At least its more interesting when you put it that way.
I read each panel wondering, did my computer crash a nanosecond ago?
Actually the speed of light is around one foot per nanosecond*, so around 2 ns ago, your present light was a mere 2′ away.
If my overhead bulb went out, it would probably be at least 6 to 8 ns before I found out. Tenuous, and possibly tenebrous, indeed!
