The big question with decay-rate dating is the question of whether ANY heavy metals which we find near the Earth’s surface are native to our planet or arrived via impact events. Given the standard idea of our planet having formed from swirling masses of solar material, you’d expect all the heavy metals to be at the center and nowhere near the surface.

It’s good for the scientists, who do know so much, to be occasionally reminded how much they don’t know.
I wonder if this changes the age of stars. I don’t know if it’s a factor. But it seems like this might have consequences for things where the difference from Earth gravity is much more than the difference we have from spring to summer.

Right up until you crack open a human skull without a license, try everything, learn everything, and if you want to do brain surgery, get a license and study up.
Nothing on this thread is difficult to learn, a home-schooler with a little sense would get it after a little study.
Physics is easy. Somebody suggests something, folks figure out a way to measure it. That's the way it goes.
But it's not above your pay-grade. You can do physics. You DO physics, whether you realize it or not.
Own the geekage!

And Im not moving farther away, either. I stick with the normal rotation of the Earth around the Sun for now. With the normal rotation of the earth in it's orbit, you *are* moving closer and farther away from the sun. The earth's orbit is not a circle, it's an ellipse, with one foci essentially at the center of the sun.

Jenkins and co put forward two theories to explain why this might be happening. Okay all you FR physicists, help me out here, s'il vous plaît
I'm really only seeing one theory. Do they run together somehow? Was the second theory just modulated out of existence, perhaps from being engulfed by a scalar field?

it is perfectly believable the neutrino flux from all the nuclear reactions in the sun, slightly influences some sensitive decay rates, and varies with distance. But neutrinos pass through matter without hardly ever interacting with it.

It could certainly have an impact on the accurate determination of red-shift, which could in turn affect theories of cosmological expansion, age of the universe, etc.
Did I mention that "it's Bush's fault"?
To: JasonC
To the level of observable changes in V1 and V2 spacecraft? They have radioisotope power supplies. Rather primitive, I might add... dis-similar metal junction generators?
Not my generation.

No research grants? Even with them, this would be a generally very boring project. Boring is hard work, especially for the likes of most physicists.

The earth's orbit is not a circle, it's an ellipse, with one foci essentially at the center of the sun. True. The Earth is actually about 3 million miles closer to the Sun during northern hemisphere *winter*.

In other words, there appears to be an annual variation in the decay rates of these elements. But if it's caused by something to do with the Sun, then there's no reason to believe that any fundamental properties of the universe are changing.

I can still do colpitts oscillator calcs with triodes. B+ and all of that. But it really was an earlier generation.
And besides, I'm just a cook..... That can program on bare metal.

“But Im not moving closer to the Sun, if thats what youre suggesting.
And Im not moving farther away, either. “
You do know the Earth’s orbit is not a perfect circle, don’t you?

Um, each one has minimal cross section sure, but where do you think they come from and what do you think they cause when then do interact with matter? When you have a hot enough reactor, which is what the sun is, enough get put out for some to interact. And their sig is monkeying with weak force reaction rates.

Me too. I heard they have a new album out.
