I'll defend by pointing out that Maxwell's equations contain that nasty speech of light limit. :)
It still gave a lot of bang to information exchange, compared to, say, Pony Express. :lol:

Yes. It is an interesting paradox that the new speed limit came with improved communications. Now that we have that limit we have to live within it.

Also came to mind, sending signals to 1000 light years away probably takes an amount of energy we wouldn't help noticing?
