Now Two Thumbs, if a light year is meaningless and cannot be referanced, then how did you come up with the miles?
Selivan, why do you think that you know enough to say anything like that? I suspect what you know in physics will compare to the physics of a hundred years from now about the same as what a neolithic hunter knew of transistors.
it's called math.
crap, now I have to figure out if I remembered right
A light year is 5,878,625,373,183.6 miles
and it's 4.2 light years away
carry the one
My Dad would probably stop twice to pee, so really really far away.
you can't visualize a light year, you have no concept or point of reference. so the idea of travelling there is absurd.
