The History of the Carbon 14 Fraction

cosmic rays hit us at different rates is this like a solar no that's not a solar wind thing do we know yeah why i am confused it's really interesting and there's some cool physics there one is that yes cosmic rays have sort of like seasons they are not totally constant. Where these cosmic rays come from depend on like magnetic fields in the galaxy you know what's going on with the objects that are created them so there's those kinds of effects but we can actually measure that in independent ways because they can look at super ancient trees.
