All of them.

Start with relativity.

Special Relativity and General Relativity

But what should I major in university to study relativity and time? Astrophysics?

Check which courses are available in each topic and see if relativity comes up. My university's General Relativity course is part of an astrophysics module but it could just as easily be part of a theoretical physics course Most good undergrad courses in any kind of physics will probably do a component on Special Relativity because it's about the right level, for GenRel that's usually more at a specialised Master's level because there's a lot of pretty hard maths that comes with it.

You'll probably want to learn quantum mechanics too because one of the big problems in physics at the moment is the disconnect between the concepts of time in quantum theory and relativity, see:

I'd recommend majoring in just physics or theoretical physics, astro comes with a lot of bullshit. That said, check university websites to see what courses you should take as prerequisites to keep your desired options open. Also keep in mind that your interests can change a lot while at university.

Thanks user, this was pretty helpful. I will probably just major in theoretical physics and then try to choose as many relativity courses as possible.

Mathematics. Take linear algebra, modern geometry, complex variables, analysis, topology, abstract algebra, analysis on manifolds, smooth manifolds, and Riemann geometry.

you want to study an illusion?
