Why is it said that light can travel through empty space?

A photon travels in a vacuum from A to B to C. From the point of view of the photon, are A, B, and C at the same location in space and time?

Galilean transform as limit of Lorentz one

Does special relativity imply that I can reach a star 100 light years away in less than 100 years?

Do bats use special relativity when they use echolocation?

Two formulas for relativistic energy - what is the difference?

Is the Lorentz group $O(1,3)$ irreducible, i.e. simple?
