Is the universe discrete or continuous?

What proof is there that the universe is discrete and what proof is there that the universe is continuous?

You can never know if the universe is discrete for certain since even if it appears so there may still be some undetectable phenomena you are unaware of.

You can never find evidence to suggest the universe is continuous as there can never be a scientific instrument capable of infinite accuracy.

what meaning is there in that?  its just demonstrating that we can come up with conjectures that withstand repeated tests, as many as have been performed up until now anyway.  maybe its useful because with it we tend to produce technology which is both consistent with and based on our observations and apparently good for us?  what is "useful", what is "good"?  there is so much assumption in this.  we might assume correctly, but it is assumption nonetheless.
