Christian response carbon dating
(See https://answersingenesis.org/geology/radiometric-dating/acceleration-of-radioactivity-shown-in-laboratory/ ) It is theorized that the flood was caused by God speeding the decay rate, causing excess heat inside the earth, triggering volcanism and earthquakes and shifting tectonic plates, which poured steam into the atmosphere, forming the clouds that inundated the world.
The resulting warm ocean and volcanoes caused so much water and dust to enter the atmosphere, that they blocked the sun and triggered an ice age.
The carbon-14 dioxide is utilized by plants in the same way normal carbon dioxide is.
This carbon-14 dioxide then ends up in humans and other animals as it moves up the food chain. Libby introduced the carbon-14 dating method at the University of Chicago.
The half-life of carbon 14 is approximate 5,730 years.
That means if you took one pound of 100 percent carbon-14, in 5,730 years, you would only have half a pound left.
For every one trillion carbon-12 atoms, you will find one carbon-14 atoms.
Some of them must be taken on faith - we have no way to inspect the entire geological and chemical history that a specimen has undergone in order to tell if any assumptions have been violated.
Young earth creationists have challenged several of the assumptions.
2) Over time, as C-14 built up in the atmosphere (via cosmic ray bombardment of atmospheric Nitrogen), things would begin to take on a younger C-14 age.
3) The flood of Noah removed a huge amount of carbon from the biosphere, burying it underground. (See https://org/article/7311 ) 4) Since then, C-14 has recovered and increased.The above story is consistent with the Bible, and accounts for fluctuation in C-14 concentrations in the atmosphere that would then be interpreted as older and younger ages than the true ages.
