Hey! Nice to hear from you from this alternative account. I am happy to see that you are still around.
Maybe one thing you could do, instead of trying to read the entire paper, would be to focus on the introduction where we present the problem we are trying to solve and explain why they are important for our field. What do you think?
... good morning then again , i'd say ...
if every physical question can be answered by the theory, then the theory is said to be complete ...
The Standard Model is not complete. Even when Jay Wacker says that the Standard Model of the 1990s is complete, I disagree with the statement. There are still many quantities of the Standard Model of the 1990s that have not been measured, and that we won't be able to measure before at least 50 years. So... until one gets there, there is still work to do, IMO.
It's about probability is it , no one can really say it's "like that" [...]
In particle physics, every theory prediction comes with an error bar, so that the central value is what it is, but it won't be shocking if the right answer would be elsewhere in the error bar.
I hope I clarified a little bit :)
