Full Idea
One theory is that space is made up of dimensionless points, but physical processes cannot take place in regions of less than a certain size.
Gist of Idea
Maybe space has points, but processes always need regions with a size

A Reaction
Thinkers in sympathy with verificationism presumably won't like this, and may prefer Feynman's view.
