Quantum Apostrophe: Why does it matter? It's not like we've discovered everything, so how could we possibly know?

Oh, and I also asked the question here because I'm sure there's a Fark astrophysicist who might know more about farking Li-7 nucleosythesis than I do and might be kind enough to answer my query. Would you happen to be an astrophysicist? Or is that verboten because knowing about stars means someone might want to build a spaceship?

Quantum Apostrophe: "We haven't discovered everything about physics" is the usual Space Nutter rebuttal to the fact that we DO know a hell of a lot about physics.

C'mon, man, get your head out of your ass long enough to calm the fark down. Was I saying anything about space elevators or generation ships or anything else? No. I was saying that maybe there's a resonance with Li-7 synthesis that we might not know about. And why would we not know about it? Well, maybe it's because we don't live on a star and we never thought to look for it. If you can't sit down and watch nucleosynthesis you might miss something non-obvious. The triple-alpha resonance with carbon-12 was obvious because there was so much more carbon and oxygen than the theory predicted.

Good Lord, you get tiresome with your gorram space nutter axe-grinding. When you keep from frothing you're generally a pleasant Fark conversationalist.

xanadian: Bothering? Unsettling? Yeah, lack of lithium 7. OH THE HUMANITY!!!

I'm assuming you're just being snarky, but I'll give a straight response:

I doubt many astrophysicists are bothered or unsettled. The results good scientists live for is not, "Ha! Exactly as my theory predicted!" Good scientists live for the result that elicits, ""Hmmmm. That's not what I thought would happen. Interesting."

The "problem" with the reported dearth of Li7 is that it doesn't match the amount predicted by the Standard Model. This means either that we're not looking in the right places, not asking the right questions, or the Standard Model needs to be updated/revised/replaced. It could mean all of the above, as well. That's very cool. Hunting for either the missing Lithium or the reason it's missing is going to be interesting, and we'll probably get some neat science out of it- however it turns out.

Pffff. Everyone knows that the Federation removed the lithium to power their space fleet.
