    But we don't need to measure durations in order to define zero-duration events.

    It's like saying what's the distance between the first foot and the second foot on a yardstick? We don't need a subatomic ruler.

    The distance is not "very small". It is zero. Exactly.

    I disagree. IMO, time is an emergent property along with the unfolding of the fabric of space, which is not infinitely fast.

    How does that change anything?

    Space is not infinitely long, yet there is still a zero distance.

    I disagree. A quantum event is a definitive change of state and time emerges as a byproduct. Without space there is no time. If Space is not infinitely long then Time is not infinitely short either.

    Can you name me a zero-duration event?

    This is a small time scale which appears to be continuous, but still consists of discrete units.

    On the Greenwich meridian where West meets East, How big is the gap between?
    How wide is a line down the centre of the sun's disk?
    It's zero in both cases I think for the purpose of time keeping (olden days of course).

    That would be an equation ; 24h00 2009-03-11 = 0h00 2009-03-12

    Question is can you have a zero measurement of time?

    That's nicely circular....

    can there ever be zero time or is an interval always greater than zero?
    If a single moment in time equals zero, then we get t 0 + t 0 + t 0 ....... = 14.7 billion years ?

    What is the distance in a quantum change? Distance = Time

    Yep.
    Always dealing with real values, always other than zero. The use of zero is a handy tool, but it does not exist.... out there..... as a causal value.
    What's the result of this mathematical function; {(1 + 0 - 0) x 0}/0 = ??

    Given my long held belief, in numerous post over a range of threads, that TIME does not exist it would, to me, to follow the answer would be YES

    None existence of TIME must mean you cannot have ANY measurement of TIME
    which would include even a zero measurement

    Although the question appears contradictory

    IF you don't TRY to measure time does that count as a zero measurement of TIME?

    After all if you haven't tried you cannot get any measurement ergo that equates to a zero measurement

    Or is it you DO try measure time but find nothing hence you DO have a zero measurement?

    Arguing with myself like Humpty must mean is coffee time

    I agree with you, time itself is not measurable, it is a result of measuring the duration of something in reality. It's completely variable, from 14.7 billion years to a quantum moment (see above). LOL, there just too many numbers for my 3 neuron brain...

    Right, Age is the result (sum total) of an arbitrary measurement of duration, lifetime, half-life (qualified as a probability)
    Ever heard of zero age?
