Not in the appropriately modified version of LET relativity. In
that case it is no more interesting than traveling faster than sound.

Regardless of the time on the clock you won't see him getthe message until after you have sent it." I am observing 3 things in your spaceship through my normal telescope:
1) I observe you receiving my message
2) I observe that when you do receive my message you immediately turn your head and look at your clock.
3) I observe that when you turn your head your clock (not mine) says 1PM.
You, your head, and your clock are all in the same reference frame relative to me,
so I can say that when you received my answer you saw your clock (not mime) say 1PM, and we know that when you asked the question you saw your clock (not mime) say 3PM, so you got your answer 2 hours before you asked the question, and that poses a problem for those who would prefer that the universe make some sort of sense.
And it really doesn't matter if Einstein was right or wrong because we know for a fact that this time dilation effect is real, its been demonstrated experimentally countless times; as long as messages can not move faster than light time dilation is no problem, answers can never arrive before questions, but if you can send signals faster than light the world becomes very strange indeed.
