Does he actually have a point?

He's completely right.

>>8791513
No. For one he ascribes some strange significance to a completely arbitrary length scale.

>>8792031
He's not transfixed on some particular value. Any given value past the materialistically documentable works.

>>8792178
He's fixated on the Planck volume, an arbitrary length scale.

>>8791513
link to video?

>>8792265
It's not a specific fixation. It's just an example to provide a likely upper bound on what we can do.

>>8792600
He's used it as an upper bound for the number of things you can have in the universe (approximately) since, as far as he's concerned, anything else won't have physical meaning. He's said this a couple of times and it's wrong:
>Planck units are useful, but are in no way special

You could redefine them in some arbitrary way to make the Planck volume either smaller or larger.

>>8792031
It's not his usage of the Planck scale that's really weird, it's _how_ he assigns significance to it.

His reasoning is that a number isn't actually a number unless there is a (theoretical) physical representation of it via a pile of N sticks.

It seems silly to me that the level of abstraction that lets you talk about absurdly large theoretical physical operations on the level of piles of 10^100 "objects" likely no larger than an atom is okay, but the abstraction of
>let's say every stick represents TWO sticks
is too much.

>>8792616
ok, does that make the argument wrong?

>>8791513
Yah :)

>>8793115
I mean this guy makes a good point, say you have N "Planck sized" objects why can't you just say that each object represents 2 rather than 1?

Too abstract and not based in reality apparently

lol how the fuck did this brainlet graduate

So what's the actual significance that Wildberger gets from not acknowledging the existence of numbers larger than some value? Seems like it wouldn't change anything about current mathematics except for getting to sometimes say "oh this is not a *real* number lol"
