UCL Natural Sciences vs. Manchester Physics with Astrophysics vs. Edinburgh Physics –

Hi, I believe that, in your case, the content of the course is more important than the university's ranking. UCL's Natural Sciences, Edinburgh's Physics, and Manchester's Physics with Astrophysics are all excellent programs. You can't go wrong with any of them.
Have you attended any offer holder days? These events can provide valuable insights into the course structure and university environment.
UCL is renowned for its research excellence, having produced 32 Nobel laureates. Edinburgh and Manchester are also highly respected institutions with strong physics departments.
I suggest reviewing the course content and considering the atmosphere of each university to determine which aligns best with your interests and goals.

Not really sure what you mean about astrophysics involving a lot of statistics...? I don't think it has particularly more than any other area of physics (and theoretical astrophysics I would expect somewhat less?).
In the UK most physics degrees (whether called "Physics" or "Astrophysics" or "Physics with Astrophysics") cover largely the same core content. Particular "specialisms" just have some optional elements "preselected" for you, although it's usually straightforward to swap to the "main" physics course for these (note this is not necessarily the case for joint or combined honours courses like natural sciences).
If you want to be a physicist realistically you just need to aim to do a physics degree, or perhaps a joint honours physics and maths course. Particularly if aiming for theoretical physics areas you probably just want the ones that give you as many mathematical options as you can take. It's not about the name of the course (i.e. "astrophysics" vs "physics") it's about what you studied on them. If you want to do general relativity and black holes and didn't take any GR options for example then that might be a bit puzzling even if your degree name is "astrophysics".
I would suggest realistically that the UCL course does not align with your long term goals. If you have fleeting interests in earth sciences or chemistry, I'd suggest just reading about those areas while doing a full physics course. The choice between the other two is up to you, as I stated content is likely to be very similar between the two so I'd consider more the differences in the universities and towns themselves.
Note in terms of your complaint about the Edinburgh course taking 4 years - students aiming for a PhD in the UK would usually do an MPhys or BSc + MSc anyway, and in England an MPhys is 4 years.

Thank you for your reply! I thought astrophysics involving a lot of statistics because some senior students told me so…… they said astrophysics involves a lot of data and you need to analyse them. So statistics and programming skills are really necessary. Besides, thank you very much for advice on chemistry and earth science. I decided to go to the university of Manchester because i prefer the atmosphere of Manchester. Thank you for your advice

Thank you for your reply! I attended a webinar held by the physics department of the university of Manchester and i feel that the professors are really patient. And i also like the atmosphere of Manchester. So i decided to go to the university of Manchester. Thank you for your advice!

I’m so glad you’ve found the right course and made your decision. Wishing you all the best with your studies at Manchester!
