Why do the diamonds required for this compression need the fancy (and expensive) faceting?
I know it is only an "artistic representation" but if I were one of the researchers involved, I would have told the "artist" about the actual surfaces of the diamonds used.

They don't. Illustrating non faceted diamonds in an artistic way is, however, a bit of a poser. i wish they'd just leave artistic representations out of it in such articles. They serve no purpose.

Metals do not form through any mechanism involving a loss of molecular cohesion

Reread the sentence you yo quoted (emphasis mine):

Its molecules began to separate into single atoms, while the atoms' ELECTRONS began to behave like those of a metal.

A metallic structure is a regular structure. And dissociation from the molecular state gives hydrogen atoms an additional degree in which they can form a symmetric (read: metallic) ordering.

The atoms need to re-configure and combine to form the metallic state, they didn't.

And they never said they did. Do I really have to quote every line of every article on physorg for you or would you start bothering to read them before spamming the comment sections with insanely stupid posts?

From the article:

The team says that the newly found phase is only the beginning of the molecular separation and that still higher pressures are needed to create the pure atomic and metallic state predicted by theory.

I swear to god: if people would start reading what is actually written in the articles instead of imagining some stuff out of thin air half the comments on phys.org would cease to be.

You foolishly chat without any knowledge, even though this knowledge is readily available.
"Made of high gem quality, flawless diamonds, usually with 16 facets. They typically weigh 1/8 to 1/3 carat (25 to 70 mg). "

They found that at pressures equivalent to 3.25 million times that of Earth's atmosphere, hydrogen entered a new solid phase - named phase V - and started to show some interesting and unusual properties. Its molecules began to separate into single atoms, while the atoms' electrons began to behave like those of a metal.

This is a contradictory statement. Metals do not form through any mechanism involving a loss of molecular cohesion unless it's the first step of the phase transition. They never made it past this step.

No it is not. Molecular cohesion is not involved. Molecular dissociation and electron delocalisation, more likely.

A metallic structure is a regular structure.

That is not necessary. For example mercury is a liquid metal. All that is needed is electron delocalisation.

And dissociation from the molecular state gives hydrogen atoms an additional degree in which they can form a symmetric (read: metallic) ordering.

Dissociation is the first step towards delocalisation.

... That is also what they did in the contradictory sentence I quoted.

No contradictions.

An electron in single hydrogen atom "behaving like" an electron in a metal is much different than a metallic hydrogen lattice forming.

You can have a metal without a lattice.

The atoms need to re-configure and combine to form the metallic state, they didn't.

Atoms do not have to "combine to form the metallic state". The protons should be close enough for the conduction band to contain electrons. Note that the temperature is probably high, so that occurs even with a sizeable band gap.

The question keeps coming back.
Why are some obviously unskilled people foolishly criticising research ?
This is not even Cosmology or AGW.
Wait, viko is coming with his Holy Matrix !

(Facepalm) Just when I thought you were learning to think...tsk tsk.

When Hydrogen, in any state, displays mobile electrons, you have an electric or plasma current....not a metal. What exactly is metallic hydrogen supposed to conduct there genius?

The question keeps coming back, do you have the ability to think?

A metal is defined as a condensed matter state with mobile electrons.
The hydrogen is conducting electrons, mainly.
You preposterous fool.

You need to follow your own advice and lose the mainstream bias you display when anyone disagrees or questions a statement from an article.

I have no problem if someone disagrees. I have a problem when they don't bother understanding what the article says. Because you keep disagreeing with things that the article (and my post) don't say. You need to learn to read what is there - not to read what you THINK is there.

They will never form a "metallic" lattice, IMO.

Your opinion is wrong - as theory predicts they will and the experiment already shows first indications that the theory is correct. So unless you have something to base your opinion on besides "I think so"...meh.

Your opinion is wrong

Indeed.

Diamond anvil cells are not rudimentary crushing tools; they are optical tools for scientific measurements. As such, they require higher precision cutting technique than ordinary gems.

Here is a link to a specialised manufacturer. Take the time to read it. It will give you a better appreciation of those instruments: http://www.techno...arch.htm

You preposterous fool.

Hydrogen is composed of the two components of electricity.

Weird. You mean two oppositely charged particles. Let's unveil a secret: a proton and an electron.

When one of those components becomes mobile it is a current.

No. For that it has to move.

By claiming hydrogen becomes metallic through dissociation of of the molecules into atoms with mobile electrons that conducts electrons

I never claim blabbering nonsense.

you are claiming a plasma current is conducting electrical current when they are both forms of an electrical current.

I claim no such nonsense, that is your own specialty.
You are obsessed by plasma's. The topic is not plasma physics.
The topic is condensed matter physics.
You know so much less of physics than you think.

This is the real gut buster. Somehow (and I have no interest in who did it, how, or why it was done)
mainstream astrophysics has convinced it's devout that the rules for density sorting paused when our gas giants were forming and proceeded to place the lightest element in the universe "under" all the heavier ones, jack up the temperature to thousands of degrees due to "pressure" from the heavier elements "above" it, and asked science to prove it's theory correct.

Now I have to explain to 2 of the mindless devout who think this is correct why it isn't using grade school physics.

Your opinion is wrong

No, it's not. The theory is rediculous...clearly.

As a sidebar, I love this site because of the ratings people get just because of who they are engaging in a thread. It's like watching people clap for Kanye West.

Yes you are wrong, but you do not know it.
Mind the difference.

[Now children, lets figure out how the lightest element in the universe exists in bulk at the core of a planet.

Jupiter has a rocky icy core, then a layer of metallic hydrogen, on top of which molecular hydrogen, according to present planetary science.

That you don't understand physics does not imply that there is something wrong with it.

About the author;
"he maintains that satellite measurements of the cosmic microwave background radiation, believed by most astronomers to be an afterglow of the Big Bang, are actually observations of a glow from Earth's oceans. (Yes, presumably satellites millions of miles from Earth and pointed away from it that can see the CMB don't exist.) "

"Earth and pointed away from it that can see the CMB don't exist.) He also maintains that the sun is not a gaseous plasma, but is in fact made of liquid metallic hydrogen. None of his ideas have been accepted by any reputable physics publication."

Did great work on MRI but he is a crank.

Did you happen to know the journal that published this tripe is a joke?

There should be a continuous transition between what is a very hot liquid and a dense plasma.

Let me explain. After all, you are unfamiliar with elementary physics.
A metal contains mobile electrons. Does that imply a current? No.
A current requires a non-zero total electronic momentum in the rest frame of the metal.

bschott since you like having fun over nicknames, is your nick somehow derived from "bullshit"? Letzebuergesch language perhaps ?
Or is this similarity a manifestation of karma, cosmic justice?
There is an indian crank expert on karma that posts here regularly, you should contact him.

Wait your actual name is probably "Bill Schott" or something similar. They must have bullied you in school about this. I am just billschotting you !
