10. Are you relying on the assumption that faster-than-light signals can be sent?

It could turn out that they were originally broadcast 500 years ago, which would mean ours first transmission would still not reach them for another 400 years.

Is the following controversial? Is there reason to suspect that astronomers are failing to see what is very close?

Discovered in 1994, the Sagittarius Dwarf Elliptical Galaxy held the previous record for closest galaxy, at 75,000 light years away.

The Canis Major Dwarf Galaxy is about 42,000 light years from the galactic center, and a mere 25,000 light years from us (which puts it closer to us than the center of our own galaxy, which is 30,000 light years away from the Solar System).

Compare a drop in the record from 75,000 to 25,000 (cutting down by 2/3) to a hypothetical drop from 25,000 to 500 (cutting down by 98%).
