The proper time of a photon which always has a lightlike wordline is zero, correct? Does this mean from the perspective of light (which doesn't have any conscience to have a perspective) that it travels instantaneously in zero time. So while we see light from Alpha Centari and can watch it travel for four years to get to earth, it thinks it traveled from Alpha Centari to Earth instantaneously?
