In space, no one can hear you scream — because sound doesn’t travel in a vacuum, but also because you would need some sort of radio relay to carry the message, what with the distances being so extreme. And this goes for any sort of communication. Snapshots of Pluto’s heart, photos from Mars, images of a hellflower bouquet at Jupiter’s north pole: All of it streams back to Earth in a trickle via radio waves, a weak form of light.
Space Communications Are Stuck In The Dial-up Age. Which Means It’s Time For More Lasers.
