Earth's Moon is Rare Oddball

In an image released by the European Space Agency, the moon is photographed by the Rosetta spacecraft as it passes earth on Nov. 13, 2007.The European Space Agency's Rosetta spacecraft is the first mission designed to orbit and land on a comet. The mission consists of an orbiter and a lander, called Philae. The spacecraft carries 11 science experiments to complete the most detailed study of a comet ever attempted. Scientists hope that Rosetta will unlock the mysteries of how the Solar System evolved. (AP Photo/European Space Agency)

There is reasonable evidence to indicate the Moon did not come into existence through a collision with the Earth!

[irishtenor]

I think it ia an amazing bunch of balony.

[Southack]

Not a collision...

We got our Moon via a capture.

[muawiyah]

There was no Moon. Then a Mars sized planet smacked Earth. The residue tossed into orbit coalesced into the Moon. The other planet merged with Earth.

Could 'splain some of the Super Plumes under the Super Volcanos.

[Southack]

A collision should have some Earth material on the Moon, and some Moon material on Earth.

We see neither in amounts consistent with a collision.

Thus, we got our Moon via a capture.

I’ve never heard of a planet being referred to as a “vagrant”. Isn’t the PC term “homeless”?

“Orbit Challenged”

Genesis 1:14-19

14And God said, Let there be lights in the firmament of the heaven to divide the day from the night; and let them be for signs, and for seasons, and for days, and years:

 15And let them be for lights in the firmament of the heaven to give light upon the earth: and it was so.

 16And God made two great lights; the greater light to rule the day, and the lesser light to rule the night: he made the stars also.

 17And God set them in the firmament of the heaven to give light upon the earth,

 18And to rule over the day and over the night, and to divide the light from the darkness: and God saw that it was good.

 19And the evening and the morning were the fourth day.

Good post Norm.

I believe the capture vs collision jury is still out.

[muawiyah]

What? Earth has been most of it's top most layers of light materials ever since the collision. That's why we have exposed ocean basins filled with basalt and continents of lighter weight limestone floating on top of it.

The Moon, on the other hand, is composed mostly of the same lightweight material that makes up the continents.

That was the clue to the analysis that resulted in a conclusion that Earth's former surface debris from a collision went into the creation of the Moon.

[muawiyah]

CORRECTION: "Earth has been MISSING most of it's top ...."

[Southack]

Basalt is just leftover lava. Lava flows on the seabed constantly.

Moon rocks are commonly called KREEPS because they contain Potassium (K) elements and Rare Earth Elements (REE) and Phosporus (P) not found in almost all rocks and mantle/crust of the Earth. Ditto for regolith. It’s on the Moon, not on the Earth.

Same again for Lunar norite, plagioclase, and pyroxene. Not exactly something you’d typically find on Earth (above or below our surface).

[RightWhale]

The moon is made of materials that would have been part of the crust of earth. The Pacific Ocean is the site of the borrow pit.

[Southack]

Where do we find norite on Earth?

[RightWhale]

It was all sucked into the moon.

[Southack]

Why would it all have been in the point of impact on Earth in the first place?

[RightWhale]

Not only that but there was a third body. The third body missed earth but not by much. We don’t know the composition of the third body, but it contained all those disconcerting lunar materials.

[muawiyah]

That's just from the surface where there's a vast amount of debris that's been brought in by meteors and comets.

The true composition of the Moon is known through inferential evaluation of it's size and density.

There are many things the Moon cannot be ~ e.g. a chunk of iron.

[SunkenCiv]

nuts, I didn’t notice that the other one was newer, and didn’t see this one before, so I posted a bunch of stuff.
