Lex, I have also struggled with the concept of infinity. At a young age, 2 years old I would get extreme anxiety and take off running when I thought about "forever" As I got older, I realized that time is a construct that we are experiencing as beings in the 3rd dimension. And that our human brains cannot fathom what the 4th dimension is like, just how a 2D being can't imagine 3D.

Man, as a kid I would lie in bed and think about like, what it meant to live in "heaven, *forever* " and when I thought about the longest period of time I could imagine, then multiply it, forever... and in a moment I could almost "conceive" what infinite meant, and my heart would drop in my chest and I would jolt up in my bed like "fuck, I dont wanna think about that again, anymore." I dunno, just something that stuck with me when I was a small kid.

'Ghosts of Departed Quantities' - nicking that, title of my first solo album.

I like Aristotles answer to this. The distinction between potential and actual infinity. Potential infinities exist. This is the kind we find in mathematics. The mental process is non-terminating. Take adding numbers no matter how big you can get you can always add 1 and get something bigger without any end in sight. However, notice whatever number you get to it is something specific, finite quantity, and this is the actual. Actual infinities don't exist, either in mental process nor as a thing in reality. One of the implicit laws of his is law of identity, every thing you come to know is something specific that has identity, it can't have that identity while being something else contra to that identity at the same time in the same respect. To be specific is to have a unique set of finite properties. Because if it didn't, how would we know if it's unique or not? The properties would actually go on without end. So now let's take actual infinity. Let's say it has a specific identity, but if it's actual infinite it has no finite set of things, therefore it can't be uniquely identified. Therefore it has no identity. Therefore it doesn't exist. Also don't mistake actual infinity for eternal. These are not the same thing.

The real question is: Is mathematics manufactured for our consensuses to make sense of numbers? Infinity doesnt work in our brains comprehension of math. Why did we choose to recognize numbers in 10's 100's 1,000's We could have learned it in evens, odds, or maybe left or right. We are training ourselves to think a certain way, then we dont understand how to think about a concept of infinity, but infinity never made sense to me.

It’s like the null pointer exception

This is an issue that is close to the heart of many of the really greats in Physics(1890's). The problem at the time was believed to be an ontological problem and is now understood to be a epistimological problem. There is a beautiful book by Erret Bishop that rewrites much of useful mathematics into terms that allow any proof to be constructed. The issue is largely moot with Goedel's theory, which shows that we largely misunderstood mathematics and logic up until that point.

Infinity is a direction, not a destination. Saying "infinity" isn't real is like saying "backwards" isn't real.

Infinity is impractical and should never be used as a variable in math equations. The number of atoms in the universe or some other ungodly large number should be used instead. At the heart of it, infinity is not a number, but the never ending nature of numbers.

If I remember my analysis book correctly, the point of infinity is to make good approximations of quantities that wouldn't be as easily done without it (if at all).

the "infinity" within Calculus that "works" works only in conjunction with the infinitesimal derivative in the definition of the limit - which itself is not a literal value, but rather hand-wavy method based on intuition. so it's not fair to use Calculus as a case-in-point for where mathematical infinities comply with the real world. as it should be understood, all of mathematics is as abstract as its infinities, and so the goal posts for what is and isn't consistent is relative to the system its defined in.

I've been thinking about this recently... except I think the counting numbers are fake, too. The only numbers we should accept are the handful of constants in geometry and physics: pi, phi, e, etc.

A lot of people feel uncomfortable about infinity because they have received bad/incomplete teaching about subsets like real numbers/calculus. It has nothing to do with infinity itself. I have heard people saying stuff like "you can arrive to all sorts of contradictions if you assume infinity" which is totally wrong for example. We learn about real numbers without a construction, like Dedekind cuts, which might be reasonable but the result is that we feel the uncomfortable feeling that something is not completely explained there. I guess a lot of people assume there is no further explanation and reals are just not well defined. Of course there are those who know and yet propose we should do things differently.

I immediately agreed with Cantor's diagonalization proof. Then I realized I didn't understand it, so I didn't believe it. Then I understood it and didn't believe it. Then I understood it and believed it. But I remain nevertheless unconvinced.

Why are you uncomfortable with it?

1 can be an infinite number if you take infinite as immeasurable. If you had a single object in space it would be immeasurable because you need something else to define it. It can't count itself and so is immeasurable. It's relative. I think if the universe as being both finite and infinite. Finite because there is a definite amount of stuff in it. And infinite because it will always be at least one bigger than can be measured or counted. Like a string of pearls. Take one pearl and use it to count all the others because you need one thing to count another. At the end the pearl you used has nothing left to count itself and so the actual number of pearls is unknowable. Like the uncertainty principal there will always be some information that is ultimately unknowable.

There is a hypothetical finite highest countable number for any sentient being to count to, before they expend all energy available to them in the universe.

if infinity is fake, what is at the end?

I'm 1:09 into this video... never heard of the concept of 'infinity being fake'..... and upon hearing the qualifiers... I 100% believe infinity is fake. But I also believe in the concept of robust mathematical tools. Infinity just happens to be like this super amazing substitute for "we dont have the logic to understand the deepness of this yet"

Like they said in the video, in Newton's calculus the concept of infinity (both the infinitely large and the infinitely small) is not super precisely defined (later on mathematicians did try to precisely define calculus, and all of that is encapsulated in a branch of math that we call "mathematical analysis"), but it is a tool we can use to effectively do calculus and specifically calculate limits and derivatives and integrals. In that version of calculus, in my opinion, infinity simply represents the idea of observing what happens to certain situations when numbers get very small or very large. Is that such a foreign concept in real life? Personally, I don't think it is. I don't see why we're having philosophical arguments that lead nowhere. Calculus clearly works... and actually describes a lot of real life phenomenon very accurately.. to me that settles any sort of philosophical debate.

I've always thought that there is no such thing as a realized infinity. The potential for infinity exists, yes, theoretically the whole numbers are infinite, but you're not going to count to infinity just to prove it, because you'd be counting forever... Infinity exists as an idea of what something potentially is, but can never be realized.

I have the same opinion. There are a lot of contradictory things in the universe, wave/particle duality, uncertaintly principle, quantum entanglement to name a few.

I also like Roger Penrose's ideas about a cyclical universe and also the idea that universes are born and re-born and evolve, which makes sense, just not testable. :)

Infinity is irrational.

Lex - *sarcastically* Bro i'm basically an expert Me - Sounds about right

Infinity and zero have a lot in common, lets get rid of both of them!!

I mean.. when you Stop counting??

Finitism should be taken seriously, because: no infinite set of anything has been observed in the physical universe; infinites are only known to exist as abstract ideas. And we do get into trouble when expecting to have an actual set of infinite things in physical existence, and theoretical physics of the origins of the universe is a good example. Various multiverse theories posit an infinite regression of prior events into the past. Logic itself gets violated, for if there are an infinite set of prior events, how could the present even come into being?

Maybe the idea of finity is because of the end? At leat that is our conecpt of things. Endings and all that's our conception and only that of something inhuman. Infinity is the same. How can we know if things have no end? It's a philosophical question after all. And it's not bad. I guess.

Haha “lex” we’re “1” it’s “xeno” I would love to speak in depth about this.

Infinity is possible outside of this universe.

Maybe it’s double slit’ish. Numbers don’t exist until they are observed

If we lived in an infinite universe we could not exist, as any part of infinity can be divisible/multiplied by infinite. This would therefore provide no reference point for reality or relativity to exist in. There would be no reference scale. Existence could be infinitely small and infinitely large at the same time. That is my opinion on the matter and I do not think you need to be a doctorate in math's or physics to work that out.

I'd love to be worthy to be on Lex's podcast, I don't think he has vacancies for armchair enthusiast about everything that's written nothing!

What this comes down to is, while 1/3 + 1/3 + 1/3 = 1, Mathematicians have decided to accept that .3 repeating + .3 repeating + .3 repeating also equals 1. The problem is that it is not. There are no amount of 3s you can add together to make it true, but in the limit, WE have decided to ACCEPT that it is TRUE because it allows Mathematicians to invent useful tools that Engineers & Scientists can then use to make excellent approximations. Because the Large infinity can be used to fool you that this is True (again, it is not, we have just decided to state that it is true to go from there to invent useful mathematics), the Small infinity that is more understandable to the human mind is Zero. Just like 1/3 + 1/3 + 1/3 = 1, we can show Mathematically, that 1/3 * 1/3 * 1/3 * 1/3 * .... (infinitely times) is equal to 0 (BY DEFINITION). If you think what this is saying, that you can take 1/3rd of a piece of pie, cut it into 3rds, and then do this again, and again, and again, and again, ..., then Mathematically, you will end up with ZERO pie to eat. This type of infinity mathematics 'tool' can be used to make 2 full pies when you only started with 1 pie - and is a famous mathematics problem. Infinity isn't real, but invoking it allows us to do real useful calculations. Once you accept the religion of Infinity, you then get introduced to the Imaginary World of (i) - which I personally think is far more understandable to humans once you grasp that a 'number' can have more than 1 part to it to represent that there are numbers both above and below the numberline.

This is a common misconception, the 1/3=.3333... is just an artifact of notation. There's no sense in which the .333... needs to end, it's just an artifact of converting 1/3 to decimal notation. In actuality it's as simple as 1/3+1/3+1/3=3/3=1; nothing left over. This is especially true since our choice of a decimal number system is arbitrary. If we used a ternary number system instead, the "decimal" expansion of 1/3 would simply be 0.1; 2/3 would be 0.2, and 3/3 would be the usual 1; no repeating decimals.

The arguments that support infinity break down if you only think about it for more than one second. For instance, the argument that you can always add one to any finite number, sure you can do this but nomatter how many times you do this the result will still be a finite number. And if you say "but what if you do this an infinite amount of times", than you're supposing the presupposition of what you're trying to conclude. It's an obvious fallacy in logical thinking. The argument that you can always divide a number is the exact same fallacy, because the result will always be finite unless you presuppose that you can do this an infinite amount of times.
