Re: Weird question...



From a practical point of view, you could not have any appreciable effect
on a 2 lyr long rod, it would be to massive. However, since a 2 lyr long
rod is not practical anyway -- you can not move the whole rod at the same
time. Any pressure on one end would result in a compression of that end
which would propagate at the speed of sound in that material, which is
much, much less than that of light. So light gets there first.
