I love space and I would like to go into a major related to space, like astrophysics, but I am not very literate with computers and I was wondering if I need to grit my teeth and learn about computers or if there is a space related major not dealing with computers?
You need to grit your teeth and learn about computers.
The logic and symbolic language in itself is useful to you.
Computers are a necessary tool and programming is an important part of any such degree.
