Yeah, this is broken because all lead did not have to come from polonium, that's how half-lives work.

It's still 100% bullshit in every way, someone just needs to have chatgpt4 sort out the current mass fraction to explain why, I'm way too lazy to argue against insanity.

Real question: Is the decay of uranium the only natural way to produce lead? If so TIL.

[-] Nougat@fedia.io 38 points 2 days ago

Iron is the heaviest element capable of being created inside stars, via fusion. Once iron is fused, the star begins to rapidly collapse.

Elements heavier than iron (28) are the result of supernova explosions, which produce energies high enough to create these heavier atoms. It is further possible, as described in the image, for very heavy elements to decay into lighter more stable elements, those still being heavier than iron.

Lead is 82.

That's what I learned in school, but there's been some research since suggesting stars produces significant quantities of elements up to lead during their lifetimes, even though it's a net energy loss.

No. Nucleosynthesis of lead within stars generated from supernovae make up the bulk of the existing lead on Earth. Uranium decay does provide some additional lead inventory but would be fairly small in comparison.

But the presence of it in the first place within second generation stars proves that lead is billions of years old.

All young Earth creationist should be exiled to a remote desert island to die

I was a YEC before going to university. I studied geology. After two years, I accepted that evolution happened. After four years, I was an atheist. I went on to get a doctorate, and I have published quite a few papers about rocks that are >2 billion years old.

As a kid, there were literally 0 authority figures in my life that accepted that evolution happened. It was taken as a given that it was ridiculous. My biology teacher skipped the chapter on evolution, saying, “this is controversial.”

Patience, love, and making critical information available gives kids like I was a chance.

Two islands, divide them by sex. If you don't, they will eventually overpopulate and start colonizing places like they've been in the last 1000 years.

I assume someone saying this is a creationist and can just say god created Earth already with the lead in it. Therefore it is a pointless discussion.

Which raises the question of why he would create a planet with the illusion of age and send you to hell for falling for his own trick.

Lol, look at this guy, trying to use science and facts to disprove my fairytale. What a joke!

I'm not even sure how you get to 4000 years old from biblical literalisim.

Edit: going strictly by the biblical account, Adam lived to 930 years, and Noah 950. IIRC, their lives did not overlap. Jesus lived 2000 years ago. A whole bunch of stuff happens in between Noah and Jesus. So even if you're working strictly from the bible, how the hell do you get 4000 years?

You can't. The "Young Earth" people are morons.

Lead 204 is entirely primordial and the other isotopes found on earth would be found at roughly the same concentration were all of the lead on earth primordial. It's the excess ratios of the other isotopes of lead that can be attributed to radioactive decay. That is a substantial proportion of the lead on earth, but to say the "existence of lead" is proof of the age of the earth is entirely incorrect.
