I don't believe you. You observe here where the3re is time. Any movements in stars are seen in our time. Why do you run away from those observations?
Who made that rule?If there weren't time at the star, the photons would never have been produced or traveled to us. What we observe is what time and space did at the star.

Ice Cores.

Oh well, let's do ice instead.
Again isotopes are used in ice cores.

Methods
1. Counting of Annual Layers
2. Pre-determined Ages Used as Markers
3. Radioactive Dating
4. Ice Flow Models

Which has nothing to do with your made up dream world changed-state-past.Ice flow models are no doubt present state based.
Another thing you ignored. Your source is nothing more than an outline, not to mention you are ignoring the context of what is meant by pre determined ages. It doesn't mean that they make up ages.Pre determined ages...very funny.
Radioactive same state past belief based so called dating...and 'annual' layers. Obviously that is present state based, as they look at what a year brings about now.
Bing and a bam and a boom.
Yet when it comes to the subject of so-called global warming - almost everyone then ignores that ice core data and blames the current reoccurring rise, approximately every 125,000 years - less than any in history - on man. But I wasn't aware you could radiocarbon date ice cores. So tell us, during those long periods of extreme cold - versus the tiny little warm spells - would you agree that those layers just might be laid down at a faster rate than we currently observe - one of those tiny little warm spells - and judge everything by? That therefore our concept of the passage of time might indeed be flawed based upon layering rates we observe during those extremely far apart and small warming periods?
We are after all, basing our belief on annual layering rates during one of those tiny little warming periods.
EDIT:
I mean after all, in just 50 years we have observed 260 feet of ice accumulated in Greenland alone. Against claims of how long these layers take to form.
http://en.wikipedia.org/wiki/Glacier_Girl
Since the Greenland ice sheet is approximately 4000 feet thick - just at the actual observed rate - versus theory - it would take less than 1000 years. So once again we find the actual data does not match claims of how long layering takes.

Why don't we study how isotopes actually behave in ice.
"The short-term peaks of d18O in the ice sheets have been ascribed to annual summer/winter layering of snow formed at higher and lower air temperatures. These peaks have been used for dating the glacier ice, assuming that the sample increments of ice cores represent the original mean isotopic composition of precipitation, and that the increments are in a steady-state closed system.
What you presented above is an affirmation that you agree with ice core data. Excellent
Interesting that you would bring that up while completely ignoring that I have a thread on that very topic. I'll check it in a moment to see if you have posted any comments. If not please do so. In the mean time I'll explain the problem with that claim.
Greenland is not gaining ice volume, it is loosing ice volume at an accelerated rate. Your accusation concerns the so called "Lost Squadron" that was forced to land in Greenland during WWII. Where the planes landed was the SE portion of Greenland near the coast where the annual snow fall exceeds 2 meters a year. The 260 feet of ice you claim is well over half snow pack and Firn, not ice. It is also on a very active glacier. The 4000 feet of ice you mention is in the northern area of Greenland where annual snow fall is only a few inches. A comparison of actual ice thickness there with that of lost squadron is extremely fallacious.
Justa, before I respond to your post, I want to ask do you know what "d18O" means. Just curious.
I know what everything I study means, or I wouldn't be discussing it - unlike some.
But so you know - since you don't actually - it is the measure of stable isotopes O18 and O16.
But apparently you like everyone else ignores the diffusion we observe even near the surface of glaciers - let alone at great depths and under great pressures. You fool no one but yourself.

That''s what I hear you "claiming," yet presnt no facts to argue against anything.Really? I would say without a doubt that your claim that the "lost squadron" nullify's ice core chronology demonstrates a total ignorance of the process.
Well, I certainly don't claim to be an expert, however, I do have over 25 years professional experience as a chemist analyzing isotope and ion ratios, an M.S. in Earth Science, with a concentration in paleoclimatology. So yes, I "actually" do know something about the subject.
And I am very familiar with the diffusion rate of the δ18O/16O isotopes, that is why I asked if you knew what they meant; as well as δ Deuterium, which you didn't mention. Contrary to what you are claiming those ratios are a very accurate method of measuring annual layers. What your source, Pitman, an M.D. who has no education in paleoclimatology whatsoever, conveniently, fails to mention is that the stable isotope method, like all dating methods, have their limits. In the case of stable isotope ratios they are very good up 8,500 years, and in many cases for as much as 14,000 years. And the reason those isotopes lend themselves to such accuracy due to fractionation of the heavier isotopes due seasonal temperature difference.
Beyond the stable isotope method and limits numerous other proxy's are available as well. Some include seasonal specific concentrations of Calcium, Nitrate, Sodium, and Sulfate ions, acidity, conductivity, and pollen.
Of course the real kicker is that glaciers once spread across almost all of the continents. But then melting occurred and the continents became mostly ice free. But then we ignore this and ignore all the ice that also must have been on top of Greenland during this period of ice ages and all the ice that must have melted off - and claim we can calculate the age of the ice by layering. Layering data is severely flawed - being that in the past there must have been miles more of ice on Greenland if there was 3 to 4 miles of ice on the Americas. So if your radiometric dating was correct - it would have given even older ages - being that during the time when the glaciers melted off of North America and Europe - it must have melted off of Greenland as well. Leaving what was left only of ancient age. Yet they tell us they can consistently date the ice on Greenland from the present backwards, ignoring their claims of 3 to 4 miles of ice covering the northern latitudes that must also have melted off of Greenland.
Yet we hear nothing of this great gap that must exist during the melting of ice across the hemisphere. Are told of constant layering dates that can be traced consistently backwards.
I'd say that consistent tracing is pure dreaming of what they want to be able to claim - not reality. So are we to believe that during the time of glaciers that spread 3 to 4 miles thick across the northern hemisphere, Greenland was unaffected???? Or that during this time of the melting of 3 to 4 miles of ice - Greenland was again unaffected????
He does know fairie dust though.
I certainly see it right now, that's for sure. Why didn't you address the subject matter of the post and instead opt for an argument of fallacy?
http://en.wikipedia.org/wiki/Ad_hominem
Seems that's all I ever see - not debate on the science - but avoidance on your part. So basically until you decide to respond to the science - you will be ignored. I've no time for children that think attacking the poster instead of the post is scientific.
