Of course it does. The sun is not subject to man-made instruments, we can't travel there, we can't affect it, yet we can study it.
To a limited degree is, because it and it's effects are observable and part of our reality.
Could we study it 1000 years ago? how about 2000 years ago? 3000? to what degree?
How well do you think we will be able to study it 1000 years from now?
How much will our understanding of reality as we know it, change 1000 years from now?
