Isn't the key axiom - preservation of information - a presupposition, and not a formally evidenced law? As best I can tell, it's mostly been assumed as a required premise for a larger axiom - the eternality of matter.
- Strilanc 4y agoHere's a relevant blog post: https://scottaaronson.blog/?p=3327 https://scottaaronson.blog/?p=3327 'Is “information is physical” contentful?' In quantum mechanics, breaking unitarity (which implies conservation of information) is akin to breaking the rule in statistics that probabilities have to add up to 100%. You get things like a 300% chance of rain or a 90% chance of [null reference exception]. It's hard to overstate how deep down it is and how many things depend on it.
