OK. Let's take a look, shall we?
If you are an astronaut, floating in space, with nothing in sight as reference, and you say: 'I have travelled 10 metres ahead', that can be up, down, or forward horizontally, correct?
Actually: Ahead implies it can only be forward in relation to your current facing. I.E you have no dimension. And your direction is relative to your current facing. There is no dimension involved in a statement like that: Which makes it a poor way to navigate.
Now if you did have some other point of reference, say the spaceship right next to you, and it's nose is pointing in the same direction as your head, then you might be able to say that '10 metres ahead' is the dimension of depth, height being the vertical dimension with reference to the spaceship and your head, and width being the horizontal dimension left to right.
You asked her not to mention dimensions. She didn't. You are still arguing about this somehow. This is all my post is about.
You most definitely cannot say that "10 metres ahead" is the dimension of depth: For that you must know the target. But "10 metres ahead" does not mention any target: It merely implies going forward from your
current position and facing.
Again, a poor way to navigate.
But if you have no reference, only your body, then '10 metres ahead' could be height, width, or depth, but most likely would be depth, which would be looking straight ahead. But 'straight ahead' can be up, down, or forward.
Firstly, depth requires at least two objects in relation to each other. "10 metres ahead" doesn't give you a second object. Therefore, it automatically disqualifies depth. Second, "up, down" and even "forward" are relative. What if you are lying on your belly on the floor, looking down, and were to go "forward?" How would you even decide what's forward in that instance? What of outer space? What is up and down there?
ChristineM said that 'space is those dimensions', which I assume means height, width, and depth.
Space / spacetime and dimensions are all concepts of physics. And in that context, she is right.
And you have to understand that space and time themselves are relative. And observer dependent.
Space is dimensions. Including time as the fourth.
'10 metres ahead' must refer to one of them, but she did not say which.
It doesn't refer to any of them, but it will result in you moving in some dimensions, relatively speaking, relative to your current facing. But you ONLY asked her to not use the terms.
Doesn't matter, since all are dimensions.
It matters in the way that it's not actually referring to any dimension, which, again, makes it a poor way to navigate in space.
All I am asking, then, in reference to her statement, is 'where, then, does '10 metres' exist inherently in space without referring to the device used to determine those values ie; '10 metres'?
Are you now forbidding the use of the term "10 metres?"
Not an entirely fair argument if the other side has to honor your increasing conditions.
If I say: 'from here to there is about 10 metres, I am not referring to what exists perse as 'here to there', but to the device used to come determine the value '10 metres'.
So, when you say "from here to there is about 10 metres" you are actually meaning "ruler?" You can't entirely blame other people for not understanding what you're trying to say when you're being this cryptic.
You either determine the value "10 metres" by using a ruler, or by making a guess. In which case, again, a poor way to navigate.
Also worth noting: She didn't say "from here to there." She essentially said: "from here..."
If I am incorrect here, kindly point out the error in logic I am making.
No, thank you. This has been too easy.
If you want it simplified: The major problem with your logic is that it assumes a lot of extra data that wasn't inherent in the original claim you are trying to argue. No dimensions were given. No additional objects were given to be used as target. Only this information is known from Chrstine's comment: Going ahead from your current relative position and facing. And you only have yourself as reference point. That's it. Anything else you assume, is extra and shouldn't be part of your logic.
You simply assume a lot. Almost all your points are assumptions that weren't included in the claim you are actually arguing. I suspect it's a distraction attempt, and a form of moving the goal posts. Additional claims, additional conditions and voila, your argument can now resume. But only then.
You expect to win arguments by putting conditions on your opponents. By my count, it means you already lost before you started.
