Audor Modulation: An Open Question on Biological Sensitivity to the Relativistic Time Dilation Factor

This document poses a research question: is there any sensitivity of biological dynamics to the relativistic time dilation factor dτ /dt that cannot be reduced to the known physiological effects of gravity and velocity? The provisional term “Audor Modulation” is proposed to designate a hypothetical modulation of the rates of biological processes by the relativistic factor. The document does not present experimental evidence for this modulation. On the contrary, it analyzes why the experiments available with current technology cannot isolate the relativistic signal from biological noise and gravitational confounders. The conclusion is that the hypothesis is, today, experimentally inaccessible, and the conditions that would be required to make it falsifiable are discussed.
