i seem to be finding so many diff definitions...>.<

anonymous · Answer

I believe a light year is the distance that light travels in a year.  It doesnt matter if its going to earth or not.

anonymous · Answer

No it's a unit of distance. It's the distance light travels in a year.

anonymous · Answer

Unless there is the special relativity business

anonymous · Answer

So....uhm

anonymous · Answer

Its a distance.  Not a length of time.  Thats it.

anonymous · Answer

So assuming the star is N lightyears from the earth, it takes light N years for the light to reach us from that star. By definition.

anonymous · Answer

so then my statement was false...? sorry...

anonymous · Answer

Yes. False. It was false as soon as you said "Is a lightyear the time it takes..."
Because it's not a unit of time. It's distance.
