Theoretical physics does not require visibility.

Interesting are phenomenons which exist, whether they are visible or not.

E.g. a ship on the other side of the planet cannot be seen from here or 
the other side of the Moon.

But both do exist.

Visibility, usefulness or other categories of this kind, which reflect a 
connection to the observer, are irrelevant in physics.

They are important for you, however, but you are not important for physics.
