athmwiji: if I understood correctly, you said that the concept of the physical world arises from our subjective experiences, and even if we explain that consistently, there still remain subjective experiences which we can’t. We could for example imagine a simulated world in which everyone has silicon-based brains, including, at first sight, you, but in the real world you’re still a human with a traditional flesh-based brain. There would be no physics then, which you could use to explain your headache with in-world mechanisms.
But without assuming that you’re in such a special position in the world, you just have to explain why the other seemingly conscious beings (including AIs made by us) argue that they must have special subjective experiences which aren’t explainable by the objective physics. (In fact, the whole thought process is explainable.) I think it’s the same as free will...
Tiiba: no, the Martians wouldn’t be able to contradict our math, as it’s a model about what’s happening around us, of the things we perceive. They wouldn’t have different anticipations of real-world facts, but they would have different concepts, as their “hardware” differs from us, and so do their models. If our world would consist of fluid, seemingly infinitely divisible things, I don’t think we would understand prime numbers at all… (As quantum mechanics doesn’t seem to be intuitive to us.)
So I can imagine another math in which 2+2=5 is not obviously false, but needs a long proof and complicated equations...
