inertia: a tendency to do nothing or to remain unchanged;
"the bureaucratic inertia of government"
Photons don't have an inertial frame of reference, so they don't experience time; and if they don't experience time, it means they don't move at all and in fact their "world" is more like a single point rather than the universe we see around us. So, if that is true, "where" are photons relative to us? And how are we interacting with them?
