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
I think maybe you misunderstand what a model is in this context. It’s any way of mapping observations to a theory of how things work. I would say a good model is one that can create useful testable predictions. This tests the accuracy of the model, and it also provides for innovation. You can have a model based on a random sky fairy magically doing stuff and writing a book about it. But that model is untestable, and useless.
Again, define useful/useless? To what end do you create these models?
Again, to understand our observable reality and make predictions.
To what end? What happens when you understand and can make predictions?
