Don't people get banned for this?

Say it kills germs that cause bad breath, and we can market it as LIsterine.

You are assuming all compounds, in water and atmosphere, have remained the same over time.

No I'm not. I just said all of the ELEMENTS are the same age. Compounds form and break up all the time. The ELEMENTS are the same age.

[April Lexington]

All I said was that the ELEMENTS are all the same age. Compounds come and go. The ice core compounds have been stable for a long time. So what? The ELEMENTS that structure the compounds are all the same age. Compounds come and go. Elements are all the same age.

[April Lexington]

Irrelevant! Are you on Earth? Are you 4.2 billion years old?

In a manner, yes. I am made up of compounds structured by elements. The elements are all the same age. The compounds that form me are much newer.

[April Lexington]

This is only a theory. Nobody can prove any of that collapsing star stuff. Only a theory. No proof.

[April Lexington]

Given long enough time many isotopes of rather common elements will decay into OTHER STUFF.

If they can decay into other stuff, then, they are not really elements. What does gold decay into?

[Lancey Howard]

Interesting stuff. Good post.
Along the same line, I will be very interested to see what’s swimming around in Lake Vostok.

[SatinDoll]

Elements can be created, April.

[April Lexington]

They cannot. The exist and maybe they reemerge from stars or whatever. But they exist. If they don’t exist, you and I don’t exist. Think it through... Forget about what the Lefties taught you at the University. Think it through.

Gold (Au) has one stable isotope, 197Au, and 18 radioisotopes with 195Au being the most stable with a half-life of 186 days.

Oh, and then it stops being gold, right?

"These deep microbial communities radically expand our concept of the habitability of the Earth's subsurface and, indeed, our biosphere," said Dr. Sherwood Lollar.

Sherwood, Thomas Gold had you by a couple decades:

The deep, hot biosphere

I hate to rain on the parade but all of the elements were created at the exact same time. They have been forming compounds and breaking up ever since. Everything on Earth is the same initial age. If not... where did the new elements come from (other than the fake and unstable ones created in accelerators)...

I hate to rain on your parade, but water's not an element.

[April Lexington]

I hate to rain on your parade but reading in English is important. Elements are the same age. COMPOUNDS come and go.

[April Lexington]

Apparently, from all of the posts I've received on this subject, math and science skills do not translate into reading skills. I'd be concerned about that if I were a scientist...

[April Lexington]

I hope none of these folks are working on the Space Shuttle “O” Rings this week...
