As one part of the dating technique, they showed peak glaciation in Spain was 5000 years earlier than previously thought.
This technique involves the realization that nearby supernovae and cosmic rays effects rocks here on Earth and can be used as a clock. Amazing!.

Accurate to 30 million years in the past!

I am surprised it works for glaciers.
I wonder if it could be used to date approximately when an ancient man-made indentation made in an ancient artifact, such as that made on some exposed slab of rock carved on the surface of the remnants of a very old building, was made?
When we finally get round to putting robot colonies on the Moon with advanced AI, I guess they (the AIs ) would be able to use this method to help date the layers of dust and rock on the surface of the Moon. With no atmosphere in the way, I guess there should be a much stronger signal left from the high energy cosmic rays making it easier to date using this method up there.
Originally posted by humyIt might be a higher intensity signal but it seems to me it would also have a higher noise content by having billions of readings at the same time. Don't know for sure but that would be my take on it. If there was a constant bombardment by cosmic rays on these rocks for billions of years without a break, I would think the rocks would be saturated with strikes.

Originally posted by sonhouseVery interesting. They kind of calibrate it with carbon 14 I noticed.

Originally posted by joe beyserYeah but for just 40 or 50K years back. I guess it can be projected for a calibration run further into the past though.

It's amazing how so many separate techniques for dating all converge on roughly the same age for the Earth.
Originally posted by sonhouseBut not this one, not by a long shot. Not only are the time scales that it is accurate for a mere fraction of the age of the earth, but there are no surfaces that have been constantly exposed for that long.

Originally posted by twhiteheadOf course, but it is just one of many for different time scales. 3 million years is less than a tenth of a percent of the actual age of Earth but it is still useful for figuring out things like glaciers and such from previous ice ages.

Originally posted by sonhouseNot amazing when you consider that the evilutionists are doing the calibrating and they need long periods of time to make their hypothesis seem plausible.

Originally posted by joe beyserIf he had said that then I would point out that they are not purposely calibrated together but merely agree with each other and, therefore, the most logical conclusion of why they all agree is because they are basically correct else it would be a massive absurd coincidence if, despite them working by several completely different ways, they just all both just happened to agree with each other and all be wrong! (plus, of course, basic physics tells us they should work ) -not that I expect him to agree with logic nor understand logic since he has not once ever done either before for his 'logic' goes something like "HOLY!HOLY!HOLY!" which shows the true extent of his intelligence.
