Re: Creationists have been very silent on assumptions
Yeah, I was waiting for some creationist to come along. Especially with K-Ar dating, as one of my old lecturers (in the US they would call them Professors and he got his PhD in some area of Geochronology from Harvard many years ago), has been providing me with information on how he used to do K-Ar dating on some formations of the Barberton Sequence...in the 1980's. Since then he has been getting more accurate dates in his research with other methods.
Those mining companies are not stupid! They still pay him to date those rocks. They say more accurate dates (instead of 3.8 billion +- 50 million years) 3.8 +-20 million years will provide them with more accurate predictions on what will be found underground.
I'm still waiting for some YEC to use YEC methods for exploration and mining... They don't seem to want to put their money where their mouths are.

Re: Creationists have been very silent on assumptions
So, Faith, let's discuss the 'assumptions' you think involved in scientific dating. That's what this threat is about.

Re: Creationists have been very silent on assumptions
ICANT disappeared about those 'assumptions'. ICANT knows that he/she can't defend those claims.
My bet is that ICANT will just carry on spreading the same untruths about the nature of geological dating systems to people not educated in geology (probably 99.9999999999%) of people regardless of the evidence.
I mean in my country only around 3000 living people have had any formal education in geology out of a total population of more than 50 million living people. In a country where the economy is very dependent on mining.

Re: Bump for creationist input
Yet, they still keep on going around those "assumptions" on the CMI website, where people are not allowed to comment without severe restrictions on what evidence is allowed. They don't even allow direct measurements...

As for the "assumptions" scientific dating is based on, I just don't get into dating issues at all if I can help it.
You should try it, Faith. This thread is about those "assumptions" those creationists keep talking about. You do know that there's lots of evidence for those "evolutionist assumptions" . This is the threat to discuss those "assumptions".
ICANT disappeared. Obviously ICANT is not able to handle reality.

Faith writes:
Sure: absolute or "scientific" dating is irrelevant if relative dating is all it takes to find oil or do other practical geological work
I disagree. Relative dating is very, very important in describing the coal deposits I, personally, work on. Remember those exploration and mining companies?

No my goofy idea is that in the far distant past the earth was smaller than it is today. I believe that is also the scientific view as the earth grew bigger over millions of years.
Changing the subject, again?

Re: Bump (again) for creationist input
My favourite one was
quote:
Simply put, atoms typically have an equal number of protons and neutrons, as seen in the image below (left side). An atom becomes radioactive when it has more neutrons than protons, which makes it heavier then it's supposed to be.
This guy is stupid. That's not an ASSUMPTION.

Re: Bump (again) for creationist input
That's right. No point in running DNA tests to determine paternity. We must refer only to eye-witness accounts of penis depositing sperm into vagina.
And not any old sperm. We must have eye-witness accounts of the exact sperm out of millions penetrating and fertilizing the egg...and recreate the same sperm cells doing exactly the same years afterwards in a lab.

That's exactly the opposite of what I've understood from what edge wrote.
In my field, accurate dating is paramount in trying to predict what will be found underground. Modern dating systems work extraordinarily well.
Maybe you, personally, do have a big problem in you trying to find "The Truth (Pty. Ltd)" instead of looking for models providing the best explanations for what is observed (the truth)? Maybe it's because you don't know what scientific methods involve?

Re: Questions
I looked at you first link. A few sentences in it says:
Your source writes:
...The visible universe is static and much smaller than we thought...
Nonsense. We can disregard your link. The Universe is expanding at an accellerating rate.
In the meantime, why do all the major exploration and mining companies I've ever worked with accept radiometric dating as accurate? Are they all stupid?

The first one was economical with the truth. No reason to look at the rest.

Re: Questions
PaulK, the person is trying to address the believers. They will believe whatever he says regardless what is shown in reality.
