Thanks for tagging me. That was an interesting read.

I'm not sure if you have a specific question. I use the equations of quantum physics daily, but just as a way to make tangible predictions on the observables of condensed matter that I am interested in. The concept of time there is in its simplest and most widely used form. I don't even do anything relativistic, even though the particles that I study can formally be described by the Dirac equation, I mostly use the time-independent Schrodinger equation for everything.

Very down to earth. No metaphysical thinking, just use the probabilistic nature of the equations to make predictions that can be measured.

I usually don't think about the metaphysical aspects of it all. I haven't read a book that ponders the nature of our reality in a long time. Funny thing, though, is that I could only read them when they were written by what I considered a "real" physicist. If it were just someone who was good at thinking, but unable to grasp the equations, I would de facto discard it. The trigger that made me stop reading these kinds of books was when I was focusing on free will, and my conclusion from reading the books was that we don't have free will. It kinda made me depressed and annoying to talk to, as most people want to believe in free will. So, one day, I just decided that free will must exist, as a postulate, and it has made my life easier. But that's also probably why I just use the equations as tools now and don't think much about Everett's many-world interpretation, etc.

I'm rambling, but all this to say I don't have neither the qualifications nor a desire to go much beyond a similar approach towards the nature of time.

Still very interesting to read about it, but I don't look for it anymore.

It's a bit sad to write it out like that~~
