Webpendent of the M-clock function, this mechanism was dubbed a Ca-clock (8). Additional studies have shown that the pacemaker cell is actually a coupled-clock system because both M- and Ca- clocks are functionally coupled by numerous voltage-, time-, and Ca-dependent mechanisms (9,10). In addition to aforementioned WebJun 19, 2024 · diuno/iStock/Getty Images. The tick of the Universe. A new theory proposes that time is a fundamental property of the Universe governed by an oscillator that interacts with all matter and energy. A trio of theorists has modeled time as a universal quantum oscillator and found an upper bound of 1 0 − 3 3 seconds for the oscillator’s period.
