This assumes hardcore causality though. We already know that prediction is epistemically not always possible, which means that for certain processes we predict outcomes in terms of probability. This is an issue for things such as complex systems, chaos theory and quantum indeterminancy. I was not primarily suggesting anything about things that do not affect our observations but things not being relevant for our observations as they fall within the scope of probabilities. We'd never notice the absence of simulation of such objects. — Benkei
Second, I don't think it's about "things" either but about qualities. How does the quality "weight" influence lenght and width of an object? How does smell do that? What I'm suggesting is that when I look at something from a distance, the simulation would not have to render weight or smell. The tree falling in the forest where there's no one to hear it, doesn't need to make a sound. It does not need to render completely anything happening beyond my field of observation. In more general terms, anything outside my reference frame doesn't need to be fully rendered. — Benkei
Try to come up with a quality you can both demonstrate to exist and that doesn't affect our observations in any way. — Qmeri
It doesn't actually assume hardcore causality since the uncertainty of a probability based world requires even more processing power. — Qmeri
The probability based quantum world of ours is actually a very good argument against us living in a simulation since a probability based world where almost infinite number of possible quantum states affect the next possible quantum states and their probability distribution is almost infinitely complex to calculate. Classical mechanics require almost infinitely less processing power. — Qmeri
I already did! Weight is irrelevant when I'm not holding it. So it doesn't need to render that quality at that time. Just like a computer that doesn't render anything beyond a horizon in an fps. It's the same concept. — Benkei
Classical mechanics is good enough most of the time so a simulation would use that and relativity to describe the macro world most of the time — Benkei
another example, the movement of planets can be described accurately without knowing how they were formed, what they consist of, how many meteors struck it and whether it supports life or not. I can simulate the movement of planets, without having simulated the planet's history. — Benkei
I'm only superficially familiar with Simulated World theories, and mostly with those of Tegmark's Mathematical Universe and the Matrix movie. But I note that most of those theories seem to assume that the processor is a space-time machine limited by the laws of physics. But what if the processor actually creates Space-Time? I'm referring to Donald Hoffman's concept of space-time as the interface of our reality. In that case, physical objects are symbols (icons on a screen) referring to metaphysical Forms. If so, the hypothetical simulated worlds would be simulations within a simulation.Therefore if we don't specify our own processes and prove that they are somehow necessarily hugely more represented in simulated worlds than in non-simulated worlds, we most likely live in a non-simulated world. Any thoughts? — Qmeri
This is because of something I call processor efficiency. I define it as the percentage of real time speed a processor can simulate itself in real time. We can see in practice that processors we have are very inefficient and many more "natural processes" that make up the processor are needed to simulate one of those processes. And a processor that can simulate its processes faster than it itself is, would cause absurdity since the processor it simulates could simulate a processor even faster etc... causing an infinitely fast processor. — Qmeri
I don't understand. Why does a simulation processor need to simulate itself? — TheMadFool
