The original question was: Given that light is moving at light speed, and time slows down as a massive object approaches the speed of light, does light travel through time? If light doesn’t travel through time, how does anything make sense, since clearly light moves but movement is dependent on time? There are some things that behave differently when investigated from an “approaching light speed” way of thinking and the “being at light speed” way of thinking. When something travels at the speed of light it really doesn’t experience any time. This may not make sense, and it’s a little mind bending, but consider this:Movement isn’t dependent on the time experienced by the moving thing, it’s dependent on your time.
