There's a lot of extra 'science' there that has yet to be vetted beyond the original explanation of supernova.

Not buying it at this point.

Don't see why Plutonium is on the chart with a colour, while other not-naturally-occurring-on-present-day-earth elements aren't. If you're trying to explain the origins of elements like Plutonium that have since decayed away to nothing, why not include other super-heavy unstable elements, plus Technetium (Tc 43) and other unstable non-occurring ones?

Plutonium and all others are naturally occurring elements my friend. But, Plutoniums half life is so short that one does not find it in nature because every bit of it created in that particular supernova that seeded our planet has decayed away to duck shit. :lol:

Don't know about the half life of the others: You look it up, you're the one who asked the stupid fucking question. Expect a report by tomorrow. :De_Bunk:

You don't seem to have disagreed with me :? I said why is Plutonium coloured in when other decayed-away elements aren't - and then you said exactly the same thing about Plutonium while implying that what I said was wrong. :?

Plutonium occurs in nature (from uranium decay, in very minute amounts)

This would be Pu-239

But Pu-244 with an 80 million year half life was found in pitch blend in 1971, the hypothesis is it has existed since the beginning of earth

Pu does exist naturally on earth, but in very very small amounts

So everybody is wrong in some way

Sorry, my mistake. :oops:

Plutonium is formed all the time by uranium, naturally

In very small amounts

The graphic is wrong

Hydrogen and Helium--Big Bang.

Everything else--Supernova.
