There is a lot in physics that is unresolved—but this is (mostly) because it is untestable.physics theory becoming more like the ramblings of some unknown sufi sect-think light cone beings, super strings, dark matter etc- without much actual physical evidence to begin with, physics the 'mother' of all sciences does not have a cohesive testable theory in place for the question of where did it all come from, that's what I mainly meant by all knowledge beginning with fiat. not that it practically matters..
The stuff that is testable has been proven beyond a doubt. We know that relativity is true, and GPS systems actually rely on this knowledge. Quantum mechanics, though admittedly pretty strange, has been thoroughly tested and is responsible for making the machine you are using right now work. This is why it does matter, practically—when physics works, it makes useful technologies work.
Relativity and QM work for their domains—the very large and the very small. But there's stuff even larger, and even smaller, that still needs testing, and we're not really sure how to connect these domains. But our knowledge is improving every day. Certainly you'd agree we know more today about physics than we did 50 years ago, yes?
Um. I've been writing about my "take" on morals for pretty much this whole thread!what's your take on morals btw, I mean don't they have too many fiats for you to believe in:?
