Geological dating techniques

[pshun2404]

Notice that you never answered this question. Which of the rocks used for dating geologic layers was chilled down to 12 Kelvin during its history? If these rocks were never that cold, then your objections mean nothing.

Notice you said "IF' and we cannot know for sure that any ever were or were not "EVER" cooled to that temperature. But if they are (in this case the rocks where this element is found are igneous where no fossils are found but are used in dating layers above and below in absolute dating). Therefore I did answer your question but you did not like it (pr else could not grasp it).

You have also not shown that any of the isotopes used for dating have that variance at that temperature to begin with.

True, what I have shown is those they tested did show such variance (albeit that was the extreme) and so it is possible others may have some variance under different conditions (but no has tested ALL the possible isotopes).

What Isotopes are used for the dating of actual fossils? Do you know? Clearly NOT c-14 so which ones?

Uranium-235 compared to proportion of Lead-207, it's daughter isotope.
Potassium-40 compared to proportion of Argon-40 is also used.

Since an exceedingly low temperature of 12 Kelvin was brought up, I felt the need to convert that in order to get across how cold that is: -438.07 F, or -261.15 C. This is not a natural temperature on this planet. Unless a fossil somehow ended up in space, then plummeted down to our planet and miraculously remained intact, there's no way a fossil would experience temperatures anywhere near that cold.

Yes, we can. In the past 4 billion years or more the Earth has never gone down to -438 F, or -217 C. There would have been liquid nitrogen on the surface of the Earth. It is ridiculous to think that the Earth got that cold.

True, what I have shown is those they tested did show such variance (albeit that was the extreme) and so it is possible others may have some variance under different conditions (but no has tested ALL the possible isotopes).

That is false. It's like saying that water can freeze at 0 C, so one can then claim that ethanol can freeze at 100 C.

Different isotopes behave differently.

What Isotopes are used for the dating of actual fossils? Do you know? Clearly NOT c-14 so which ones?

Again, you date the geologic layers above and below the fossil to determine the age range during which the fossil was deposited. Why do you think this is an invalid method?

No, you only know what YOU can see with your eyes. You really have no clue about what observation is.

Christians accept more actually. Your observation powers are stunted.

Once again you demonstrate your ignorance. Science has testable models.

Yes they do. Not for anything we are talking about though.

But it did not say that we don't know.

Yes it did. The important bits to the plate tectonic questions have to do with the inner earth.

Once again, you are the one that believes in magic.

The magic genie of great ages (as many as ever may be needed, when more is needed they simply invoke more) may not seem like magic to you. I think there is help available for that.

Projection again.

Wrong again, and this is the sort of answer that makes your ignorance of the sciences so obvious. The theory of evolution has been tested many thousands, if not millions of times. That is why I offered to help you learn what the scientific method is.

Yes it did. The important bits to the plate tectonic questions have to do with the inner earth.

Sorry, quoting out of context again. You are trying to use a false argument. Just because scientists have some unanswered questions does not mean that they have not answered countless questions. You appear to know that you are wrong since one has to know that to quote out of context in the way that you are. Let me give you an example of why you are wrong. The Bible says twelve times "there is no God". I would have to quote out of context to make this claim, but my quotes out of context would be no more dishonest than yours have been.

The magic genie of great ages (as many as ever may be needed, when more is needed they simply invoke more) may not seem like magic to you. I think there is help available for that.

Once again, you believe in magic. Not those that accept reality. Great ages is a fact. But I have heard that to the uneducated simple science will look like magic at times.

You could always learn. There is nothing stopping you from doing so except for your own fear.

Fossils are older than the layers found below them and younger than the layers found above them.

Actually this is the wrong way round; fossils are older than the layers found above them and younger than the layers found below them. However, everything else in your post is correct and informative.

 

[Astrophile]

False. The magic genie of great time is a completely circular concept invoked to explain things science does not know.

Looking at an example of plate tectonics, it is unknown how this works. In all cases, the explanations involve waving the magic wand of great time as needed, to crystallize some explanation.


"-scientists can neither precisely describe nor fully understand the forces, most believe that--"

To put it crudely, denying the reality of plate tectonics because scientists don't fully understand how plate tectonics works is like saying that the fact that we don't know the father of an unmarried woman's child means that she may have become pregnant without having sexual intercourse.

Never once. What is tested is evolution in this age to some degree.

Just because scientists have some unanswered questions does not mean that they have not answered countless questions.

Anyone can answer countless questions who doesn't know. That is actually a bad thing. Better to admit they are real ignoramuses.

The Bible says twelve times "there is no God". I would have to quote out of context to make this claim,

There is a God, but something tells me you don't even know that much.

Great ages is a fact.

Invoking the genie of great ages is what is done. Call it what you like, you were not there nor was anyone else to confirm or deny.

 

[Subduction Zone]

Never once. What is tested is evolution in this age to some degree.

Oh my. You could not be more wrong. I can tell that you do not understand the scientific method at all. Anyone that understand the scientific method can see how it has been tested.

Advice that you should follow. Scientists do not tend to answer questions until they are rather sure of their answers.

There is a God, but something tells me you don't even know that much.

Strangely enough there is no evidence for your God. Do you realize that quoting out of context is not honest? By your previous strategy the Bible claims that there is no god.

Invoking the genie of great ages is what is done. Call it what you like, you were not there nor was anyone else to confirm or deny.

One does not need to be there. Countless crimes are solved without anyone being there. Events leave evidence. Evidence can often be dated. All you have are creationist PRATT's (Points Refuted A Thousand Times). Why not learn a little before you make more embarrassing posts?

We don't need to discuss evolution. How about learning what the scientific method is and what scientific evidence is?

Did someone deny plate tectonics? I think the issue is what makes plates move, not whether they do. Science doesn't understand. Like to pretend you do?

Wrong again. The article that you linked showed how they work. They simply won't say that is the case for sure since they can't directly measure the rate of flow of material in the mantle. They can measure subducting plates going quite deep into the mantle, until they get hot enough so that they flow instead of move via earthquakes.

Not fully understood. How deep is the issue, what makes it happen, - not whether there are zones of subduction. To claim zones of subduction mean that it is understood is wrong.

Another example is the fermi bubbles. (mysterious structures that emanate from the Milky Ways center and extend roughly 20,000 light-years above and below the galactic plane). -NOT understood.
Then there is the recently discovered rectangular galaxy. NOT understood. (The galaxy LEDA 074886 is shaped more or less like a rectangle)

By the way. let's do a fact heck on you. Show the source for plates going deep into the mantle.

This has what to do with ancient geological formations?

How deep is the only question. What makes it happen is pretty obvious.

186 miles deep. In your link it mentions things like

"reveals a high Q and presumably cold region--"
"The models also require that the upper, cold nose of the mantle wedge be isolated from the main flow in the mantle wedge in order to sustain the cold temperatures inferred from the Q tomography. Possibly, sufficient mechanical decoupling occurs--"

Not sure how this helps you? Where the issue was that they had admitted no knowing....we should be seeing something from you that shows they do know.

It is true. You were not there. Comparing forensics with the distant past is apples and oranges.
