Radio waves travel at the speed of light.It would probably be great to have a universal way of communicating at the speed of light. But, even this would not guarantee us the opportunity to communicate with extraterrestrial civilizations. Since they really can be at such distances (if they, of course, exist) that are inaccessible for our lifetime.
Now we cannot even instantly communicate with each other on our planet. Although many companies are trying very hard.
I wonder how much satellites could help in achieving fast interplanetary (at least) communication?
My point about making the trip to somewhere like Alpha Centuri is IF we could perfect quantum communications and had someone to talk to there, then we could in theory send messages/images/video at faster than light speed by modulating entangled particles, this would also be digital and in theory not require any real power, if we could perfect quantum communications via. entangled particle modulation we could talk to people on the opposite side of the Earth, in submarines, on the moon, ect... instantly, digitally, without any need for encription or powerful transmitters.......I have serious doubts about the spooky actions at a distance of entangled particles being useful in this way or over great distances, but it would be a big leap forward and lead to more as we learn why this works this way and build on that knowledge.
