Blade is pairing up the balls taken out with the time steps. But what if Blade instead paired up sets of nine balls with the time steps? Let’s say that she adds 10 balls and removes the first ball in the line, but then changes which set the first ball of every set belongs to to be the set before. e.g. at time step one she adds 10 balls and removes the first (sets are balls 2-10 = set 1); at time step 2 she adds 10 balls and removes the first ball in the line, which is ball 2, and shifts the assignment of the first ball in the newly added set so that it belongs in the first set (sets are balls 3-11 = set 1, balls 12-2 = set 2) etc. At noon, how many sets of nine balls does Blade have? The mechanism is the same, but the answer is different depending on how you pair.

@sourcererseven3858 2 жыл бұрын

Exactly my thinking. If infitiy desn't end, the question "how many balls are in the vase at the end" just doesn't make sense. You can just as well ask "how much is god" and the answer won't be "0 Euro", nor "infinite Yen". It'll be "I've told you every week for a year to leave my sermon and if you come back next week I'll call the cops".

@Tankirb 2 жыл бұрын

see what you just described is Zeno's paradox. The idea is that since you can divide the distance between the beginning in half an infinite number of times you will never reach the destination. lets use your example of the ruler. in the first step we move 6 inches, then in the next step we go 3 inches next we go 1.5 in so on and so forth. in practicality it is (1/2)+(1/4)+(1/8)+(1/16)... you claim that since you can keep moving half the distance you would never reach the end of the ruler. However this is false we can actually prove that (1/2)+(1/4)... is actually equal to 1 here's the mathematical proof (1/2)+(1/4)... = y 2 x (1/2)+(1/4)... = 2y 1+(1/2)+(1/4)... =2y multiplying (1/2)+(1/4)... by 2 results in 1+(1/2)+(1/4)... because (1/2)x2= (2/2) which is 1 and (1/4)x2= (2/4) which is (1/2) and so on and so forth (1+(1/2)+(1/4)...) - ((1/2)+(1/4)...) = 2y - y 1=y and boom we have just proven that (1/2)+(1/4)... is equal to 1 (fun fact a very similar method actually proves that 1=0.999...) if every step on the ruler took the same amount of time then it would take an infinite amount of time to reach the end but by doing something called a supertask we can actually do it in any finite amount of time. lets say we want to walk across the ruler in 1 minute we take the first step through half the ruler in half a minute AKA 30 seconds then we do the second step across 1/4 of the ruler in 1/4 of the time AKA 15 seconds we continue to do this and by the time 1 minute passed we would have crossed the ruler moving at the speed of 1 foot per minute if you pay attention what she was doing is actually a supertask if you don't believe me I would suggest doing your own research into this subject there are many great videos on this subject on this platform

It is not. The paradox arises from the fact you cannot reach infinity via counting with finite numbers. For example, you can have an infinity universe model (current ones are finite though), but it could not be created from finite things, it could however exists ever.

@thatchinaboi1 3 жыл бұрын

Nope. They don't illustrate that a physical infinity is impossible. They illustrate that infinity is not a number or a quantity. And to treat them as a quantity by performing mathematical functions with the concept is to make a silly mistake.

@thatchinaboi1 3 жыл бұрын

We know that Space and Time are physical and real infinites because they are infinitely extended. We know they are infinitely extended not because we can observe it in their entirety, but because we can use a priori deduction to deduce it. Remember, Non Existence can never be. Therefore there can be no Non Existence that can delineate a spatial or temporal finitude to existence as a WHOLE. This a priori truth was pointed out by the great Parmenides, over 2,500 years ago. :)

@sirquixano5985 3 жыл бұрын

Infinity should not be thought of as the largest possible number, but a number so arbitrarily large that we don’t care if something is slightly or even fractionally bigger or small most of the time, and then infinitesimals as the same except 1/infinity, which makes maths and stuff like L’Hopitals make much more sense when working with infinity, as in the paradox, as one of the infinities is “base infinity” and the other is ten times “base infinity”, so you subtract them. Its basically the same idea as Xeno’s arrow, which splits infinitesimal distances over infinitessimals at the same rate, so the arrows move even though theres an infinite amount of subdivisions, its happening in small subdivisions of time that are decreasing at the same rate. It also explains why some infinities are bigger than others, for example, you can take a line out of a plane, but not vice versa, so it would be base infinity vs (base infinity)^2. This explains a lot of paradoxes, as there is technically stuff higher than infinity, we just don’t care most of the time, so we consider it to be some sort of value to high for us to really care about the specifics most of the time. Then again, maybe this is too much of a nonanswer.

Hence you get a contradiction to which either answer gives an incomplete answer.

The problem with the set up here is that the clock doesn't move after the first 9 balls go in. At 18 balls in the vase, 30 seconds is used up and at 45 seconds 27 balls are in the vase. This makes one believe that every 15 seconds 9 balls end up in the vase. Unless you watch very closely from 45-60 seconds when the clock starts dividing its time by 2 for every 9 balls it's impossible to have a "thought experiment" about this paradox. There has to be a better way to start this experiment so it's more user friendly. Also, there are two equal sets of infinity going on here. One set has 90 percent more balls than the other set. Just because you remove one set from the vase doesn't mean there aren't an infinite number of balls still in the vase represented by the set where balls are Not removed at each infinite time stamp. Empty vase? Preposterous!

Hey Nick, what if the reason there is more matter than antimatter is because after both being created they got paired back in a different way such that they annihilate only the "even" matter, leaving behind the "odd" one. Just like the vases in this "paradox", one ends up empty and the otherone ends up full, like our universe. Of course for that to be the case, the universe would have to be infinite and there has to exist a pairing mechanism that results in a full vase (universe). Can that be a theory?

A more formal explanation: you're describing infinite sequences of sets of natural numbers. For the first example, S0 = {} (the empty set; the vase starts empty). S1 = {1..9}. S2 = {1..9, 11..19}, etc. We can say that this sequence of sets "converges" if, for every natural number, it eventually settles down and decides whether it's in the set or not. That is, Sn converges to S' if for all natural numbers X, there's some N such that (X is in S(M) if and only if X is in S') for all M > N. When we talk about "the contents of the vase at noon", we're really talking about the set to which the contents of the vase converges. In the first example, for all X, X has decided whether it's in the vase or not by timestamp X/10 + 1. After that point, it will never change its mind. So, the first sequence converges to the set of all natural numbers not divisible by 10, which is an infinite set, so we say the vase "has an infinite number of balls" for short. In the second example, for all X, X will decide that its out of the set as of timestamp X+1. After that point, it will never change its mind. So, the second sequence converges to the empty set, which is... uh, empty, so we say the vase has zero balls in it.

The problem comes from applying the word 'all' in 'pairing all elements of an infinite set'. 'All' or 'every' become semantically nonsensical when applied to infinity because you can't exhaust infinity.

Pairing does not require exhaustion. There are plenty of non paradoxical results that can be derived that involve a constructive pairing between two infinite sets.

Challenge Question: You are in a starship in orbit around the sun. You desire gravity but spinning makes you sick . You decide to decrease your orbital speed until you feel a 1g pull from the sun. To maintain your distance and not crash into the sun as you slow down you use a giant solar sail to to provide the needed "lift". Where would your balance point be? How big a sail would be needed for your ship? I assume you could generate a graph of safe speeds/sail size to give you a region of conditions that you would feel normal gravity toward the sun. Or in other words, is it possible to balance on beams of light to keep from being vaporized in a fiery death?

It's still (+10n-n)=(+9n) at each step, so it doesn't really matter how many steps you take, the final result is still 9n, which is +infinite at the limit. As you said, what the second method does is creating a 1:1 correspondence between the - removed - balls and the number of time steps. The second method has completely forgone counting balls, even if it could have been possible to do it, exactly as it has been done in the first one by counting 9 balls for each step. In the end, the two methods are exactly the same: the only difference is our attention is focused on two different things.

Exactly. Please scroll up and read the comment I made on November 11. I work out the mathematics. What is really annoying here is that there is so much misinformation in the world because somebody says something, somebody else hears it, tells it to somebody else, and it spreads to the whole world. Matt Parker (his youtube channel is Stand-up maths) states a slightly altered version of the problem, and his conclusion is that the box is empty, which is absolutely ludicrous. (Please check out my comment on his video about it. He posted his video on October 31. I work out the mathematics there also. Within the video, he describes adding and removing ping pong balls to a box in a specific manner). I wish people everywhere would get the word out to correct this. The Ross-Littlewood paradox, as I show in my comment, is nothing more that a modified version of a divergent series problem, or the way Matt Parker stated it, a conditionally convergent series problem. And yet, because the problem was first described decades ago by a well known and respected mathematician, people automatically (and blindly) think it must be true, even mathematicians and philosophers of today, which completely dumbfounds me. Wikipedia has an article about it that I read quickly last night, and in it they make a couple of ABSOLUTELY nonsensical statements regarding the problem as described.

The concept of infinity is fascinating I always had the thought in my mind that if infinity and infinitesimal behave differently rules, why is the world so predictable? This question made me question myself so much I took physics at my university. Eventually, I realized infinity and infinitesimal in their full glory are just concepts and do not physically contribute to the world[I am pretty sure I framed this sentence so bad I seem a lunatic now]. Like we cannot have time smaller than Planck's time, cannot have speed more than the speed of light, cannot have accuracy beyond the Heisenberg principle. Every place where one could imagine bringing an infinite count or an infinitesimal count/accuracy, there is some rule of physics waiting to disappoint your idea. To me, this seems to make the world predictable. I mean if the behavior of infinitesimal silicon atoms(yes, they are not. I'm just saying if they were) were different from time to time, I would not be sure if this was the exact message you were seeing. If neurons behaved at infinitesimal accuracy, I would not be sure I could control my feelings in front of my crush. And while some say it would have been great if there was one physical non-barrier to infinity; the idea that things are normalized, countable, quantized, discrete, understandable, fascinating really helps me sleep at night.

Step 3, add 21-29 and change the 3 to 30, and so on. How many balls are there at the end? Well, if you claim that ball n is in the vase at the end, I will respond that ball n had a 0 drawn on it at step n, so that ball is no longer labeled n. So, we never removed any balls yet it can be argued that the vase ends up empty.

Treat Infinity as a Variable, like x. But ALSO treat Infinity as the same number in all your equations. Granted the number is extraordinarily large but the same number, like you would treat x as the same number in all equations. Add 10 and Subtract 1 an infinite amount of times (10 -1)*oo 9*oo 9*oo is not oo. 9*oo is Nine times Infinity In your first case, you pour out 9 times Infinity and Blades vase should have the same number of balls, 9*oo, so she shouldn't really run out before you do. You mention a one-to-one correspondence. Yes oo's used in different equations should have a one-to-one correspondence. i.e. They should be equal. All counting numbers is oo. All counting numbers minus the first hundred is oo-100. x = oo y = oo - 100 Yes, y < x. Treat infinity like a Variable and combine equations and you have y = x - 100, so y is 100 less than x. The two sets are not a one-to-one corresponded since the Infinity in the first set is not equal to Infinity in the second set. All counting numbers is x = oo All even counting numbers is e = oo/2 Treat oo like a Variable and combine equations: e=x/2 When treating oo like a Variable, you can continue to apply the "usual laws of arithmetic". Many of the oo equations that I've experienced in college have a condition like "as x goes to infinity" and when you combine two equations like that, you may find that you end up with a finite number. Example: Limit as x -> oo of x is oo Limit as x -> oo of 1/x is 0 Combine the two: Limit as x -> oo of x * 1/x is x/x which is 1. I have not encountered any equations where the oo cannot be treated as the same Variable. Of course if a variable goes to Infinity at a different rate, then include that rate in our equation to make Infinity the same. I truly wish that the usual laws of arithmetic included treating Infinity as the same variable; big, but equal.

No it isn't. A veridical paradox is one where a truth seems untrue but is, in fact, true. This paradox arises from the manipulation of the infinite under application of finite logic and finite processes, resulting in contradiction. There's nothing "true" about the setup or the two contradictory results of the setup, regardless of the (arbitrary) rules of Transfinite Set Theory.
