If we want to communicate with other civilisations, it turns out that the laws of physics, the nature of interstellar space and a little common sense place surprisingly strict bounds on how this communication can take place.
My favorite bit:
In addition to this, says Messerschmitt, a good idea is to exploit the laws of physics and in particular Shannon’s mathematical theory of communication, which determines how much information can be sent to a noisy channel the certain power level. stop
Yes, to a noise channel the certain power level. stop
