ω = 2πf , f = 230 Ghz, convert to hertz.

You need to stop wasting other member's time with your lack of rigor in mainstream threads. Almost 20 posts worth of wtf. Pop-sci explanations are usually flawed, and you make matters worse with your strong assertions coupled with weak support. Try asking questions if you don't know something.

If you respond to this modnote complaining in this thread, instead of stepping up your game, I'll be happy to split everything after the first few posts into the Trash. Report this post if you disagree with it.

Since when did a Observation become "Weak Evidence" in Science, fine I will explain every detail.

Which was from this image

NASA Chandra Telescope

exact same image labeled.

What is wrong with you? It is weak evidence for a "cloud of iron" or an "iron nebula".
