Is Light Traveling Through Time?

[Physicsislifetome]

If we need light speed to travel in time and light already have it , so is light traveling in time

I don't know what you mean by "travel in time", but light takes time to move from one point to another.

Maybe he's thinking light speed allows time travel, so is asking if light engages in time travel.

Saying "it takes time to move from one point to another" may apply to Bob, who will say it takes him some time to go from home to work (taking time being his experience), and Bob may notice that his clock shows the passage of time when he notes the emission and absorption of light as the light apparently needs some duration by Bob's measurement to move from one point to another... but that is Bob's time. Isn't the current thought that since there is no inertial reference frame where light goes less than light speed c it is not just that light's delta t=0 but that it is null? That there is no sense of time that can be applied to the light itself?

Maybe we should let him tell us rather than guess.

Bahamagreen is right
