Aging in a Relativistic Biological Space-Time

Abstract: Here we present a theoretical and mathematical perspective on the process of aging. We extend the concepts of physical space and time to an abstract, mathematically-defined space, which we associate with a concept of “biological space-time” in which biological dynamics may be represented. We hypothesize that biological dynamics, represented as trajectories in biological space-time, may be used to model and study different rates of biological aging. As a consequence of this hypothesis, we show how dilation or c… Show more

“…Studying time-related frailty biomarkers imposes another set of considerations. Maestrini et al (2018) suggest that relativistic corrections of physical time similar to those used in the Einstein relativistic theory resulting from accelerated or decelerated biological dynamics may be used to model the pace of aging. Such theoretical framework places and describes the biological dynamics as trajectories in a biological space-time reference system.…”

“…62 In recent times, the old Newtonian notions of time in biological processes has been replaced with a more complex model that makes allowances for time dilatation and contraction. 63 Some authors suggest that biological aging is a manifestation of the cumulative of repetitions of certain cycles, for example circadian rhythms. Given the sheer number of such cycles occurring within a complex unit such as the midface, we face a reality in which, much like the quantum world, everything is changing all the time.…”

“…Due to time dilatation, at the end of the journey, A and B will no longer be the same age but B will be older than A. It is important to underline that this is possible only if it is assumed that the biological system of A is sensitive to the relativistic effects predicted by GR [8]. If we assume that biological time is in relation to the physical time described by GR, then the experiment can be accomplished.…”
