Nickel?

[Capiert]

is extraterrestrial, it(s origin) does NOT come from this world (earth).

Or does it?

 

I suspect nickel is a fusion product

 from the intense heat

 of (some) material

 entering the earth's atmosphere.

 

Keyword: atmosphere.

 

Asteroids are smaller objects

 without a significant atmosphere.

 

The moon's atmosphere is also (probably) insignificant,

 as seen from fotos (dark background, no blue sky, nor clouds).

But dust (from impacts), & impacts into sand can also get hot,

 as something (=material, other than air)

 to rub against (for the friction(al heat production))).

 

Cosmic rays have been reported in the upper earth's atmosphere, (presumably) high speed particles, striking=hitting into the atmosphere, with AtNo element ions high as nickel.

 

I've often wondered why meteorites had so much nickel;

 & the earth (had (next to)) none in its rock(s) (bedstone, e.g. granite) mother earth.

 

Why was nickel an extraterrestrial material?

Did those meteorites travel near a nuclear (fusion) reactor, the sun?

Most of outer space was dark, empty & cold.

Most asteroids did NOT seem to have enough nickel,

 if any at all.

(Space exploration for precious metals seemed like a ridiculous pipe_dream fantasy: like looking for gold in the sahara desert, or at your local beach, or a volcano (would be more profitable, because), it's just NOT there, in plenty.*)

Where then did the meteorites get their nickel

 & iron(!) from?

Observing the mass_defect peaks at iron (AtNo 26),

 I (now) suspect fusion (temperatures)

 are the (major) cause for why (almost) any junk (=material)

 entering earth('s atmosphere),

 if not getting vaporized in the process (hint: =cosmic_ray ions),

 can have nickel & iron (in it).

 

(*So (now) all nasa(like industrial companies, have=)has to do is shoot up boulders (into the sky) (beyond the upper atmosphere),

 & (then) let them fall, (transforming in)to iron_nickel meteorites.

& dig out the crater (later).

That's mighty expensive for a few grams of (man_made) nickel.

Isn't it easier just to dig out the rubble that has naturally landed, instead; which we do?)

Nickel is found in meteorites. That is extraterrestrial. It's also found here on earth.  

It's all a product of fusion — in stars (atmospheric temperatures are way too low for this to be a mechanism). It's just that some of the nickel did not conglomerate on earth while it formed — it did so elsewhere.

Isn't this the (recent) second thread on this subject?

Edit

Yes I thought so

W(hy all) the b(rack)ets?

At the temperatures where nuclear fusion takes place, everything vapourises.

The only way you can get solid nickel is to make it in a star - where gravity will keep it together in spite of being vapour- and then release it into the cosmos when the star explodes. Then wait for gravity to bring the "ashes" together.
