Sorry I’d im way off here. But if we are looking at other systems and galaxies such as the andromeda system, why should we expect contact? If the light we are seeing from andromeda is two million years old, wouldn’t any communication take much longer?

As far as distant galaxies go, we don’t seriously expect contact in the sense of two-way communication, just aspire to pick up signals that other intelligent life might’ve sent out long ago; and likewise send out our own signals that maybe intelligent life picks up on far in the future. It’s more an academic research venture than a real short-term attempt to communicate. Any life we may truly discover and communicate with during our lifetimes would have to be somewhere else in the solar system that the explorer probes pick up on.
