Is the fundamental nature of reality discrete or a continuum?

[Hayabusa Rider]

This mathy smart guy HATES people who think the fundamental nature of reality is discrete:

His mathy knowledge is beyond my comprehension to critique.

I liked my question better.

What's in between the "grains"?

I used fewer words to make the point

I think I would have asked the question like this.

"Is the continuum of reality ultimately discreet, or is the limit of our intellect which causes it to appear that way?"

In other words we define the limit of what is comprehensible as the Planck scale. Is that an absolute point where physics breaks down or is it merely our inability to grasp what comes next?

Do the "cracks" have qualities which are fundamentally beyond our grasp?

Do they make Plank graph paper?

Thought I'd bump this old topic because there was a contest in 2011 to answer this question!

No answers, of course, but lots of very interesting papers. Anyone who had pondered over this question will enjoy this.
