If I’m understanding, a theoretical ball thrown at 1c would follow the same path as a photon?

Yes, although you can't actually get anything with mass to travel at 1c (subject to our current understanding of physics).

As I understand it, the only thing that can travel at c are:
* photons
* spherical, massless cows in a vacuum

Not sure about cows. I bet a thing traveling at c might not exactly have 3 spatial dimensions.

Agreed ! The "spherical cow", has to first become a circular cow /s

Anything massless travels at
c
, not just photons.
