Does radiometric dating suggest earth is 4.5 billion years old, or at least 4.5 billion years old?

Answer 1

Impeyan link,

Yes. In fact, several different radiometric methods indicate that the earth is at least 4.5 billion years old. There is also the observation that all isotopes with half lives greater than 80 million years are found on earth, but ones with half lives shorter than this, except for ones that are produced by natural processes, are not found. There is also non-radiometric evidence that the earth is 4.5 billion years old.

Answer 2

No it does not.
Radiometric dating is demonstrably flawed. Volcanic rock from Mt St Helens (just decades old) was dated as millions of years old!

Radiometric dating relies on 3 assumptions:
That the original amount of parent and daughter isotopes are known.
That the decay rate has been constant.
That that neither parent or daughter isotope has entered or left the sample.

Most dating methods indicate the earth is young

Helium in the wrong places
human history too short

Answer 3

The age is 4.6 billion years old plus or minus a few hundred million years. No dating method will give an exact result because the method uses averages of several readings and going back so far there will be errors creaping in. If you answer 4.6 billion for the age you will not be wrong.

Answer 4

At least.

We shown from U238-Pb 206 dating in meteorites and Canadian rocks that its at least 4.55 billion years old. From all the data collected,though, its a good number.

Answer 5

Gore would know!

Answer 6

at least
