Please provide any supporting evidence of this hypothesis. I never put forward any hypothesis. I merely asked two questions. They studied a minimal effect on short life isotopes, but what was the effect on long life isotopes? And would historical changes to the magnetic field also have an effect on decay rates considering these rates are affected by solar flares, and the magnetic fields protects us from solar radiation? If you have no clear answers to both those questions then you cannot be confident in the time frames you suggest, they are mere theoretical timeframes based on the old fashioned idea that decay rates are constant.

The fact that independent radiometric testing using different isotopes consistently gives similar age estimates is sufficient reason for confidence. The Purdue study (which has not been reproduced, to my knowledge), indicated a fluctuation of perhaps 0.1% in decay rates - obviously insufficient to significantly alter radiometric dating techniques.

Great, you have supplied some interesting pieces of work, but what you are lacking is any sort of evidence that these all occurred within the last 6000 years.

There is no sufficient evidence to the contrary. Science is based on evidence, not hypothesis unsupported by evidence. You are not facing the fact that the measured changes were for short-life isotopes. What is the Purdue effect on long life isotopes? You should be curious about this, because it can put the entire concept of radiometric dating into jeopardy. You refer to date consensus, I agree in some cases there is consensus and therefore radiometric dating is a reasonable measurement of RELATIVE timescales. But no-one actually knows how the Purdue effect, affects long-life istotopes so the actual dates are completely in doubt. In addition if a sudden slight increase of solar radiation can SLOW decay, what effect will a permanent blockage of much solar radiation have during times of increased magnetic field strength? May I suggest a sure-fire method on how to face these questions? Insist you are correct with no evidence to support your position, and put your head-in-the-sand. It's working for you so far In the meantime radiometric dating is completely in doubt. Uncertain territory. Link to comment Share on other sites More sharing options...

There is no evidence indicating it is in doubt. If you choose to disagree with the evidence, it is a matter of faith, not science. It is unreasonable to scientifically disagree without a reason to do so. It is important to recognize that a belief in Young Earth Creation is due to your faith, not due to contradictory scientific evidence. Link to comment Share on other sites More sharing options...

Let us agree to disagree, the Purdue effect was minor on short-life isotopes, we don't know it's effect on long-life isotopes, so the Purdue effect puts great doubt on the dependability of long-life isotopes until the effect is measured. And magnetic fields have to be taken into account, because the Purdue effect is based on changes to the penetration of solar radiation, and magnetic fields have a strong influence on the penetration of solar radiation.
