Radiometric Dating: An immutable proof of old Earth.

[essentialsaltes]

Nice knowledge. But I fail to see how would that related to the decay constant.

Because nuclear decay, like nuclear fusion, is related to the nuclear force constants. They are nuclear processes. Now we know the constants are constant, therefore radiometric dating is valid over timescales of billions of years.

Clutching at straws again. Plus it does not really matter. We knew that the Earth was at least hundreds upon hundreds of millions of years old before radiometric dating. All that radiometric dating does is to give a solid number to what earlier was a rather crude estimate.

I don't see how would anyone know that.
A few millions of years would about be right.

Non-radiometric methods can confirm the entire range, such as helioseismic dating, which confirms the sun's age at 4.6 billion years.

How does that one work?

How does the decay constant relate to nuclear fusion? It is new to me.

Interesting article on the history of dating the earth.

That is because you have never studied geology. Geologists knew that the earth was hundreds upon hundreds of millions of years old before radiometric dating came along.

You obviously studied. So how do they know?

Quite a few different ways. By measuring rates of erosion, rates of depositions. Sometimes all that is involved is counting the annual layers in a strata. For example the Green River formation took over 6 million years to deposit, and that is only one formation out of 100's:

The answer is not simple. But the explanation is.

Can you project the time needed when we try to fill the oceanic basin on the same rate?

If you know the volume of the basin, and the rate the basin is being filled, then yes, of course.

 

[Papias]

How does that one work?

Helioseismic dating works by measuring the attenuation of vibrations in the sun, and magnetostratigraphy works by measuring the residual magnetism of rocks.

The upshot is that we've shown you the non-radiometric methods that confirm the radiometric methods, and hence the accepted geochronology of the earth.

So why do I have to ask you again if you agree that radiometric dating is confirmed?

C'mon Juvi, we are just asking for a straight answer. Do you or do you not agree with the accepted geochronologic history of the earth?

How do they come up with 6 million years? Counting 6 million layers of varves?
How about other formations that have no varves?
How do you get hundreds and hundreds of millions of years?

 

[juvenissun]

If you know the volume of the basin, and the rate the basin is being filled, then yes, of course.

That is the problem. It is theoretically possible. But practically impossible.
Radiometric dating could have the same problem.

How could that tell us a very long period of time? I think it would have the same problem as the radiometric dating method.

Right, they can count the layers. Other methods are used for other deposits. Then there is the time necessary to erode some deposits before more sediments were lain down over them. It is a very complex question. I could give you links so that you could begin to learn for yourself, but I am again not going to spoon feed you everything. You have a computer, You have search engines that you can use. Just make sure that you go to reliable sources.

 

[Subduction Zone]

That is the problem. It is theoretically possible. But practically impossible.
Radiometric dating could have the same problem.

And you are grasping at straws again. If you want to claim there is a rate change the burden of proof is upon you. Since all of the evidence out there supports no rate change there is no need to claim one.

 

[juvenissun]

Right, they can count the layers.

Did anyone count 6 million layers of varies?

 

[Subduction Zone]

Did anyone count 6 million layers of varies?

Not one person. Why do you think that is necessary?

It is not reasonable to keep grasping at straws.

 

[juvenissun]

If not, then why do you say 6 million years on the Green River Fm ?

 

[46AND2]

It doesn't. That's why I said it is like filling a 5 gallon bucket with a known flow rate. We know how much radioactive byproduct the mineral had initially, we know how fast the byproduct accumulates, and we have tests to determine whether anything affected that accumulation.

 

[Subduction Zone]

If not, then why do you say 6 million years on the Green River Fm ?

I asked you as question, why didn't you answer it?

Try to think for yourself. How would they know that there are 6 million years of varves in the Green River formation?

You are being obstinate and unreasonable. Those are not supposed to be Christian traits.
