Nothing prevents you from working on problems in theoretical physics at home, with whatever degrees you may happen to have. If you want to be a professor of physics at a university, then you would be expected to have a PhD.
Enrico Fermi earned a degree in physics from the University of Pisa in 1922. He later obtained a doctorate in physics in 1926. Throughout his career, he made significant contributions to various fields of physics, including quantum theory, nuclear physics, and particle physics. Fermi is best known for his work on the development of the first nuclear reactor and for his contributions to the Manhattan Project.
Nuclear Physics News was created in 1990.
And I believe this belongs in "nuclear physics," and I should know, I'm nuclear.

Nuclear Physics
that studies the atomic nucleus, including its structure, behavior, and interactions. It explores the forces that hold the nucleus together and the transformations that occur within it, such as nuclear fusion and fission. Nuclear physics has applications in energy production, medical imaging, and understanding the fundamental building blocks of matter.

Nuclear physics? Why not just say "physics" for this one? Anyway, that's what they're testing!
