Where is the proof about these magic numbers? Checkmate atheist. /s

All math is a lib lie! Just look at those blasphemous arabic numerals!

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.

But the half life of polonium 210 is just 138 days. other is a few days. radium 226 is 1602 years. Why couldn't the earth have started with a lot of radium 226? Checkmate round earthers.

Could have started with lead directly. Why go the extra mile.

Is decay the only way to get lead? I mean if uranium gets synthesized can't lead get made as well?

[–] Fermion@feddit.nl 5 points 8 months ago* (last edited 8 months ago) (1 children)

Radioactive decay is not the only way to make lead, and lead is produced in much greater abundance than uranium.

The part that's missing in the post is in looking specifically at uranium deposits and making assumptions about the initial composition of the deposits, since the crystalline structure excludes lead when the crystals form. So if you detect lead contained within zircon, it is assumed to be the product of radioactive decay.

We obviously live in a matrix/simulated world, and it can't be older than 50 years, because before that, computers didn't exist. Checkmate christians.
