The sun, at 93 million miles away, appears to be influencing the decay of radioactive elements inside the Earth, researchers say.
Given what we know about radioactivity and solar neutrinos, this should not happen.
Small particles of dust collected together into larger and larger objects – pebbles, rocks, boulders, etc – until there were many planetoids in the Solar System.
These planetoids collided together and eventually enough came together to become Earth-sized.
For example, a problem I have worked on involving the eruption of a volcano at what is now Naples, Italy, occurred 38500 years ago with a plus or minus of 300 years.
So, when the materials are appropriate and one carefully avoids contamination and re setting radiometric clocks can be VERY ACCURATE.
This phenomenon might explain changing rates of radioactive decay scientists observed at two separate labs.
Kieth and Anderson show considerable evidence that the mussels acquired much of their carbon from the limestone of the waters they lived in and from some very old humus as well.While searching for an explanation, the scientists came across other research that noted seasonal variation in these decay rates.Apparently radioactivity is stronger in winter than in summer.How do scientists know Earth is 4.54 billion years old?It’s actually difficult to tell from the surface of the planet alone, since plate tectonics constantly reshape its surface.For example, the element Uranium exists as one of several isotopes, some of which are unstable.
