The discussion centers on the relationship between the Schwarzschild metric and particle absorption, highlighting that these concepts belong to different realms of physics: general relativity and quantum field theory (QFT). Participants clarify that particle collisions are not modeled as gravitational processes, indicating a clear distinction between the two theories. The conversation emphasizes the necessity of studying advanced quantum mechanics before tackling QFT, particularly QFT in curved spacetime, which is significantly more complex than standard QFT.
PREREQUISITESStudents and researchers in theoretical physics, particularly those interested in the intersections of general relativity and quantum field theory, as well as anyone studying the Schwarzschild metric and its implications in modern physics.
Are you talking about particle collisions in curved spacetime?accdd said:
If you don't know what question you're asking how can anyone answer it?accdd said:
Not really. One is the theory of gravity; the other is the quantum theory of particle collisions. Particle collisions are not modeled as a gravitational process!accdd said:
QFT is more advanced than GR in my opinion.accdd said:
I went to see a psychic. She asked me "what seems to be the problem." I replied "you tell me!"PeroK said:
No.accdd said:
From which source? Textbook(s)? Formal Course? Pop-sci fluff?accdd said:
Since you mentioned "curiosity", I'll risk telling you that they're "related" only in a vague sense that in the vicinity of the Schwarzschild horizon there's a phenomenon called Hawking Radiation. This is an advanced topic, requiring knowledge of QFT in Curved Spacetime (which is far more difficult that ordinary QFT -- which is itself one of the most difficult areas of theoretical physics).accdd said:
Yes, but try advanced QM first (see my signature line), then introductory QFT, then advanced QFT, then try QFT in curved spacetime. That should keep you gainfully occupied for many years.accdd said:
