So if the radio wave is 1.5 Billion light years away, then that signal is 1.5 Billion years old if Einstein is right (nothing can travel faster than the speed of light). If those aliens are real then maybe they are extinct after 1.5 Billion years.

I guess the real question is was Einstein right, other wise the signal could be live.
