Should I major in Physics & Astronomy or Physics & Math?

[gracetomasi]

I'm currently in my first year of a combined major in Physics and Astronomy. I'm hoping to study theoretical cosmology, and get a PhD in physics. I've been told it would be wise to get a double major in Physics and Math if I wish to study theory, but would it also be wise to get a combined major in Physics and Astronomy, and minor in math? I'm unsure of which route to take

I had a look at the 2 programs in question. It seems like the Physics & Math combined major actually requires 3 more courses than the Physics & Astronomy. If you did Astro you could use a few of your regular electives to take some of the additional math courses required in Phys/Math but it would still leave you short about 3 math courses.

Alternatively you could use some of the electives in Phys/Math to take some Astro courses leaving you similarly short about 3 Astro courses than if you had done the Physics/Astronomy double major.

I didn't check the requirements for declaring a minor, but in Phys/Astro you get 6 free electives with 3 being in first year and for Phys/Math you get 5 free electives with 3 also being in 1st year. Does that give enough credits to be able to declare a minor? Either way the question basically becomes which would be more valuable: being able to take 3 additional Math courses or Astronomy courses?

I believe if I chose to minor in either math or astronomy, I would most likely meet the requirements for acquiring a minor. I'm leaning towards a minor in math and a major in physics and astronomy, but I am concerned that I may feel behind in the math area once I enter my master's.

I would be less concerned about the actual certification names and more concerned about which courses best prepare you for your goals.

My understanding is that astronomy/astrophysics/cosmology programs for the most part don't actually require a corresponding bachelor's degree for admission and that a "regular" Physics degree is sufficient. In practice however I don't know if admissions committees would give greater preference to a student with astronomy/astrophysics courses on their transcript or not.

I would recommend speaking with an academic advisor at your university as you actually have a number of options for combining Physics, Astronomy, and Math courses including:

Combined Major - Physics & Astronomy
Combined Honours - Physics & Astronomy, Physics & Math
Joint Honours + Major - Physics Honours & Astronomy Major, Physics Honours & Math Major
Minor - Math

I would look at the options at the course level - which will give you access to the important math, physics, and astronomy courses required for theoretical cosmology.
If it was me, I would take a less demanding major option (like "just" physics) but then pack my electives with all the important math/astronomy/physics courses. This would allow me to take what's important while not taking what isn't as important.

PhD grad admissions committees will look at your courses (and research of course), not just your degrees.
