- Decay of radon-222 isn’t the only way lead can be created, just a way
- The U238 that started the chain could pre-date the earth
- Half life is only when half of the sample has decayed, but less than half could have decayed into lead
Lead existed more than 4000 years ago, but that doesn’t prove it was part of Earth that whole time. Most of the planet existed in some form before it coalesced into the planet. 😌
That’s not how half-lives work though
God faked all that to prove our faith.
This is an inherently unwinnable trap. Creationists will ultimately always play the undisprovable “God made it that way” card. Blind faith is a mental illness that’s endemic to humanity and is probably going to get us all killed.
Omfg, my dude. I get your point, everybody does, i mean, look at the sub name… But calling people mentally sick just because they can’t resist our inner cope machanism, aka magical thinking, which was deeveloped and stayed there since before the civilisation, is like calling people with allergies “subhuman”, or people who can’t resist the urge to sleep at night *weak".
Do people with allergies control nations with nuclear stockpiles?
Pretty much everyone has some kind of allergy, so probably.
What’s the antihistamine for religion?
Analytical thinking? Scientific method?
Calling it mental illness isn’t just a stretch it’s just fuckin wrong my dude. I get what you’re saying but bro, that’s just how humans work.
For the vast majority of people, belief in science isn’t fundamentally different than belief in religion. Very few people actually know. The rest of us are taking it on faith that the scientific method is working. Even when it isn’t (that’s a fascinating story, btw, a lot of scientists confirmed findings before it was ultimately debunked.)
Taking things on faith is part of why we work as a species, knowing a thing to be true without ever seeing it is critical to a functioning culture.
The fact that that well has been poisoned with bullshit is a natural consequence.
God made it that way.
Well god must have made you with brain damage.
I don’t have brain damage!
Don’t deny the miracle of life God gave you, he gave you brain damage for a reason! Just because you don’t know his plan doesn’t mean your brain damage doesn’t exist… Have faith.

The Earth was created 10 seconds ago and we all have implanted memories, change my mind.
Heretic. True believers know it was 8 seconds ago.
Blasphemer. It’ll be created tomorrow and this is all part of the memory implant.
Nonesense it will never be created this is just a simulation /s
LastThursdayism
That’s not the gotcha OOP seems to think it is. If the world was magicked into existence by a supreme being 4000 years ago, there’s no reason it couldn’t have been magicked into existence with heavy elements having decayed by an arbitrary amount or Pb by itself. 'Tis the problem with invoking appeals to magic. And anyway a quick look on wiki says that primordial Pb was mostly created by neutron capture of lighter elements, not radioactove decay of heavier ones, so the mere existence of Pb proves wrt the timeline of U decay anuway… but at that point if you’re bringing nucleosynthesis into it, you may as well point to anything higher than lithium or even atoms as a concept as “proof” rather than picking anything as exotic as uranium decay.
The only thing that you can use to convince someone who is dead set the Bible is the only truth is…the Bible. And even then they’ll use gymnastics, but at least they can’t just discard the source of evidence like they will anything else. If they bend over backwards to keep the Bible valid, then you know you’ll waste time trying to debate them.
Being a scientist myself, this argument is not very good. The believer can just say that god created lead as well, and didn’t wait for it to be created by decay. If god can create a universe, why shouldn’t they be able to create some lead?
That’s a whole 'nother rabbit hole, that eventually leads to this:
Can blame it on the devil, or can say it’s just a test by God. Anything from old rocks to fossils to light from distance stars created enroute. Using science to debate someone who doesn’t understand science or thinks it’s all a trick isn’t going to work.
Is this kind of decay the only way that all terrestrial lead was created?
Being born from mother tigers is the only way that terrestrial tigers can be created. Except on Creation Day, according to Creationists. It’s not much of a stretch to say that’s where the Earth’s original stock of lead came from too.
Exactly! In fact, we know that the universe was created in media res so that light photons allegedly streaming to us from thirteen billion light years away in mid transit with the exact amount of red shift it would have from that object retreating away from us due to cosmic inflation, was in fact created by God 2000 in route in the (great) void of space so that it would smack not just into the dot that is Earth, but some dude’s telescope and spectrum analyzer.
In fact, I wasn’t born fifty seven (and some days) years ago. I was born this last Tuesday when the universe was created with everything in motion.
I think this is bad science. Its important to call out bad science to prove that good science exists.
I don’t think all lead is the result of radioactive decay.
You don’t think or you know??
Big difference
I am not claiming to be a professional particle physicist, and I don’t have my high school chemistry textbooks memorized so I can’t quote the exact page where Rapid Neutron Capture creates heavier elements that doesn’t go immediately to radioactive elements first.
Still does not disprove the above decay chain. So religion is still BULLSHIT.
Just because for and Toyota are different companies doesn’t mean they don’t both make cars, can make the same thing multiple ways
You can be right too, I surely don’t know. But when saying things as fact, the way you think something happens means jack shit
Still does not disprove the above decay chain.
I never said the decay chain was wrong, I said it wasn’t the ONLY way lead came into existence.
You are the one stating that. Not the meme. They literally stated just the decay chain time line.
You’re circling back on what I’ve already clarified. I’m done. Have a great day!
Hahaha, someone pointed out your error and ya run away
You called it “bad science”
I call it bad science because the meme is suggesting that that is the ONLY way lead exists, therefore the universe is X years old. Its not the only way lead exists, there is a much shorter way. (still way more than 4000 years old)
Do you have some more reading about this? The wikipedia article doesn’t really touch on it.
Stellar element synthesis is where most elements, iron and below, form. Hydrogen, the most common element, fuses to Helium, Lithium. There are more cycles to stars burning elements, Carbon-Nitrogren-Oxygen Cycle, and a bunch of other stuff, all the way up to Iron. After Iron, nuclear fusion can no longer sustain the star, and it collapses into a neutron star (or any other intermediary ranging from hypothetical quark stars to black holes).
On collapse, you get a supernova. Supernova and other high energy events (called Gamma Ray Bursts, usually attributed to Supernova anyway) explode in a shower of neutrinos and gamma rays. These neutrinos rarely interact with matter since they have no charge, but they still contain a lot of energy, traveling near the speed of light. Gamma rays are the highest energy photons. Anything either particle interacts with will change it.
The collision of the gamma rays burst and nuetrinos with interstellar matter creates the remainder of the elements, much in a similar way we do on earth to create the synthetic elements (like plutonium).
Any isotope can be created this way. Isotopes that are unstable then decay until they become something stable - Uranium -> Lead.
The universe is so old that enough of these elements were able to gather by gravity, forming the relatively tiny deposits we can find on our planet.
The assumption is that the only way lead can exist is via a series of radioactive decay. It is a way. It is generally created in stars by a much more direct process, not through radioactive decay.
Is there an emperic difference (like the isotope number or whatever) between lead created through radioactive decay and lead created directly in a star?
So the meme is incomplete, but the general point still stands from what I can tell, right? Stars take orders of magnitude longer than 4k years to create lead as well, and there is no way of lead being created that could happen in 4k years, unless you start getting into “God made the universe look old” territory?
Not really, the original point was to prove the earth isn’t 4000 years old. Even if this were the only way lead could be created I’m assuming some portion of the decay could take place in space and then be part of the earth’s formation.
Stars take orders of magnitude longer than 4k years to create lead as well, and there is no way of lead being created that could happen in 4k years, unless you start getting into “God made the universe look old” territory?
Thats correct, but the meme is written as a scientific explanation and its is wrong/incomplete. To correct it, go with what you said, not with what the meme says.
I mean, it’s created at a cosmic rate in the right sized star.
You’d need to back up and start talking about the big bang and star formation, and at that point lead isn’t really part of the argument. Most elements exist as a result of stars smashing atoms as per my understanding.

In a single star the heaviest element you can make is Iron.
To get anything heavier than Iron, which Lead is, you need your first start to blow up making iron, and the stuff left behind to eventually form a bigger star, then that star needs to blow up (where you’ll get some gold, lead and a few other slightly heavier elements. Then the remaining parts of the star need to form a neutron star. You then need that neutron star to find and eventually crash into another neutron star, and thats where you get the really heavy elements like uranium.
So does that imply that Lead has existed in the universe strictly longer than Uranium? Is the meme entirely backwards?
If you want a layman approach then this Youtube video about where gold comes from is pretty good. You can skip most of the first half about the culture of gold. The second half of the video is the creation part.
If you want a technical approach then you want to talk about Rapid Neutron Capture and GRB. You’ll find that kind of talk here. Warning: When you start digging deep into scientific explanations you discover that there’s more we don’t know. As the article ends with the idea that our current working theory of r-process doesn’t happen often enough to explain how much gold we have so there’s likely at least one other way gold is created in the universe. Welcome to cutting edge science!
I had a creationist professor who had a whole bunch of bullshit specifically intended to “debunk” aging using Polonium half-lives, etc…
You’ll never “disprove” it for them, because they don’t want it disproven. They’ll just find the relevant page on Answers in Genesis/Ken Ham’s website written by someone with a Ph.D. from Pensacola Christian College and consider it done. They’re not in it to actually find the truth. It’s not a good-faith discussion/debate.
Fortunately when they go find some page in AiG, you can just go point at the corresponding entry here: https://www.talkorigins.org/indexcc/list.html
Been a while since I’ve seen that resource. Old webpages are refreshing sometimes.
You might be interested in the community I cross-posted it to then, if you’re not already in it: !oldweb@lemmy.ml
Neat. I’ve ran across a few things that tie to the Small Web, but this is even more eclectic.
In what backwoods podunk shithole did you have a creationist “professor?” What were they even ostensibly teaching?
I had a “Creationism vs evolution” class because I did one semester at a religious college before realizing I wasn’t religious. It was about what’d you’d expect, and no, the credit didn’t transfer to a real college
I’ve seen anecdotal stories of geologists who claimed they were creationists. The brain is an amazing thing.
Isn’t it the other way around? Creationists claiming to be geologists?
I suppose, but the point is they do a job that requires them be knowledgeable of the science, and yet can compartmentalize things to do that but also have beliefs that run very much against what they observe in reality. Hell, geology was a science born from creationists trying to find evidence of the Flood, who then chose to go the path that the data took them, not the Bible.

Is this a real thing (outside of the US)?
It seems that the en article has a bit of an agenda in that regard. You might want to check other versions.
Maybe reality is a bit more nuanced.
It’s 4000 years old…
…and then someThat’s crazy, is this the only source of lead? Like, can’t lead come from somewhere else?
Yeah, this post is not fully correct. The lead nail in the coffin is not that lead exists, it’s that we find it in certain mineral matrixes that don’t form with lead.
Zircon is the most widely referenced mineral in uranium-lead dating, as the mineral rejects lead during its formation, but will incorporate uranium. So when we find zircon with lead in it, it means that the uranium has decayed and turned into lead while being stuck there, and the percentage of uranium to lead in a sample lets us determine its time of formation.
Neat
I’m fairly certain this is leaving out important details. I believe it decays into a unique form of lead with a different number of either protons or neutrons. The actual numbers I could not tell you as I’m remembering this from high school.
It’s a different isotope, so different number of neutrons. If the proton number would be different, it would be another element altogether, since the proton number defines what element it is.
I was in a Discord call and we were talking about theology and one guy used this argument against creationism. The Christian girl in the call said if Adam spawned in as a fully grown adult then God can create pre-aged uranium too.
Which ends up leading up to Last Thursdayism. Weird to believe in a deity that just enjoys fucking with you, but to each their own.
“Mind” I see no evidence to support the existence of one.
