<p>What would be the #1 hardest ever theoretical physics branch/field there is? I was thinking more along the lines of string theory, or particle theory? I am not talking about applied physics such as astrophysics, or fields in astronomy, but we could talk about theoretical astro, or things like that. Would a college, or university offer these parts of physics to see what would be required to earn such of a degree?</p>
<p>I believe Super FYZYX is the hardest branch.</p>
<p>It depends on what is hard for you. I know some physicists who are brilliant but couldn’t do an experiment right if they had step-by-step instructions. As far a theoretical physics goes, the same tools are often used in condensed matter physics as well as particle physics so I am not sure I can give you a ranking. What you choose to study depends on what is exciting to you.</p>
<p>Now for your second question about a university offering such a degree. If you are asking about a Bachelor’s degree, then no. There are no theoretical physics Bachelor’s degrees. The bachelor’s degree is both theoretical and experimental and is pretty much the same at any university in the world. The specialization into experimental, theoretical, computational physics happens in graduate school, when you are getting a Ph.D.</p>
