New stuff from my shop...

[erikbojerik]

....not the home shop, but the one at work. Who would have thunk it?

NPR podcast

NPR story

[Rickett Customs]

Amazing.... And all this time I used to think that big round light in the sky at night, led me to the bar.

Cool stuff Erik.

[Georynn]

DANG, Look at the big brain on Erik!!!




I didn't know you were a scientist!!! Thats awesome.
That makes you a big nerd (in a positive way)!!
Congrats!!

[pilotjones]

That is so cool. And I'm very jealous of your job.

[Marcury]

Wow, very cool. Can you make fretboard dots out of them?

Hehehe....besides breaking all sorts of NASA rules and a few laws, they would be so small that you'd never see them. They're about this big --> .

Not only that, but if you consider the cost of the Apollo missions and translate that into a cost-per-bead, I think they'd be very expensive.

A real Clark Kent. Although, I am not sure which one is the Superman job.......since this is TB....I would say luthier is the Superman job.
Congrats on the article and the find. Tre' cool!!!!!!
Peace,
Chris

Pretty cool your voice comes out good too.....t

Yeah but i'll bet they'd sound better than clay dots!!!

Imagine the mid-hump you'd get from moon rocks!

I was reading about that earlier this week.
Very, Very, cool(?)

I understand if you blow off the following questions (especially in a TB forum)
(I read just enough, and watch just enough Discovery Channel to be a pain)

• At impact, could water-containing-material (WCM) have been expelled from Earth into a more segregated path?, a path that might have come into play later in the proto-moon’s formation?

• How “cool” would the proto-moon have to be for that kind of WCM to survive?

• Would it have been possible for that “cooler” proto-moon to incorporate that kind of WCM?

MMMMMMM moon water...

[caveat]
The only "giant impact" of this kind that has ever been observed through a telescope was the 8 (or so) pieces of comet Shoemaker-Levy that crashed into Jupiter a few years ago....not exactly analogous to the supposed moon-forming event for the Earth. So this giant impact theory is exactly that....a theory....but a theory that has been shown to be extremely likely (statistically speaking) during solar system formation....so likely that it is probable that all the inner planets experienced at least one, and probably more than one, before reaching their present masses. The giant impact is also really the only viable theory that can explain the angular momentum of the Earth-Moon system. It has been the subject of some pretty fancy computer simulations. Many of these simulations are very high-quality, but because of CPU limitations they all make simplifying assumptions about some key parts of the physics involved. Having said all that....
[/caveat]

A "cool" giant impact, one which does not completely melt the Moon, is one very likely scenario. All the simulations done to date suggest very high temperatures during and immediately after the impact, but I'm not sure that all the variables have been fleshed out fully (impact direction, angle, velocity, relative impactor masses, etc), and none of these simulations have been done with an atmosphere for the Earth.

One problem with a "cool" giant impact is that the Moon's crust is full of the kinds of minerals (feldspar mainly) that float on a magma ocean, which has long been taken as supporting evidence for a high-energy giant impact. But this doesn't necessarily mean the ENTIRE Moon was once molten.

I'm surprised Jens Ritter hasn't used them for side dot material.

If he hears about this, he will.

Thanks for the reply!
(AND for speaking in "101" terms I could understand).
Didn't realize a "cool" impact could be a possible scenerio.
I was speculating maybe the (survivng) water-containing-material came into to play during a later, cooler phase of a "hot" impact scenario.

Wilser,
That Ritter side dot comment; LOL!!

Ritter will probibly use them on his next bass

Damn.. It would help if I read the entire thred before posting my smark-alek remarks.
