Actually, there does seem to be a pixel to reality and existence according to physics, the Planck Length, and the guy (Max Planck) came up with it around the turn of the 20th century, from the math of observing the behavior of light in matter glowing from heat, aka black body radiation. He was also able to deduce Planck Time and Planck Energy.
We can’t see it, though, it’s smaller to a proton than a proton is to us.

I can see it. I squinted.
And notably, Plank really wanted to be wrong. He didn’t want that to be true, it was just a crutch to make the math work out.
