| Time is continual and stroboscopic, not continuous. So are numbers:

| But you cannot build a clock out of the whole universe because it will
| not tick. And you cannot build a clock out of sub-quantum scale
| structures because all the dynamics will appear instantaneous, i,e,
| individual clock ticks will appear as one.
|
| What the clock's mechanisms include has no bearing on whether they will
| tick at their scale; they already tick everywhere.
|
| Lets say that Planck is right. There is a fundamental chunk of time.
| How do we get from one chunk to the next ? If the transition is smooth,
| then it might as well be considered continuous. But Planck creates a
| universe which is a little like the old time movies, existence occurs
| frame by frame somehow.
|
| Well, you have this fundamental chunk of time which is very, very
| short. What's it made of ? Must be continuous, but that's a paradox,
| because you already have the smallest possible piece of it.
|
| If the chunks are all there are, it doesn't matter how smooth they are
| with respect to abstract chunks--because the abstract chunks don't
| exist.

| There is more than one dimension to time--at the same time. What time do
| you see the moon in say 1.5 light seconds distant from Earth? Mars, 200+
| light seconds from Earth? What time is the moon in? Plus what time over your
| clock time you see it as being the time for it? What time Mars over your
| clock time you see it as being the time for it when you look at your clock
| and look at it (Mars) in the distance?
|
| There will be two moons in time. Two of Mars. One relative to you here on
| Earth, one real and not relative to you here on Earth. Since the moon orbits
| the Earth continuously it will not even be precisely where you see it to be
| in space from here on Earth. It will be ever so slightly in advance in both
| space and time of your placement of it. The separation between where you see
| Mars to be in space and time and where Mars really is in space and time will
| be much greater. Mars has a relative placement in both space and time, and
| it has a real placement in both space and time different from the relative.
| The first is visible and detected from here on Earth. The second might as
| well be a blackhole or dark matter leading in advance of the first for all
| the detecting you will ever do of it from here on Earth. Also you will never
| travel to the first (the relative to Earth). You will always travel to the
| second (the real). Then there will be two of you also in both space and
| time, the relative to Earth and the real in distant place out there.
| Discontinuity in space and in time. Relative space and time is not real
| space and time. The relative to Earth 'you' will always be detected from
| Earth to be slightly younger than the real 'you' going about whatever
| business on either the moon or Mars. If you are walking a path on either the
| moon or Mars the relative to Earth 'you' will be detected from Earth to be
| somewhere--some distance--behind 'you' on the path never to catch up to
| you--relative to the Earth.
|
| If you stepped through a stargate and took one milli-second (real) to step
| out of it on Mars, the relative to Earth 'you' would be detected from Earth
| to take not one milli-second to do the job but to take 200+ seconds to do
| that stepping out on Mars from stepping in on Earth. Regarding Alpha
| Centauri, a one milli-second jump through some stargate (say real) would be
| detected from Earth to have taken more than four years to accomplish for the
| relative to Earth 'you'. Despite that four years, no passage of time, to
| mean no aging, between the person who stepped into the stargate here and the
| person who steps out at the other end would be detected here. There would be
| a minimum of a four year separation in both space and time between the
| relative to Earth 'you' and the real 'you' in the area of Alpha Centauri.
| Discontinuity in space and in time. Relative space and time is not real
| space and time. In this slightly possible exampling, the milli-second
| transit was the real time of transit, the four years plus transit time
| detected from the Earth was transit time relative solely to the Earth.
|
| Had the traveler at any time before the four years plus lapsed stepped
| back through the stargate and returned to the Earth a milli-second after
| entering, that traveler could be the one to detect himself stepping out of
| the stargate at the other end and sometime later stepping back into to
| return to the Earth. That particular representation of himself would never
| exit the stargate at this end of it...or exit it anywhere else in the
| Universe either.
|
| There is more than one dimension to time.

Idiot!

Androcles.
