#57644 — Moon was produced by head-on collision?

Moon was produced by head-on collision | Astronomy.com
http://www.astronomy.com/news/2016/01/moon-was-produced-by-head-on-collision

The Theia Theory used to talk about a glancing blow between the early 
Earth and a Mars-sized Theia, perhaps at 45 degrees. New data suggests 
that Theia might have actually hit head-on with the Earth. That's 
because the percentage of Oxygen 16/17/18 isotopes between the Earth and 
Moon are nearly identical, indicating that they came from the same source.

My question is, if the isotopic evidence which was used to create the 
Theia Hypothesis in the first place, due to a previously perceived 
difference in isotopic abundances, so now that that isotopic evidence 
has disappeared, why keep the Theia Hypothesis? There were other 
theories prior to that, which were discarded due to the isotopic evidence.

How many of them involved collision-and-mergence of two bodies?  The only variant I am aware of that is significantly different, is gravitational capture, and that took a third body.

Still have an initial Theia...

The truth is...the origin of our solar system is...unknown.



So, how everthing got put together is unknown...including the moon.

Does "unknown" mean "unknowable"?  Is all quest for knowledge ultimately doomed to failure?  Or are you a post-only nay-sayer?

We have brains, and we have data.  Do you mind if we use one, and try and understand Nature, while you fiddle away, Nero?

For those seeking to know the origin of our solar system...all one has
to do is start and end here:

'In the beginning God created the heavens and the earth.'


The above sentence contains all the information one needs to understand
the origin of our
solar system and the universe.


Within this sentence contains the entire knowledge of the origin of the
universe.
'In the beginning God created the heavens and the earth.'

You just need to know how to decode it.


For example, ..."created the heavens and the earth", .. "heavens"
doesn't necessarly mean stars. It could mean
how stars looked before they became stars...without the light.

In other words, the earth and the stars were created at the same time,
they just both weren't formed completely then.

Yeah, that's the hypothesis we usually start off with initially, and 
then we invent new instruments and obtain new observations which lead to 
better hypotheses, and then eventually to some proper theories.

Well, it reads "the heavens and the earth", not 'the heavens and then the earth'.


So, somewhere along the line...your new instruments, your better hypotheses, and proper theories
is off by 5 billion years.

The UCLA press release is at
http://newsroom.ucla.edu/releases/moon-was-produced-by-a-head-on-collision-between-earth-and-a-forming-planet
and the article in _Science_ is at
http://science.sciencemag.org/content/351/6272/493.full

I couldn't find a preprint, but there might be one somewhere.

Specifically, the new data show the isotope ratios (actually a ratio
of differences) is the same within 2 ppm.  A paper last year
http://science.sciencemag.org/content/344/6188/1146

found apparent differences at the 18 ppm level.  The new paper
suggests that was sample selection, i.e., the rocks analyzed earlier
were not characteristic of the whole Moon.

>  indicating that they came from the same source.

If the isotope ratios are identical, _either_ Earth and Theia had
identical ratios to begin with (possible but not very likely) _or_
the present Earth and Moon have identical fractions of Theia
material. That last would require a head-on collision with everything
getting mixed; a glancing collision would put a larger fraction of
Theia material into the Moon.

I'm very much an outsider here, but this looks to me like a highly
technical insider dispute that most of us shouldn't worry about.

The isotope ratios are _at least_ very similar, now seemingly
identical within measurement accuracy.  This tends to support the
Theia hypothesis.  If the Moon formed on its own and was somehow
captured by the Earth, it would be expected to have very different
isotope ratios.

That evidence being the _similarity_ of ratios, which is now stronger
than before.  The argument now seems to be about the details of the
collision, but as I say, I'm an outsider.

For a different hypothesis to be viable, it will have to be
consistent with not only the isotope ratios but also the element
ratios and other evidence.  As with all scientific hypotheses, it
will have to be testable (falsifiable) to receive scientific
consideration.

The Moon capture hypothesis was only one such hypothesis. That one would 
still be excluded by this recent finding.

Other ones that would still be viable are the Fission hypothesis, where 
the Moon was once a part of the Earth, but due to an imbalance it 
pinched itself off of the Earth. This would certainly maintain identical 
isotope levels between the Earth and Moon.

Another one is the Condensation Hypothesis, which suggested that the 
Earth and Moon formed from the same section of the original solar system 
nebula. So basically the two worlds evolved together as a twin planet 
system. This would also pretty much maintain identical isotope levels.

This site even says that if the isotope levels are different, then the 
above theories would be unlikely, but now that the isotope levels are 
similar, those theories come back into play.

The purpose of our moon is to make an ocean on earth.

And the oceans on the moons of Saturn and Jupiter...?

Your supposition is at odds with Biblical text.  I don't suppose that matters to you...

Or should I say...our moon helps in the process of making an ocean on
earth.

Without our moon, we would not have an ocean...it wouldn't even rain.

Now, if you're wondering how our moon got to the vincity of our
earth....that is
an entire different process...that's part of the ball rolling process i
mention elsewhere...

In other words...

it's very simple..

the point
the earth is at
the point the moon is at
from the sun..
and each other
was exactly where
they were meant to be.

it took a 
big bang
to accomplish it.

That which you call
the singularity..
where everything
is stuck together...
and cannot move..
the shape
of the
singularity
was a triangle.

Now, I know for
sure no one here
has ever been told
the singularity
was the shape
of a triangle.

It is very simple
geometry.

If you understand the
shape of the singularity...

then you can understand
the points at which the earth
the sun
the moon
are where they are now.

In other words..

the universe today
is at it is because of
a
triangle.

When the big bang
occured...
the singularity
triangle points
went
in
every 
direction.

In other words...
the reason why the universe
'appears' to have no center is
because of the
triangle singularity.

Everything 'looks' random, even
though everything is in it's place.

In the place...where it's suppose to be.

Everything is in it's place.

Not quite excluded but made a lot less likely since the moon would have 
to have formed in the vicinity of the Earth's orbit to have the right 
isotopic signature. I wonder what the REE signatures look like for 
basaltic lunar material since that would be an independent test.

Odd then that it rains methane rain on Titan. And there is clear 
evidence of previous liquid water on Mars which has no such large moon.

The moon *is* responsible for our more variable oceanic spring and neap 
tides and perhaps indirectly for the evolution of land animals.

Without the moon we might not have lunatics like you!

I was refering to "our moon", not those other...props.


Did you just say " previous liquid water on Mars"???? Oh, you're just
one of those lemming fools.

Your logic is.. without our moon we have  'previous liquid water on
Earth'.


Where would the water come from without our moon? 



The moon existed at the same time as the earth....they are both the same
age.

The moon is what makes it rain.

The clouds are created by the moon.

No moon, no rain clouds.


Right?

Originally from later impacting comets and/or the initial composition of 
the nebula that the Earth condensed from.

Initially it would be far too hot for any liquid water to exist and 
until the planet surface cools so that thermal velocity of water 
molecules drops below the escape velocity of the accreting planet the 
water cannot accumulate. Helium and hydrogen can escape relatively 
easily from our planets atmosphere even today.

Mars only really managed to hold onto CO2. OTOH Titan in the far reaches 
of the solar system had hydrocarbon rain. It seems just about possible 
that so does Pluto but at such a low temperature that nitrogen and/or 
oxygen is in a pseudo liquid slushy phase and has water ice mountains 
floating in it that are as hard as steel.

*WRONG!* Moon howling netkook nutter territory.
"Starmaker" makes Oriel36 look almost sane.
