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:

en.wikipedia.org/wiki/Problem_of_time

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?

study temporal logic op

>Mathematics.
This.

If your college isn't shit, find your academic adviser, form a relationship with him and see if he'll take you under his wing to help you out in your desire to study time. Regardless, getting your foot in some branch of physics will lead you where you want to go.

...

If you want to study time, you need Special and General Relativities. That'll get you started on the most fundamental geometry of it.
But if you want to go deep on this, you may need other things, depending on your taste in research:
For the orientation of time (specifically, why the future is not the past) you'll need some theoretical statistical physics, specifically how to define entropy, especially in weird cases like out of equilibrium systems, or "gravitational entropy" whatever that is (which is specifically about trying to understand the "arrow of time" in the context of a curved space-time)
For the measurement of time, there are some important things in Quantum Physics, like understanding atomic clocks, theoretical limits on the uncertainty of measurement of time, the weird shit they're up to in the Montevideo Interpretation of Quantum Mechanics (though that specific one may be a little marginal), and non-abelian generalizations of differential geometry.

>Wasting time to teach concepts literally a 3 year old already understands
Please just just

Thanks user, now I know what to focus on

literally a friend i had and decided i was retarded long ago.
fuck you miguel, im going to change the fucking world with my coding so just fuck you.

"What area of physics can I study time?"

what? can you english? is it me or is this poorly formulated?

shouldn't it be

"what area of physics studies time?"

lrn2words plz

Love,

user

retards change the world all the time retard

I meant what area of physics should I go into to study time user.

None that will teach you anything useful.
The study of EMR propagation, not sure what field you'd actually find that, probably theoretical physics. Bam time is the difference in intersecting fields of EMR

Trump being the greatest example.
