- Light travels at different speeds depending on the density of what it is traveling through. In a vacuum, such as space, it travels at 186,282.397 miles per second or 299,792,458 meters per second.
- It takes 499.0 seconds for light to travel from the Sun to the Earth, a distance called 1 Astronomical Unit.

How long in years to travel 1 ght year?
if you're asking "how long in years to travel 1 light year" you would have to know how fast you are traveling. a light year is a measure of distance that's equal to approximately six trillion miles...
How fast would it take to travel one light year at the speed of light?
It would take light one year to travel one light year. (The answer comes from the definition of a light year.) We cannot go that fast; only light can. Relativity confuses matters slightly. If you travel one light year at the speed of light, an outside observer would say it took you one year. You yourself would say the trip was instantaneous. Since, as noted above, you can't possibly go that fast, if we say that you were merely very very close to the speed of light, you'd say it took a much shorter time than one year; the exact length would depend on exactly how fast you were going. (Even more confusing: by your measurements), you wouldn't have gone a light year at all, but some shorter distance. Again, exactly how short depends on how fast you were going.)

What is darkness and how fast does it travel?
Darkness is the absence of light and will therefore travel at the speed of light (6x108m/s)
