  It has long been known that the C-14 calibration curve, which relates the
known age of tree rings to their apparent C-14 ages, includes a number of
"wiggles" which clearly are not experimental errors or other random effects. A
reasonable interpretation of these wiggles is that they indicate that the Sun's
fusion "furnace" is pulsating, perhaps for reasons similar to that of the
Cepheid variables, albeit under a very different regime of pressure and
temperature. If this speculation is correct, we are seeing the heartbeat of the
Sun-the C-14 calibration curve is the Sun's "neutrino-cardiogram." Elevated
neutrino flux during a relatively brief period would have two effects: (1) a
surge in C-14 fraction in the atmosphere, which would make biological samples
that were alive during the surge appear to be "too young" (2) depletion of C-14
in the biotic matter already dead at the time of the surge; this is a
consequence of the recently discovered Jenkins-Fischbach effect, which is an
observed correlation between nuclear decay rates and solar activity or
Earth-Sun distance.
  In addition, the precise value at any given time of the "half-life" of any
unstable isotope-including C-14-must now be considered in doubt, since the
Jenkins-Fischbach effect implies that we may no longer view the decay rate of
an isotope as intrinsically governed and therefore a constant of Nature.
