Default What is time?



Einstein tells us time is what a clock measures, but clocks measure
units of flow. Clocks are convenient measuring sticks that allow
comparison of motion, change.

If you ask what a yardstick measures, I reply distance and show you
examples of distance, my height, the length of your car, etc.

Mass and energy can be stored and bits can be moved. Can time be
stored? If so in what way?

Consciousness requires comparisons to understand our world. If you
and I want to know how fast we can run, we can run a foot race and
note our comparative movement. I reach 100 meters while you go 80.
Your motion is 80% of mine. Decisions of who to send as a messenger
can use such a ratio to make decisions.

Clocks are so useful we forget they are tools to form comparisons,
ratios, to frame our understanding.

I think "time" is a convenience to provide comparisons, but suggest
there is only space of the now. If there is a recording mechanism
available, nows-past can be recorded and revisited..

What is "Now"? That is a mystery. Our senses deal in electro
magnetic waves and various nuclear forces which more and more seem
less and less substantial.

By the way, the smallest "now" might be Lorentz's distance. If only
he could have developed his transformation without light speed and
made it a ratio. Ratio of smallest distance to smallest energy unit?
Useful ratios such as circumference to density get by without time
units, horse races could be determined by ratios, man needs
comparisons to form understanding. Clocks are handy tools, but is
there a "time" dimension?

Time is the metric of entropy, or in other words, just one damned thing
after another.

Dear Dick:

"Dick" <[Only registered users see links. ]> wrote in message
news:[Only registered users see links. ]...

Odometer.


Can distance be stored?


That is just ego talking. Babies understand the world just fine,
and have no comparisons.


Ignoring stamina, sense of direction, longevity of memory, and
more.


Same can be said for distance. Especially since the meter is
derived from light and a clock.


Please record "here". Remember that here is changing position
wrt the Universe at large at ~300 km/sec.


Chemical storage (such as memory) is not electromagnetic waves,
but stuctured connection.


Don't you mean Planck?


It is a failed attempt at dimensional analysis. Spacetime fails
long before Planck scale.


Circumference and volume (part of density) are derived from time
and c.


Are there three orthogonal space dimensions? Or all four the
result of something deeper... say conservation of momentum and
conservation / net production of entropy?

Yes.

There is only 'continuity' and that 'continuity' means in effect that no
physical 'Time' or 'Spacetime' dimension exists.

SR still exists but is simply change occuring at differing rates.

[Only registered users see links. ]

'Time'' does not slow down because of the velocity of a system...
it is CHANGE that occurs at a slower rate BECAUSE of the longer
trajectory of the elemental particles .......AND what a heresy...
Einstein and NO ONE ELSE back then realized it!

I think clocks are valuable means to be able to compare various forms
of energy flow. However, we have no artifact to call time.

The "damned thing" is "Now". (actually now-past as there is a delay
between our sensors detection and the assemblage of a frame of
consciousness). Our mind re-constructs frames of now-past to give us
the illusion of motion.
