Has this been actually proven? I remember multiple experiments trying to prove the opposite - both effectively a discrete-like and a grid-like universe. Wolfram for example has some ideas about discrete graphs https://writings.stephenwolfram.com/2020/04/finally-we-may-h...
Also I have no clue how anyone could assert that the universe being "continuous" (whatever that means) could be casually claimed by anyone to have any link to our universe being "a simulation" (whatever that means) or not.
