    Self study physics
AI Thread Summary
The discussion centers on seeking advice for advancing in self-directed STEM education, particularly in physics. The individual has a solid foundation in special relativity, general relativity, and quantum mechanics, having pursued a non-physics STEM degree and continued studying these subjects independently. They express satisfaction with their understanding of these areas and have recently engaged with Max Tegmark's work, which aligns with their interpretation of physics. The user is contemplating exploring theories beyond the standard model, specifically loop quantum gravity (LQG), topological quantum field theory (TQFT), and twistor theory, but is uncertain about where to begin. They seek guidance on how to proceed with their studies and whether their interests are premature. The discussion emphasizes the importance of direction in self-study and the relevance of foundational knowledge when tackling advanced theories in physics.

So I hope I'm posting in the right place. This is a request for advice on my STEM education but I have no immediate intention of attending university again (maybe one day). Rather, I'm requesting guidance on the future direction of my independently driven academics (i.e. "self-study").

I created this account back in 2005, while I was still in high school. I asked a bunch of questions, trying to wrap my head around SR (when I have time, I'm sure I'll get a good laugh by going back and reading what I wrote). I eventually figured that out and moved on to GR and QM and have gotten a pretty good handle on those things. In the meantime, I got a non-physics STEM degree, a job outside of physics, and continued to study math and physics in my spare time. There's still plenty for me to learn wrt GR and QM (more the latter than the former) but I'm satisfied with my grasp of them. I think the MWI paired with QFT and an extreme focus on the role of information and computable processes works very well. Finally gave in to the suggestions that I read Tegmark's book about the MUH and I've found the book to be a fairly precise explanation of my interpretation of physics (though it's been wonderful to read the additional insights he offers). I find that the holographic principle, AdS/CFT correspondence, the Beckenstein bound, the Landaurer principle, the delayed choice quantum erasure experiment, etc, etc all put writing on the wall that I can't quite read.

So my question: where to go from here? I'm thinking of diving into some of the theories beyond the standard model. I've heard that I should consider LQG, TQFT, and/or Twistor theory. But I'm not sure which of these I should start with. Given my background and preferred perspective, where should I begin my investigation forward? Am I getting ahead of myself?

Thanks in advance for any advice you can offer.

Why do you want to investigate BTSM theories in the first place?
 
Hey, I am Andreas from Germany. I am currently 35 years old and I want to relearn math and physics. This is not one of these regular questions when it comes to this matter. So... I am very realistic about it. I know that there are severe contraints when it comes to selfstudy compared to a regular school and/or university (structure, peers, teachers, learning groups, tests, access to papers and so on) . I will never get a job in this field and I will never be taken serious by "real"...
Yesterday, 9/5/2025, when I was surfing, I found an article The Schwarzschild solution contains three problems, which can be easily solved - Journal of King Saud University - Science ABUNDANCE ESTIMATION IN AN ARID ENVIRONMENT https://jksus.org/the-schwarzschild-solution-contains-three-problems-which-can-be-easily-solved/ that has the derivation of a line element as a corrected version of the Schwarzschild solution to Einstein’s field equation.
