Physical implications of a fundamental period of time2021.10.22 12:36 - Katarzyna Kuźniar
If time is described by a fundamental process rather than a coordinate, it interacts with any physical system that evolves in time. This talk will introduce the resulting dynamics and show that it is consistent with observations provided the fundamental period T is sufficiently small. Using the current accuracy of atomic clocks, an upper bound of T<10^(-33)s is obtained, which is five orders of magnitude below distance measurements at high-energy accelerators. A fundamental period of time could also have additional implications for lab experiments or cosmological observations.
