How can an object occupy two locations without invoking time as a parameter?
By moving. The "parameter" is location, although parameter is a bad word to use because it generally refers to quantitative measurements. Hopefully the moon moves whether we measure it or not.
By moving? How is that for a circular argument

? Moving is "occupying more than one location" and occupying more than one location is done by "moving"?
The definition is not circular. The *definition* of motion is more than one location of an object. This is a noncircular definition.
It would be circular if motion was defined in terms of location, and location defined in terms of motion. Then we would have a circular definition.
The mechanism is "circular" only insofar as "how" was an incorrect question in the first place. Instead of recognizing this immediately I just gave you the definition of motion back.
Asking how involves a theory or a description. For now we are merely defining motion in a non circular way so that we can then develop theories involving this concept. Certainly we cannot describe or explain "how", i.e. propose mechanisms and theories, until we have defined what we're talking about.
You might ask "Did this object move?" We define motion, and the object either moved (or didn't) pursuant to the definition of motion. Was my hand at more than one location? If yes, it moved by definition.
Now, you might ask "HOW does my hand move?" One might then go into a long speech about muscles and neurons. This is a theory. This question *presupposes* that your hand did, indeed, move. If one has not even defined motion then this presumption is unfounded. One cannot even rightly say that the hand moved, much less explain how it moved with a theory! If the hand didn't move then his/her theory is all a bunch of hot air.
So your "how" question is premature. We are not there yet. We have to agree on what we mean by "motion" before we start asking questions like "how do the planets move in ellipses around the sun... etc." Certainly if "move" means something different for both of us, we cannot discuss such questions productively.

Nature doesn't know anything about "more than one location". The moon looks at herself and says,"I just have location." The moon doesn't "remember" where it was, or guess about where it will be. This is a human activity. Nevertheless we need to define the word "motion" so that it doesn't require a human observer for verification, hopefully the moon moves even when we are not "looking". If an object WAS at more than one location, it moved by definition. Now, the moon moved whether we looked at it or not.
Since two objects from your definition cannot share the same location I think nature does care about "more than one location". This description you give appears to me as Einsteinian relativity that says: "every observer's frame of reference can be viewed as the motionless center of the universe". So, what's new?
When did I say that two objects cannot share the same location?

altonhare wrote:Absolutely! 1D points are quite the joke. But can you believe that some "physicists" actually say that position (and sometimes location) are 1D points? I have trouble believing it myself. Maybe they just don't think carefully before they speak.
So, you don't believe in one dimension, but you are fine with three?
It makes no sense to "believe" in concepts, including "dimension". You simply define your concept, in this case you simply define the word "dimension". It has nothing to do with belief. What do you mean when you say this word? As long as you define it, I can follow your argument and theory. Whether I believe your theory or not is up to me.
So if the beginning of your "theory" involves 'a' 1D 'object' then you simply have to show it to me, or show me a model of it. If you can't do that I can't follow your theory. There is nothing for me to visualize, no actors in the play, no play, and no theory. You can write all the equations on the board you want and tell me about all your great experiments, as far as I can tell you got equations to match the data. This is not an explanation, it's a description.

So what is a photograph *conceptually* then in Gaedean physics?
It is used to express that the concept we are referring to is static, i.e. it doesn't involve motion. Nothing has to move for us to define or understand this concept.
That's a contradiction. You cannot prove with a "photograph" that an object is not moving.
Who said anything about proof!? Here we are talking about definitions! A static concept is one that we can visualize without motion. Bill likes to use the analogy of a photograph. Static concepts are conceptually photographs.
We haven't gotten to evidence such as polaroids yet. We're still getting the terminology straight so that we don't talk past each other and in circles for hours and get nowhere. Also so we don't end up in fantasyland with the theists.

Every location of every object is in every frame. There are none missing. Humans might miss some of the frames or sometimes fail to account for them, but Nature doesn't.
StevenO wrote:
Every location of every object in every frame is not a meaningfull description if you do not describe what separates locations, objects and frames. What about objects that rotate, so don't change position, only orientation?
I don't see what your issue here is. First off location is conceptual, so asking "what" (implying what object) separates locations is nonsensical. A wall cannot separate love and hate. As for objects, two objects are separate by definition because they have different shapes. If they were not separate they would have one shape and would be one object. I don't see why anything has to separate the frames, this makes perfect sense to me without invoking something else.
Location is not conceptual, as it is defined by your "objects", which have "shape", so they are real and separated by "not shape" (I have to assume, otherwise there would be another object there). By the same logic something will have to separate frames, otherwise they are the same, so what is it?
First you say that objects are separated by nothing, by which you mean there is not an object between two other objects. This isn't quite right, as I said that objects are separate by definition (because they each have a shape). But then you insist that SOMETHING (some object) must separate frames. And you say it is "by the same logic". No, by your "same logic" we would say that nothing (no object) separates the frames.
Location is most definitely conceptual! Location lacks shape, all objects have shape, and whatever's not an object is a concept.

Bill is saying time is motion+observer. A human being remembers the (locations of objects and compares them to current ones, defining a concept "time". Inanimate objects don't engage in this activity.
StevenO wrote:Any physics property needs an observer, you can't say some are more equal than others. So, you do agree that time is an integral part of motion?
The FIRST thing we do is kill the observer. Hopefully Nature operates the way She operates even when we're not looking. So we need to define words like motion and object so that they don't require a human to come by and verify whether 'it' is moving or 'it' is an object. Objects are objects whether we're observing or not and they move whether we're observing or not.
The observer is what seperates physics from philosophy. No measurable quantities means no physics.
I didn't say there was no observer ever. I said the FIRST thing we do is kill the observer. We can bring him (or her) back later if we need to. The point of this is to distinguish clearly and unambiguously between what is "out there" (observer independent) and what is "in here (mind)" (observer dependent). By itself, a clock just moves, it just goes "tick tock". "Time" is what an external observer derives from observing the clock. In physics the first thing we do is to distinguish between what the universe does "when nobody's looking" and what we personally derive from observing the U.

See above. Why would objects be real and move even if we don't look, while time not? If we do not observe we cannot prove anything.
altonhare wrote:In science we need to be careful about confusing what something does all by itself, and what we get out of it. Put another way, we need to distinguish clearly and unambiguously between what's happening out there (in Nature) and what we, personally, derive (in our mind) from what's happening "out there". Time is a result of memory, a property of our mind. It is what an external observer *derives* when they see motion.
Anything we communicate comes from our mind. Now, how would you prove that time is unreal and objects real or the other way around? Do you have an experiment that can decide between that?
First of all, it is a common fallacy to talk about proving existence. We don't prove "real vs. unreal". Second of all, it makes no sense to prove concepts with an experiment. You DEFINE your concepts from the get-go.
Motion: 2 or more locations of an object
Time: COMPARISON of 2 or more locations of one object with 2 or more locations of one (or more) object(s)
Motion does not require our presence. However time does. Time demands that a person make a conscious comparison between the motion of the clock hand and the motion of something else (distance-traveled to work so far?). We must make clear that Nature, by itself, does not sit around "keeping time". In Nature objects just move. A theist may believe there is some all-powerful "God" that compares motions between all objects in order to "keep time", but not the scientist. The scientist recognizes "time" as an observer-related phenomenon and motion as observer-independent.

You are the one claiming fields are not physical, against mainstream knowledge (especially on an EU forum). But for sake of expedience I could quote the knowledge that you are refusing to study for you:
A field in physics is a physical quantity associated with each point in space-time. For example, the gravitational field is a vector field that represents the magnitude and direction of the force exerted on a mass in this field.
A quantity? A number on a page? I've never seen one of those "blend with space" i.e. "become nothing", disappear, lose shape, etc.
Yeah, but luckily for us it keeps our feet on the floor, or stretches a spring if you put a weight on it. You can deny physical measurements any way you want, that does not make them less real. But hey, "truth is no match for belief

Numbers on pages keep our feet on the ground? Steven you're too funny! I'm writing this one down to keep as a joke for later.
Bill: Ropes that mediate light also keep our feet on the ground.
Steven: Numbers we write on paper keeps our feet on the ground.
Your proposal is so much more reasonable.
