There goes my solution for Zeno's paradox, which is before you can get all the way somewhere,

you have to get halfway there and before you can get halfway, you have to get a quarter

of the way there and therefore you'll never get there.

One way to get past that is to say even a series of infinite things can have a finite

sum.

Just run the infinite series and sum it and we learn pretty early on that converges.

But another thought I had was that you have to cover a minimum distance, a plank length

and therefore you will get there.

It's a finite series of steps, but you're saying we just don't know it.

So if the laws of physics say that we can cover one meter in a certain time period, then

that's exactly what we'll do.

And our current understanding of the laws of physics say precisely that.

So Zeno's paradox is resolved simply by saying that we can cover this space in this amount

of time.

It's silent on whether or not space is infinitely divisible when someone asks you, is

space infinitely divisible?

Then I would say yes it is and they might turn around and say how do you know?

And I would say general relativity.

How do I know that's true?

I don't know that it's true.

However, it is the best explanation that we presently have of space time.

And then they might get into a discussion about well, if it's infinitely divisible, then
