I genuinely was not intending to 'bait' you. You presented an argument saying your knowledge of the subject is more robust than the experts who refereed the paper. Since I am not an expert in the subject and am curious about learning more, I was asking you to guide me in that process with your experience.
I felt that your arguments suggesting that the author is presenting an inconsistent logical proof were not well defended and so I asked for clarification on the points you raised. I am still unclear what you are saying in this statement:
These are the four criteria that establish how a computational theory is logically defined as a formal system, not an argument. The author makes this clear in addressing the notation being used:
After that paragraph the author uses several very specific examples in modern physics theory describing how the findings apply starting with the paragraph:
Again, I am trying to approach the authors bold claims with skepticism and scrutiny, not argue with you. But you have to be a little more humble, the paper wasn't published in order to convince you. Just because you weren't convinced doesn't mean that the proof is invalid.
Actually, F_QG is itself an assumption which isn’t backed up. See the paragraph before the one you quote when defining it. The beauty of axioms is that we can assume whatever we want but we need to either show nothing goes underneath it (eg Peano axioms) or have a very compelling case to make them (eg non-Euclidean geometry like parallel lines meet at infinity). This is a metasumary of some similar research at best. It’s not a proof in the way you think it is. Just because you don’t understand what you’re responding to doesn’t mean you’re right.
Thanks for responding! I never meant to claim that I am right. The whole purpose I am engaged in here is that I do not understand the proof at all and am trying to understand it better.
Here is where F_QG is introduced in the proof:
Is this not just saying that it is the existing theories (string theory, LQG, etc.) that are assuming gravity takes the form of a formal computational system? And so, F_QG as it is defined above is how any formal computational system is logically constructed, as in it has to have those three components in order to logically be a formal computational system?
I am not a logician and do not understand what a first-order language is, or closed sentences or all those logic terms in the definition of notation. However, is F_QG in this case not just logically how any theory would need to be constructed in order to logically be a formal computational system? Is there an assumption being made here with regard to those three components in how formal systems are logically constructed?
