The soul, according to an asinine chain email destined to be born from a Christian grandmother in Tucson seizing upon her misunderstanding of this image to promote credulous supernaturalism.

The email will contain animated gifs of waving American flags from 1993, a few animated crying eagles and that spinning wireframe skull just because it was on her "1,001 wacky web animations" CD from Wal Mart.

It will conclude with something like "So let's kick B-Rock "The Islamic Shock" Hussein BinLaden Fartbongo from the Congo back to Kenya where he was born!!!!! Forward if u like and Jesus will grant u 1 wish it worked for a friend of mine but another friend who didn't forward it got cunt cancer GOD BLESS USA AND ARE SOLDIERS"

And then the entire copypasta involving the marine who punches out the atheist soldier because she puts that at the end of every email she sends anyone

Not true.

90% of the atoms in your body are indeed 'stardust', however 90% of the mass of your body isn't actually contained in atoms. Rather, its mass phasing in and out of existence at quantum levels in unstructured forms.

FUN FACT.

Water isnt 66% hydrogen by mass. Oxygen has much greater mass. Its probably something like 20% hydrogen by mass.

Thanks.

If the body is 70% water (I have no idea). Than the human body by mass is at least 7% water. Now we just have to ask. Is the other 30% of greater hydrogen content than the water? Probably. What with all those lipids and hydrocarbons.

Not that I have studied chemistry or anything.

>> No.4722468

I'm pretty sure that Hydrogen is the only natural element in the universe. Hydrogen is fused to form Helium 2, 3 or 4 in the core of a star. Also, even more interesting fact:

99% of the mass of the human body is due to the energy of empty space.

Get fucked, physicists.

There may have been traces of beryllium and boron as well. Nothing near the concentrations we see now of course.

not sure about boron.

big bang beryllium would decay as not stable isotope

Just because it decayed doesn't mean it wasn't there. And both known isotopes of boron are stable.

When my atheist great grandfather died the priest held a speech about the cycle of matter throughout the universe.

Long story short, he finished up by saying "Earth to earth, stardust to stardust".

Which, coincidentally, would merely be "dust that didn't become a star".

Because stars are made from space dust. Just a whole fucking load of it.

>> No.4722587

>>4722577
plenty of isotopes of boron are unstable. the "known" ones (derp) are obviously the stable ones.

>Just because it decayed doesn't mean it wasn't there
and you have a weird idea of the burden of proof. and we are discussing the currently extant elements.

The question was what elements were produced, not which ones are still around. Theory predicts that Be was formed in trace quantities. This being the same theory that explains the H/He ratio of the early universe so feel free to argue with 50 years of cosmology.

There are plenty of know isotopes for other elements that are unstable so derp to you. No unstable isotopes have ever been encountered for boron. Of course 40B is unstable. The same could be said for 5H or 270N but no one has ever encountered them so they are not considered.

Rephrase. No unstable natural isotopes for boron have been encountered. More to the point, the boron that would have formed during the big bang is stable.

of course not. you are redefining things in a tautologous, self serving and irrelevant way.
>More to the point, the boron that would have formed during the big bang is stable
citation needed

boron synth during big bang is hypothetical, and there's absolutely no reason to believe that if any was formed it was 10B or 11B.

much more likely is that excess boron and beryllium levels were created by fission (NOT fusion) from cosmic rays in the younger universe
