Assertion of an "absolute now" from "What is 'spacetime' really"

[Michael Mooney]

Moderation note: the first 92 post of this thread were move from thread “What is ‘spacetime’ really?”, because they concern the assertion that an absolute “now” exists, while the original thread is excessively long, and a more general discussion of spacetime.

 

Essay:

The point is not that "clocks" slow down, but reality slows down.

 

Ummmm.... "Reality slows down"??

Say, just for a moment, that you took a flying leap out of the "relativity paradigm" and landed in what most folks *think* is impossible... a cosmic perspective on "Reality.

(Just for a moment... please... you can go back to relative perspective immediately after this little "thought experiment. But *please* "go with it" for this exercise.)

 

"Seeing" (or even Being!!... a thought experiment, remember!) Cosmos aa a whole... everything everywhere is all happening right now. The speed limit of light only limits what local perspectives can "see," and even the sunlight we see now left the sun over eight minutes ago. So, there is, of course, a time delay in what we can see... the farther away the event/lightsource, the longer the delay.

OK... back to "Reality" with a capital 'R'. Everything everywhere is moving... on all scales from subatomic to universal/cosmic. We all know about these cycles on all scales ('cept maybe the Big Cycle of a possible cyclic cosmos!) Earth spins in "real time*" "one rev a "day" and orbits sun once a "year." Etc., etc... Galaxies spin one rev every so many million "earth years"... etc. (*Real time* in this sense is "absolute* meaning natural cycles that have nothing to do with human (or other intelligent life form) "observation" or the limits of relative perspective.

 

Are you with me so far??

 

So... from this "cosmic perspective" what would be the meaning of your phrase, "Reality slows down?" It would lose its meaning outside the paradigm of relative perspective.

 

So then, what would the concept of gravitational slowing down of time mean? Absolutely nothing! It is just a myopic, relativistic paradigm... as if human perspective and our poor instruments of measurement... (like clocks that slow down under variable gravitational conditions) actually dictate that "Reality slows down!"

 

Is there anyone here who can see the anthropomorphic absurdity of this?

I think not, and I am sorry about that.

 

Now, granted, this was presented as a "thought experiment." But then so was the Minkowski/Einstein/relativity *theory* of "spacetime" and in particular "dilated time."

 

So... the above can be seen as just another thought experiment. It is in fact, the way I have "seen" Reality all my life. ... And It doesn't "slow down" just because our clocks can't keep absolute cosmic time under the stress of various gravitational and other inertial changes "relative to each other."

 

Just a little food for thought to sleep on.

Hope it doesn't give anyone nightmares!:thumbs_up

I think someone is confusing "the existence" of an ontological, universal cosmic time, which is something we assume (yes, there is one of time), and "the rate" of real times in independent Lorentz frames, otherwise known as reality.

[modest]

"Seeing" (or even Being!!... a thought experiment, remember!) Cosmos aa a whole... everything everywhere is all happening right now.

You have to define "right now" in a way that makes it a concept which can be understood and used from one person to another. In other words, you need to define it well enough that somebody could describe a real world situation (including multiple events on moving and accelerating objects) and use your definition to find which events are "right now" or simultaneous with other events. You've been asked to do this multiple times and demonstrated that you are unable to do so. Your cosmic perspective of a universal "right now" is thus undefined.

 

So... the above can be seen as just another thought experiment. It is in fact, the way I have "seen" Reality all my life. ... And It doesn't "slow down" just because our clocks can't keep absolute cosmic time under the stress of various gravitational and other inertial changes "relative to each other."

 

Are you still suggesting that "stress" (or some kind of physical force) slows clocks down mechanically as an explanation for time dilation? Or, are you saying you have no idea why they slow down but you are open to some alternative to the spacetime explanation?

Doctordick:

PS before one can talk about space time one needs a good self consistent definition of both "space" and "time"; something totally lacking in this thread.

 

From post #3:

"If space is actually the emptiness in which all observable phenomena take place, being nothing in and of itself, then the mystery of gravity (how it works) remains a mystery without the assertion that this "fabric" is indeed *something real* as in my reference to "The Emporerer's New Clothes."

 

I went on to define and elaborate on my meaning for "space" literally dozens of times in this thread.

 

From post #5:

"I am asking for answers to the properties of spacetime as an actual medium, *if* "it" is actually more than a juxtaposition of "space" as emptiness and "time" as measured event duration.

(Bold emphasis just added.)

 

Subsequently I practically beat "time" to death with my criticism of its ubiquitous reification.

My "time piece" i've bumped most often is this answer to "What is Time?"

"Two answers to consider simultaneously...

One:

It is the *concept/measure* of event duration, like

A: one rotation of earth (day and standardized divisions thereof... hours, minutes, seconds... nanoseconds)

B: one earth orbit around sun (measured three different ways giving three technically different *spans of time*)

C: the great cycle of the precession of the equinox

D: a complete "bang/crunch" cycle, if my favorite comology is true...

...You get the idea.

Two: Now, the present is always present, not sliced into units of time in the real world/cosmos. As I've said many times, future is not yet real and present and past is not still real and present, and there is no "time" between future and past. Therefore "time" is not a natural reality in the strict ontological sense of what is real.

So, "spans of time", as above are as real as we make them. There is no cosmic counter clicking at every complete earth rotation, year, etc. Yet we can "be on time" to work by common consensus on the convention, time. and we can plug in "time" as a component of velocity and calculate and execute a round trip to the moon.

 

It is also conventional to call "time" the fourth dimension added to the obvious spacial three which describe volume. Then we can avoid having two airplanes at the same coordinates in air-space at the same time. A very useful convention.

But it doesn't expand and contract as an actual entity of any kind... See Two above. "

 

It has become obvious that you don't listen to anything I say, but this is ridiculous.

Also, wherever I disagree with you, you claim that I have not sufficiently "thought things through." (Good grief!)

And when I challenge you to critique my point by point criticisms of relativity vs the parts I acknowledge as valid... twice now since your first potshot, you totally ignore the challenges and just take another sniper shot. This is not constructive dialogue.

 

Btw, Have you even bothered to read the piece on "The Ontology and Cosmology of Non-Euclidean Geometry" which Ive bumped and quoted from many times? It far surpasses your critique presented here in both breadth and depth on the Euclidean vs non_Euclidean issue.

Then there was my link on in-depth ontology. Did you read it? How about my last critical reply to AnssiH.

You just keep shooting from the hip without any response to any of the above.

Very poor aim, doc. And you haven't even located the target.

Wow! Like "define 'is'!

The Present.

What has already happened (regardless of where in the universe) is not now happening.

 

What hasn't happened yet ( again, regardless of where) is not now happening.

 

I've said the above many times in many ways. How could it be made more clear?

 

Since your total reality is within the relativistic frame of reference ("Everything is relative")... and all about the "real world situation (as you see it) (including multiple events on moving and accelerating objects)... you can not even make sense of my repeated references as above.

 

And you challenge:..." use your definition to find which events are "right now" or simultaneous with other events."

 

"It" is "right now" everywhere! The time delay for 'seeing' what happened (past tense) "far, far away" does not change this.

Get it yet?

 

Are you still suggesting that "stress" (or some kind of physical force) slows clocks down mechanically as an explanation for time dilation? Or, are you saying you have no idea why they slow down but you are open to some alternative to the spacetime explanation?

 

I thought we beat this debate to death already. Your insistence that velocity alone can account for differences in clocks' time keeping ignores the changes in inertia that gives the clocks different velocities.

The math tool which supports this confusion is called the "momentary comoving reference frame (MCRF.) The idea is that if you take a series of very fast-lens snapshots of moving objects, the changes in inertia are virtually ignored. So then we say there is virtually no difference in inertia between the two objects (say clocks) with different velocities.

But you thought I was claiming it was just about differences in acceleration at launch (say some years ago) that gave the clocks different velocities. Whatever. They were subjected to different forces (including different G-force at different altitudes in other cases) and so they tick faster or slower relative to each other.

In addition I am also obviously " open to some alternative to the spacetime explanation?"

Actually more like "totally reject the "spacetime explanation."

 

And then you keep saying "Time is what clocks measure*." So when they keep different time, as above you say "time dilates" or slows and speeds up "for one clock" relative to the other. But there is not one 'envelope of time' around one clock and another rate of time in some medium around another!

 

With the same logic* we can say that "Auras are what aurameters measure" or "Ley lines of force are what specially tuned dowsing rods measure."

 

Get my point? Ontologically none of the above establishes the "reality" of time as a dilating (etc.) medium... or "bioplasmic energy" or "ley line earth forces" as "real."

 

Why open the same old can of worms again?

If you want to really consider the 'reality' of time, then ultimately you have to accept that time is "something that evolves" in QM interactions, or something that "started" when the universe did, in relativistic terms.

 

We still have no 'real' idea how to reconcile these two kinds of time; the QM time evolves spontaneously, as if 'created' by what we call a unitary evolution, of a quantum state.

In the universal, ongoing 'continuous' time, there is the conundrum that time also looks like space. In QM these are most definitely not interchangeable.

 

So there is a 'real' universal time which depends on a 'past worldline', and a future. Past and future aren't in the frame in QM, there's just a 'unitary time'; quantum interaction appears to be fundamentally distinct somehow from a universal frame with a relative position (in the L-frame).

 

Interactions between particles can also be 'particles' - the photon is a transfer function for electron momenta, electrons are a 'massive' transfer function for photon momenta - these pictures are equivalent; in GR mass is qualitatively, and quantitatively, bounded and evolves 'in' time, as momentum; the particle space/time boundaries in QM are non-commutative.

 

In that sense, QM forces us to consider two distinct kinds of time and space, since 'we' are embedded in the same generally relativistic frame, though at low speed so time isn't 'stretched' over the universal frame we're in (but it is for 'particles' with a high velocity). We think we have to reconcile these ontologies (or find a solution that places them in the same kind of physically real frame), but maybe we don't...?

Rather than repeating myself over and over, please read or re-read my following most recent comments on time from the previous page... and then, if you will, tell me how specifically you disagree:

Post 670 to Doctordick (my "time piece" re-bumped several times in this thread.)

 

I totally disagree with your opening statement above.

Time is how long it takes things to happen, but since everything is always happening (moving) everywhere, the "time-keeper" determines what event in particular he is timing, then clicks his stopwatch, so to speak at his selected "beginning" and "end" of the event upon which he is focused.

 

Of course,what units of time he uses is arbitrary... usually based on fractions or multiples of our common earth-commensurate cycles, the day or year.

 

Beyond such "time keeping" there is no "time" between "the future" (not yet happened) and "the past" (not still happening.) No "time in between".... always, perpetually, ongoing NOW.

 

Your reference to time starting "when the universe did" is strictly linear thinking and in denial of the possibility of a cyclic universe. Further, where do you think all the matter/energy/plasma in the cosmos came from to "start the universe?" Did it magically appear out of nothingness? Might as well go with religious mythology and believe that "God" pulled the cosmos out of a cosmic Magic Hat!

Ok, but I totally disagree with your disagreement.

You seem to be saying "time is how long time takes", for someone to click a stopwatch. You're defining it in terms of itself.

Of course,what units of time he uses is arbitrary... usually based on fractions or multiples of our common earth-commensurate cycles, the day or year.

Using arbitrary units of time lets a time-keeper keep arbitrarily accurate time...?

Beyond such "time keeping" there is no "time" between "the future" (not yet happened) and "the past" (not still happening.) No "time in between".... always, perpetually, ongoing NOW.

Local time is specific to a local observer. A local observer has a worldline with a past and future, or there is "no time except now"...?

 

Your reference to time starting "when the universe did" is strictly linear thinking and in denial of the possibility of a cyclic universe.

Unless the universe keeps restarting, I suppose that's true (maybe).

Further, where do you think all the matter/energy/plasma in the cosmos came from to "start the universe?"

Matter appeared, when mass did, simple.

Did it magically appear out of nothingness? Might as well go with religious mythology and believe that "God" pulled the cosmos out of a cosmic Magic Hat!

The Higgs field might just be the Magic Hat you mention.

[Michael Mooney]

Boof-head,

This thread is on the ontology of spacetime, and often will focus on the component parts, like "What is time, really?"

My last post replied to your statement:

If you want to really consider the 'reality' of time, then ultimately you have to accept that time is "something that evolves" in QM interactions, or something that "started" when the universe did, in relativistic terms.

 

You claimed the "'reality' of time" as an ultimatum I "have to accept"... that "time is 'something that evolves' as if its ontological status as an entity were already established. Thereby you had already abandon the ontology and asserted your own version the epistemology of "time" as an evolving entity.

 

So I had requested that ... you "tell me how specifically you disagree" with my:

Post 661 p.67 to Pyrotex.

Post 664 to essay and...

Post 670 to Doctordick (my "time piece" re-bumped several times in this thread.)

 

Specifically, " please read or re-read my following most recent comments on time from the previous page... and then, if you will, tell me how specifically you disagree."

 

You refused the request. There might have been "dialogue" but ....

 

Instead you misunderstood my statement:

Time is how long it takes things to happen, but since everything is always happening (moving) everywhere, the "time-keeper" determines what event in particular he is timing, then clicks his stopwatch, so to speak at his selected "beginning" and "end" of the event upon which he is focused.

...

 

And replied:

You seem to be saying "time is how long time takes", for someone to click a stopwatch. You're defining it in terms of itself.

 

I did not say that ""time is how long time takes", for someone to click a stopwatch."

 

Re-read my above statement for what I actually said. repeat: "Time is how long it takes things to happen"...etc. There are no natural "beginnings and endings" to the perpetual movement of all things in the universe. So specific event duration is a function of the focus (on which events) for whatever particular duration... as determined by the guy with the focus and the stopwatch.

This point went completely over your head.

 

Me:

Of course,what units of time he uses is arbitrary... usually based on fractions or multiples of our common earth-commensurate cycles, the day or year.

You:

Using arbitrary units of time lets a time-keeper keep arbitrarily accurate time...?

 

The convention of naming "event duration" requires specific units of duration. In the real world, there are natural cycles, regardless of how we divide them up into fractions (of a day) or multiples of so many years. This obvious point about specifying "how long something takes to happen" was also totally lost on you.

Me:

Beyond such "time keeping" there is no "time" between "the future" (not yet happened) and "the past" (not still happening.) No "time in between".... always, perpetually, ongoing NOW.

 

You assume that time is some "thing" with specific location when you say:

Local time is specific to a local observer. A local observer has a worldline with a past and future, or there is "no time except now"...?

 

On cosmic scale, everything is happening now... always... perpetually.

Locally, "atoms" are buzzing with energy with specific frequencies... allowing us to use them as clocks in some cases. Cesium radioactively degades at a specific rate, for instance... until it is subjected to inertial change... etc. So... so many seconds can be counted out by the rate of cesium degradation... variable as above. Time does not speed up or slow down. Time is not a natural event like cesium degradation is. All "time dilation" theorists miss this point, as "time" is already reified in their minds into an actual changeable medium.

 

Likewise locally, Earth rotates and orbits the sun (Doh!) This is natural "event duration" regardless of how fast or slow our clocks (in different inertial frames) are "ticking." The rate of spin and orbit does not vary with our clocks speeding up and slowing down.

 

Are you beginning to get a feel for what the "ontology of time" examines? You don't seem to have a clue. "Time" is an entity for you, so the ontological question whether or not it is an entity doesn't even occurr to you.

Me:

Further, where do you think all the matter/energy/plasma in the cosmos came from to "start the universe?"

You:

Matter appeared, when mass did, simple.

 

It appears that the question did not even register. Matter/Mass/Energy/Plasma... the "stuff" of which cosmos is made... Where did it come from??

Again:

Did it magically appear out of nothingness? Might as well go with religious mythology and believe that "God" pulled the cosmos out of a cosmic Magic Hat!

You:

The Higgs field might just be the Magic Hat you mention.

 

Do you actually think that dropping the phrase "Higgs field" explains where everything in the universe came from.... as in "someting from nothing?" This is the most elementary level of ontological absurdity. "Ontology 101" starts with the obvious fact that everything in the universe (the real stuff) did not magically appear "out of the Void of Space." It all actually had to always be in existence. None of "it" is created or destroyed. It just constantly changes form.

Seems that this discussion must start in ontological kindergarten and then progress toward more complicated *theories* like the Higgs field.

 

If that is your a-priori assumption... that the Higgs field is the cosmic "Magic Hat", then we left serious science behind before the ground rules of ontology were even established.

Good grief... and good night!

Michael

[Boof-head]

You assume that time is some "thing" with specific location

No, I stated that local time "exists" for an observer. If time isn't some thing, how do you explain your attempts to ontologise it? You have to assume it exists, though, because you have to explain that you observe, and also exist.

"Ontology 101" starts with the obvious fact that everything in the universe (the real stuff) did not magically appear "out of the Void of Space." It all actually had to always be in existence. None of "it" is created or destroyed. It just constantly changes form.

How do you know it didn't magically appear? What evidence can you forward to support your proposition?

Or that it had to "always be in existence"? Isn't matter disappearing from view at the edge of a visible horizon, so it's changing in a way that means it has been 'destroyed' or erased, as far as our future observations are concerned? (Note how your proposition implies a permanent past and future for the entire unchanging universe).

[maddog]

This thread is on the ontology of spacetime, and often will focus on the component parts, like "What is time, really?"

I would expect such. As I have said earlier, there is a distinction between the concept

of time (as we view it) and time itself (if there is an itself per se). The passage of time

is ascribed by people by agreement. We all agree to what value is one second. As a

representation of what we view, we can consider time as an additional coordinate (with

the appropriate conversion factor - c). Time then just becomes another form of space.

This notion is Not an "is", instead a working principle to view the world. In this way

we can label this "spacetime" as "space" and "time" combined. It is the Ontology of

what this represents I think is what you have attempting to get at. I am maybe others

here have been confusing what you were driving at as to "what is [the representation]

'spacetime' really?" Where we differ is you use the "glasses" of Euclidean Geometry to

perceive that Reality, I allow the possibility of a Differential Geometry with some local

Radius of Curvature.

Do you actually think that dropping the phrase "Higgs field" explains where everything in the universe came from.... as in "someting from nothing?" This is the most elementary level of ontological absurdity. "Ontology 101" starts with the obvious fact that everything in the universe (the real stuff) did not magically appear "out of the Void of Space." It all actually had to always be in existence. None of "it" is created or destroyed. It just constantly changes form.

Seems that this discussion must start in ontological kindergarten and then progress toward more complicated *theories* like the Higgs field.

 

If that is your a-priori assumption... that the Higgs field is the cosmic "Magic Hat", then we left serious science behind before the ground rules of ontology were even established.

Your version seems a bit Aristotelian doesn't it ? Actually the notion of "something from

nothing" or Vacuum Fluctuations has strong theoretical grounding and can happen.

The probability is low so as to be inconsequential yet is why you can never attain a

temperature of exact Absolute 0 degrees Kelvin.

 

As for the Higgs Field, I am not sold totally on the idea. I am aware it is part of the

current Standard Model (it took me more that 10 years to warm up to QCD... ... ).

It is not a "Magic Hat", did not come from a Harry Potter novel. It is a sombrero and

is a representation of Symmetry Breaking. I just wonder if some other mechanism is

going on here.

Say, just for a moment, that you took a flying leap out of the "relativity paradigm" and landed in what most folks *think* is impossible... a cosmic perspective on "Reality.

(Just for a moment... please... you can go back to relative perspective immediately after this little "thought experiment. But *please* "go with it" for this exercise.)

"Seeing" (or even Being!!... a thought experiment, remember!) Cosmos aa a whole... everything everywhere is all happening right now. The speed limit of light only limits what local perspectives can "see," and even the sunlight we see now left the sun over eight minutes ago. So, there is, of course, a time delay in what we can see... the farther away the event/lightsource, the longer the delay.

OK... back to "Reality" with a capital 'R'. Everything everywhere is moving... on all scales from subatomic to universal/cosmic.

Galaxies spin one rev every so many million "earth years"... etc. (*Real time* in this sense is "absolute* meaning natural cycles that have nothing to do with human (or other intelligent life form) "observation" or the limits of relative perspective.

Are you with me so far??

Yeah, I am with on this thought problem...

So... from this "cosmic perspective" what would be the meaning of your phrase, "Reality slows down?" It would lose its meaning outside the paradigm of relative perspective.

So then, what would the concept of gravitational slowing down of time mean? Absolutely nothing! It is just a myopic, relativistic paradigm... as if human perspective and our poor instruments of measurement... (like clocks that slow down under variable gravitational conditions) actually dictate that "Reality slows down!"

Is there anyone here who can see the anthropomorphic absurdity of this?

You have now gone and concluded the effect you created in your "thought problem".

You can't go and create world in your head and conclude the effect as "proof", "justifcation" or anything of the kind. That is quite bogus!

 

Now lets say I create "thought problem" example. In my world, Euclid's 5th Postualte

has been relaxed such that the presence of mass or energy density determines the local

curvature of space. A 4-dimensional coordinate system "labeled" "spacetime" can guide

me through this world so that I know where I am. Knowing the velocity I am moving

with respect to an alternate observer, I can compare my clock with his to know whether

there is a difference in passage of time. Viola! I have now just done what you proceeded to

do (in reverse).

 

Now, granted, this was presented as a "thought experiment." But then so was the Minkowski/Einstein/relativity *theory* of "spacetime" and in particular "dilated time."

It is true that Einstein (borrowing from Minkowski) use "thought experiments" to derive

the answer of dilation in time and contraction in space. However, Einstein used that

Experiment to form the groundwork to conclude something outside of the Experiment.

You have used a "thought Experiment" to conclude you answer. Not the same. :):naughty:;)

So... the above can be seen as just another thought experiment. It is in fact, the way I have "seen" Reality all my life. ... And It doesn't "slow down" just because our clocks can't keep absolute cosmic time under the stress of various gravitational and other inertial changes "relative to each other."

I guess you don't use GPS to calculate where you are. The Coordinate system used

as part of GPS takes account of the dilation of time from both GR & SR. The discrepency

may only be a few microseconds. Though that accuracy allows the resolution in distance

to be within 10 M in space.

Just a little food for thought to sleep on.

Hope it doesn't give anyone nightmares!:eek_big:

No nightmares here. :shrug:

...And then you keep saying "Time is what clocks measure." ...

With the same logic we can say that "Auras are what aurameters measure" or "Ley lines of force are what specially tuned dowsing rods measure."

 

Get my point? Ontologically none of the above establishes the "reality" of time as a dilating (etc.) medium... or "bioplasmic energy" or "ley line earth forces" as "real."...

AHA!!!

 

You have asked a really, really intelligent and challenging question here! ;)

 

I love the analogy between "time" and "ley lines". Why is the one "real" and the other not?

 

It just occurred to me that nobody ever bounced an electron off a chronon, thus proving that "time" existed and was mediated by a particle.

:lol: :shrug: :lol: :hihi: :lol:

 

Seriously :) what IS "time"? I'm just brainstorming here.

 

Time is not a static "thing" like distance or dimension.

Time is a manifestation of changes of state.

Time is a manifestation of the sequential nature of state change; a thing or collection of things goes through a sequence of states.

Each state is observably unique in some way.

Time is a manifestation of the monadal identification of state; a thing or collection is in exactly ONE state at the boundary between past & future.

Therefore, time is a manifestation of a sequence of singular, monadal state changes.

Since these state changes cannot be simultaneous, then these states must be "spread out" over some locations within a state-space; like a sequence of points on graph paper.

This separation of the individual state-space locations is a measure of "occurrence".

Individual state-spaces "occur" at different points within this continuous state-space metric.

This state-space metric is what we "locally" call Time.

Time derives from vastly ongoing, continuous, global and micro sequences of singular monadal state changes in matter/energy. These state transitions can, at some convenient scale, be observed and tracked.

The clock does not track Time; the clock tracks its own carefully configured internal state transitions.

Time could then, in theory, be brought to a halt if matter/energy could be configured such that it was permanently in one state and there were no state transitions possible.

The internal state transitions of matter/energy are not driven by "time"; they are driven by fluctuating gradients of mass density and energy density; from the cosmo-macro scale all the way down to the sub-atomic quantum scale. At every scale, gradients of mass density and energy density "flow" like waves in all directions; their "flow" is itself a self-organizing, self-actuating sea of directed state transitions. And these "flows" perpetuate and trigger all "events" (state transitions) at ever increasing scales of distance.

There is a joke that "Time" is that property of the Universe that prevents everything from happening simultaneously. It's not a joke. But it isn't "Time" that does this; it is the property that any subset of the space/mass/energy can only be in one singular state.

Observation in its most basic sense, requires an observer that has continuous internal state transitions; the only way to observe an "event" (state transition) outside of the observer, is for that "event" to affect a corresponding "event" (state transition) inside the system of space/mass/energy that we call an "observer".

It is this self-organizing pairings of external/internal events that make up what we call "perception".

Our perception of Time (in a local sense) is merely a measure of the number of sequential events that we can perceive; this is a function of our atomic and chemical makeup, in that very simple space/mass/energy systems can "perceive" more external events than can a very large complex space/mass/energy system.

The Rate at which our internal space/mass/energy system can identify or perceive external state transitions is our perceived flow of time (local).

Time (global) can be tracked only to the extent that there are space/mass/energy systems, at a specified location, which respond to global (at all scales) gradients; if there are many such systems independently responding to gradients, then Time (global) at that location "flows" at all Rates to which the systems respond.

Therefore, :eek_big:, outside of a sentient space/mass/energy system with a well-defined local time scale, time (global) flows at all time scales.

At any given point (and only a point) there is no one flow of time or scale of state transitions. There are potentially state transitions at ALL scales, and therefore, rather than there being "no time", I posit that there is (are) ALL times, ALL time scales, ALL rates of state transition, as the point is bombarded by mass/energy/gradients of ALL values.

Our self-aware sentience, complex as it is, experiences only a very narrow bandwidth of mass/energy/gradients and the corresponding internal "perceptive" state transitions.

We think of our local Time sense as an appreciation of Time as it is & as only it can be. The way TIME REALLY IS.

We are blind.

Just as our eyes can only perceive the EM spectrum in one tiny bandwidth, so can we only perceive TIME in a tiny bandwidth.

Does TIME "exist"?

Wrong question.

Do continuous monadal singular state transitions exist at every spacial scale? Yes.

Are they driven by continuous, from every spacial direction, mass/energy/gradients of every conceivable amplitude? Yes.

That's what exists.

All else is semantics.

...And then you keep saying "Time is what clocks measure." ...

With the same logic we can say that "Auras are what aurameters measure" or "Ley lines of force are what specially tuned dowsing rods measure."

 

Get my point? Ontologically none of the above establishes the "reality" of time as a dilating (etc.) medium... or "bioplasmic energy" or "ley line earth forces" as "real."...

AHA!!!

 

You have asked a really, really intelligent and challenging question here! :)

 

I love the analogy between "time" and "ley lines".

 

I like it too. I think it was originally brought up in post #137

 

Think of the magnetic

field lines a person could draw around a magnet

. The field lines are not real physical things. But, that doesn't mean electromagnetism isn't a real physical thing. It doesn't mean that Maxwell's theory of the electromagnetic field is wrong.

 

One might be tempted to say that magnetic field lines are not real and not physical but are rather something like a map and therefore magnetic field lines must be straight (they cannot be curved). This is analogous to saying the spacetime manifold is not real and not physical but is itself a map and therefore it must be straight and uncurved (i.e. space and time cannot be curved).

 

As I've previously said, that line of reasoning does not seem sound to me.

I would not be so tempted. Magnetic fields are obviously curved. The Earth's... a bar magnet's... solar flairs... the aurora borealis. We can see the curvature as expressed by iron filings on paper over a magnet... or in the display of ionized gases near the poles.

As above... you usually totally misunderstand what i am saying. Your example above was a totally false representation of my "line of reasoning."

 

Like the curved path of light around masses, the curved force field of magnetism does not establish "The Curvature of Space." It is a "fabricated medium"... only a model... unlike magnetic force fields and curved light paths.

Amazingly enough, straight lines, however "geometric" are still straight lines... both on paper and through space...

And the "objective distance" (however much you hate that phrase!) "through space" between two objects (or points on paper) is still a straight line... not the light path by which we 'see" objects.

 

. Would you please step aside and let this thread progress without your distortions of what I am saying here??

Your magnet example completely misses my point... as usual. (as per my above comments.)

 

A brief exercise in logic...

Assertion: "Time is what clocks measure." (Implication: If clocks measure "it" then "it" must be "real" (as an entity of some kind.)

 

Assertion: "Ley lines are what specially designed dowsing rods measure." (Implication: If dowsing rods measure "it" then "it" must be real (as a real Earth Force of some kind.)

 

Your curved magnetic field doesn't even approach the ontological debunking of 'time as established by clocks' presented above.

 

The sorry truth as I see it is that you have no idea what I just said!

Clocks don't measure time; clocks make ticking noises.

We measure what a clock 'says', a clock just keeps ticking, because we make it.

Yes. I just said that. Clocks measure their own internal changes of state.
