we see only what our eyes allow us to see.
If we are a simulation we could be a simulation in a universe with completely different laws that aren't so goofy, i.e. where what the beings see in that universe is exactly that which is there.
Maybe our laws are so freaky because in order to get a simulation as complicated as ours running, the beings in the real universe had to modify the laws to cram them into the simulation. Maybe this is why things are quantized, i.e pixelated.
