I was actually thinking ๐ค...hmm this would be the best way to tell some other civilization that we live in this planetary system....get a mirror big enough to point a beam out of its normal trajectory in some sort of non random fashion. Basically smoke signals using a mirror.
I think this would take way to long to travel somewhere where things acutally live the light will probably only reach them long after humanity is gone.
