    I'm afraid this makes no sense whatever.
    The word "chronology" has a Greek root khronos=time. Chronology cannot have a "duration", that's just silly.
    Besides, it is impossible to give give a definition of duration without first invoking time - "it lasted 10 minutes", say. The word makes no sense otherwise.
    Then you finally flip - how can chronology have a "speed"? That's plain silly

    Now you know the torment we have to endure when he drivels on about cell biology or biochemistry.

    I used the common definition of "chronology" in context of duration and the emergence of time.
    Related fields[edit]
    https://en.wikipedia.org/wiki/Chronology

    Where does this not have anything to do with the measurement and recording of emergent time as a result of duration of a chronology (as compared to speed)?

    Seems to me you are slowly being left standing alone in your torment ......

    Time and Speed exists, but not in the manner you think.
    In science something "exists" as soon as the definition fit to the observation.
    If it is persistent, you can share your definition and all scientist can aprove it by observing the same.

    Perhaps you mean : Is there some undefined underlying phenomena that is the cause that all phenomena do not appear at once ?

    No.
    Mind that an observer can be anything. Without anything time does nor exist.

    It is the smallest possible representation of a value. Without values nothing exists.

    No, it is the upper limit where quantum theory become accurate and newtonian theory become obsolete.

    You just confirmed my posit.
    Quanta is a unit of value. There is something of value lower than quanta?
    What measurable unit of value lies lower than quantum?
    What happens below the Planck length?
    History
    https://en.wikipedia.org/wiki/Planck_length

    I believe that Planck's "fundamental natural units for Planck length, Planck mass, Planck time and Planck energy" are described as "quanta", no?

    Planck units

    Well I subscribe to "Causal Dynamical Triangulation" (CDT), where spacetime is a fractal.

    You forget something.
    What do the world looks like for a bat ?

    ....No, forget the bat.
    What do the world looks like for an atom ?

    That depends on the value of the atom......

    Yes, an atom is something we know from our point of view (as a Man).

    Now, there is no limit in the lenght by itself, there is a limit for who is talking about a length.
    This is an informational limit...
    And yes this is a very usefull property in a quantum world !

    The physician limit is the plancks length, but the reality limit is... limitless.
    You can use your equations using "the mathematical infinitesimal" without ... limitation.
    The objects are not moving in the world "using steps".

    Some works about the subject (Laurent Nottale), in french :

    No, the atom as observed by any relational other value. Man is just another value, albeit complex.

    p.s. are you a opponent of "a universe from nothing"?

    Yes, physical impossibility in a spatial environment. Except for the pre-BB singularity physical things cannot occupy the same space at the same moment.

    Hence the emergent phenomenon of chronological spatial ordering between relational values via mathematical physical functions and the resulting duration of events, measured as units of time.

    Try to understand the observational chain.
    Take this seriously in account.
    Here we are.

    It depend if boson or not...

    There you are.
    You are stuck in the subjective human observational mode. Try to think objectively.

    Yes, it's all about values being processed via constant mathematical functions.
    But "ground state" does not imply same "spacetime coordinate".
