Chronon

This article describes chronons in physics. For chronons in the database theory, please also look under Chronon (database) .

Chronons (derived from the Greek chronos , time) are hypothetical elementary particles of time.

description

In physics, chronons have so far only been assumed to be quantum time . Similar to the quanta, which represent the smallest unit of energy, chronons are supposed to represent the smallest unit on the time level of certain particles. The size of the unit for electrons is usually given as 2 × 10 ⁻²³ seconds. Through these "time quanta" some inconsistencies in quantum physics could be eliminated. The idea for this comes from a model by Piero Caldirola (1914–1984).

In current research, the proposal of chronons hardly plays a role. On the one hand, it makes perfect sense to divide the time into quantum-like parts - this might make coherent quantum gravity possible. On the other hand, the current extent of the chronon is too large to be able to depict the smallest absolute measure of time: The much smaller interval of the Planck time (10 ⁻⁴³ seconds) would in any case speak against the current assumption of the interval defined so far, because the size is considerably below that of the Chronon.
