Dissecting an actual science article

[dad]

Looking at an article in a science news site, I noticed it might be a good example to dissect as to the way they arrive at conclusions.

The article is about Mercury. One example of the way they decide on a date for when molten rock appeared is that they used a furnace on earth to heat rock to see when it would now behave a certain way! They then extrapolate that into the unknown past, to declare a way and time that Mercury got it's rocks melted!!
https://www.sciencedaily.com/releases/2016/06/160627132939.htm

"The team melted the synthetic rocks in a furnace to simulate the point in time when the deposits were lava, and not yet solidified as rock. Then, the researchers dialed the temperature and pressure of the furnace up and down to effectively turn back the clock, simulating the lava's eruption from deep within the planet to the surface, in reverse...

..The experiments indicate that the planet's interior cooled dramatically, over 240 degrees Celsius between 4.2 and 3.7 billion years ago -"

Hilarious!!!

Did we consider creation? What happened when God created the planet? Did anything liquefy or melt? Everything about the so called science claim here shouts religion.

You have failed to show why this should be seen as hilarious.

Exclamation marks do not suffice.

Not an article, a press release;
Science Daily recycled it verbatim from the MIT website (which is fine, it's a PR).

The actual study was published in Earth and Planetary Science Letters.

Here's the abstract:

The MESSENGER spacecraft provided geochemical data for surface rocks on Mercury. In this study, we use the major element composition of these lavas to constrain melting conditions and residual mantle sources on Mercury. We combine modelling and high-temperature (1320–1580 °C), low- to high-pressure (0.1 to 3 GPa) experiments on average compositions for the Northern Volcanic Plains (NVP) and the high-Mg region of the Intercrater Plains and Heavily Cratered Terrains (High-Mg IcP-HCT).

Near-liquidus phase relations show that the S-free NVP and High-Mg IcP-HCT compositions are multiply saturated with forsterite and enstatite at 1450 °C – 1.3 GPa and 1570 °C – 1.7 GPa, respectively. For S-saturated melts (1.5–3 wt.% S), the multiple saturation point (MSP) is shifted to 1380 °C – 0.75 GPa for NVP and 1480 °C – 0.8 GPa for High-Mg IcP-HCT.

To expand our experimental results to the range of surface compositions, we used and calibrated the pMELTS thermodynamic calculator and estimated phase equilibria of ∼5800 compositions from the Mercurian surface and determined the P–T conditions of liquid–forsterite–enstatite MSP (1300–1600 °C; 0.25–1.25 GPa). Surface basalts were produced by 10 to 50% partial melting of variably enriched lherzolitic mantle sources.

The relatively low pressure of the olivine–enstatite–liquid MSP seems most consistent with decompression batch melting and melts being segregated from their residues near the base of Mercury's ancient lithosphere. The average melting degree is lower for the young NVP (0.27±0.04) than for the older IcP-HCT (0.46±0.02), indicating that melt productivity decreased with time. The mantle potential temperature required to form Mercurian lavas and the initial depth of melting also decreased from the older High-Mg IcP-HCT terrane (1650 °C and 360 km) to the younger lavas covering the NVP regions (1410 °C and 160 km).

This evolution supports strong secular cooling of Mercury's mantle between 4.2 and 3.7 Ga and explains why very little magmatic activity occurred after 3.7 Ga.

Hilarious because it is so obviously faith based. Tell us how assuming that things were not created and operated under current physics for untold millions of years is not faith based??

Info from now. Not millions of years ago. The speculations all are faith based.

In this study, we use the major element composition of these lavas to constrain melting conditions and residual mantle sources on Mercury.​

You assume melt conditions were the same!

We combine modelling and high-temperature (1320–1580 °C), low- to high-pressure (0.1 to 3 GPa) experiments on average compositions for the Northern Volcanic Plains (NVP) and the high-Mg region of the Intercrater Plains and Heavily Cratered Terrains (High-Mg IcP-HCT).​

Melt conditions when!?

Near-liquidus phase relations show that the S-free NVP and High-Mg IcP-HCT compositions are multiply saturated with forsterite and enstatite at 1450 °C – 1.3 GPa and 1570 °C – 1.7 GPa, respectively. For S-saturated melts (1.5–3 wt.% S), the multiple saturation point (MSP) is shifted to 1380 °C – 0.75 GPa for NVP and 1480 °C – 0.8 GPa for High-Mg IcP-HCT.

The point is that melt or near melt condition depends on the forces and laws that exist. All you do is assume that things melted under the same laws in imaginary time.

To expand our experimental results to the range of surface compositions, we used and calibrated the pMELTS thermodynamic calculator and estimated phase equilibria of ∼5800 compositions from the Mercurian surface and determined the P–T conditions of liquid–forsterite–enstatite MSP (1300–1600 °C; 0.25–1.25 GPa). Surface basalts were produced by 10 to 50% partial melting of variably enriched lherzolitic mantle sources.

In layman's lingo, here you ADMIT the present state based backward conjecture. Hilarious. What, you thought trying to toss in some big words would add credibility to the sicko religion??

The relatively low pressure of the olivine–enstatite–liquid MSP seems most consistent with decompression batch melting and melts being segregated from their residues near the base of Mercury's ancient lithosphere.

What we seem to have is materials that change into other things. They look at the present state, and see how our laws woulda coulda shoulda changed them. Ho hum.. that ain't science. That is religion!

"Enstatite is a mineral; the magnesium endmember of the pyroxene silicate mineral series enstatite (MgSiO3) - ferrosilite (FeSiO3). The magnesium rich members of the solid solution series are common rock-forming mineralsfound in igneous and metamorphic rocks. The intermediate composition, (Mg,Fe)SiO3, has historically been known as hypersthene, although this name has been formally abandoned and replaced by orthopyroxene. When determined petrographically or chemically the composition is given as relative proportions of enstatite (En) and ferrosilite (Fs) (e.g., En80Fs20)."

https://en.wikipedia.org/wiki/Enstatite

"A solid solution is a solid-state solution of one or more solutes in a solvent. Such a mixture is considered a solution rather than a compound when the crystal structure of the solvent remains unchanged by addition of the solutes, and when the mixture remains in a single homogeneous phase. This often happens when the two elements (generally metals) involved are close together on the periodic table;.."
https://en.wikipedia.org/wiki/Solid_solution

Seems? Ha.

The average melting degree is lower for the young NVP (0.27±0.04) than for the older IcP-HCT (0.46±0.02), indicating that melt productivity decreased with time.

Is means now in the present nature. The issue is not what is but what WAS! Your whole trick is to try to say what IS shows us what WAS!

The mantle potential temperature required to form Mercurian lavas and the initial depth of melting also decreased from the older High-Mg IcP-HCT terrane (1650 °C and 360 km) to the younger lavas covering the NVP regions (1410 °C and 160 km).

In other words it NOW requires certain things to form in this state. Ho hum. Wish they would stop peddling their God insulting little religion!!

This evolution supports strong secular cooling of Mercury's mantle between 4.2 and 3.7 Ga and explains why very little magmatic activity occurred after 3.7 Ga.

By THIS EVOLUTION they of course mean the way things now work. Hilarious.​

Dare to try defending it now!!?

You write faith like it's a dirty thing.

 

[Nithavela]

You're getting an impressive amount of mileage out of your one argument. Too bad it's nonsense.

 

[joshua 1 9]

Did anything liquefy or melt?

The Bible says: "the elements shall melt with fervent heat".

 

[Nithavela]

The Bible says: "the elements shall melt with fervent heat".

Well, that's just the present state bible. Show that the bible said that in the past.

 

[dad]

You're getting an impressive amount of mileage out of your one argument. Too bad it's nonsense.

No. Yours is. Nya nya.
One cannot argue that the so called science garbage is not blind absolute faith only.

 

[dad]

The Bible says: "the elements shall melt with fervent heat".

So in creation maybe some melt occurred too...who knows? Also, in the different state past, the changes in elements including what now appears as melt would not require the laws and forces to do it that they would now require in this state. That's what I'm talkin bout.

 

[dad]

Well, that's just the present state bible. Show that the bible said that in the past.

My thoughts also. But ones supposes that in one week of creation where waters separated from land, and mountains rose, and etc etc...some 'melt' or 'melt like' changes took place. Elementary.

I was thinking today that it is no accident that the earth contains all the chemicals and stuff in a human body. It is probable that THAT'S WHY GOD MADE THE EARTH WITH ALL THOSE THINGS..because He was to make man from it!!! We are not insignificant the earth was made how it was made FOR US!!!! Stars too. Sun also. Moon as well.

We be hot stuff.

When blind faith has no basic in realty and is God opposing insanity, yes it is bad, not good.

I take it you agree then.

Looking at another example of the way of so called science we see this. They looked at the color of green galaxies. Then they try to make that color fall into line with their godless beliefs on how stars formed. They then need to invoke some event that causes it inside their religion. In this case, something is needed to stop the gas flow!! Ha.

"Because stars form from dense gas, a powerful process is needed to rapidly destroy their gas supply and cause such dramatic changes in colour, the research found.
James added: "In a recent study we followed simulated galaxies as they changed colour, and investigated what processes caused them to change.

"We typically find that smaller green galaxies are being violently tossed around by the gravitational pull of a massive neighbour, causing their gas supply to be stripped away.

"Meanwhile, bigger green galaxies may self-destruct as immense explosions triggered by super-massive black holes at their centres can blow dense gas away."

So basically they use sims on earth that take a few days, all based on their religious twaddle to cook up what 'golly gee, just probably must have dunnit'

Hilarious. Kids, flee the lie.

 

[Nithavela]

I take it you agree then.

I take it you don't have a degree in botany.

 

[dad]

I take it you don't have a degree in botany.

Tell us the meaning of the flower then, grasshopper.
