It doesn't. It's a distinct SEQUENCE of events, not a set without order.
Set theory doesn't apply. It's just another example of set theorists
trying to claim that everything falls under set theory. This experimant
obviously does not. Set theory is incapable of handling the concept of
sequence in a well-defined way over such a set.

No, set theory confuses the issue with its concentration on omega. There
is no such distinct size of the finite naturals. The infinite iterations
are all compressed to a point in this experiment, and since those
operations are a combination of additions and subtractions, set
theorists feel entitled to rearrange the events any way that gets them
their magical results. It's pitiful.

I don't disagree with that. After the removal of every such ball before
noon, nine times as many balls remain as have been removed. That is true
for every moment before noon. The conclusion as to what happens AT noon
either does, or doesn't, have to do with this fact.

If we start with a vase full of any number of balls, and remove one ball
at each of these -1/2^n times, then it becomes empty at noon, or before
if the number of balls is finite. There is no argument about that.
However, in this case, no balls is removed without ten more being
inserted, so the vase cannot become empty, despite set theoretical
shenanigans.

That is not a number.

Because, during the period that the balls are being removed none are
being inserted.

Then you are inserting balls one at a time, and removing them as you
insert the next. What does that have to do with the original problem?

Your take on logic is very, shall we say, provincial.

BEFORE you get an infinite value. Learn to read.

That is correct. That's one way to get an infinite value.

It was in remedial reading class, when you fell asleep.
