if space is indefinitely divisible, how is motion real?

>> No.14545236

Ancient Greek fags didn't understand the essence of the calculus until guys like Archimedes came along. This is an example of that fact.

The notion of covering some distance in space is an imaginary construction of the mind. Perhaps "motion" is "real" in some sense, but not in the sense of covering distance.

1st solution: there aren't divisions because limits are a cathegory only from your mind and reality is a continuous

2nd solutinon: the are minium divisions in space, something like Space atoms. And motion is due to a pre-established harmony

That doesn't "solve" anything but merely restate the problem: if you subscribe both to the notion of continuity and of movement through space as gradually covering some distance, it implies a realized uncountable infinity which seems like an absurdity.

Is "indefinitely divisible space" an abstraction, or idiocy? Both seem to exist in OP's head.

>> No.14545365

>>14545357
Not OP, but "infinitely divisible space" is naturally just an abstraction because divisible space is just an abstraction because divisibility is just an abstraction.

>> No.14545388

>>14545232
For christ sake this has been solved for eons. Finite time. The dimension missing in the calculation is time and reference frames. It does not matter at all if space is infinitely divisible, the same way it does not matter that on the whole you cannot determine motion if you are a point on an infinite plane.

Let me illustrate it like this: On an infinite plane you cannot be said to be moving, the same way you think infinite divisibility means you cannot move. Except you can, because by making a marker relative to yourself you plainly are moving *relative to the marker*.

The fundamental mistake of thought experiments like these is the lack of understanding that infinities don't "break" things because your reference frame IS NOT INFINITE.

That paradox is mind bogglingly retarded.
Yeah he has to cover so-and-so distance. And he will do so, in less and less time because neither he nor the turtle are changing their speed. Just because you look at an infinitesimal subdivision of time and see they moved an infinitesimal distance in that time won't change the fact they are still moving at their respective speeds.
It's like looking at their positions at just a single time(when they pass each other), and claiming that nothing is moving... Well duh, you need more than one point in time measure speed!

All of us on /sci would like to know how you explain to trooper Bubba that speed is a fake concept.

You're a seething materialist wannabe philosofag who still hasn't realised that "impossibility" is an abstract claim about the nature of the world. To ignore another abstract concept (mine) whereby the supposed paradox you present may be resolved, because you consider it to be too abstract is ironic. You believe there is a paradox or impossibility but when I point out a possible logic whereby that paradox may be resolved you claim that it can't possibly have anything to do with the real world. So what is it? the world obviously exists, it is a possibility, so obviously there is no real paradox and the possibility must be due to some logic like the one that I proposed where the paradox cannot exist, but you claim it does so you ignore solutions like mine because they are "too abstract", but what's more abstract, navel gazing way of approaching this problem? believing in a reality that is intuitive conceptually for the sake of being intuitive conceptually or subscribing to the conceptual framework that best explains reality?

What kind of retard do you have to be, to believe what you said is an argument?

Literally just look at OP's picture.
Maybe seeing numbers will activate your neurons. Say the guy moves at 10km/hr and the turtle 0km/hr. And there's 1km between them.
He will run that 1.0km in 6:00minutes. No exceptions.

But first he runs 0.5km in 3:00minutes?
Then 0.25km in 1:30minutes?
Then 0.125km in 0:45minutes?
...
See both those numbers getting smaller? So what? It doesn't matter if he moves 0km in 0:00minutes, he will pass the turtle.

>> No.14545745

>>14545636
Ahh, I see. You're not even going to bother engaging with my argument are you? Great. Well that's disappointing for sure but it not entirely unexpected.
Funny that you accuse me of being off my rocker however. You're the one who is arguing that motion is impossible or that this ancient problem invented before the advent of the calculus somehow is saying something meaningful or philosophically interesting outside of the normal slightly non-intuitiveness of the calculus.

I'm arguing that stuff in your head is just stuff in your head, so it's unsurising that it bears all the hallmarks of head stuff, like "infinitesimals" and realized infinities. Anyway, nothing you sharted out is relevant or an argument.

Since when is that a problem? If you have a problem with there being a difference between concepts and reality then stop using language, faggot. Calculus is too hard for you. Ooga booga boo!

Well, you could just imagine the universe as a single unchanging object, and "motion" as an artifact of a brain sampling slices of this object. The math works out the same.

> If you have a problem with there being a difference between concepts and reality
I don't. You apparently do, since you can't let go of the idea of realized infinities and accept that your view of motion only makes sense as an abstract mental model.
