Jolly,Any rock will glow red when illuminated with red light.
It's a lot of trouble to go to but you could use the red light produced by putting the earth in the way of the sun and letting the atmosphere scatter the blue components of the light away. What would be the point?
"We will need to go there and actually get some to know for sure, " we did.
light has a colour trinity
OK, but I still want to know why you want to go to all that much trouble to check something uncontraversial and obvious.Things look red under red light.
Quotelight has a colour trinity and what might that be?Could that be a reference to the tristimulus values used in colour matching? That is an entirely psychometric concept which describes how we perceive colours. What's that to do with the basics of light? It's just a subjective thing.
I was ignoring that aspect. It's also technically wrong since some people have more than 3 types of photoreceptors and some have fewer.
One experiment that would be interesting is to see if it glows red in the dark, as the moon does during a luna eclipse. Under the similar circumstances the moon rock should do the same surely.
I am challenging your assumption that the Moon glows red because the Earth blocks out the blue light, I argue the Earth blocks out the red too. MY POINT.

Moon and Sun can cause each other to have eclipses
the only time you really see the Moon from Earth full on.
JollyQuoteMoon and Sun can cause each other to have eclipsesNo, the EARTH causes a Lunar eclipse actually.
Quotethe only time you really see the Moon from Earth full on. It's always 'full on' 'cos it's a sphere - not a dinner plate.
"Wait two seconds,"If I wait a bit longer and then look out of the window I will see the sunset, it's red.So I know that the earth's atmosphere removes blue light and lets the red stuff through.Just about everyone on the planet is directly aware of the evidence that suports my point of view.Jolly, on the other hand maintains the oposite point of view. Brave? perhaps? Dumb? Also a possibillity. Scientific? Not by any means.
Incidentally, as Jolly knows perfectly well, the question of how do we know they are moon rocks was debated at pointless length in another thread. The analyses of the rocks indicated that they had been subject to conditions that simply don't exist on earth.
"OK when did I say that Mr chemist? "Here"I am challenging your assumption that the Moon glows red because the Earth blocks out the blue light, I argue the Earth blocks out the red too. MY POINT."You seem to have overlooked the fact that the earth has an atmosphere which selectively blocks blue light.
Rocks from the surface of the moon have isotopes which are rare on Earth. This is because the moon does not have an atmosphere to protect the surface from incoming cosmic rays, which create the isotopes.
Last time I checked the atmospher was part of the earth, but not it seems on Jolly's plannet.
Also when he says "Move on Bored move on,So rather than dragging up points that have already been answered. Why not answer the ones that haven't; Like the main question of this thread:How do we confirm the moon rocks are really from the moon?"I presume he means "move backwards" to this, "Incidentally, as Jolly knows perfectly well, the question of how do we know they are moon rocks was debated at pointless length in another thread. The analyses of the rocks indicated that they had been subject to conditions that simply don't exist on earth."which I posted yesterday.
As for the penetrating matter of "Why Moon rock not Mars rock for example? "Because we went to the moon to get it; we didn't get lost and go to Mars by mistake.
Jolly - do you have a clear idea of what you're trying to achieve in this thread? Would you mind sharing it with us?
It's just attention seeking. Don't get involved.He'll go away if he's not encouraged.
You clearly didn't read what I posted. Did you read JimBob's post?As you say the thread's title is "How can we..."Present tense. How we might have done it in 1950 isn't the point.
Now, we can say these rocks came from the moon because they are like the other rocks from the moon.The only problem with that is if you don't believe that we went to the moon. Well, as you say, we are not doing that discussion again but my memory tells me that you utterly failed to convince anyone about your minority view. To the extent that we are doing it again it's because you brought the conspiracy theory up. The obvious answer is they are moon rocks because they look like moon rocks.Oh, btw,re "A rock from anywhere in the universe, will be subject to conditions that don't exist on the Earth? YES OR NO BORED? " The answer's plainly no. A rock from Blackpool will not have been subject to conditions that don't exist on Earth. Blackpool might not be in your univers, but it's in mine.
So you have run out of anything resembling rational argument then.What we could have done in 1950 does not answer the question "how do we confirm moon rocks are from the moon". It might answer "how could we have confirmed that moon rocks..."but that's a different question.BTW, I haven't been caving in over 20 years but I'd quite like a trip to Peru.
