Say, let’s admit consciousness is the result of a physical process.
Then say this process only goes “forward” when our time coordinate increases. Just like an egg gets cooked when it’s temperature coordinate increases, but it doesn’t get more or less cooked when it’s temperature coordinate decreases.
This would mean that going back in time doesn’t result in any perceptible change, since your consciousness hasn’t evolved from it’s “former” state.
Thus making it possible for us to be travelling through plenty of dimensions in varied directions, only ever experiencing the brief times when you happen to be moving in increasing time. Or whatever combination of movement along varied dimensions makes it possible for you to be conscious.
TLDR: i need to take shorter showers
We don’t have proof that consciousness is the result of a physical process. But there’s no reason to think it isn’t. You can make up anything and say it’s unknowable, and nobody can prove this false; but it’s pretty much useless. Sure you can stick with ‘I think therefore I am’ as the only knowable thing, but it won’t get you very far. The physical world as science has self-consistently explained has been shown to be very practical, specifically with prediction of observation. Consciousness seems different, but there’s no real reason to assume it is.
Thing is that science cannot prove matter is prior either, yet that is taken as the core assumption that all other assumptions must align to.
This is the scientific version of Christians saying “god is real, says so in the bible, and because bible was written by god, it must be true”.
Science can’t prove anything. It seeks to build comprehensive models that agree with observations by disproving those that don’t. It is specifically built in a way that uses predictions based on theory and then tests them. This process is used to avoid making useless and unknowable additions. That, and its inherent nature to question everything, is what makes it fundamentally different from religeon. However, it is based on an assumption that the universe makes sense as a physical construct. And that is because there is no other useful starting point. You can try to build a model of the universe based on any gibberish of feelings, but it isn’t useful in any way.
