Is spacetime discrete or continuous? (ie is there an end to 'smallness' or is reality infinitely divisible?)

I think this is the smallest unit which you could divide spacetime into:

*the wiki article says it's not necessarily the smallest unit, but I personally disagree

This

the universe is isomorphic to $\mathbb{Z}^3$ with adjacent distances of Planck lengths (in the category of metric graphs).

Indeed, ƒ(space)=(?space)^?

Planck length is just the smallest MEASURABLE distance

It is continuous.

>Planck length

Is not the same as spacetime being discrete at all.
