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

The Weeners on the article makes it all worth the click.

I sure hope this result doesn't push any scientists off the edge.

What will become of all the bi-polar people? Can't we just replicate it?

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

Computer. Lithium 7. Hot.

In related news, territorial pissings are on the rise.

Maybe all those space-faring civilizations really need a lot of LiPo batteries?

Obviously, a super advanced alien race billions of years ago mined most of the universe's lithium to make batteries. When supplies ran low and they could no longer build enough Priuses and smartphones, their civilization utterly collapsed leaving an empty universe and slowly replenishing lithium reserves for species yet to be.

Let this be a warning to us.

I saw lithium 7 when they opened for Alice Cooper in '77. Didn't the drummer OD and the lead sing join a cult or something. I heard a rumor they were going to get together to do Live Aid but that never happened.

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.

I'm sure someone's thought of this before, but is there something like the triple-alpha carbon resonance at work that preferentially removes Li7 in various processes?

Why does it matter? It's not like we've discovered everything, so how could we possibly know? Maybe space elevator, you know? Right? I mean it's obvious.

I could write a script that makes more meaningful responses out of random words. I won't, but I could.

No, you couldn't.

"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.

It fascinates me the amount of mental gymnastics a supposedly scientific and rational person has to go through to believe we know enough physics to know about how atoms behave, but when that behavior says "no space fantasies", all of a sudden we don't know anything, so anything can happen.

Still too complex for your tiny mind to grasp?

Go watch some Star Trek and hump the screen. Then go make a render of a space elevator or some other fairy tale.

I doubt it, too. But TFA uses those words. Hence, my snark. It's like they felt the need to inject drama.

Science "journalists"- or, more likely, their editors- do tend toward hyperbole and bombast when a much more interesting (and readable) article would involve more information and less hype.

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.

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?

it's copy that's search engine optimized, too.

they get us on both ends.

Well, thank God the abundance of Lithium is in keeping with Big Bang predictions!

I looked at an article on nucleosynthesis and there are three mentions of Lithium: 1) mostly created in the Big Bang when temperatures dropped below 2 trillion Kelvin; 2) destroyed in stars; and 3) created by cosmic ray spallation. I don't know what that is. Sounds a bit naughty. May have something to do with the rain of cosmic ray particles through the universe.

The solution is obvious.

Blame it on the rain.

And then set fire to it!

More likely used the lithium for fusion power ;)
