For many years a scientific controversy has been brewing far from the spotlight of mainstream media. How constant are physical constants? For decades the scientific consensus has been that “true constants”, such as the speed of light and the gravitational force, remain unchanged over time. But in recent years more and more evidence has challenged this assumption. A telling example is now posed by observed changes in supposedly constant radioactive decay rates in relation to solar flares.
A post by Dan Stober, a physics professor at Standford, goes into some more details about the findings here.
