How does it work, traveling at light speed means you reach your destination via curved space, getting home before you left?
Does the sun's light reach the earth before it leaves the sun, or is it eight minutes old?
Can we see the billion year old sunlight?
Have you recommended reading?
Define what you mean by "timeless".If it is a statement like: the affine parameter describing a null geodesic cannot by an affine reparametrisation be understood as the time measured by a standard clock moving along the null geodesic, then yes, photons are timeless.The problem is that the space-time interval for null geodesics, that is the paths of light is always zero. This messes things up.
I doubt this is a useful concept, but is as close to "photons being timeless" as I think we can get.
