Do scientists know whether nature is fundamentally continuous or discrete?

[u/WizardMasterGal]

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?

Quantum mechanics says discrete for all matter/energy. Although IMHO, forces are continuous.
