Something in flares , whether it is particle based or some unknown mechanism , influences radioactive decay rates.<quoted text>
You would think the gravitational force would, too, meaning the field it resided in.
I thought the nucleus had a lot to do with gravity per modern physics.
In fact it is a adjustment to rates that had to be made.
The reason is beyond the scope of science atm, but poly most likely wrote the reason ,(particle bombardment). Other than that it can't really be called random or caused. As the causes are rather probabilistic than deterministic. Only deterministic that flares do cause, but this cause and any other is at frequencies that are probabilistic and beyond the scope of determination.
