Now this is interesting, regardless of what is found, this could throw things for a loop depending on how large the variation is. I figured this probably deserved a place here rather then in the news section.

The sun might be emitting a previously unknown particle that is meddling with the decay rates of matter. Or, at the very least, we are seeing some new physics.By Ian O'Neill

Share Print Font: +-When probing the deepest reaches of the Cosmos or magnifying our understanding of the quantum world, a whole host of mysteries present themselves. This is to be expected when pushing our knowledge of the Universe to the limit.

But what if a well-known — and apparently constant — characteristic of matter starts behaving mysteriously?

This is exactly what has been noticed in recent years; the decay rates of radioactive elements are changing. This is especially mysterious as we are talking about elements with "constant" decay rates — these values aren't supposed to change, school textbooks teach us this from an early age.

This is the conclusion that researchers from Stanford and Purdue University have arrived at, but the only explanation they have is even weirder than the phenomenon itself: the sun might be emitting a previously unknown particle that is meddling with the decay rates of matter. Or, at the very least, we are seeing some new physics.

Many fields of science depend on measuring constant decay rates. For example, to accurately date ancient artifacts, archaeologists measure the quantity of carbon-14 found inside organic samples at dig sites. This is a technique known as carbon dating.

Carbon-14 has a very defined half-life of 5730 years, i.e., it takes 5730 years for half of a sample of carbon-14 to radioactively decay into stable nitrogen-14. Through spectroscopic analysis of the ancient organic sample, by finding out what proportion of carbon-14 remains, we can accurately calculate how old it is.

But as you can see, carbon dating makes one huge assumption: radioactive decay rates remain constant and always have been constant. If this new finding is proven to be correct, even if the impact is small, it will throw the science community into a spin.

Interestingly, researchers at Purdue first noticed something awry when they were using radioactive samples for random number generation. Each decay event occurs randomly (hence the white noise you'd hear from a Geiger counter), so radioactive samples provide a non-biased random number generator.

However, when they compared their measurements with other scientists' work, the values of the published decay rates were not the same. In fact, after further research they found that not only were they not constant, but they'd vary with the seasons. Decay rates would slightly decrease during the summer and increase during the winter.

Experimental error and environmental conditions have all been ruled out — the decay rates are changing throughout the year in a predictable pattern. And there seems to be only one answer.

As the Earth is closer to the sun during the winter months in the Northern Hemisphere (our planet's orbit is slightly eccentric, or elongated), could the sun be influencing decay rates?

In another moment of weirdness, Purdue nuclear engineer Jere Jenkins noticed an inexplicable drop in the decay rate of manganese-54 when he was testing it one night in 2006. It so happened that this drop occurred just over a day before a large flare erupted on the sun.

Did the sun somehow "communicate" with the manganese-54 sample? If it did, something from the sun would have had to travel through the Earth (as the sample was on the far side of our planet from the sun at the time) unhindered.

The sun link was made even stronger when Peter Sturrock, Stanford professor emeritus of applied physics, suggested that the Purdue scientists look for other recurring patterns in decay rates. As an expert of the inner workings of the sun, Sturrock had a hunch that solar neutrinos might hold the key to this mystery.

Sure enough, the researchers noticed the decay rates vary repeatedly every 33 days — a period of time that matches the rotational period of the core of the sun. The solar core is the source of solar neutrinos.

It may all sound rather circumstantial, but these threads of evidence appear to lead to a common source of the radioactive decay rate variation. But there's a huge problem with speculation that solar neutrinos could impact decay rates on Earth: neutrinos aren't supposed to work like that.

Neutrinos, born from the nuclear processes in the core of the sun, are ghostly particles. They can literally pass through the Earth unhindered as they so weakly interacting. How could such a quantum welterweight have any measurable impact on radioactive samples in the lab?

In short, nobody knows.

If neutrinos are the culprits, it means we are falling terribly short of understanding the true nature of these subatomic particles. But if (and this is a big if) neutrinos aren't to blame, is the sun generating an as-yet to be discovered particle?

If either case is true, we'll have to go back and re-write those textbooks.

this is a VERY interesting subject. bruce cathie talks about this in his books on harmonics. it seems to be somehow related to the variance in the speed of light(bye bye einstein) and its relation to gravity. other forum member with a better mathematic background like clay and vianova could probably do a much better job of discussing this than i can. would love to hear from them on this. my brother Cheers
I dont think it has to do with the speed of light, because if light was slowing down due to gavity, the clocks should slow down just as much and hence there wouldnt be a change. as to what this could be, I have no idea, but there are a couple simple tests that can be done to figure this out.

I wouldn't worry about carbon dating to anything in the last couple thousand years.
You need to be close in most cases, not on the money.
Also when you read this below
you see that an average ...decay variant .... may not affect the dating unless it is extremely old

Now this gets very interesting.

just over a day before
a large flare erupted on the sun.


Now that to me adds to electric universe modeling.
The sun is reacting to a large stimuli and as such the electric event could be solar system wide
as the energy builds up.
The CME or flare event could also be a reaction just between Earth and the sun.
It could be a comet.
It could be something coming through the heliosphere from way out beyond beyond...
Often SOHO has burps and farts and drops data or images get anomalies
just before big flares and CMEs.

One example is comet Bradfield.
Just before the images dropped for 19 hours the last couple
were showing a wild brightening of the entire field of vision ... then ...poof...

And when external electrical influences disturb solar energy
perhaps this 33 day cycle will have variation and the solar neutrinos
are released in massive amounts by external electric stimuli of the sun?
