On the other hand intergalactic communications are probably conducted through control of "entanglement". Lot less noise that way, and it's FASTER!

Probably so. Other than inadvertent transmissions of TV and radio signals from similarly advanced alien worlds, it's likely a truly advanced alien civilization has discovered an equally advanced form of communication.

After all, to any humans living in, say, the 1500's, our technology would appear to be magic. If someone from the 1500's had even contemplated other worlds and how to contact them, they might have suggested signal fires, shooting lighted arrows into the sky, or perhaps setting out stones in large patterns on the ground. We may be bombarded with alien transmissions, but they are as invisible to us as radio waves would be invisible to a person living in the Dark Ages.

Perhaps Neutrino Communications is the way to go?
