Before this subject deteriorates into what trial lawyers and politicians excel at (twisting words to obscure the truth), consider what happens if time does not exist. Velocity is distance moved per unit of time, or distance is velocity times time. If time does not exist, then nothing moves. Reproduction becomes impossible. Even thought becomes impossible because neurons fire depending on the pulse rate at synapses. Not to mention communication and other things that are frequency sensitive, including light and radiant heat. And then there's the matter of Earth rotating in several ways. Since all of these things do exist, time exists. It is what goes on inside the brains of quantum physicists that leads them to make rash statements about things they cannot measure. As I recall, the derivation of the Planck length seemed suspect. -------------------------------------- But does time actually does exist in an absolute sense? There are intervals between events, that we refer to as "time" or the "passage of time", and we choose to allocate a unit to this, the "second", just as we choose to allocate units to distance and mass. Distance and mass, however, are a bit more user friendly, in that generally there is at least the possibility that a given distance or mass will remain obligingly the same for long enough to enable a repeat measurement, albeit within certain tolerances. This doesn't apply to time, nor to anything else once time becomes involved, which in itself, of course, makes the above statement extremely suspect:-) With time, it's those intervals between events that we seek to measure with ever increasing precision, and great fun it is too:-), but however "repetitive" given events are the "same" event never occurs twice and neither does the same interval. This may all seem boringly obvious but, since "time" depends for it's existence on these patterns of events and the intervals between them, the question as to whether time itself really exists as a quantity may turn out to be not quite so trivial after all. regards Nigel GM8PZR _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
