what major to pick

i, am worried about my major. not really how i am going to complete. but that its not going to be enough for me. my major at the moment is aeronautical ( or aerospace) engineering and i dont wanna just learn that. so im considering actually taking physics as a double major. i love science and math and i dont like the ideal of just limiting my options and just sticking to one field the rest of my life. i still want to learn everything i can about biologoy and chemistry, so i feel like choosing one job title sucks. so ifeel that a double major at the moment would be the best option in obtaining what i want.
