Was that message sent toward the present day apparent position (which
is the position of M13 some 25,100 years ago --distance to M13:
25,100 light years; angular diameter: 20'), the present day actual
position of M13 (as projected 25,100 years future-ward from its
current apparent position, and from what is known of its motion,
gravitationally driven, but hardly "orbital"), or perhaps in the
direction of its projected position 25,100 years into the future,
which is to say 50,200 years future-ward from its 1974 apparent
position? (Which doesn't even consider the putative accelerative
nature of cosmic expansion, or the influence of dark matter.)
Sounds like a game of cosmic whack-a-mole.
