Fun fact - as best we know, it's fundamentally impossible to know if space or time is actually continuous or discrete.
We've known about the limitation in space for a while with the Plank length, and a similar limitation in time was discovered a year or two ago.
So while we have successful models for the universe that rely on the notion of continuous spacetime, our measurable version of it effectively has a minimum pixel size beyond which we fundamentally cannot get any more detail.
Fit the first time the other year I saw a psychics paper that actually presumed discrete spacetime based on simulation theory, which was pretty funny. I don't think the paper is that interesting beyond that aspect, but maybe you'll enjoy it given the presumption of discreteness: https://www.nature.com/articles/s41598-020-76301-0
