Explanations are paintings or drawings. If in the future we somehow lived inside a computer simulation where objects popped into existence from nowhere and then dissappeared or where we could walk on water if we said a magic formula and any other extravagant miraculous phenomena existed, then we would create a science and a description and explanations of cause and effect based on this. So the science or explanations (the causes and effects, the organizing principles etc.) would be a function of the universe we were observing. Change the rules of the universe and the science will change. Extrapolate this to the oddest and most creative combinations of phenomena we could design in the simulator and you would have a Science that would become an Art, a design, an invention, arbitrary with no intrinsic truth other than we are locked inside that particular universe through the simulation. Now imagine that we are really living inside a simulator where a god or an alien race is designing the reality we observe and hence our Science. In this case isn't science just a painting, an art form ? What difference than does it make if we are inside a simulator or if this is the bare reality, isn't it just a quirk combination of elements, cause and effects, just like any quirk Painting (like the more abstract paintings) ? Reality/physics/universe could be (in a simulator) or could have been (in other possible universes) anything imaginable, hence even science is at the most fundamental level truly Arbitrary. In this sense, seen from a far enough angle everything is just an Art form, Art is Science.
