  In nematodes, environmental or physiological perturbations alter death's
scaling of time. In human cancer, genetic perturbations alter death's curvature
of time. Those changes in scale and curvature follow the constraining contours
of death's invariant geometry. I show that the constraints arise from a
fundamental extension to the theories of randomness, invariance and scale. A
generalized Gompertz law follows. The constraints imposed by the invariant
Gompertz geometry explain the tendency of perturbations to stretch or bend
death's scaling of time. Variability in death rate arises from a combination of
constraining universal laws and particular biological processes.
