...so basically it has to move at a non-constant / exponential rate so that it can move to one halfway point between a halfway point between a halfway point etc.
You do realize objects DON'T move at exponential rates? you don't fire the arrow, wait two years, then in half a second its at the target.
in order to reach the halfway "point" it must do so at a particular "point" in time. but what's a point in time? if durationless point then it cannot be considered to consist of or comprise time, and if not then it's a span of time and can be infinitely reduced. the problem is that time and space are mutually defined in a way that they both validate and negate each other. they're the same and yet different. this paradox of finite/infinity is everywhere: time, space, numbers, binary opposites...
Movement is change of place in relation to time, so without time you can't have motion. If you stop the time the arrow will be stopped as well because for motion you need time.
it would have sense, if there would be a energy loss at each halfway of a halfway. but there is no real "halfwaypoint" that is marked somehow. this is just theoretical. so this is just stupid.
Wrong!!!! All matter is in a state of constant motion. (unless at absolute zero, which at the current point in time, only exists in theory)
If you keep halving and halving... you get down to the atomic scale, and because of vibrations due to thermal energy, the atoms are always crossing back and forth over this half way point.
All it takes is more energy to cross more half way points.
Just because there are infinite half way points, doesn't make this impossible
isn't this flaud because an arrow cannot move without us as humans putting it in a bow and the process you just said imagine an arrow going through the air so it is not an example but a hypothetical scenario
Part of why I disliked was to be the #1337 dislike. But seriously, I don't like dramatic video descriptions of paradoxes like these because WE KNOW the fallacy and yet people will still be encouraged to come up with bs pseudo-philosophical banter.
This paradox only holds true if the object in motion stops at the halfway point, such as, it runs out of energy at the halfway point. The paradox is broken when the object in motion crosses that point. It'd be like an airplane or a car only having half the fuel it needs to get to its destination or a hiker only bringing half the food they need to get to their campsite.
It's kind of interesting to think that an apparent eternity goes on between every event in our lives. I guess it could be said that everything is infinite by virtue of existing, and we only perceive it as otherwise.
What the ancient greeks did not understand was that even though you may have a finite length of string you can always cut that same length of string into ever smaller halves. This does not mean that the string was never whole.
The same goes for movement - the finite amount of time an arrow has to travel can be cut into ever smaller halves.
That's pretty dumb. The fucking arrow is fucking moving. If I stand up and walk to the other side of the room, I'm fucking moving.
Yo dawg, we heard you like halfway points so we put a halfway point in your halfway point. Shit like this isn't philosophy, this is just over-complicating simple matters to make the speaker feel more intelligent.
@noob5000000 noob is right. this paradox is one of the principles of Calculus, fuck head. It's not that the speaker seems more intelligent; it's the speaker being more intelligent than your degenerate 21st century fuck-tard ass.No wait, you're right! Aristotle is an idiot. You know, being the father of fucking logic and all. Yeah, Aristotle is an idiot. I have to go commit suicide now that i know the world is full of fucking morons! btw, it was Zeno.Aristotle just commented in bk3 physics
@Metticus You do know the dark ages were brought on by the Catholic Church burning all of the "Classics" such as Aristotle, Socrates, and Pluto right? Not the philosophers at all.
The answer to this 'paradox' is in quantum physics, but it can be summarized like this: sub-atomic particles don't move in the conventional sense. They can exist in a sort of 'cloud' of probability until they are observed. When they are observed, they can be somewhere entirely different from where they last were, without appearing to 'move' at all.
Philosophers may explore ideas and old paradoxes for whatever reason they always have. The solutions to the questions they ask, like why we feel the things we feel, how we experience reality, what life is, where the universe is heading, these millennia old 'paradoxes', are now all well understood by biologists, neuroscientists, physicists and mathematicians, yet philosophy somehow keeps on truckin'.
@666or999 Not at all... Aristotle famously believed that the brain was primarily a heat exchanger... The nervous system wasn't really understood before the 1800's. Before Edward Hubble, many believed in a static universe. Christian countries have been waiting on the four horsemen of the apocalypse for the universe to end, with numerous countdowns and disappointments. Look up celestial spheres. Science opens up the universe with discovery, something that philosophy fails to do.
@JaySmith91 I'm refering to the questions 'like why we feel the things we feel, how we experience reality, what life is,' and don't confuse philosophy with religion. Also it should be noted that science itself came from philosophy
@666or999 I'd be interested to know how these questions were answered before the development of neuroscience. Evolution is the cornerstone of modern biology and all the fields that stem from biology. I wouldn't say life was well understood prior to work in molecular microbiology and certainly not before Darwin's time. I think philosophy might be more appropriate alongside history, as it's definitely not a good quest for new knowledge.
the assumption with philosophers who think up this paradox is that time dilates when space gets smaller. Of course this assumption is wrong. For every instance space is halved, time is halved also. Of course we have to assume the velocity of the arrow is constant. You can assume it is possible to half space an infinite amount of times, but when you do time equals 0, hence since a moving body is not at rest, the arrow will always have a finite distance to reach it's target. Paradox solved.
I think there are some basic problems with describing this Paradox. Firstly, you assume that you can measure a point in space absolutely. Neither an arrow or a target would be able to occupy a singe measurable point in space. Therefore, there cannot be a half way point to measure. (The more you 'zoom' into an 'edge' of an object, the more difficult it becomes to delineate it from what surrounds it.). Equally, you cannot ever say accurately that the arrow has reached the target.
@SpiderRift That is the assumption made, but it's wrong. The arrow has kinetic energy the instant after your record it's 0 displacement; no matter how small the distance it travels. In that instant the arrow has a finite time it has to reach it's destination before it violates newtons law.
Using this logic, time must stand still too. To get from 10 to 11, you must first get to 10:30, but before that 10:15, 10:07:30, 10:03:45, 10:01:52.500...
@DaffyDaffyDaffy33322 Yeah, theres a whole bunch of related paradoxes around Zeno's paradox that revolve around the nature of the infitesimal. Where they become basically wrong is that time etc seems to be quantized, theres a minimum step that things don't become smaller than, and thus the infinite regress described fails at that point. Sort of. Shit gets messy when you introduce infinity into things.
This is silly. You imply it's impossible for an object to reach a halfway point between where it was and where it's going? This happens all the time...! What would make it impossible? Silly.
@CaptainDummyTalk There are an infinite amount of half way points and as you know infinity is impossible to attain therefor the arrow couldn't possibly pass through them all, hence the arrow never moving. It's more of a quirk within the concept of our description of movement, not an actual logical scenario but it's funny none the less :)
only in theory. but as the act of movement is not based on finding the midway point but only in the action of movement, this trick is only cool if you're stoned out of your mind.
But if a point is infinitely small then there would be more and more space between the point and the tip of the arrow, so it would have to move to reach it.
And the answer to solve this lies in that 1. V=A/D*T. And for V=0 A=0 but because of a downward force of gravity says that A is 9.82 in a downward vector meaning that V must be something. So it has to move. And the other paradox is when you reach halfway you still have halfway left... so the arrow doesn't move at all even if it looks like it hit it's target it haven't which is true at quantum physics.
so if i shoot an arrow the opposite way to which the earth is spinning the earth will quickly spin the other way to get the arrow where it needs to go lol?
...... what she is saying is: since the arrow can't travel the distance x without travelling the distance x/2 first, it can't move.
Of course this is true, everyone just teleports an infinite short distance an infinite amount of times to move. Basic logic. Also v=ms is false because time is an illusion.
@hautster This movie maker has no concept about modern mathematics. In fact, the sequence is bounded. SO infinity times distance will be a constant. So it is not impossible.
We now know that you can't go infinitly dividing a distance in half. You will eventually go to the scale below the planck length where you can't divide the distance in half.
So something like quarks can only go a static point forward, bakwards, up and down? Quarks can not go half way of length of other quarks and half of that length again? I wonder how that will effect how quarks align together. Maybe you are on to something ;)
This has buged me my whole life. . I think i've finally figured it out. The latest advances in quantum physics teaches us the mindblowing fact that all matter behaves a certian way when observed by counsiousnness. In truth the atoms that make up the arrow are everywhere in every possible position in the universe. It is only our observations that present the illusion that the arow has moved. it didnt realy move we just observed it at different points in time. check out my play list about realiy
@kakoiarekkusu well you need to take a first step before you make a seconed step right? if you didnt take that first step, than you couldent take the seconed one could you? do you get what im saying?
Just like everything else in nature, time and space are fractals (look that word up) which means infinity can fit in a finite space, just like it was demonstrated. Movement is just a frame-by-frame illusion of an infinite number of parallel realities that ends up creating the effect of time; therefore, time is just how long it takes any kind of movement to take place.
infinitie parallel universe has the same flaw but only in disguise. If there exist an infinity many universes then there is always parallel universe being added. We have everything and then we add one which makes a new everything. Infinity without assuming it converges to spesific number is still unsolved.
It is just like gravity. We know it is there, but we can not tell why and what it is. But maybe there is still a link between infinity and finity to be discovered;)
@steverock85 Maybe rather than one reality 'added' to the last, it replaces the last. Which also implies the idea of non-locality and time would still be the effect from motion, i.e. the concept of the 'here-and-now' is all that exist & time/location is completely illusory.
So you define infinity somethink like an stack in array. And the last entry is removed when new comes in. Or did you mean something like an queue? That first entry is removed when new comes on top?
Why is that any more logical than one being added? Is that not just onother disguse for the same problem? And if it was so, then what is this finite number of parrael universe before the stacks or the queus get changes and what is the rate of this change?
@steverock85 (1 out of 2 comments) I guess its like a queue of infinite parallel 'possibilities' that actually never exist except when present, but the possible reality that becomes actual reality is defined by the situation before it..So the past reality defines the present reality and you could say the present reality defines the 'next present' reality... B/c of this there is no 'finite number of parallel universe before the stacks or the queues get changes' b/c.............
@steverock85 (2 out of 2 comments) .........past & future realities don't exist, there is only one reality 'to count' or to experience, and we call that the present & and the present reality has no movement & no time...The rate of the change must be infinite b/c time/movement is divided up into infinity, like i mentioned in my first comment, infinity can fit in a finite space by virtue of fractals.
I know what they say in the quantum physics. But this does not really solve this paradox. With this you are giving up on explaining what infinity is and using it to fill in the gabs.
The reson of this paradox is to highlight how infinity causes fallacies. You can also consider the liar paradox.
You can also just skip those paradoxes and try to directly tackle infinity.
@steverock85 Well, i guess infinity is the paradox & we cannot understand this concept... but do we need to understand it? If you an infinite amount of moments or realities that proceed each other w/ an infinite, or basically no time at all why would those two infinities cancel and leave us with the linear time that we experience?
You are correct, we do not need to understand concept of infinity to go on with our lives. This is the only way we can see this but it does not solve this paradox. For this paradox to be solved, we need to understand what infinity is as we are looking at each interval. It is the observation that makes each point static.
@steverock85 Maybe the only point that is observed is the present moment, and it does disappear once it is no longer being observed...kinda cool stuff though
But the trick is that in our mind, we freeze the time, and give each observed point a static point in time. Thus observing itself will diverge to infinity while the movement of arrow will converge.
Kind of like the liar paradox. Now who is telling the truth of what is really happening. Also what is distance at all. In math any distance can be broken down to infinty, but yet, the distance it self is finite.
@steverock85 Yea, i think their are two truths/sides to every observation that really happen, which of course is what results in the phenomena of the paradox. One truth is perspective of the eyes and the other is perspective of mind, like you mentioned...to be honest with you, being able to have a conversation like this one is enough to prove to me that we are more than just a body and a brain...but ive had other experiences that led me to believe that anyway;)
Everything said contradicts this whole theory, "Before it may reach the target it must reach a half way point" To do either the arrow has moved. To reach is to to get to or get as far as in moving, going, traveling, etc. To even consider this as a paradox you dont understand basic physics.
@Nacherel Ok, then consider this. When it will move, what will be the smallest possible unit of distance?
The very basics of math is about magnitute and quanity. You are free to think this is not a paradox but it shows in very simple way how limited that thinking is to descrepe our world when it comes to infinity. We can approx when the value converges to specific number but that is all there is to it. This is seen for example in pythagoras, irrational, series and limits.
And when it comes to our known world, infinity is but a title of nothing like everything and forever. Perhaps one day, these questions will have answers. Perhaps there is no answer?
And even so, what has this got to do with movement, and the so called paradox?
Hehe, yes this paradox will end when we have found the smallest possible unit :) And we could think light speed as the divisor for the time as nothing can go faster than light(well, neutrino seems not know yet..).
It is more our observation and attention to each point rather than the movement itself. But what is movement at all? Can you explain it? If the whole world was only two moving footballs heading for each other, then why do they move at all?
It isnt a paradox, everything moves, the electrons of an atom have no position, they are constantly zooming about sharing a wave from like everything in the universe, you and me share phosphorus from a meteorite ten thousand light years away from an undiscovered galax
As far as I'm concerned this is little more than a pathetic attempt at sophistry by a person lacking an understanding of basic mechanics in combination with simple algebra.
The fact that this still seems to impress people today is a tragic commentary on an educational system which seems to prove time and time again that a LITTLE knowledge is a dangerous (in this case annoying) thing. You may as well make a video about how enthralled you are by the predictive capacity of your weekly horoscope.
To understand what is going on try look at this. Let distance be m and 2^n, n>1 be the division of time of this distance. So we have sum of series that will equal one or:
m/2+m/4+m/8+m/16+ ... +m/2^n = 1 (or almost one...)
You can put "sum 1/(2^n) from 1 to infinity" in input in wolframalpha . com to see what is going on.
The time to travel will not change, nor will the distance. This is more about what time is and what happens if we focus on each step in the way.
Or the "sum m/(2^n) from 1 to infinity" in the input and get m.
m/2+m/4+m/8+m/16+ ... +m/2^n = m not = 1... sry about this...
The paradox is that there will always be fraction missing that makes m or 1 whole. Kind a like sqrt(2), pi or any irrational number or rational number like 1/3, which can not be repisented as a magnitute in its purest form. ex: sqrt(2) = 1,4142... and 1/3 = 0,33333...
@steverock85 There's no paradox. After time T the arrow reaches the half way. After time 2T the arrow is at the end. There is no fraction missing when time is over. There is no paradox. There is only the mistake in thinking, that the time unit of observation are getting smaller (or equivalently the speed is decreasing), which, of course, is not allowed, because the arrow in reality is not getting slower either.
If we let the distance be 1m and the speed to be 1m/s, how long will it take to arrive to 0.5m?
That would be 1/2 of second right? You are not changing the speed, it is only 1m/s * 1/2m = 1/2s. And how long takes it to get to half of the half of that distance?
1m/s * 1/2m * 1/2 = 1m/s * 1/4m = 1/4s.
Sry I did write this in a confusing way as you might think this is 1/4m/s which it is not.
@steverock85 Why is that a paradox? For me, there is no paradox. It is only that philosophers from 3000 years ago or so wanted to tease / provoke / spite / ... whatever. Mathematicians explained it. This topic is stupid, I'm wasting my time with it. However, I have learned in this discussion that today there are still people which fall into this trap and do not understand that it is a stupid flight of fancy.
I will have to assert the football example again to proveke this paradox even more. We know today that every moving objects needs energy to move from each other and to each other. What was this first energy?
If the universe was only one football and one goal, then who kicked the football? O_O That is another paradox related to this one.
You tell me math has solved this paradox. What is the name of that proof?
@steverock85 The fact that mankind has not understood the origins of the universe does not make the existence of the universe a paradox. The falsification of the statement "movement is impossible" as well as the mathematically precise description of movement has of course been done. Computations and arguments are given below. Simple high-school mathematics do not need a name. Giving this stupid provocation a name would be a devaluation of all other respectable mathematical research.
So your proof is that we experience movement every day? Last time I checked, every mathematical statement needs theorems to be based on to be unambiguous. Even the most simple ones.
Theorems are not so highlighted in high-school but you can't study higher level of calculus like multivariable calculus, linear algebra without them less you build your mathematical foundation on leap of fath. So what is this about devaluation?
@steverock85 I do not fall into your trap. It's the other way around: The above self-contradicting video has no logical / mahematical argumentation and does not prove "movement is impossible". All this is explained in many post below. You try to reverse argumentation? You criticise me for not proving "movement is possible". The point is: The fact that the arrow has to reach half way before reaching full way does NOT imply "movement is impossible".Video makes the mistake, not me.
Don't worry, the world will not freeze with this logic :)
Yes you are right, this is what we experience in every day. But it does not change the fact that we still have no explanation. We know it is there, but we really can not put a number on it can we?
I am not saying movement is impossible, but math is a little limited when it comes to define infinity. That is all what I am saying. I do not say movement is impossible, just debatable.
"According to Simplicius, Diogenes the Cynic said nothing upon hearing Zeno's arguments, but stood up and walked, in order to demonstrate the falsity of Zeno's conclusions. To fully solve any of the paradoxes, however, one needs to show what is wrong with the argument, not just the conclusions. Through history, several solutions have been proposed, among the earliest recorded being those of Aristotle and Archimedes." - Zeno's_paradoxes - wiki
It was an attemt for a metaphor. I admit that this was an poor one. But if there were no one to kick the ball, then how did the ball start moving on its own? And if kicket, how did the kicker start to move? How did the universe start to move? This may lead us to conclution of an illusory world like what ronnyboy6o said. But even infinity parralell universes in stacks or queues have the exact same problem.
Isaac Newton resolved it mathematically. He used similar reasoning to calculate "instantaneous velocity" meaning velocity measured at a single point. His concept was to take the "change in position" DIVIDED BY "change in time." Zeno neglected to divide by time so he never came up with a mathematical definition of velocity.
Newton generalized the concept to take the DERIVATIVE of a function. Leibniz did it in Germany at about the same time but Newton got the credit.
Yes we can use the derivatie to find the instantaneous velocity, but it does nothing but support this paradox.
If you think this as in term of a straight line with the properties of a real numberline, then you can not get anywere. You can divide the line infinity many times and you can not conclude any limits of this devision.
If time is within the reals, then you can pick any point, no matter how small.
This means there has to be a finite division number in timespace.
@steverock85 The concept of limits is the only way to do infinitesimal calculations. It means you can take the smallest non-zero interval you like, but it must be a real number. Give me the real number and I can calculate the distance moved if I know the velocity. Consider y = 1/x Give me the smallest non-zero value of y that you like. I can then calculate the value of x required to give you that value of y, or less. We can't get to zero, but we can get as close as you specify.
You have to be careful when you talk about real numberline as we are talking about irrational numbers as well, how does that work in real life?
Lets consider y=1/x. Let y = speed and 1 = meter and x = seconds. Now as x get closer and closer to zero what will happen? We will break any physic law as we will travel faster than light. y will go to infinity.
On the other hand, if x will go to infinity like in this video, y will be 0... no movement at all.
No I disagree. These are NOT the conditions. In what you describe, you SLOW DOWN. Half the way in the same time = half speed = slowing down. Slowing down means that you do not want to reach the goal = point B. If you do not want to reach the point B, then there is no paradox, because you will not reach it by construction! This is then not a paradox. Mathematically, you would reach B at infinity.
The condition is: Same speed. Then it is exactly one hour. Sorry, I meant "hour" not "week".
This isn't a paradox its due to an equivocation between mathematics and universal physics. The premises are: Motion is the change in position for an object from point A to point B. There are an infinite number of points between any given points. Therefore motion is impossible because nothing can travel an infinite distance in a finite amount of time because you cannot divide infinity. Instead the problem is that there is a smallest unit of space and therefore there isn't an infinite # of points.
this paradox is assuming you can divide distances smaller than the planck length. You can't actually measure anything smaller than the planck length or time, you will simply warp to the next point, hence movement is possible because its not continuous.
that is called a limit, so let's say you want to walk from point A to point B, and each hour you walk half the distance from your current position to B, then how much would it take you to reach point B? the answer cannot be 0, because in 0 time you wouldn't be there, it cannot be infinite, cause no matter how much time you spend you NEVER reach point B.
...so basically it has to move at a non-constant / exponential rate so that it can move to one halfway point between a halfway point between a halfway point etc.
You do realize objects DON'T move at exponential rates? you don't fire the arrow, wait two years, then in half a second its at the target.
There is no paradox, it's just faulty logic.

What the ancient greeks did not understand was that even though you may have a finite length of string you can always cut that same length of string into ever smaller halves. This does not mean that the string was never whole.
The same goes for movement - the finite amount of time an arrow has to travel can be cut into ever smaller halves.

The answer to this 'paradox' is in quantum physics, but it can be summarized like this: sub-atomic particles don't move in the conventional sense. They can exist in a sort of 'cloud' of probability until they are observed. When they are observed, they can be somewhere entirely different from where they last were, without appearing to 'move' at all.

Philosophers may explore ideas and old paradoxes for whatever reason they always have. The solutions to the questions they ask, like why we feel the things we feel, how we experience reality, what life is, where the universe is heading, these millennia old 'paradoxes', are now all well understood by biologists, neuroscientists, physicists and mathematicians, yet philosophy somehow keeps on truckin'.

@666or999 Not at all... Aristotle famously believed that the brain was primarily a heat exchanger... The nervous system wasn't really understood before the 1800's. Before Edward Hubble, many believed in a static universe. Christian countries have been waiting on the four horsemen of the apocalypse for the universe to end, with numerous countdowns and disappointments. Look up celestial spheres. Science opens up the universe with discovery, something that philosophy fails to do.

CD070788 1 month ago
the assumption with philosophers who think up this paradox is that time dilates when space gets smaller. Of course this assumption is wrong. For every instance space is halved, time is halved also. Of course we have to assume the velocity of the arrow is constant. You can assume it is possible to half space an infinite amount of times, but when you do time equals 0, hence since a moving body is not at rest, the arrow will always have a finite distance to reach it's target. Paradox solved.

I think there are some basic problems with describing this Paradox. Firstly, you assume that you can measure a point in space absolutely. Neither an arrow or a target would be able to occupy a singe measurable point in space. Therefore, there cannot be a half way point to measure. (The more you 'zoom' into an 'edge' of an object, the more difficult it becomes to delineate it from what surrounds it.). Equally, you cannot ever say accurately that the arrow has reached the target.

@SpiderRift That is the assumption made, but it's wrong. The arrow has kinetic energy the instant after your record it's 0 displacement; no matter how small the distance it travels. In that instant the arrow has a finite time it has to reach it's destination before it violates newtons law.

But if a point is infinitely small then there would be more and more space between the point and the tip of the arrow, so it would have to move to reach it.

And the answer to solve this lies in that 1. V=A/D*T. And for V=0 A=0 but because of a downward force of gravity says that A is 9.82 in a downward vector meaning that V must be something. So it has to move. And the other paradox is when you reach halfway you still have halfway left... so the arrow doesn't move at all even if it looks like it hit it's target it haven't which is true at quantum physics.

Just like everything else in nature, time and space are fractals (look that word up) which means infinity can fit in a finite space, just like it was demonstrated. Movement is just a frame-by-frame illusion of an infinite number of parallel realities that ends up creating the effect of time; therefore, time is just how long it takes any kind of movement to take place.

@ronnyboy6o
infinitie parallel universe has the same flaw but only in disguise. If there exist an infinity many universes then there is always parallel universe being added. We have everything and then we add one which makes a new everything. Infinity without assuming it converges to spesific number is still unsolved.
It is just like gravity. We know it is there, but we can not tell why and what it is. But maybe there is still a link between infinity and finity to be discovered;)

@steverock85 Maybe rather than one reality 'added' to the last, it replaces the last. Which also implies the idea of non-locality and time would still be the effect from motion, i.e. the concept of the 'here-and-now' is all that exist & time/location is completely illusory.

You are correct, we do not need to understand concept of infinity to go on with our lives. This is the only way we can see this but it does not solve this paradox.

Might be, kind of like that idea.
But the trick is that in our mind, we freeze the time, and give each observed point a static point in time. Thus observing itself will diverge to infinity while the movement of arrow will converge.
Kind of like the liar paradox. Now who is telling the truth of what is really happening. Also what is distance at all. In math any distance can be broken down to infinty, but yet, the distance it self is finite.

Everything said contradicts this whole theory, "Before it may reach the target it must reach a half way point" To do either the arrow has moved. To reach is to to get to or get as far as in moving, going, traveling, etc. To even consider this as a paradox you dont understand basic physics.

The very basics of math is about magnitute and quanity. You are free to think this is not a paradox but it shows in very simple way how limited that thinking is to descrepe our world when it comes to infinity. We can approx when the value converges to specific number but that is all there is to it. This is seen for example in pythagoras, irrational, series and limits.

To understand what is going on try look at this. Let distance be m and 2^n, n>1 be the division of time of this distance. So we have sum of series that will equal one or:
m/2+m/4+m/8+m/16+ ... +m/2^n = 1 (or almost one...)
You can put "sum 1/(2^n) from 1 to infinity" in input in wolframalpha . com to see what is going on.
The time to travel will not change, nor will the distance. This is more about what time is and what happens if we focus on each step in the way.

The paradox is that there will always be fraction missing that makes m or 1 whole. Kind a like sqrt(2), pi or any irrational number or rational number like 1/3, which can not be repisented as a magnitute in its purest form. ex: sqrt(2) = 1,4142... and 1/3 = 0,33333...

@steverock85 There's no paradox. After time T the arrow reaches the half way. After time 2T the arrow is at the end. There is no fraction missing when time is over. There is no paradox.

iambill3 1 month ago 2
Isaac Newton resolved it mathematically. He used similar reasoning to calculate "instantaneous velocity" meaning velocity measured at a single point. His concept was to take the "change in position" DIVIDED BY "change in time." Zeno neglected to divide by time so he never came up with a mathematical definition of velocity.
Newton generalized the concept to take the DERIVATIVE of a function. Leibniz did it in Germany at about the same time but Newton got the credit.
Skeptic121 1 month ago
@Skeptic121
Yes we can use the derivatie to find the instantaneous velocity, but it does nothing but support this paradox.
If you think this as in term of a straight line with the properties of a real numberline, then you can not get anywere. You can divide the line infinity many times and you can not conclude any limits of this devision.
If time is within the reals, then you can pick any point, no matter how small.
This means there has to be a finite division number in timespace.
steverock85 1 month ago
@steverock85 The concept of limits is the only way to do infinitesimal calculations. It means you can take the smallest non-zero interval you like, but it must be a real number. Give me the real number and I can calculate the distance moved if I know the velocity. Consider y = 1/x Give me the smallest non-zero value of y that you like. I can then calculate the value of x required to give you that value of y, or less. We can't get to zero, but we can get as close as you specify.
Skeptic121 1 month ago
@Skeptic121
You have to be careful when you talk about real numberline as we are talking about irrational numbers as well, how does that work in real life?
Lets consider y=1/x. Let y = speed and 1 = meter and x = seconds. Now as x get closer and closer to zero what will happen? We will break any physic law as we will travel faster than light. y will go to infinity.
On the other hand, if x will go to infinity like in this video, y will be 0... no movement at all.

steverock85 1 month ago
No I disagree. These are NOT the conditions. In what you describe, you SLOW DOWN. Half the way in the same time = half speed = slowing down. Slowing down means that you do not want to reach the goal = point B. If you do not want to reach the point B, then there is no paradox, because you will not reach it by construction! This is then not a paradox. Mathematically, you would reach B at infinity.
The condition is: Same speed. Then it is exactly one hour. Sorry, I meant "hour" not "week".
BuggaUgga 1 month ago
This isn't a paradox its due to an equivocation between mathematics and universal physics. The premises are: Motion is the change in position for an object from point A to point B. There are an infinite number of points between any given points. Therefore motion is impossible because nothing can travel an infinite distance in a finite amount of time because you cannot divide infinity. Instead the problem is that there is a smallest unit of space and therefore there isn't an infinite # of points.

this paradox is assuming you can divide distances smaller than the planck length. You can't actually measure anything smaller than the planck length or time, you will simply warp to the next point, hence movement is possible because its not continuous.

that is called a limit, so let's say you want to walk from point A to point B, and each hour you walk half the distance from your current position to B, then how much would it take you to reach point B? the answer cannot be 0, because in 0 time you wouldn't be there, it cannot be infinite, cause no matter how much time you spend you NEVER reach point B.

@pairot01 But the point is, why does there have to be a minimum amount of time? Aren't there things that take less time than what you said?

@simonbob13 yes,of course,but that's not the point,i set up an example not a phisics law...

@pairot01 "Because it actually DOES travel" You don't need to travel to go move 0 millimeters, do you?

@simonbob13 no,but THIS arrow MOVES

@pairot01
I was never talking about the arrow in the video. I was talking about the planck length.

@simonbob13 yeah,i just figured you weren't talking about the arrow XD
wtf is a plack?

@pairot01 I dunno...the one guy said that planck length was the smallest possible length...
simonbob13 1 month ago
@simonbob13 there's no such thing,you can always continue to divide any length in half, it may be smaller than a micrometer

@pairot01 I know...that's what I've been saying the whole time...
