Other Physics Graduate Study - Which Area?

AI Thread Summary
The discussion centers on a prospective PhD candidate in theoretical physics seeking guidance on selecting a research area. The individual has a strong academic background, including studies in quantum field theory, general relativity, cosmology, and particle physics, and is looking for advice on promising fields for future research. Key areas of interest include cosmology, black holes, mathematical general relativity, quantum gravity, and the nature of dark matter and dark energy. There is a desire to avoid overly competitive or stagnant fields, such as experimental particle physics and string theory. The candidate seeks recommendations on effective methods for discovering a viable research area and insights into which topics are currently worth pursuing to make a meaningful contribution during their PhD. The discussion emphasizes the importance of aligning personal interests with emerging trends in theoretical physics to ensure a fruitful research experience.

Hi everyone,

For many years I have been planning to become a theoretical physicist. If everything goes well, next year I will be graduating with a MMath, having studied QFT, GR, cosmology, particle physics, black holes, differential geometry, etc. This fall I am going to apply for a PhD in theoretical physics. My primary concern and a cause of significant uncertainty is the area of future study and research (I think it is reasonable to assume that the choice of area will define the institutions where I am going to apply) and therefore I would like to ask the wise community of this forum for suggestions and guidance related to finding or creating the main area of interest. :)

Do you think, for example, that reading reviews of the major topics in physics journals will be optimal? Moreover, which of the following fields do you think are worthy of pursuing? Which of these are promising and which of them - dead or too competitive?

Some of the topics in which I have interest:
Cosmology, Structure, with some aspects of Astrophysics
Cosmology, Inflation, the Early Universe
GR, Black Holes
Mathematical GR, twistors, non-commutative geometry etc.
QFT, physics beyond SM (symmetry breaking, axions?)
Quantum Gravity
Nature of DM and DE

Topics in which I have slightly less interest:
Experimental Particle Physics
String Theory
Foundations of QM
Supersymmetry
...something else?

I don't mind if some of my work involves numerical methods, but as this is not something I love doing, things like computational GR are not for me, I think.

So, to summarize, my questions are:

1. What should I do to discover a promising area?

2. Which area is worth pursuing at present - so that I could contribute something to it in the course of my PhD? :)

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.
