So could you just tell me about phosphorus?
I know it's an element on the periodic table.
And did you find it in this asteroid sample?
And what role does it play in sustaining life as we know it?
Okay.
You know, to you, rocks are alive.
That's fine.
Don't worry.
Yeah.
So tell me about pre-solar grains.
There's a lot of research papers on this.
In fact, we have some on display here at the Rose Center for Earth and Sprays.
In fact, they're pre-solar diamonds, I think.
And I think it's kind of cool.
I just don't know its relevance.
It's cool to think of.
Grains that might have predated the formation of the solar system, which gets you even farther back than the four and a half billion years.
So I think that's kind of cool.
But is it just sort of cool to know or does it have other relevance to any of this?
Isn't some of these that you're describing used as fake diamonds on Earth?
