With C being the fundamental limit (speed) of communication, "talking" with another race would be quite impracticable. Not much of a conversation if you have to wait 3000 years for a reply to your hello.

Can you imagine the first interstellar post card we get back from the space aliens after we contact them.... we wait 3000 years for the response, and finally it arrives. We hurridly translate it, only to discover that it reads: "Having a good time; wish you were her."

What a bummer, man!

What a bummer, man!

Bummer indeed! Hmmm... Think the party would still be going strong after 3000 years? :-)
