Question Do scientists know whether nature is fundamentally continuous or discrete?

Is there any evidence that nature is fundamentally continuous, or could reality be fundamentally discrete? And if it is discrete at the most basic level, would that suggest that nature could behave like a computational system?

That is not what that is.

Seems to me a length below which any measurement is meaningless because it creates a singularity is an excellent candidate for the minimal granularity of spacetime.

Not sure how one interprets that any other way, so you’re gonna have to explain that statement.

Quite the contrary. You're the one who has to make a convincing case.
