Light is moving so much faster. In the same two seconds it crosses a much larger distance in space.

The line is only straight in spacetime, not in space.

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
